Brown also said that part of the standard included so-called beam-forming technology, which recombines information being transmitted over the 5 GHz spectrum to make it more efficient; so rather transmitting data in all directions, it can aim a beam at whichever device is requesting information.
Buffalo says that its 802.11ac router should come out this fall. And when it does, it will contain two chipsets: one for 802.11n that transmits over the traditional 2.4 GHz band, and one for 802.11ac that will use the 5GHz band. This way, devices without 802.11ac capabilities will still be able to access Wi-Fi, although Brown expressed confidence that newer ultrabooks and next-generation tablets would be 802.11ac compatible.
While the 802.11ac standard has not been ratified yet–and probably will not be ratified before the end of 2012 if this year at all–Brown said that Buffalo has a history of selling routers before certification. The comapny was able to sell 802.11n routers before certification in 2009 and, it plans to do so with the next standard as well.
