Abstract
Methods, apparatus and systems supporting coexistence of wireless devices and equipment in shared wireless medium environments through the use of multiple PHYs. The techniques provided herein may be applied to various types of wireless devices and equipment. Under one example, a wireless device transmits and/or receives signals using one or more frequencies and/or channels within shared wireless medium environments in which other wireless equipment is operating, such as access points and stations in wireless local area networks (WLANs). The wireless devices are configured to coexist with the operations of the other wireless equipment within the shared wireless medium environment by adapting its transmission operations to utilize frequencies or channels that do not interfere with other equipment and/or implementing co-channel and shared channels operations under which access to channels is implemented using standardized WLAN protocols such as, but not limited to PHY and MAC protocols used for 802.11 (Wi-Fi™) networks.
