As a new type of mobile communication network, 5G must not only solve human-to-human communication, but also provide users with a more immersive and extreme service experience such as augmented reality, virtual reality, and ultra-high-definition (3D) video. The problem of communication between things and things meets the needs of Internet of Things applications such as mobile medical, car networking, smart home, industrial control, and environmental monitoring. In the end, 5G wifi router will penetrate into various industries and fields of the economy and society, and become a key new infrastructure supporting the digital, networked, and intelligent transformation of the economy and society.

Performance

1. The peak rate needs to reach 10-20 Gbit/s to meet high-definition video, virtual reality and other large data transmissions.

2. The air interface delay is as low as 1ms, which meets real-time applications such as autonomous driving and telemedicine.

3. Equipped with a million connections/square kilometer device connection capability to meet IoT communication.

4. The spectrum efficiency is more than 3 times higher than that of LTE.

5. With continuous wide area coverage and high mobility, the user experience rate reaches 100Mbit/s.

6. The flow density reaches more than 10Mbps/m2.

7. Mobility Supports high-speed movement of 500km/h.

Network slicing is used to meet the differentiated needs of 5G. Network slicing refers to a logically independent network customized by selecting specific features and functions from a network, which allows operators to deploy multiple features and services with different features. Logical networks serve their respective target users. Currently, three types of network slicing are defined, namely, enhanced mobile broadband, low latency and high reliability, and large-connected Internet of Things.
