The LTE standard

The LTE standard includes:

Peak download rates of 326.4 Mbit/s for 4x4 antennas, 172.8 Mbit/s for 2x2 antennas for every 20 MHz of spectrum.

Peak upload rates of 86.4 Mbit/s for every 20 MHz of spectrum.

5 different terminal classes ranging from a voice centric class up to a high end terminal that supports the peak data rates. All terminals will be able to process 20 MHz bandwidth.

At least 200 active users in every 5 MHz cell.

(i.e., 200 active data clients)

Sub-5ms latency for small IP packets.

Increased spectrum flexibility, with spectrum

slices as small as 1 .5 MHz .and as large as 20 MHz. W-CDMA requires 5 MHz slices, leading to some problems with roll-outs in countries where the 5 MHz spectrum is
already allocated to 2 - 2.5G legacy GSM and cdmaOne. The 5 MHz chunks also limit
the amount of bandwidth per handset.

■ Optimal cell size of 5 km, 30 km sizes with reasonable performance, and up to 100 km cell sizes supported with acceptable performance.

■ Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and should coverage be unavailable, continue the operation without any action on their part
using GSM/GPRS or W-C DMA-based UMTS or even 3GPP2 networks such as cdmaOne
orCDMA2000) .

■ Support for MBSFN (Multicast Broadcast Single Frequency Network). This feature can
deliver services such as MBMS using the LTE infrastructure, and is a competitor to DVB-h.

A large amount of the work is aimed at simplifying the architecture of the system, as it evolves from the existing hybrid (packet and circuit switching) network,
to an all-IP flat architecture system.

Advantages of LONG TERM EVOLUTION or LTE

Advantages of LONG TERM EVOLUTION or LTE

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.

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.
