Most Automatic Meter Reading (AMR) systems installed in utilities use radio frequency (RF) communication. RF communication is also used for two-way radios, wireless supervisory control, data acquisition (SCADA) systems, office wireless networks, routers and cell phones.
In an AMR system, the AMR endpoint (transmitter), located on or near the utility meter, transmits meter reading information via RF. If the endpoint is a two-way design, it can also receive information and instructions from the utility. If the utility uses a mobile dada collection system, the receiver collects and stores meter information to transfer to the utility billing system.
