Nortel Pushes MIMO

OTTAWA -- Nortel(*) (NYSE/TSX: NT) has conducted the industry's first wireless transmission using Uplink Collaborative MIMO to demonstrate the ability for operators to serve up to double the number of mobile broadband subscribers supported in a cell site as current wireless technologies allow.

For 4G wireless operators, this enables the potential to substantially increase their subscription revenue with the same capital investment. Developed by Nortel, Collaborative MIMO is part of the WiMAX industry standard and is also being proposed for 3GPP WCDMA Long-Term Evolution (LTE) and 3GPP2 CDMA EV-DO Rev-C standards.

"Uplink Collaborative MIMO creates a technological disruption that offers revolutionary improvement in wireless network capacity and provides a clear path to 4G Mobile Broadband - of which WiMAX is the first technology," said John Hoadley, chief technology officer, Mobility and Converged Core Networks, Nortel.
