In fact, 4G signal refers to the fourth generation of mobile communication technology, foreign language abbreviation: 4G. The technology is available in td-lte and fdd-lte (technically, LTE is only 3.9g, and despite being touted as the 4G wireless standard, it is not yet technically recognized by 3GPP as imt-advanced, the next generation wireless communication standard described by the international telecommunication union (itu). Only an upgraded version of LTE Advanced will meet the itu’s 4G requirements.
4G is a combination of 3G and WLAN, and can quickly transfer data, high quality, audio, video and image. 4G can be downloaded at speeds of more than 100Mbps, 25 times faster than home broadband ADSL (4mb), and can meet almost all users’ requirements for wireless services. In addition, 4G can be deployed where DSL and cable modems are not covered, and then extended to the entire region. Obviously, 4G has incomparable advantages.
