LTE(Long Term Evolution) is a 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. LTE is evolved from the GSM/EDGE and UMTS/HSPA network technologies.
It has increased the capacity and speed using DSP (Digital Signal Processing) techniques. The standard is developed by the 3GPP (3rd Generation Partnership Project).
LTE service was first launched on December 14, 2009 by TeliaSonera in Stockholm and Oslo.
DU and Etisalat has launched the LTE service in UAE on a Network which is capable of speed of 100-150 mbps.
The advancements achieved in LTE includes:
- Downlink rate of 300 Mbits/s and uplink rate of 75 Mbits/s as compared to 3G which provides max speed up to 42 Mbits/s.
- Latency is less than 5 ms.
- It supports carrier from 1.4 MHz to 20 MHz.
- It provides downlink rate of 300 Mbits/s and uplink rate of 75 Mbits/s.
- Excellent support for mobility which supports moving terminals at up to 350 km/h.
- LTE supports both FDD (Frequency Division Duplexing) and TDD (Time Division Duplexing).
- LTE’s simplified Architecture, Spectrum flexibility and support for interoperation with legacy standards are key features.
- LTE’s another feature like MBSFN (Multicast-Broadcast Single Frequency Network) provides Mobile TV services using LTE infrastructure.
The support for Voice in LTE is being reengineered and different approaches are being adopted e.g. Voice over LTE, Circuit-Switched fall back and Simultaneous voice and LTE.
