What are the characteristics of 5g network communication?

Like the early 2G, 3G and 4G mobile networks, 5g mobile networks are digital cellular networks in which the service areas covered by suppliers are divided into many small geographic areas called cellular networks. Analog signals representing sound and image are digitized in mobile phones, converted by analog-to-digital converters and transmitted as bit streams. All 5g wireless devices in the cell communicate with the local antenna array and low-power automatic transceivers (transmitters and receivers) in the cell via radio waves. The transceiver allocates channels from the common frequency pool, which can be reused in geographically separated cells. The local antenna is connected to the telephone network and the Internet via a high bandwidth optical fiber or wireless backhaul connection. As with existing mobile phones, when users cross from one cell to another, their mobile devices automatically "switch" to the antennas in the new cell.

The main advantages of 5g network are The data transmission rate is much higher than the previous cellular network, up to 10Gbit / s, faster than the current wired internet and 100 times faster than the previous 4G LTE cellular network. Another advantage of 4g-30ms is faster response time than 4g-1ms. Because of faster data transmission, 5g network will not only provide services for mobile phones, but also become a general home and office network provider, competing with cable network providers. Previous cellular networks provided low data rate Internet access for mobile phones, but a cell phone tower could not provide enough bandwidth economically as a general Internet provider for home computers.
 
5g network communication features:
 
1. The peak rate needs to reach the Gbit / s standard to meet the high-definition video, virtual reality and other large data transmission.
2. The air interface delay level needs to be about 1ms, which can meet the real-time applications such as autopilot and telemedicine.
3. Super large network capacity, providing the connectivity of 100 billion devices to meet the Internet of things communication.
4. The spectrum efficiency is 10 times higher than LTE.
5. Under continuous wide area coverage and high mobility, the user experience rate reaches 100mbit / s.
6. The flow density and connection number density are greatly improved.
7. The system is collaborative and intelligent, which is characterized by multi-user, multi-point, multi antenna and multi ingestion cooperative networking, and flexible automatic adjustment between networks.

The above is the key difference between 5g and previous generations of mobile communication, which is the result of mobile communication from technology-centered to user-centered.
