LTE (Long Term Evolution) or 3G Long Term Evolution is the evolution of mobile cellular communications technology towards a full edge to edge broadband ip network, and is introduced in 3rd Generation Partnership Project (3GPP) Release 8.

The aim of this 3GPP project is to further develop the Universal Mobile Telecommunications System (UMTS) standard and provide an enhanced user experience and simplified technology for next generation mobile broadband. Scientists and design engineers from more than 60 operators, vendors and research institutes have teamed up to realise this radio access standardization effort.

Much of the 3GPP Release 8 standard will be oriented towards upgrading UMTS to 4G mobile communications technology, and an all-IP flat architecture system.

LTE target requirements

LTE targets requirements of next generation
networks including downlink peak rates of at least
1 0OMbit/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.
