Patent ID: 6842625

Claim:
A method for reliable data communications system in a communications system, the method comprising the steps of: determining a first data rate; determining a first power level required to transceive at the first data rate; determining a first predetermined function; using the first predetermined function to select a first transceiver frequency channel, the first transceiver frequency channel having at least one sub-channel associated with the first transceiver frequency channel; determining if the first transceiver frequency channel is available, wherein the step of determining if the first transceiver frequency is available further comprises the steps of: determining a first transceiver power level required to transceive on the first transceiver frequency channel; comparing the first transceiver power level required to transceive on the first transceiver frequency channel with the first power level; transceiving data on the first transceiver frequency channel in response to the step of determining based upon the step of comparing the first transceiver power level required to transceive on the first transceiver frequency channel with the first power level; changing the first transceiver frequency channel to a second transceiver frequency channel in response to the step of determining the first transceiver frequency channel is not available, the second transceiver frequency channel having at least one sub-channel associated with the second transceiver frequency channel, wherein the second transceiver frequency channel is associated with the first data rate, wherein the step of changing the first transceiver frequency channel to a second transceiver frequency channel further comprises the steps of: using a second predetermined function to select a second transceiver frequency channel; determining a second transceiver power level required to transceive on the second transceiver frequency channel; comparing the second transceiver power required to transceive on the second transceiver frequency channel with the first power level; transceiving data on the second transceiver frequency channel in response to the step of determining if the second transceiver frequency channel is available; and alerting a user in response to the step of determining if the second transceiver frequency channel is not available.
