Introduction and basic information of Nb IOT low power lpwan network

Source: unknown Editor: admin Time: 16:14, May 14, 2019

NB IOT basic information
  
Narrow band Internet of things (NB IOT) has become an important branch of the Internet of things. NB IOT is built in cellular network and consumes only about 180khz bandwidth. It can be directly deployed in GSM network, umts network or LTE network to reduce deployment cost and realize smooth upgrade.
  
NB IOT is an emerging technology in the field of IOT. It supports the cellular data connection of low-power devices in Wan, also known as low-power Wan (lpwan). NB IOT supports efficient connection of devices with long standby time and high network connection requirements. It is said that the battery life of Nb IOT equipment can be increased by at least 10 years, while providing very comprehensive indoor cellular data connection coverage.
  
Huawei is the first to promote the development of IOT standards. In May 2014, Huawei proposed narrowband technology NB M2M; in May 2015, nb-ciot was formed by integrating NB OFDMA; in July, nb-lte and nb-ciot were further integrated to form nb-iot; it is expected that nb-iot standard will appear in 3GPP R13 and freeze in June 2016.
  
Previously, compared with nb-lte promoted by Ericsson, Nokia and Intel, Huawei has paid more attention to the construction of nb-ciot ecosystem, including mainstream operators such as Qualcomm, Vodafone, Deutsche Telekom, China Mobile, China Unicom, bell and other mainstream operators, chip manufacturers and equipment system industry chain all joined the camp.
  
Nb-iot focuses on the low power and wide coverage (lpwa) Internet of things (IOT) market, which is a new technology that can be widely used in the world. It has the characteristics of wide coverage, multiple connections, fast speed, low cost, low power consumption and excellent architecture. Nb-iot uses the license frequency band, which can be deployed in band, protected band or independent carrier to coexist with the existing network.
  
1. Future advantages
  
Mobile communication is moving forward from the connection of people to the connection between people and things, and things to things. The interconnection of all things is an inevitable trend. However, the current 4G network is insufficient in the connection between objects. In fact, compared with Bluetooth, ZigBee and other short-range communication technologies, mobile cellular network has the characteristics of wide coverage, mobility and Dalian access, which can bring more abundant application scenarios, and should become the main connection technology of the Internet of things. As an evolutionary technology of LTE, 4.5g not only has a peak rate of 1Gbps, but also means more connections based on the cellular Internet of things, supports massive M2M connections and lower delay, which will boost the rapid popularization of HD video, volte and Internet of things applications. The cellular Internet of things is opening up an unprecedented broad market.
  
For telecom operators, Internet of things applications such as Internet of vehicles, smart medical, smart home will generate massive connections, far exceeding the communication needs between people.
  
NB IOT has four major characteristics: first, wide coverage, which will provide improved indoor coverage. In the same frequency band, Nb IOT gains 20dB compared with the existing network, which is equivalent to 100 times of the coverage area; second, it has the ability to support massive connections. One sector of Nb IOT can support 100000 connections, supporting low delay sensitivity, ultra-low equipment cost and low device power consumption And optimized network architecture; third, lower power consumption, the standby time of Nb IOT terminal module can be as long as 10 years; fourth, the cost of module is lower, and the enterprise expects that the single connection module will not exceed $5.
  
Nb-iot focuses on the low power and wide coverage (lpwa) Internet of things (IOT) market. It is a new technology that can be widely used in the world. It has the characteristics of wide coverage, multiple connections, low speed, low cost, low power consumption and excellent architecture. Nb-iot uses the license band, which can be deployed in band, protected band or independent carrier, and coexists with the existing network.
  
Because of its low power consumption, wide coverage, low cost and large capacity, Nb IOT can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, intelligent parking, intelligent agriculture, etc.
  
Many operators, including China's operators, are carrying out NB IOT and research. In terms of the development status of Nb IOT, Yu Quan elaborated three wonderful views in detail: first, Nb IOT is an important opportunity for the cellular industry to cope with the interconnection of all things. Second, Nb IOT must establish an open industrial platform to succeed. Third, 2016 is a very critical year for the Nb IOT industry, and standards, chips, networks and commercial application scenarios will be mature.
  
2. Demand development
  
With the advent of intelligent city and big data era, wireless communication will realize the connection of everything. Many enterprises predict that the number of Internet of things will be 100 billion level in the future. However, a large number of short-range carriers such as Bluetooth and wireless carriers have emerged. In order to meet different business requirements of Internet of things, according to the business characteristics of Internet of things and mobile communication network characteristics, 3GPP has carried out technical research on enhancing mobile communication network function according to narrow-band service application scenarios, so as to adapt to the booming business needs of Internet of things.
  
We are entering the era of Internet of things (IOT), which is a great opportunity for the whole mobile communication industry. This is undoubtedly demonstrated in mwc2016. Both operators and equipment giants have demonstrated complete Internet of things solutions and applications in different vertical industries.
  
Of course, the foundation of all this is the ubiquitous network connection. The network of operators is the most extensive network in the world, so it has unique advantages in the access ability. However, a reality that can not be ignored is that only 10% of the total number of connections are actually carried on the mobile network, and most of the object to object connections are carried by Bluetooth, WiFi and other technologies.
  
For this reason, the industrial chain began to study the use of narrow-band LTE technology to carry IOT connection several years ago. After several renaming and technology evolution, 3GPP officially named this technology NB IOT in September 2015. It was the first time for the company to make its debut on nbiot and its operators.
  
