[{"type":"text","content":"\n\n\n\n\nOTTAWA, Oct. 24 /CNW/ - Nortel(x) (NYSE/TSX: NT) has conducted the\nindustry's first wireless transmission using Uplink Collaborative MIMO to\ndemonstrate the ability for operators to serve up to double the number of\nmobile broadband subscribers supported in a cell site as current wireless\ntechnologies allow.\nFor 4G wireless operators, this enables the potential to substantially\nincrease their subscription revenue with the same capital investment.\nDeveloped by Nortel, Collaborative MIMO is part of the WiMAX industry standard\nand is also being proposed for 3GPP WCDMA Long-Term Evolution (LTE) and 3GPP2\nCDMA EV-DO Rev-C standards.\n\"Uplink Collaborative MIMO creates a technological disruption that offers\nrevolutionary improvement in wireless network capacity and provides a clear\npath to 4G Mobile Broadband - of which WiMAX is the first technology,\" said\nJohn Hoadley, chief technology officer, Mobility and Converged Core Networks,\nNortel.\n\"Nortel's latest demonstration confirms that subscriber count and\ncapacity gains of OFDM-MIMO can be delivered even where individual devices are\nnot MIMO-enabled with multiple transmit antennas. Collaborative MIMO provides\nthe greater uplink capacity and spectral efficiency needed by operators to\ndeliver a full mobile broadband experience which will include internet, video\nand VoIP cost-effectively across a wide range of devices,\" he said.\nThe demonstration at Nortel's Advanced Wireless Lab in Ottawa, used\nMultiple-Input, Multiple-Output (MIMO), an emerging wireless antenna\ntechnology that will serve as the foundation of Nortel's 4G Mobile Broadband\nsolutions.\nFor the demonstration, Nortel used MIMO-enabled multiple antennas at the\ncell site and on 4G devices together with orthogonal frequency division\nmultiplexing (OFDM) transmission technology. Previous Nortel and industry\nresearch has shown that a combination of these two technologies offers the\nability to deliver the highest network bandwidth and greatest spectral\nefficiency capabilities at the lowest cost.\nWith OFDM, a single channel within a spectrum band is divided into\nmultiple, smaller sub-carriers that transmit information simultaneously\nwithout interference. MIMO allows multiple data streams to be transmitted at\nthe same time and on the same sub-carriers through interference-free MIMO\nspatia...
