4G

4G (or 4-G) is short for fourth-generation wireless telephone technology. The primary aim of 4G seems to be very high data transmission speed, of the same order of magnitude as a local area network connection (10 Mbits/s and up).

An amorphous and presently entirely hypothetical concept, the term has variously been applied to wireless LAN technologies like Wi-Fi, as well as other potential successors of the current 3G mobile telephone standards. 4G can also be qualified by the use of smart-radio technology to efficiently manage spectrum use and transmission power as well as the use of mesh routing protocols to create a pervasive network.