Yu Quan, Chief Strategic Officer of Huawei's wireless network product line, said in an interview with the communication industry daily (Network), "NB IOT is an important opportunity for the cellular network industry to cope with the interconnection of everything. We are very optimistic about the commercial prospects of Nb IOT and recommend it as the first choice of IOT connectivity technology. "
  
He explained to reporters the commercial and technical advantages of Nb IOT. From the commercial level, cellular network covers more than 50% of the global geographical area and 90% of the population, which is the most complete network. From the technical level, Nb IOT has four technical advantages. First, it has wide coverage. Compared with traditional GSM, a base station can provide 10 times of area coverage; second, massive connection, with 200 kHz bandwidth providing 100000 connections; third, low power consumption, which can work for 10 years with AA battery without charging; fourth, low cost, module cost less than $5.
  
Previously, Huawei had calculated an account with reporters. Assuming that there are about 5 million physical sites in the world, all of which are deployed with Nb IOT. Each station has three sectors, each sector deploys 200kHz, and each sensor sends 100 bytes per hour. Then, the number of sensors that can be connected to global sites is as high as 450 billion.
  
It is understood that Nb IOT can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, intelligent parking, intelligent agriculture, etc. With the first version of 3GPP standard released in June, there will be a number of test networks and small-scale commercial networks. NB IOT will stand out among several low-power WAN technologies.
  
"NB IOT presents great development opportunities in Europe and even in the world. By 2020, the value of the entire industrial chain of IOT is expected to reach 3 trillion euro, including the upstream and downstream of the whole industrial chain, such as network connection, data processing, platform application, business cooperation, etc Yu Quan said that Huawei is ready to complete the commercial use of Nb IOT in 2016.
  
Hu houkun, Huawei's rotating CEO, pointed out in his keynote speech at the 2015 global mobile broadband forum that mobile operators need to take immediate action to seize the fast-growing market share of the Internet of things. Although operators have unique advantages in terms of accessibility, many other technologies, such as ZigBee, Bluetooth and built-in WiFi, are also developing rapidly, so operators must compete with vertical industries fiercely. Hu houkun stressed that it is necessary to quickly formulate unified standards for the Internet of things to promote cross industry development.
  
Luke ibbetson, head of research and development at Vodafone, agrees. He pointed out that 80% - 90% of IOT devices are connected by low-power indoor systems, and the rest are connected by cellular networks. Many people believe that the new lpwa (low power wide area) technology has low cost and wide coverage, which will bring a good opportunity for mobile operators to develop the Internet of things. However, ibetson points out, "we have not yet developed the right solution for our customers, so we are still under tremendous pressure."
  
Turn to narrowband Internet of things
  
For the narrow band Internet of things (NB IOT) used in lpwa network, operators have reached a consensus that authorized spectrum should be used, and in band and protection band should be used independently. This emerging technology can provide wide area network coverage, aiming to provide support for massive IOT devices with low throughput, cost and energy consumption.
  
In November 2015, several global mainstream operators, together with equipment manufacturers, chip manufacturers and relevant international organizations, held the Nb IOT forum preparatory meeting in Hong Kong, aiming to accelerate the development of narrow-band Internet of things ecosystem, including China Mobile, China Unicom, Etisalat and LG Uplus, Telecom Italia, Telefonica, Vodafone, GSMA, GTI, Huawei, Ericsson, Nokia, Qualcomm and Intel. Members of the six operators also announced that they would set up six narrowband IOT open laboratories around the world, focusing on narrowband IOT business innovation, industry development, interoperability testing and product compatibility verification.
  
Operators have launched pilot work of pre standard NB IOT technology among customers. For example, Deutsche Telekom and Vodafone have taken action to pilot pre deployment using existing base stations. It is expected that the trial commercial deployment will take place in the second half of 2016, and the formal commercial use will begin in early 2017.
  
Vodafone's ibbetson said he was confident in the integration of 3GPP standards, but also pointed out that the process was slow and difficult. "It is hoped that narrowband Internet of things will become an independent standard by March 2016, and we need to decide which frequency band to use as soon as possible."
  
Huawei also hopes that the relevant standards can be confirmed as soon as possible, so that the industry can start large-scale deployment of the Internet of things. "Huawei is ready in terms of technology and hopes to seize the opportunity of narrow-band Internet of things as soon as possible," Hu said
  
Narrow band Internet of things has four advantages: long battery life (more than 10 years), low cost (less than $5 per module), large capacity (a single cell can support 100000 connections), and wide coverage (covering underground).
  
Ibbetson thinks: "if the industrial chain can not reduce the cost of a single module to less than two or three dollars and realize large-scale application, the Nb IOT market will not be able to do so. We need to embed IOT modules into devices at a very low cost from a global perspective. "
  
Hu houkun also believes that in order to stimulate the large-scale development of Nb IOT, the cost of communication module must be less than $5. If the cost falls to less than $1, it will bring explosive growth.
  
Coming into the outbreak period
  
With all core technologies such as network connectivity, cloud services, big data analysis and low-cost sensors in place, the Internet of things has stepped into a stage of rapid development from its infancy, which most analysts agree with.
  
