ABSTRACT:
Calibration signals can be sent on a traffic channel without interrupting a connection between two radios. In one embodiment, the present invention includes receiving, at a second radio, a first traffic signal transmitted on a traffic channel by a first radio during a first time interval, receiving, at the second radio, a calibration signal transmitted on the traffic channel by the first radio during a second time interval, and receiving, at the second radio, a second traffic signal transmitted on the traffic channel by the first radio during a third time interval, wherein the traffic channel supports a connection between the first and second radios.
