Fourth Generation Long Term Evolution connectivity is a high-speed wireless communication standard developed to provide users with up to 10 times the speed of third generation networks. It is developed by the 3rd Generation Partnership Project and is one among several competing 4G standards, such as WiMax and Ultra Mobile Broadband.
While several technologies bear the 4G tag, LTE is set to be the first worldwide mobile phone standard and can, in theory, work at a minimum speed of 100 megabits per second and a maximum of 50 megabytes per second as of 2015. Practically, the connection strength of a 4G LTE network determines its actual speed and depends on mobile network frequency bands, location and the service provider.
4G LTE uses orthogonal frequency division multiplexing, a transmission technology that reduces the time taken to buffer and load Web pages. OFDM minimizes interference and pushes larger amounts of data into a single slice of radio bandwidth for quick streaming. It is primarily a packet switched or data network and uses the same standards and protocols as the Internet for Internet Protocol-based voice calls, data and multimedia streaming. 4G LTE covers a range of frequency bands that varies based on service provider allocation, and it is an all-IP flat architecture standard.
