LTE (acronym for 'Long Term Evolution') is a wireless broadband technology which is basically designed for wireless communication of high-speed data for mobile phones and data terminals. It is commonly marketed as 4G LTE.
LTE is significantly improved over its predecessor UMTS 3G technology which is based upon WCDMA, HSPA (HSDPA and HSUPA combined) and HSPA Evolution (HSPA+). LTE allows operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth. Even though HSPA and its evolution are strongly positioned to be the dominant mobile data technology for the next decade, the 3GPP family of standards must evolve toward the future. HSPA+ will provide the stepping-stone to LTE for many operators.
LTE capabilities include:
- Increased spectral efficiency over Release 6 HSPA by two to four times
- Scalable bandwidth up to 20 MHz, covering 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz in the study phase
- Reduced latency, up to 10 milliseconds (ms) round-trip times between user equipment and the base station, and to less than 100 ms transition times from inactive to active
- Operation in both TDD and FDD modes
- Downlink peak data rates up to 326 Mbps with 20 MHz bandwidth
- Uplink peak data rates up to 86.4 Mbps with 20 MHz bandwidth
Global Market of LTE:-
The global LTE market is expected to grow from $2.28 billion in 2010 to $262.05 billion in 2015. This represents a CAGR of 158.2% from 2010 to 2015. Saturation in the existing 3G networks, the quest for higher data rates and the need for spectral efficiency have been prominent factors, triggering the demand for global LTE deployments.
North America is the fastest growing market in terms of LTE infrastructure setup; whereas EMEA faces certain government-related issues with regards to spectrum auctions. Asia-Pacific, Japan, and Latin America are the fastest growing regions.
The LTE market has wide scope in terms of operability as it is capable of operating in both TDD and the FDD modes, thereby giving flexibility to the operators. With innovations such as network sharing and hybrid networks budding in the market of late, LTE players have immense opportunity which still remains untapped.
