LTE targets requirements of next generation networks including downlink peak rates of at least
100Mbit/s, uplink rates of 50 Mbit/s and RAN (Radio Access Network) round-trip times of less than 10ms.LTE supports flexible carrier bandwidths, from 1.4MHz up to 20MHz as well as both FDD (Frequency Division Duplex) and TDD (Time Division Duplex).
LTE further aspires to improve considerably spectral efficiency, lowering costs, improving services,making use of new spectrum and refarmed spectrum opportunities, and better integration with other open standards. The resulting architecture is referred to as EPS (Evolved Packet System) and comprises the E-UTRAN (Evolved UTRAN) on the access side and EPC (Evolved Packet Core) via the System Architecture Evolution concept (SAE), on the core network side.
LTE advantages include high throughput, low latency, plug and play from day one, FDD and TDD
in the same platform, superior end-user experience and simple architecture resulting in low operating
expenditures (OPEX). LTE will also support seamless connection to existing networks, such as
GSM, CDMA and WCDMA. However LTE requires a completely new RAN and core network deployment and is not backward compatible with existing UMTS systems.
