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.
