Abstract: A WiFi communications mechanism in which simultaneous transmission is negotiated and beamforming communications performed towards at least one station (STA), while nulling is performed towards one or more other access points (APs) to reduce interference. Omni-directional transmissions are utilized in a manner to overcome preamble interferences, which is used in combination with synchronizing symbol intervals to eliminate interference from symbol transitions. The enhanced simultaneous transmission protocol allows two APs to transmit simultaneously without interfering with one another.
