Abstract
A radiofrequency system includes a plurality of transceivers providing a plurality of channels, and circuitry configured to perform off-channel functions. A first subset of channels performs radiofrequency communication functions, and a second subset of channels provides signals for the off-channel functions. The first subset of channels may be provided by a first subset of transceivers, and the second subset of channels may be provided by a second subset of transceivers. A spectrum sensing unit may select between the first subset of transceivers and the second subset of transceivers. The circuitry configured to perform the off-channel functions may use the second subset of the plurality of channels to perform neighborhood discovery. The circuitry configured to perform the off-channel functions may scan available communications channels for interference, storing identifications of interference-free channels, and, upon detection of interference on a channel in use, may select one of the interference-free channels.
