ABSTRACT:
An interface between radios supporting different air interfaces is disclosed that avoids some of the costs and disadvantages associated with inter-radio interfaces in the prior art. The present invention enables the needed coordination across multiple wireless protocols, such as 802.11 and Bluetooth, by providing a communication link spanning different integrated circuits when each radio is on a separate integrated circuit. This low cost, low complexity link can be added to standard integrated circuits produced by individual companies without adding appreciably to the overall cost of the integrated circuits.
