The IEEE 802.11n Task Group this week winnowed out some proposals for a standard that's intended to increase wireless LAN throughput, not just the overall data rate, to at least 100Mbs.
Qualcomm withdrew its separate proposal and joined one of the two main groups remaining, while Motorola's proposal failed to win enough votes during the ballot to stay in the running.
Two main proposals remain: TgnSync, which includes Atheros Communications, Cisco, Intel, Nokia and now Qualcomm, got about 50 per cent of the votes; and WWiSE, which includes Airgo Networks, Broadcom, STI, and Texas Instruments, got about 34 per cent.
A proposal has to win at least 75 per cent to "win" as the basis for the standard. Both proposals are based on multiple input, multiple output technology, which generates two or more unique radio signals, and uses two or more transmit/receive antennas.
