  • Patent number: 5142691
    Abstract: 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.

  • Patent number: 4817190
    Abstract: An improved communication system is disclosed wherein at least one reprogramming station is added to a communication system. The reprogramming station is constructed and arranged to communicate with the subscriber units thereby either reprogramming or regrouping them. The subscribing units receive the reprogramming command and acknowledge individually, altering a memory means until either reprogrammed back to the original state, or to another state. In another mode, the reprogramming station transmits a regrouping command wherein two or more groups are combined to form a super group.
