The average downlink rate of a 5G network reaches 1.4Gbps, realizing a nearly 20-fold gain compared to the 71Mbps average rate of a 4G network, while the average latency drops from 115 milliseconds to 4.9 milliseconds, for a nearly 23-fold response speed-up.
Due to the introduction of high spectrum resources and the support of massive MIMO technology, the capacity of 5G networks will be increased by tens of times compared to today, which means that the base station can provide services to more terminals at the same time. In signal-heavy areas with extremely high user density, even if tens of thousands of people are concentrating on communication, 5G can satisfy everyone's need for high-speed internet, and there won't be a situation where there's a signal but you can't get on the internet.

Note:
With the advent of the 5G communication era as well as the gradual maturation of cell phone wireless charging technology. To the cell phone hardware material also do as a choice of factors, due to the metal back cover on the more signal shielding strong, in addition to the metal back cover is difficult to make the phone to realize the function of wireless charging. Therefore, 2.5D/3D glass was born, glass cover from 2.5D to 3D, from the front cover to the back cover, the application volume is growing steadily.
While 3D glass is already the standard for 5G cell phones, the glass hot bending process exists in the four major problems of hot bending, grinding and polishing, 3D surface printing, and post-polishing cleaning, and whether it is standardized in the production process, the yield rate is also the key to whether it can be strong in the industry.
