1. A radio comprising:
- a channel-access controller fortransmitting a first idle indication signal to a collateral radio and for receiving a first transmit inhibit signal from said collateral radio; and
a host interface for receiving a first data block from a host interface bus, for providing said first data block to said channel-access controller, for receiving a second data block from said host interface bus, and for providing said second data block to said collateral radio.

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.

7. A multi-radio card comprising:
-
(a) a first radio for communicating in accordance with a first air interface wherein said first radio comprises; (1) a first channel-access controller for transmitting a first idle indication signal to a second radio and for receiving a first transmit inhibit signal and said second radio, and (2) a host interface for receiving a first data block from a host interface bus, for providing said first data block to said channel-access controller, for receiving a second data block from said host interface bus, and for providing said second data block to said second radio; and (b) said second radio for communicating in accordance with said second air interface, for receiving said first idle indication signal from said first radio and for transmitting said transmit inhibit signal to said first radio. - View Dependent Claims (8, 9)
