5G is coming The background of 5G

The background of 5G The meaning of 5G 5G is the name of the current next generation mobile data connection. The fifth generation mobile communication technology is the latest generation of cellular mobile communication technology. The performance objectives of 5G are high data rate,reduced latency, energy saving,cost reduction,increased system capacity and large- scale device connectivity

The meaning of 5G • 5G is the name of the current next generation mobile data connection. • The fifth generation mobile communication technology is the latest generation of cellular mobile communication technology. • The performance objectives of 5G are high data rate, reduced latency, energy saving, cost reduction, increased system capacity and large￾scale device connectivity. The background of 5G

The background of 5G What will be the impact of 5G? First of all,the distance between base stations is shortened to 2300 meters,and the density of base stations per unit area is 100 times higher than that of 4G. Secondly,any effort to integrate all kinds of networks is to follow the trend,and any attempt to build an independent,purely based on wireless technology is to move against the current. Thirdly,the extremely fast Internet speed can stimulate the development of many applications that need high-speed Internet

5G network architecture 5G network architecture design includes system design and network design. System design focuses on the realization of logical functions and the information interaction process between different functions. Networking design focuses on the implementation scheme of equipment platform and network deployment
