ABSTRACT:
A method of measuring idle channel quality which includes the steps of performing a first signal quality measurement (200), comparing the measurement to a threshold (202), and keying the channel (204) in response to the comparison (202) when the signal quality measurement exceeds the threshold. An apparatus for measuring idle channel quality comprising an antenna (116), a transmitter (110) coupled to the antenna (116), a receiver (110) in communication with the antenna (116), an idle channel measurement unit (112), and a channel allocator (102) in communication with the receiver and the transmitter (110). The channel allocator (102) receives channel measurements from the channel measurement unit (112) and keys an idle channel in response to a comparison between the channel measurements and a threshold when the signal quality measurement exceeds the threshold. In response to the keying, a CDPD system (14) stops transmitting on the channel.
