Sri Lanka Telecom Mobitel announced today(06/05/2011) that it has carried out a successful trial of LTE (Long Term Evolution) Technology achieving speeds of up to 96 Mbps. At this LTE trial Mobitel has broken the speed barrier even further to demonstrate broadband speeds of up to 96Mbps in downlink and 49Mbps in uplink using LTE technology.
The Director General of Telecommunications(TRCSL) Mr.Anusha Palpita witnesses Mobitel demonstrating 4G(LTE) technology exceeding 96Mbps data download speed and 49Mbps in upload speed 1st in south Asia at Mobitel flagship center.
Reason to this speed in LTE
The prime factor behind thise super-fast speeds demonstrated in LTE technology when compared to existing and most advanced 3G technologies is that the spectral efficiency is 4 to 5 times greater in LTE than in the most advanced 3G technologies. The use of OFDM (Orthogonal Frequency Division Multiplexing) carrier modulation in LTE allows easy upward scalability for higher bandwidth requirements, coupled with MIMO technology, which effectively uses multiple antennae in both the Terminal Device (Data dongle, Tablet PC/Smart Phone etc.) and radio network to transmit and receive multiple streams of information within the same spectrum. The demonstration was carried out in the 2.6GHz frequency range, and initiatives are under way to explore operations at other spectrum bands for commercial deployment.
does it really work?
