Patent ID: 8811369

Claim:
A method of operating a first communications device, comprising: selecting between a first mode of operation and a second mode of operation, said first mode of operation using a first set of parameters to operate said first communications device when communicating in a first frequency band, said first set of parameters including a parameter specifying a first tone spacing, said second mode of operation using a second set of parameters to operate said first communications device when communicating in a second frequency band, said second set of parameters having a predetermined relationship to the first set of parameters; and making at least one device setting change in accordance with said predetermined relationship when a current mode of operation is different from a selected mode of operation, said at least one device setting change including changing a control parameter in the first communications device by an integer multiple representing a predetermined difference between a parameter in the first and second sets of parameters, said at least one device setting change being one of an oscillator rate change, a timing change, or a frequency change, said change being by an integer multiple of a corresponding parameter in said first set of parameters.
