Abstract

An automatic meter reading (AMR) system includes a fixed or mobile reader and an endpoint interfaced to a utility meter. The fixed or mobile reader is capable of communicating with the endpoint via RF communication. The fixed or mobile reader sends a message to the endpoint that includes a response mode direction which directs the endpoint to respond to the reader via either a mobile network mode or a fixed network mode. The AMR system allows implementation of, and migration between, one-way, one-and-a-half-way, and two-way communications system modes without requiring reprogramming, reconfiguring the metering endpoints or going through a reconfiguration cycle before effecting a communication