David Sovie, head of the Asia Pacific high tech and electronics industry at Accenture, pointed out that every CIO should formulate a strategy for the development of the Internet of things as soon as possible, otherwise it will be defeated in the competition. Wei sun, director of the Internet of things global strategic program at IBM Research Institute, said that IBM's big customers from all walks of life are exploring IOT products and services.
  
More and more industries have been using IOT technology to improve efficiency, improve customer satisfaction and reduce operating costs. For example, Bosch, a manufacturer of auto parts, household appliances and safety systems, has connected many product lines and has benefited directly from the rise of mobile Internet technology, especially in the field of Internet of vehicles.
  
In the medical field, Philips has developed a number of electronic medical applications, including a patch for patients with chronic diseases. The patch uses sensors to collect patients' health data in real time and transmit them to the cloud platform. Medical staff can monitor the data and take timely medical intervention measures.
  
Alberto Prado, project director of Philips Digital accelerator, points out that interoperability of equipment and systems is the key to the rise of the digital healthcare industry. With the increasing popularity of collaborative nursing model, the future medical care will integrate all resources, and take active prevention as the priority.
  
In order to meet the great opportunities in the field of Internet of things, the whole industry needs to promote not only technological innovation, but also business model innovation and cross industry cooperation. Due to the variety of use cases, applications and business models, the Internet of things market will be more fragmented than the mobile market.
  
"It will depend on the sincere cooperation of different stakeholders in the industry chain," Mr Hu said. In the era of Internet of things, operators need to expand their focus from management technology to managing the entire ecosystem. The whole industry needs to seize the opportunity and take action immediately. "
  
NB IOT needs open platform
  
"The Nb IOT industry ecosystem is growing rapidly, and it needs the sincere cooperation between operators and IOT related industry participants to make progress together." Talking about the challenges of Nb IOT landing, Yu Quan introduced.
  
Just one day before mwc2016, GSMA jointly organized the first global NB IOT summit and established the Nb IOT forum. The alliance members include global mainstream operators, network equipment manufacturers and major chip module manufacturers and many other industrial chain enterprises.
  
Yu Quan stressed that more than 20 vertical industry enterprises attended the summit, which is a very gratifying start. "Of course, there are thousands of suppliers in the industry, but there may be dozens of suppliers in the industry." Yu Quan takes the intelligent meter reading industry as an example. At present, families have many meters, such as water meters, electricity meters, gas meters and heating meters. There are many enterprises behind these.
  
With so many participants, there will be a lot of collaborative problems. The industry needs an open platform to accelerate the pace of the industry. Moreover, the development of new standards needs open platform to promote.
  
In this regard, many operators have established open lab together with telecom equipment manufacturers including Huawei. It is learned that with the help of open lab, vertical industry manufacturers can easily verify their Internet of things applications, networks and business models on the actual Internet.
  
2016 is a key year for NB IOT industry
  
"The Nb IOT standard is expected to be completed in June 2016." Yu Quan said that this shows that Nb IOT has entered a key year of development.
  
It is reported that with the 3GPP standard frozen in June, after the baptism of the market, Nb IOT will stand out in the technical competition of lpwa market and become the best choice for leading operators. At the same time, 2016 will also become the first commercial year of Nb IOT.
  
This year, many chip manufacturers and module manufacturers will support the development of Nb IOT. In terms of network, Huawei plans to launch NB IOT supporting system in the second half of 2016. Many other network equipment vendors plan to support NB IOT.
  
Operators are very urgent in developing NB IOT. "Even though the industry has tried its best to promote the rapid development of Nb IOT, operators still think that the development progress is not fast enough, which puts great pressure on suppliers." Yu Quan revealed.
  
More than 10 years have passed for the commercial terminal, and they must be able to meet the safety requirements of the industry in 2016.
  
The user case is the key to the success of Nb IOT or cellular Internet of things. Now with the help of open lab, the industry has discussed how to enable more user cases. At present, intelligent parking, intelligent water meter, intelligent tracking and other user cases have been verified in the laboratory. "It is expected that there will be a commercial network of Nb IOT in the second half of this year, and it will be deployed in scale next year. This is the general expectation of our whole industry." Yu Quan said.
  
For the challenge of Nb IOT development, Yu Quan said that everything is difficult at the beginning, but the cellular industry has developed for decades and has the tradition of open cooperation, which can achieve today's achievements. "I believe that the Nb IOT industry will repeat such open cooperation, bringing new business success to operators and vertical customers, and at the same time promoting the whole society and the whole economy." Yu Quan.
  
Help operators open 10 billion connected Market
  
It is reported that only 10% of the current IOT applications are based on cellular networks, which have coverage advantages and cost advantages. Huawei is ready to complete commercial use within 2016. Huawei said that Huawei's most critical step in the IOT market is to "help operators open a 10 billion connected market".
  
At the same time, under the advocacy of GSMA NB IOT forum, Huawei and operators jointly established development laboratories to strengthen inter enterprise cooperation. At present, it has set up six innovative laboratories in the whole world, such as nbot, Huawei Telecom, etc., which have been jointly established with nbot and Huawei Telecom in the whole world, and have been integrated with nbot and Huawei Telecom in the whole world.
  
It is understood that Huawei and Vodafone will jointly establish an open NB IOT laboratory to promote the development and promotion of Nb IOT technology. Using pre standard NB IOT technology, Nb IOT open laboratory will study network solution validation, new application innovation, equipment integration, business model research and product qualification verification.
  
