Extended explanation:

1 and 4G integrate 3G and WLAN, which can transmit data, high quality, audio, video and images quickly.

The download speed of 2.4G can reach more than 100Mbps, which is 25 times faster than the current home broadband ADSL(4 megabytes), and can meet the requirements of almost all users for wireless services.

3. You can deploy 4G in places that DSL and cable TV modems can't cover, and then expand to the whole area. Obviously, 4G has incomparable advantages.

4. With the development of data communication and multimedia services, the fourth generation mobile communication has appeared to meet the needs of mobile data, mobile computing and mobile multimedia services, so it is reasonable to expect that this fourth generation mobile communication technology will bring people a better future.

Because of its high data transmission speed, 5.4G is praised as a well-deserved "high-speed dialogue" between machines by the China Internet of Things School-Enterprise Alliance.
