Mobile networks are changing the way people communicate and access information. Network access at anytime and anywhere is transforming the telecom industry. In the near future, wireless network access will eventually prevail. 5G technology will enable flexible, reliable, and secure wireless networks to connect people with all applications, services, and things, thus leading human race into the era of "Everything on Mobile".

In the "Everything on Mobile" era, mobile networks must meet requirements more diverse than ever. These requirements can be identified from three dimensions: number of connections, latency, and throughput. These three dimensions together will bring unprecedented challenges to future 5G networks:

1. Number of connections. Although a 4G network provides thousands of connections for each cell, a 4G network cannot meet the connection needs of Everything on Mobile. A 5G network provides up to a million connections per square kilometer. This will bring an exponential increase in the number of connections.

2. Latency. The latency on a 4G network, 50 ms, is half of that of a 3G network, . However, applications such as self-driving cars still require much lower latency than a 4G network.

3. Throughput. A higher throughput will better meet consumer needs. The throughput of a 4G network is 10 times higher than that of a 3G network, but once 4K video services become popular, the 4G network cannot meet the new throughput demands.

To meet the preceding requirements, 5G should have the following performance advantages over existing mobile communication technologies:

• 100 billion connections

• 1 ms latency

• 10 Gbps throughput
Based on the features of 5G networks and the development trend for Internet of Things, Huawei has identified some typical application scenarios during the process of 5G innovation
