LTE (Long Tearm Evolution) is a standard for wireless communication of high-speed data. It is the next generation of the old GSM and UMTS/HSPA network technologies. The goal of LTE is to increase the capacity and speed of wireless data networks utilizing cutting-edge hardware and techniques that have recently been developed. Its wireless interface is incompatible with 2G (GSM) and 3G(UMTS) networks, meaning it must be operated on a separate spectrum.
Features of LTE include an all-IP flat network architecture, end-to-end QoS (quality of service) including provisions for low-latency communications. It is planned that peak download rates will achieve 300 Mbps and upload rates 75 Mbps.