NB IOT large scale commercial
  
On June 16, 2016, at the 72nd plenary session of 3GPP ran held in Busan, South Korea, Nb IOT, as an important topic of the conference, its corresponding 3GPP protocol related content was approved by ran plenary session, marking the completion of related research on Nb IOT standard core protocol which is widely supported by the wireless industry. The scale of IOT industry is about to complete.
  
With the freezing of standards, more and more industrial chain enterprises will join the Nb IOT camp, which will promote the rapid large-scale commercial use of Nb IOT. The commercial use of Nb IOT will also build the world's largest cellular Internet of things ecosystem. As a result, more commercial applications will emerge in the second half of 2016. The huge "blue ocean" market of narrowband Internet of things has been opened and will have explosive growth in the future. According to the prediction, the number of connected devices will reach 27 billion by 2020.
  
3. Large scale commercial use
  
On July 13, 2017, ofo small yellow car, China Telecom and Huawei jointly announced that the three NB IOT (narrow band Internet of things) "Internet of things intelligent lock" jointly developed by the three companies has been fully launched for commercial use. [9] It is understood that in this tripartite cooperation, ofo is responsible for the development of intelligent lock equipment, China Telecom is responsible for providing commercial network of Nb IOT Internet of things, and Huawei is responsible for chip services. This time, the full use of the commercial IOT lock has been started.
  
The intelligent lock system supporting NB IOT technology jointly built by the three companies has three major characteristics: first, it has wider coverage, and the wall penetration of Nb IOT signal is far better than the existing network. Even if users are deep in the underground parking lot, they can use NB IOT technology to switch locks smoothly, and can realize "random password" through data transmission; second, it can connect more devices, and Nb IOT technology is more than traditional The mobile communication network connection capacity is more than 100 times higher, that is to say, the same base station can connect more ofo IOT intelligent lock devices to avoid dropping the line; third, it has lower power consumption, and the standby time of Nb IOT equipment can be used for 2-3 years without charging the existing battery, which changes the previous situation that users generate electricity while cycling.
  
Four first models
  
Since 2010, Shanghai Unicom has taken the lead in carrying out the construction of "full service system" oriented by user perception, realizing the "two wheel drive mode" of enterprise development, taking "development" as the front wheel and rapidly expanding the market; taking "service" as the rear wheel, rectifying and balancing to ensure enterprise development. In five years, Shanghai Unicom has achieved excellent results in doubling revenue, doubling profits, doubling user scale, doubling network scale and increasing customer satisfaction year by year.
  
However, the transformation pressure is still huge. The mobile communication market in Shanghai is a completely saturated market, and the demographic dividend has nearly disappeared. More is to dig into the stock market, maintain existing users, provide users with more colorful high-quality content under the high-quality mobile broadband network, and cultivate the habit of using traffic.
  
At the group level, the transformation of network innovation has always been a very important topic. It has been clearly pointed out that "the transformation of network innovation can no longer be a separate network, but must be able to support market business or support model innovation".
  
In February this year, the operation and maintenance department of Shanghai Unicom and the customer collection department conducted a series of discussions on the transformation of network innovation, and set the direction on the interconnection of all things. What is the pressure on the Internet from the rapid growth of Internet? Relevant person in charge of Shanghai Unicom told c114 that the main consideration at that time was the number of connections. There is no historical data on the growth of material connection, and the scope is wide, so it is impossible to predict. In case of emergency, the signaling connection will "explode".
  
In view of this, Shanghai Unicom had in-depth exchanges with many partners. At that time, lte-m (c114 note: officially named nb-iot by ITU in September this year) came into its attention. Lte-m can effectively solve the problems of the Internet of things, and has a good development prospect in the future. Shanghai Unicom finally took this as the basis and worked with partners to deploy in the ningqiao road machine room in Jinqiao.
  
However, what business can 4.5g provide? After considering many industries, the two sides decided in April to start with two businesses, namely intelligent parking and smart water meter. The whole industry chain of these two businesses from chip maturity to downstream cooperative manufacturers is relatively mature and has good sustainability. After the business was confirmed, it entered the rapid construction process. In May and June, it was officially launched before the Asian mobile conference · Shanghai station in July, and was solemnly displayed at the conference.
  
Shanghai Unicom has more than 20 parking spaces in two parking lots on ningqiao road. All of them are equipped with monitors with 4.5g nb-iot chip and a geomagnetic induction chip. The data is first transmitted to the base station on the fifth floor, and then to the Innovation Incubation Base on the first floor. More intelligent parking function is realized through the centralized management platform of the computer room. Compared with the traditional parking scheme, the intelligent parking service has changed many problems, such as complex network deployment, multi network networking, high cost, large capacity battery and so on, which need to collect information through the relay gateway and then feed back to the base station. It can realize the advantages of one network in the whole city, easy to maintain and manage, separate from the property, and easy to address and install.
  
The current meter reading scheme has the challenges of poor depth coverage, high power consumption and high cost. By integrating a circuit board with a special chip in the water tank, the intelligent water meter business can not only realize more accurate meter reading data transmission, but also can intelligently monitor and control the water tank switch, highlighting the advantages of nb-iot technology in coverage enhancement.
  
Embrace the interconnection of all things and build a win-win ecology
  
China Unicom has rooted its experimental base of smart city in Shanghai, which has become the forefront of its exploration of smart transportation life. As early as 2011, Shanghai Unicom began to develop the Internet of things business, among which the most prominent is the application of Internet of vehicles.
  
