Abstract
Methods, apparatus and systems supporting coexistence of wireless transmission equipment in shared wireless medium environments. The techniques provided herein may be applied to various types of wireless transmission equipment. Under one example, a wireless power transmission system (WPTS) delivers power to wireless power receiver clients via transmission of wireless power 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 WPTS is configured to co-exist 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 PHY and MAC protocols used for 802.11 (Wi-Fi™) networks.
