Patent ID: 8730927

Claim:
A first radio configured to operate according to a first protocol and configured to use a coexistence signaling scheme with a second radio configured to operate according to a second protocol, the coexistence signaling scheme being configured to allow a radio configured to operate according to the second protocol to be co-located and non-interfering with a third radio configured to operate according to a third protocol that is different to the first protocol, the first radio comprising: interface logic for generating messages for the second radio in accordance with the coexistence signaling scheme to cause the second radio to adopt behavior suitable for coexistence with the first radio, said generated messages suitable for being generated by the third radio; wherein the coexistence signaling scheme is suitable for allowing an IEEE 802.11 radio and a Bluetooth radio to be co-located and non-interfering; wherein the first protocol is a protocol other than Bluetooth and IEEE 802.11 and the second protocol is IEEE 802.11 protocol; wherein coexistence signaling scheme is implemented using a 2-wire coexistence signaling arrangement, comprising: a first signal line for transmitting a signal from the first radio to the second radio and suitable for being asserted by a Bluetooth radio whenever it is receiving a packet that it considers to be high priority; and a second signal line for transmitting a signal from the second radio to the first radio asserted by the IEEE 802.11 radio whenever it is receiving or transmitting; and wherein the interface logic is configured to cause the first radio to assert the first signal line for a period for which the first radio expects to receive a beacon of the first protocol.
