LTE, an evolution of UMTS (Universal Mobile Telecommunications System), is a 4G last-mile access technology for mobile communication. LTE is based on OFDMA (Orthogonal Frequency Division Multiple Access) in the downlink and SC-FDMA (Single Carrier-FDMA) in the uplink and efficiently supports MIMO (Multiple-Input Multiple-Output) antenna technology.

LTE is based on an All-IP network with Voice traffic supported as Voice over IP (VoIP) enabling better integration with other multimedia services.LTE will improve spectral efficiency, increase mobility, reduce the cost of data transport, and provide better integration with other open standards to enable co-existence with other 3GPP Radio Access Technologies (RATs).

Faster downloads, video sharing, and true Mobile TV with more channels are some examples of applications that will benefit from LTE’s greater performance.