Shanghai Unicom has built a number of integrated solutions for intelligent "Wo" transportation, from the provider of data communication transmission capacity to the provider of telematics and related services, from the provider of traditional business platform to the information platform, and even the system integrator of business platform, there are many successful cases in various fields. Whether it's BMW's "Internet driving", bus company's "smart rental", or 116114's "one click navigation", Shanghai Unicom has delivered an excellent answer.
  
As a first-class supplier of BMW's "Internet driving", China Unicom, on the one hand, provides BMW with basic 3G mobile communication services (MnO); on the other hand, it integrates its own information service capabilities and professional capabilities of other BMW suppliers to jointly provide telematisc service platform system integration (TSSP), call Center (call center) and information content service (content) )And other integrated automotive information services. This is the first time that Chinese operators have participated in telematics project as a whole service provider.
  
According to the person in charge, so far this year, Shanghai Unicom's Internet of things users have exceeded 1 million (cards), of which 40% are 3G, mainly the vehicle Internet of things; 60% are 2G, including POS machines, community lockers, etc. In the next 3-5 years, the number of Internet of things connections is expected to increase 100 times. Shanghai Unicom hopes that "network innovation can better adapt to the arrival of the era of Internet of things", and the front office department and network construction and maintenance department will participate in this field.
  
Five open laboratories
  
In February 2016, IOT will join hands with Huawei mobile to promote the development of nbiot.
  
We will research on new technologies such as nbiot, nbiot, and the application of open technology.
  
"With the commercial deployment of the technology in the coming early 2017, building an ecosystem with developers and solution providers will become critical," said Luke ibbetson, Vodafone group's R & D director and chairman of the Nb IOT forum
  
IOT (Internet of things) technology will need to extend the service life of battery more effectively. It is expected that the first batch of devices connected by NB IOT technology will appear in late 2016 or early 2017.
  
Vodafone and Huawei integrated the technology into the existing mobile network in Spain and then sent the first pre standard NB IOT message to the u-blox module installed in the water meter.
  
The trial will be incorporated into the Nb IOT Open Laboratory Consortium.
  
6. Commercial testing
  
Vodafone and Huawei both claim that the commercial test, which integrates NB IOT with existing network infrastructure, is the first test in the world to use this technology. Huawei also said that the test is only the beginning of a series of possibilities for NB IOT equipment; various enterprise applications, such as utility water meters, sensor monitoring and asset tracking, will appear in the future.
  
"NB IOT technology has been recognized by the industry," said David Wang, President of Huawei's wireless network business unit. Our joint innovation with Vodafone further strengthens our vision of providing innovative solutions to our customers, helping them meet their business needs and leading the development of technology and industrial ecosystems. We will work with Vodafone to build a more connected world. "
  
Matt Beal, head of Vodafone group's architecture and innovation division, said the demonstration demonstrated the role of operators in the field of IOT - M2M has been a successful and growing market. "Vodafone has led the development of Nb IOT, and licensed spectrum lpwa technology has been widely supported by the industry," he said. This is further illustrated by the first commercial test completed in cooperation with Huawei. Once commercial, Nb IOT will bring tangible benefits to enterprise customers, and more devices will be connected to IOT through the network. "
  
7. Market space
  
The scale of communication between people has been close to the ceiling, and the objects have just entered the fast lane of growth. With the opening of emerging markets such as wearable, Internet of vehicles, intelligent meter reading and other emerging markets, industrial 4.0, smart city, smart agriculture and other concepts have come into reality, and the era of Internet of things is accelerating.
  
The future of the Internet of things (IOT) is full of imagination. Huawei believes that there will be 100 billion connections in the world by 2025, most of which are related to the Internet of things.
  
The requirements of Internet of things for connection are very different from traditional cellular network, so narrow band cellular Internet of things (nb-iot) emerges as the times require. This emerging technology driven by the telecom industry has the characteristics of wide coverage, multiple connections, low speed, low cost, low power consumption and excellent architecture, which has great commercial potential.
  
Machina predicts that nb-iot will cover 25% of IOT connectivity in the future. For operators facing user saturation and Ott impact, nb-iot will tap into the vast new market and bring more than three times of connection growth; while for the traditional industry practitioners who are actively transforming and upgrading, it also has the inherent advantages of operators' network in terms of adaptability, network performance, manageability, controllability and reliability.
  
What is nb-iot?
  
Under the "scissors gap" of demographic dividend and traffic revenue, the Internet of things has become a new source of revenue growth for operators. Take Vodafone as an example, the number of mobile users increased by only 3%, the number of Internet of things connections increased by 33.5%, and the related business revenue increased by 24.7%. However, traditional 2G, 3G, 4G technologies can not fully meet the requirements of low power consumption and low cost of IOT equipment.
  
The birth of nb-iot is not accidental. It is the expectation of the telecom industry for the Internet of things market. Its predecessor can be traced back to the nb-m2m jointly proposed by Huawei and Vodafone in May 2014.
  
The concept of narrow-band cellular Internet of things initiated by these two companies has been widely recognized by the industry as soon as it is proposed. Subsequently, more and more industry giants such as Qualcomm and Ericsson joined in the standardization research in this direction. In order to promote the unification of standards and facilitate the industrial development, 3GPP finally reached an agreement in the ran plenary session in September 2015 to establish NB IOT as the only standard for narrowband cellular Internet of things, and started to write the agreement for work item. It is expected that 3GPP R13 will be frozen in June 2016.
  
