1. An antenna switching system comprising:
- a first transceiver of a plurality of transceivers;
a first processor configured to process an application stored in memory;
a second transceiver of the plurality of transceivers electrically connected between the first processor and the first transceiver, the second transceiver configured to relay messages from the first processor to the first transceiver;
a switch configured to connect a plurality of transceivers to at least one antenna; and
a second processor configured to control the connection of the switch to one or more of the first and second transceivers.

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.

11. A method of switching of at least one antenna:
-
providing at least a first transceiver and a second transceiver of a plurality of transceivers; providing a signal from a first processor to a first transceiver of the plurality of transceivers electrically connected between the first processor and the second transceiver; determining whether the signal is to be transmitted by the first transceiver or the second transceiver; relaying the signal from the first transceiver to the second transceiver if the determination is made that the data is to be transmitted by the second transceiver; and switching an antenna switch to electrically connect one of the first and second transceivers to at least one antenna of a plurality of antennas, the connected transceiver corresponding to the determination of whether the signal is be transmitted by the first transceiver or the second transceiver. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
