Method and apparatus for avoiding wireless audio signal transmission interferences
First Claim
1. A method avoiding interference from a first wireless system operating on a first frequency in a first range of frequencies in which a second wireless system may operate using spread spectrum techniques that has a plurality of frequency ranges including the first range and other frequency ranges outside said first range comprising,determining on the second wireless system the first frequency of active operation of the first wireless system, andcommunicating wirelessly on the second wireless system in the vicinity of wireless communication on the first wireless system while preventing the second wireless system from operating in the first frequency range andutilizing a spread-spectrum technique that operates in a frequency range outside said first frequency range without replacing said first frequency range with another frequency range.

10. A method avoiding interference from a first wireless system operating on a first frequency in a first range of frequencies in which a second wireless system may operate using spread spectrum techniques that has a plurality of frequency ranges including the first frequency range and other frequency ranges outside the first range comprising,
maintaining for the second wireless system, information about the first frequency, communicating on the second wireless system using a spread-spectrum technique in a frequency range outside said first range of frequencies, and controlling communicating on the second wireless system to exclude the first frequency without replacing said first frequency with another frequency.

14. An apparatus comprising
a second wireless system constructed and arranged to use spread spectrum techniques in a plurality of frequency ranges including a first frequency range embracing a first frequency on which a first wireless system operates that would have interference if said second wireless system operated in said first frequency range a controller to prevent operation of said second wireless system in said first frequency range without replacing said first frequency range with another frequency range.
