Long Term Evolution-LTE

Long Term Evolution (LTE) is thee project name of new air interface for wireless access being developed by the Third Generation Partnership Project (3GPP).The 3GPP generation system toward an all IP networks optimized for high speed data transmission.

these techniques are often loosely referred to as "MIMO" a term for multiple input multiple output antenna configuration and cosidered essensial for improving bustness and achieving goals for system capacity and single-user and headline peak data rates.

Long Term Evolution (LTE) is linked closely with the concurent System Architecture Evolution (SAE) project to define a simplified system architecture and Evolved Packet Core (EPC). These project provide a framework for increasing capacity, improving spectrum efficiency, improving cell-edge performance and reducing latency for real-time services such as video.

The aim to offer a 100 Mbps download and 50 Mbps upload rate for every 20 Mhz of spectrum. Support is intended for even higher rates,to 326.4 Mbps in the downlink using multiple antenna configurations. Rather than further developing current High Speed Packet Access (HSPA) and modulation schemes based on the Wideband Code Domain Multiple Access (W-CDMA) used in third generation UMTS cellular systems today.

Long Term Evolution (LTE) downlink and uplink transmission are based on new air interface specifically Orthogonal Frequency Division Multiplexing (OFDM) in the downlink and Single Carrier-Frequency Division Multiple Access (SC-FDMA) in the uplink.

The LTE specifications inherit all frequency bands defined for UMTS, which is a list that continues to grow. There are now 11 FDD bands covering frequencies from 824 to 2690 Mhz and 8 TDD bands covering 1900to 2620 Mhz.