NB IOT has significant advantages in the application of the Internet of things, which is incomparable to the traditional cellular network technology, Bluetooth, Wi Fi and other short-distance transmission technologies. First of all, its coverage is wider. In the same frequency band, the gain of nb-iot is 20dB and the coverage area is 100 times larger than the existing network.
  
Secondly, it can support massive connections. One sector of nb-iot can support 100000 connections. At present, there are about 5 million physical sites in the world. Assuming that nb-iot is fully deployed with three sectors per site, the number of IOT terminals that can be accessed will be as high as 450 billion.
  
At the same time, the power consumption of nb-iot is lower, only 1 / 10 of 2G, and the standby time of terminal module can be as long as 10 years. In terms of cost, the module cost is expected to be reduced to less than $5. In the future, with the scale effect and technology evolution brought by market development, power consumption and cost are expected to be further reduced.
  
In addition, in terms of supporting big data, the data collected by NB IOT connection can be directly uploaded to the cloud, while Bluetooth, Wi Fi and other technologies have no such convenience.
  
Nb-iot practice and achievements
  
Although the formulation of the standard has not yet been completed, the application of nb-iot has been gradually spread out and has been affirmed by all parties in practice. During MWC 2015, Vodafone and Huawei jointly demonstrated the intelligent meter reading service.
  
Guangdong Unicom actively responded to the national "Internet +" strategy, cooperated with Huawei on nb-iot, and established a joint innovation project team of Internet of things. Combined with Unicom's strengths in platform, network and operation and Huawei's advantages in standards, chips and module costs, we will jointly explore and implement the landing able Internet of things business, and integrate nb-iot technology with it through real business needs and scenarios, so as to promote the development of the Internet of things industry. Both sides chose intelligent parking, which is of great social value and relatively mature industrial chain, as the breakthrough point.
  
With the improvement of living standards in China, cars have entered ordinary people's homes, but it also brings problems such as "parking difficulty". According to the survey, every driver spends 20% of his time looking for parking spaces. As one of the developed provinces in China, this phenomenon is more prominent.
  
Users can start to search for the parking space through the app, as long as they have implemented the parking space support function in Shenzhen. Compared with the traditional parking scheme, this pilot project based on nb-iot has changed many problems such as complex network deployment, multi network networking, high cost and so on, which need to collect information through the relay gateway and then feed back to the base station, so as to truly realize the whole city with one network, which is easy to maintain and manage.
  
Similar to intelligent parking, Nb IOT has a wide application prospect in low-power Wan such as intelligent agriculture and intelligent manufacturing. Due to the high-tech requirements brought by the special application scenarios, these applications have been lack of proprietary wireless technology. Nb-iot can well fill this market gap, so as to support the development of the Internet of things to a broader field.
  
Building ecology and embracing the interconnection of all things
  
A technology from paper to business can not do without the support of a strong ecosystem. For a long time, the Internet of things connection technology has been fighting its own way, and the specifications adopted by all parties from chip to system are different, which leads to the bottleneck of large-scale deployment.
  
Now, the ecology around nb-iot has taken shape, and in the process of continuous expansion, the conditions for embracing the interconnection of all things begin to mature. At the level of network equipment suppliers, Huawei, Ericsson and other leaders have launched end-to-end solutions based on nb-iot.
  
At the operator level, China Mobile, China Unicom, Vodafone, Deutsche Telekom, Emirates Telecom, Telecom Italia, at & T and other top global operators have issued their own development plans and launched pilot projects.
  
In the vertical industry, more and more manufacturers begin to use nb-iot technology to enhance their competitiveness. For example, intelligent trolley case with intelligent tracking, over distance alarm, electronic lock control, battery monitoring and other functions, and intelligent bicycle with position positioning and anti-theft function, information upload and tracking function has been introduced by manufacturers. In addition, the deployment of nb-iot is also increasing in the fields of municipal street lamp and garbage management, environmental monitoring and livestock breeding irrigation
  
8. Profit making in telecommunication industry
  
It seems that telecom operators have found a new growth point. Nbiot, a global broadband technology forum, was held in April 2015. NB IOT is the latest technology proposed by mainstream telecom operators and equipment manufacturers in 3GPP, the global standards organization, for the Internet of things market.
  
The telecom industry has been looking forward to the Internet of things market for 10 years. However, traditional 2G, 3G and 4G networks do not meet the requirements of low power consumption and low cost of Internet of things devices. Most of the Internet of things devices mainly use free technologies such as Wi Fi and Bluetooth when connecting, which makes it difficult for operators to make profits. At present, there are only about 40 million Internet of things terminal operators in the Internet of things market, accounting for about 60% of the global Internet of things market.
  
However, the Nb IOT proposed for the Internet of things may bring three times of increment to operators. According to Hu houkun, Huawei's rotating CEO, Nb IOT will enable the number of IOT terminals to reach 1 billion by 2020. Perhaps for this reason, Nb IOT has been called "a commercial blue ocean with great potential" by Luke ibbeston, Vodafone's director.
  
Telecom companies bet on Internet of things
  
Before the number of 7.1 billion mobile users in the world, 230 million Internet of things connections do not account for much proportion, but mobile users have been saturated, and the Internet of things is just starting, so this is one of the few services worthy of expectation in the telecom industry.
  
