Future of 802.11nStandard has been ratified September 2009 afteryears of discussions. (IEEE 802.11n-2009)Standard is based on 802.11n Draft 2 specificationswith two streams, all other functions are optional.Interoperability remains a question mark for pre-NproductsNew products supporting technical features like:• Up to four spatial streams• Transmit Beamforming• Direct Link Setup … and many moreSHARKFEST ‘10 | Stanford University | June 14 –17, 2010
