Patent ID: 8073500

Claim:
A multimode wireless device, comprising: a multimode transceiver module operatively coupled to at least one antenna, the multimode transceiver module comprising at least two communication access technology (CAT) transceiver modules operatively coupled to at least one antenna, wherein each CAT transceiver module complies with a CAT receiver requirement, wherein the at least two CAT transceiver modules comprise a first CAT transceiver module that is configured to enter an active state and a second CAT transceiver module that is configured to be in an inactive state; a CAT detection module operatively coupled to a CAT transceiver antenna, wherein the CAT detection module complies with different requirements than the CAT receiver requirements, the CAT detection module configured to detect a plurality of CAT RF energy levels associated with each CAT transceiver module, wherein the CAT detection module is further configured to detect CAT RF energy levels corresponding to the second CAT transceiver module in the inactive state; at least one CAT threshold level that is compared to the detected CAT RF energy levels so that the comparison is performed without activating the corresponding CAT receiver module.
