    摘要： A system for managing a distributed array of appliances includes a headend computer having a low power main transceiver and a distributed array of relay units. Each relay unit includes a low power satellite transceiver, a microcomputer connected to the satellite transceiver, the satellite transceiver being controlled by relay program instructions for detecting communications directed by the headend computer relative to the same relay unit and directing communications to the headend computer relative to the same relay unit, and for retransmitting communications to other relay units. At least some of the relay units are appliance controllers and include an appliance interface for communicating with the appliance, the microcomputer being also connected to the appliance interface and having program instructions for directing communication between the satellite transceiver and the appliance interface. Each of the relay units has a unique address associated therewith, occurrences of the unique address being detected in communications from the headend computer. Each of the transceivers has an effective range of not less than approximately 60 feet or more depending on the frequency, which can be between 66 KHz and 2.6 GHz. The transceiver can selectively operate on one of at least 16 carrier frequencies, or one of several spread spectrum channels. Also disclosed is a method for controlling a distributed array of appliances from the headend computer.
