ABSTRACT:
There is described a radio communications system, including a unit which is able to communicate over a radio communications network such as a satellite or cellular system, and is also able to communicate with a device such as a portable handset over a short range radio link. In order to avoid potentially troublesome interference on the communications path with the communications network, the unit is able to detect the strength of signals received on the short range radio link, and alert the user if those signals are such as to be a potential source of interference.
