The fourth generation mobile phone mobile communication standard refers to the fourth generation mobile communication technology, the foreign language abbreviation: 4G. The technology includes TD-LTE and FDD-LTE (Strictly speaking, LTE is only 3.9G, although it is promoted as 4G wireless standard, it is not recognized by 3GPP as the next generation wireless described by the International Telecommunication Union. The communication standard IMT-Advanced, in the strict sense, has not yet reached the 4G standard. Only the upgraded version of LTE Advanced meets the requirements of the International Telecommunications Union for 4G).
4G is a combination of 3G and WLAN, and can quickly transfer data, high-quality audio, video and images. 4G can download at speeds of more than 100 Mbps, 25 times faster than home broadband ADSL (4 megabytes), and can meet the requirements of almost all users 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 superiority.http://www.ietross.com/
