What is LTE? LTE Stands for Long Term Evolution. LTE is a 4G wireless broadband. LTE network is designed to provide up to 10x the speeds of 3G networks. LTE is developed by the Third Generation Partnership Project (3GPP). LTE helps to improve speed of 3G networks for mobile devices such as smartphones, tablets, netbooks, notebooks and wireless hotspots. LTE Speed acts as a standard for wireless communication for data terminals and mobile phones to support high speed data. LTE projects is purely based on EDGE/GSM and HSPA/UMTS or mobile network technologies. An acronym for 3rd generation partnership project is 3GPP. it operates and carries out its function under European Telecommunications standard Institute. LTE projects are a natural upgrade way for carries with both GSM/UMTS networks and CDMA 2000 networks. It is also known as LTE super 3G known LTE Super 4G.
Scalable Bandwidth support in Long Term Evolution (LTE Projects).
Time Division Duplex (TDD): TDD requires less hardware cost and uses more bandwidth for uploading and downloading.
It receives and transmits on same bandwidth in alternate way. On same bandwidth transmission and reception takes place with a time gap.
Frequency Division Duplex (FDD): FDD splits bandwidth to transmit uplink and downlink by a guard band in between. It allows way to better reception and less interference.
LTE Architecture Functions.
LTE projects use carrier aggregation to increase bandwidth and bit rate. From a network operator carrier aggregation is feature of high demand. Major design challenge is on the terminal side.Higher bandwidths are supported and carrier aggregations in different frequency bands are:
- Wide band power amplifier.
- Increase complexity of transceiver circuits.
- Tunable antenna.
- Highly efficient switches.
MIMO refers to multiple inputs Multiple Output. The performance of the system can be improved. This technology provides LTE with data throughput improvement and obtaining spectral efficiency by use of OFDM.
Seven Modes of MIMO in LTE.
- Multi user MIMO.
- Beam Forming.
- Single Antenna.
- Open Loop Spatial multiplexing.
- Transmit delivery.
- Close Loop spatial Multiplexing.
- Closed loop with pre coding.
Low power eNodeBS which provides enhanced coverage and capacity at cell edges are Relay nodes. LTE Coverage in specified areas at low cost can be provided by Relay nodes.LTE relay Nodes are of 2 types
- Out band.
- In Band.
A huge range of techniques that supports dynamic transmission or reception or coordination with multiple geographically separated eNBs is coordinated multipoint transmission and reception.
