Abstract

See full text

A wireless RF communication system that shares frequency assignment with existing RF systems scans a set of possible operating frequencies for signals transmitted by the other systems. This data is sent to a frequency management center where a safe operating frequency is assigned. The new RF system periodically scans the set of frequencies and will automatically inhibit transmissions if a signal from another system is detected which exceeds a threshold, thereby indicating that a possibility exists for interference.