At present, most telecom operators encounter the problem of stagnant growth. According to the data, of the 18 telecom operators listed in the Fortune 500 in 2015, 7 of them experienced a decline in revenue. The revenue of Spain Telecom, the world's ninth largest operator, dropped as much as 11%.
  
The saturation of mobile communication market is the main dilemma for operators. In the latest financial report of Vodafone, in the 2015 fiscal year (from March 2014 to March 2015), Vodafone's mobile business revenue accounted for 71% decreased, and the number of users increased by only 3%. In contrast, Vodafone's revenue from the Internet of things business increased by 24.7% year-on-year, and the number of Internet of things connections also increased from 16.1 million in fiscal year 2014 to 21.5 million, an increase of 33.5%.
  
According to Vodafone's financial report, each mobile user can contribute $105 in annual revenue to Vodafone, while each Internet of things connection contributes $27.8 per year. However, providing network services for mobile users requires huge network construction costs and maintenance costs. Almost all Internet of things services are provided on the basis of the existing network, and the cost is extremely low, 27.8 US dollars, most of which are profits.
  
At present, Vodafone's Internet of things services are distributed in 27 countries, but most of them are still deployed on traditional mobile networks. The growth rate of Vodafone's Internet of things services is restricted by power consumption, connection limit and cost. In May 2014, Vodafone and Huawei proposed nbm2m technology, trying to provide low-cost, low-power IOT connectivity by improving the existing network. Nbm2m is also the predecessor of Nb IOT. In September this year, the international organization for standards (3GPP) passed the project decision of "NB IOT" in Phoenix, USA. according to the plan, Nb IOT standard will be frozen in 3gppr13 in March 2016, and then the scale commercial application of Nb IOT will start soon.
  
According to the statistics of Machina research, a global Internet of things research organization, in 2015, the number of Internet of things connections of global operators was 230 million, which contributed about 7 billion dollars to the market of operators. This number will reach 24 billion dollars in 2020. According to a Huawei staff member, by 2020, the proportion of IOT devices connected to the operator's network may reach 20%, and the proportion will continue to increase, and the proportion of Wi Fi and Bluetooth Based connections will decrease.
  
Giant alliance or end "fragmentation"
  
"Compared with Wi Fi, Bluetooth and other technologies, Nb IOT's most obvious advantages are data collection and energy consumption." In the exhibition area of MBB, Luo Yanhong, chief of science and technology products section of Shenzhen Dahang, told reporters of the 21st century economic report.
  
"The data collected by Wi Fi, Bluetooth and other technologies are transmitted to the user's mobile phone, so it is difficult to form big data. Moreover, the data accuracy rate is very low and the power consumption is very high, so it needs to be charged once every two days. After the Nb IOT connection, the data collection is directly uploaded to the cloud, which is very accurate, and can realize 5-year non charging." According to Luo Yanhong, Dahang technology plans to use NB IOT technology in 500000 bicycles.
  
Based on these characteristics, a large number of wearable devices, intelligent doors, windows and thermometers are the market of Nb IOT. The huge market not only attracts telecom players, but also a number of chip and sensor giants such as Qualcomm and Intel have joined the Nb IOT camp, and their market far exceeds that of telecom operators.
  
According to Huawei, a number of chip companies such as Qualcomm, quectel and Swiss enterprise ublox are Huawei's partners in NB IOT technology. In addition, Huawei's multiple product lines have also launched joint research and development of the Internet of things. Neul bought Huawei chips in the UK for $25 million last year. At present, the company has launched NB IOT chip. Previously, Huawei also launched the liteos operating system for the Internet of things.
  
In July this year, Intel, a giant dedicated to Internet of things chips, also joined the Nb IOT camp. In the same month, Intel, Ericsson and Nokia announced their commitment to the next generation of wireless connectivity for IOT. Before 3GPP officially named NB IOT, nb-lte was also one of the technical precursors. Intel announced at the time that it would provide a roadmap for the nb-lte chipset, with products available in 2016. It is worth mentioning that Ericsson was the first telecom enterprise to lay out the Internet of things. As early as 2010, Ericsson put forward the concept of "50 billion connection", which has been cited by a large number of enterprises and research institutions.
  
Before NB IOT, the Internet of things industry had different paths in terms of terminals, networks, chips, operating systems and platforms, which made the Internet of things "fragmented" seriously. NB IOT's giant alliance may become an opportunity to end fragmentation and unify the Internet of things.

3. Promote the application of nb-iot in vertical market and incubate new business opportunities;
  
4. Cooperate with all industrial partners of nb-iot to ensure the interconnection of solutions and services of different manufacturers.
  
At the meeting, China Mobile, Emirates Telecom, LG uplus, Shanghai Unicom, Telecom Italia and Vodafone (ranked in English letters) jointly announced the establishment of six nb-iot open laboratories worldwide. The lab will focus on nb-iot's business innovation, industrial development, interoperability testing and product qualification verification. At the same time, as a key component of nb-iot forum, the open laboratory will also be committed to exploring new business cases and business models, and sharing the results to the whole industry.
  
It is reported that some customers have already started to test the pre nb-iot, and it is expected to be ready for commercial use in the second half of 2016. Commercial deployment is expected in early 2017.
  
The preparation of nb-iot forum and the establishment of open laboratory indicate that nb-iot industry has entered a new stage of development, which will strongly promote the rapid maturity and commercial process of the industry. The forum will be under the management and guidance of existing international organizations. Its scope, form and objectives have begun to be developed, and its members can be updated in the future.

