LTE, Long-Term Evolution otherwise known as E-UTRAN (Evolved Universal Terrestrial Access Network), is a wireless communication standard first released by the 3rd Generation Partnership Project (3GPP) in 2008.

The motivation to upgrade the UMTS networks was sparked by the need to ensure the continuity of competitiveness of the 3G system for the future.

Furthermore, user demand for higher data rates and quality of service was also growing. There was a need to reduce complexity and at the same time avoid unnecessary fragmentation of technologies for paired and unpaired band operation.

LTE is essentially the access part of the evolved packet system (EPS). EPS is 3GPP’s LTE wireless communication standard to evolve network architecture and is purely IP based.

The main requirements for LTE are high spectral efficiency, high peak data rates, short round trip time as well as flexibility in frequency and bandwidth.
