Patent ID: 8284721

Claim:
Apparatus having multiple air interfaces, comprising: a plurality of first antenna elements configured to communicate on a first air interface; at least one second antenna element configured to communicate on a second air interface; first front end circuitry operatively coupled with said plurality of first antenna elements, said first front end circuitry enabling transmitting and receiving signals over said first air interface; second front end circuitry operatively coupled with said at least one second antenna element, said second front end circuitry enabling transmitting and receiving signals over said second air interface; a communication channel between said first air interface and said second air interface and adapted to carry activity information; and a processor communicatively coupled to said first front end circuitry and said second front end circuitry; said processor configured to: determine an isolation between antennae pairs formed from said plurality of first antenna elements and said at least one second antenna element; evaluate whether said isolations are symmetric or asymmetric; and based at least in part on said evaluation, not using of at least one antenna element from said plurality of first antennae.
