Abstract
An arbiter circuit receives a plurality of media access request signals from multiple protocol processing devices, and generates a plurality of media access grant indicators using i) the plurality of media access request signals, and ii) coexistence arbitration rules. A selector circuit receives the plurality of media access grant indicators from the arbiter circuit, and when the plurality of media access grant indicators indicate more than one protocol processing device is authorized to access an antenna, determines a compatibility of the more than one protocol processing device simultaneously accessing the antenna. The selector circuit, based on i) the plurality of media access grant indicators, and ii) the determined compatibility of the more than one protocol processing device simultaneously accessing the antenna, controls one or more switches to selectively enable antenna paths in a plurality of antenna paths coupled to the antenna.
