The proposal, which is backed by Atheros, Intel, Sony, Matsushita, Toshiba, and others, must now garner a 75 percent "supermajority" vote at the next IEEE meeting in May. The TGn Sync won in a head-to-head vote against the WWiSE proposal, led by a collection of communications companies including Airgo Networks, Broadcom, Conexant, Motorola, Nokia, and Texas Instruments.
The vote makes the TGn Sync proposal all but certain to win the IEEE's approval as the next IEEE
Both the TGN Sync and defeated WWiSE proposals use an array of antennas known as MIMO (multiple-in, multiple-out) to better shape the signal. Both technologies have proposed using both 20-MHz channels and even 40-MHz and 60-MHz extensions, both of which are not currently permitted in Japan. The TGN Sync proposal also claims that the technology will be interoperable with current 802.11a/b/g standards.
The actual IEEE vote tally gave 181 votes to the TGn Sync proposal and 140 votes to WWiSE, according to a representative from Atheros Communications.
