Patent ID: 8798121

Claim:
A circuit comprises: a first wireless interface circuit that communicates packetized data in a common frequency spectrum to a first external device in accordance with a first wireless communication protocol; a second wireless interface circuit that communicates packetized data in the common frequency spectrum to a second external device in accordance with a second wireless communication protocol; and a plurality of signal lines, coupled to the first wireless interface circuit and the second wireless interface circuit, that communicate cooperation data between the first wireless interface circuit and the second wireless interface circuit, wherein the cooperation data is used by the first wireless interface circuit and the second wireless interface circuit to limit interference between the packetized data communicated in accordance with the first wireless communication protocol and the packetized data communicated in accordance with the second wireless communication protocol in the common frequency spectrum, wherein the cooperation data includes intra-device status messages between the first wireless interface circuit and the second wireless interface circuit that indicate when transmission of the packetized data is currently in progress and when reception of the packetized data is currently in progress by a selected one of: the first wireless interface circuit and the second wireless interface circuit, in accordance with one of: the first wireless communication protocol; and the second wireless communication protocol in the common frequency spectrum.
