Key technologies of 5G
1 and key technologies of 5G wireless.
5G international technical standards focus on meeting the flexible and diverse needs of the Internet of Things. Based on the basic technologies of OFDMA and MIMO, 5G has adopted a flexible new system design to support three major application scenarios. In terms of frequency band, unlike 4G's support for medium and low frequencies, considering the limited resources of medium and low frequencies, 5G supports both medium and low frequencies, in which the medium and low frequencies meet the requirements of coverage and capacity, and the high frequencies meet the requirements of capacity improvement in hot spots. 5G has designed a unified mid-low frequency and high frequency technical scheme, which supports the basic bandwidth of 100 MHz.
Key Technologies of 2.5G Network
5G adopts a new service architecture to support flexible deployment and differentiated business scenarios. 5G adopts full-service design, modularizes network functions, supports on-demand calls, and realizes functional reconfiguration; Service-oriented description is easy to realize open capability, which is conducive to introducing IT development power and exerting network potential.
5G supports flexible deployment. Based on NFV/SDN, hardware and software are decoupled, and control and forwarding are separated. Using the cloud networking of general data center, the network function deployment is flexible and the resource scheduling is efficient; Support edge computing, cloud computing platform sinks to the edge of the network, and support flexible gateway selection and edge streaming based on applications.
