Another high-speed wireless data milestone for Nortel
Nortel Demonstrates OFDM, MIMO at Super High Speeds
Technology to Improve Spectrum Efficiency, Enhance User Experience, Decrease Operator Costs
OTTAWA – Nortel* [NYSE/TSX: NT] has achieved another wireless technology milestone, demonstrating a significant increase in data throughput using beyond 3G (third generation) MIMO (multiple-input, multiple-output) and OFDM (orthogonal frequency division multiplexing).
The demonstration took place at Nortel’s Wireless Technology Lab in Ottawa. Nortel will highlight its 3G MIMO and OFDM success and recent learnings from its lab at CTIA Wireless 2005 in New Orleans (Ernest N. Morial Convention Center, Hall C, Booth #3125) March 14-16.
MIMO and OFDM will make it possible for wireless subscribers to download bandwidth-hungry applications – large file transfers, streaming video and mobile gaming – at speeds higher than today’s commercial 3G networks. Nortel has invested in advanced development of OFDM and MIMO for the past six years and has demonstrated the benefits and commercial feasibility of these technologies to more than 100 customers.
“Nortel is innovating beyond 3G to develop future wireless broadband technologies that will leverage existing service provider investments and enhance the subscriber experience through feature-rich services and multimedia applications,” said John Hoadley, vice president, Next Generation Wireless Access, Carrier Networks, Nortel. “We believe that OFDM and MIMO will be vital to service provider success and will be the foundation of future wireless broadband networks.”
OFDM and MIMO together can support up to two times more subscribers than OFDM alone. This will position service providers to make more efficient use of existing spectrum.
In Ottawa, Nortel demonstrated large information transfers with peak data rates at 37 Mbps over a standard 5MHz PCS mobility band, taking into account noise and fading conditions found on a real-world cellular network. The test network showed that with OFDM and MIMO, wireless subscribers can download a 128 MB file in approximately 30 seconds – four to 10 times faster than today’s 3G wireless networks.

Now I know there are people out there who think Nortel is just pumping out news on anything to bolster their image. But I know for a fact they have been drumming up lots of new business and have many large projects on the go or coming up world-wide.
Later.
