An automatic meter reading (AMR) system collects readings from multiple or individual
meters or sets parameters in individual or multiple meters using the Short Message
Service (SMS) in digital cellular networks. The individual meters incorporate interfaces
to the SMS network so that parameters within the meter can be read and written
to/from external devices that also interface to the SMS network. Communications
gateways incorporate a single interface to the SMS network, which a set of non-SMS-enabled
meters can access via a local area network (LAN).
