cellular backup internet connection

What is cellular backup internet connection? We all know cell phone communication, in fact, it uses cellular mobile communication to transmit data.

5G has become the most talked-about topic among the people. Whether it is government, enterprises or ordinary people, they are always paying attention to the development of 5G. "High bandwidth, fast download, big data, interconnection of everything", everyone knows that 5G is coming from us. The closer, but how close is it?

Speaking of 5g, we must first talk about 4g. The key technology of 4g is multiple input and output (MIMO), which refers to the technology of spatial diversity using multiple transmission and multiple receiving antennas. It uses discrete multiple antennas, which can effectively communicate The link is decomposed into many parallel sub-information, thereby greatly increasing the capacity. MIMO system can improve the system's anti-fading and noise performance, so as to obtain huge capacity. MIMO technology is a spatial diversity technology that achieves high data rates, increases system capacity, and improves transmission quality.

5th generation mobile communication technology features

5G is the only network for business applications and user experience: it is a network with multiple services and multiple technologies.

5G business requirements:

1. Cloud Business

 The 5G end-to-end delay is required to be less than 5ms and the data rate to be greater than 1Gbps.

2. Virtual reality (VR)

The network speed must be above 300Mbps, the end-to-end delay is less than 5ms, and the mobile cell throughput is greater than 10Gbps.

3. HD video

4K video will become the standard business of 5G.

4. Internet of Things

The massive data connection brought by M2M/IOT requires 5G to have sufficient support capabilities. M2M requires the network delay to be reduced to 1ms.

5G technology includes 7 indicators: peak rate, delay, simultaneous number, mobility, cell spectrum efficiency, cell edge throughput, Bit cost efficiency

There are already 5g routers to improve services for the majority of M2M/IOT, such as H900q and H900s of E-Lins Technology Co., Ltd. have been put into use.
