Benefits of AMR
Quick (data acquired remotely during drive by-5 days vs 4 hrs)
Meter data communicated by Radio Frequency—no manual meter reading
No need to access the meter box during routine drive by, except in unique situations
Lower O&M (labor and disputes) 1 hr Consumption history can be extracted to
respond to disputes Can detect customer leaks and help identify water
theft Lower meter reader turnover Streamline high bill investigations

RF used for everything else, why not for AMR
Technologies that depend on radio waves: AM and FM radio broadcasts Cordless phones Garage door openers Radio-controlled toys Television broadcasts Cell phones GPS receivers Satellite communications Police radios Wireless clocks Radar and microwave ovens Communication and navigation satellites Modern aviation Wireless Internet access Radio waves are electromagnetic, part of the light spectrum and
travel at a speed of 186,282 miles per second—the speed of light
Guglielmo Marconi built the 1st Radio Transmitter in 1895

Desired AMR Features
Read remotely under submerged conditions
Integrate continuous leak detection and retrievable consumption history
Use vandal deterrent technologies in unlicensed frequency
Be one-piece, integrated unit with no exposed wiring to look similar to a manual meter
Fixed network AMI preferred, but Mobile AMR considered in analysis