ZTE becomes a major member of Nb IOT Forum
  
Recently, ZTE announced that ZTE officially joined and became a major member of GSMA NB IOT (narrow band IOT) forum at the just concluded MWC 2016 exhibition in Barcelona. NB IOT alliance covers the global mainstream operators, major equipment manufacturers, chip suppliers, terminal module manufacturers, etc. As a major equipment manufacturer, ZTE will work with other partners in the alliance to jointly promote the development of Nb IOT industry based on cellular network; assist the alliance to promote and verify NB IOT technology, participate in and promote the development of innovative services and applications related to NB IOT, and promote the commercial use of Nb IOT. [19]
  
ZTE has been the main promoter of Nb IOT, a wide area low-power technology for the Internet of things. IOT (Internet of thing) is oriented to massive connection. In some scenarios of Internet of things, such as intelligent meter reading, ecological agriculture, intelligent parking, intelligent community, intelligent building and other scenarios, the demand for wide coverage, low power consumption and low-cost terminals is more clear. Currently, 2G / 3G / 4G, WLAN and other wireless technologies are unable to meet these challenges. However, Nb IOT, the narrow-band IOT technology based on LTE, has the characteristics of low power consumption, wide coverage and multi connection, which can meet the needs of IOT scenarios. The ISO 3GPP plans to freeze and release NB IOT standards in June 2016. As one of the main contributors of Nb IOT standard, ZTE has actively promoted and invested a lot in the research and standardization of Nb IOT technology, and has made major contributions to core air interface technologies such as channel design, short code, multi connection and ultra-low power consumption.
  
With the development of intelligent, mobile and cloud technologies, various forms of intelligent terminals are becoming more and more popular. According to the forecast, the number of smart connections in the world will reach 100 billion by 2020. NB IOT will effectively solve the demand of 100 billion connections for operators' networks, and enable telecom operators to quickly meet the connection requirements of "matter to matter" interconnection, which is an important direction for the development of telecom operators. ZTE has created an end-to-end solution based on Nb IOT for operators and industries, and has actively invested in the research on chips, terminals, systems and IOT platforms, so as to help operators realize "100 billion" connectivity in the future.
  
ZTE put forward the m-ict strategy of Internet of things in 2015, providing the overall solution of IOT; it has perfect solutions and applications in industrial Internet, Internet of vehicles, smart home and smart city, intelligent meter reading and other fields. By optimizing the connection, ZTE builds an open IOT application enabling platform, and introduces smartos suitable for the Internet of things. ZTE is committed to building a safe and credible ecological environment, providing services for customers in the upstream and downstream industrial chain, and helping partners to tap the value of each "bit". ZTE will continue to work with its partners to provide leading IOT end-to-end solutions and services for industry, government enterprises and operators.
  
10 nb-iot new IOT trial commercial
  
On May 17, 2017, China Telecom announced the completion of the world's first commercial next generation Internet of things (nb-iot) network with the widest coverage, and the leading 4G network achieved nationwide coverage.
 
  
On June 5, 2017, China Telecom Group Corporation and Qingdao Municipal People's government signed the strategic cooperation agreement and officially launched the new generation of Internet of things (NB IOT). China Telecom will give full play to the advantages of the Internet of things private network channel, mainly with 4G / 5G mobile network, take the lead in promoting the construction of Nb IOT in Qingdao, and promote Qingdao to become the leading demonstration city and smart city benchmark of the Internet of things in China.
  
In November 2016, China Telecom listed Wuxi as the first batch of narrowband IOT pilot cities. Wuxi Branch of China Telecom adopts the most advanced network communication equipment and architecture in the industry, with an investment of nearly 200 million yuan and construction of nearly 2000 communication base stations in five months. It is the first to realize seamless global coverage based on 800m ultra-low frequency narrow-band network.
  
China Unicom will hold the "China Unicom NB IOT network trial business launch conference and Internet of things ecological forum" on May 15, 2017 to meet the Internet of things and seize the 10 billion level market opportunity. As an active participant in the construction of smart city, China Unicom has been committed to the development of the Internet of things, and has built the world's largest NB IOT commercial metropolitan area network, represented by Shanghai, and realized the full coverage of Shanghai metropolitan area.
  
Different from China Telecom's efforts to rebuild 800m and deploy NB IOT at 800m low frequency, China Unicom has adopted a 900m / 1800m dual frequency deployment. In addition to Beijing, Shanghai and other big cities, more than 80% of base stations plan to adopt LTE 1800m based upgrade deployment scheme.
  
At present, we are actively promoting NB IOT and EMTC technology pilot. The pilot project mainly includes two parts: one is the field experiment, relying on the open laboratory of China Unicom Internet of things, mainly promoting the docking of various kinds of Internet of things technology; the other part is the field test. China Unicom has promoted the testing work in more than 10 cities in China.
  
The three major domestic operators have actively deployed NB IOT test. As of October 2017, China Telecom has built 310000 base stations and completed the deployment of Nb IOT network; China Mobile plans to build 145000 base stations in 2017; China Unicom plans to carry out pilot application in five cities in 2017. In 2018, the construction of nb-iot network of the three major operators of China Mobile Unicom will be fully launched. It is planned to reduce the current GSM network base stations and gradually transform them into nb-iot network base stations
