Abstract
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).
