Patent ID: 7366128

Claim:
A system comprising: a fixed unit having a fixed transceiver; a portable unit having a portable transceiver, wherein the portable transceiver and the fixed transceiver communicate via a first RF link; an additional transceiver coupled to one of the fixed unit and the portable unit, wherein the additional transceiver facilitates communication between the portable unit and a headset unit via a second RF link; a processor coupled to one of the fixed transceiver, the portable transceiver, and the additional transceiver, wherein the processor is configured to avoid interference between the first RF link and the second RF link, wherein the interference between the first RF link and the second RF link is avoided by multiplexing time slots associated with the first RF link and the second RF link, wherein the multiplexing is performed using timing information received from other signals from which the timing information can be derived, and wherein the multiplexing is performed using RSSI to derive timing information of the additional transceiver.
