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. |

DETAILED DESCRIPTION The present invention addresses this need by providing a method and apparatus for measuring idle channel quality in a radio frequency (RF) system. The method of measuring idle channel quality includes the steps of performing a first signal quality measurement of a channel in the RF system, comparing the first signal quality measurement to a threshold, and keying the channel when the first signal quality measurement exceeds the threshold. According to one aspect of the present invention, the apparatus for performing idle channel measurements includes an antenna, a transmitter coupled to the antenna, a receiver in communication with the antenna, an idle channel measurement unit, and a channel allocator in communication with the idle channel measurement unit and the transmitter. The channel allocator receives channel measurements from the channel measurement unit and keys an idle channel in response to a comparison between the channel measurements and a threshold when the channel measurement exceeds the threshold. The invention itself, together with its attendant advantages, will best be understood by reference to the following detailed description, taken in conjunction with the accompanying drawings.
