1. Apparatus, comprising:
- a transmitter for simultaneously transmitting voice and data in respective spectral regions of a communications channel, said data comprising an identification code associated with a desired wireless device;
And a receiver, for receiving voice and data via respective spectral regions of said communications channel from said desired wireless device; and
means for changing said communication channel utilized by said transmitter in response to an indication that data transmitted via said transmitter said desired wireless device fails to satisfy at least one criterion;

4. A computer readable medium containing software instructions that, when executed by a processor, performs the steps of:
-
simultaneously transmitting available audio and identification data in respective spectral regions modulated onto a radio frequency (RF) carrier signal of a communication channel; and
in the absence of a favorable response from a wireless device corresponding to said identification data, selecting a next communication channel.

5. In a wireless communications system utilizing a plurality of communications channels, each channel having associated with it a respective carrier frequency for propagating audio data in a first spectral region and non-audio data in a second spectral region, a method comprising:
-
(a) selecting an initial communications channel for communicating with a desired wireless device;
(b) determining if a received signal strength indicator (RSSI) of said selected communications channel indicates that said desired wireless device is active; and
, if so(c) transmitting, via said selected communications channel, an identification code of said active wireless device, said identification code comprising non-audio data;
otherwise(d) repeating step (c) up to a predetermined number of times until said desired wireless device has responded to said transmitted identification code; and
(e) if said desired wireless device has not responded to said transmitted identification code, selecting(430) a next communications channel and repeating steps (b) through (d). - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
