Claim of US Patent No. 10,368,303

1. A radiofrequency system comprising:a plurality of transceivers providing a plurality of channels; and
circuitry configured to perform off-channel functions; wherein:
a first subset of the plurality of channels performs radiofrequency communication functions; and
a second subset of the plurality of channels provides signals for the off-channel functions; and
the circuitry configured to perform the off-channel functions scans available communications channels for interference, and includes memory that stores identifications of interference-free channels, and, upon detection of interference on a channel in use in the first subset of the plurality of channels, selects one of the interference-free channels whose identification is stored, for use in the first subset of the plurality of channels.
