What's the difference between 5g and 6G networks?

What's the difference between 5g and 6G networks?

The peak theoretical transmission speed can reach tens of GB per second, which is hundreds of times faster than the transmission speed of 4G network. The whole ultra-high image quality movie can be downloaded in one second. The main goal of 5g network is to keep the end users connected. 5g network will support not only smart phones, but also smart watches, fitness wristbands and smart home devices such as bird's nest indoor thermostat. 5g network will be the real upgrade of 4G network, and its basic requirements are different from today's wireless network.


Extension of 6G and 6G wireless network


6G network is an extension of 5g network. The theoretical download speed can reach 1TB / s. It is expected to start research and development in 2020 and put into commercial use in 2030. 6G is based on 5g integrated satellite network to achieve global coverage. 6G is a cheap and ultra fast Internet technology, which can provide incredible high data rate or extremely fast Internet speed up to 11gbps for wireless or mobile terminals. The satellite communication network composed of 6G system can be telecommunication satellite network, earth remote sensing imaging satellite network and navigation satellite network. 6G system integrates these satellite networks to provide 6G users with network positioning and identification, multimedia and Internet access, weather information and other services.


So, what is the difference between China Mobile, China Unicom and China Telecom's 1g, 2G, 3G, 4G, 5g and 6G networks?


First of all, the Internet speed is different


In general, the highest GPRS access rate of 2G network is about 30K; in general, the highest GPRS access rate of 3G network is about 700k; in theory, the peak uplink and downlink rate of 4G network can reach 100Mbps (100Mbps). 5g network peak theoretical transmission speed can reach 10Gb / S; 6G network speed can reach 11gbps; Internet speed, 6G > 5g > 4G > 3G > 2G.


Secondly, the coverage rate is different


The coverage rate of 2G is much higher than that of 3G, especially in mountainous areas. The coverage rate of 4G is gradually improving, and 5g and 6G have not been officially commercialized.


Secondly, the fees are different


4G is the most expensive, 2G is the cheapest.


Finally, the power and utilization are different


3G network has less power and radiation than 2G network, and 4G network has less radiation after detection. 4G is more efficient than 3G in network utilization, and it will also save unit power consumption.


Of course, 5g and 6G are not yet commercially available, but they are definitely good. Let's wait and see!
