ABSTRACT:
A one way direct sequence spread spectrum (DSSS) communications wide-area network is the data collection channel (uplink) of an automatic meter reading (AMR) system, and a paging network, or other suitable communication channel is the optional forward (downlink) channel. The communications network may include one-way meter modules (transmitters) each communicatively coupled to a corresponding electric, gas or water utility meter, and may include two-way meter modules (transceivers) each coupled to such a corresponding utility meter. The meter modules monitor, store, encode and periodically transmit metering data via radio signals (air messages) in an appropriate RF channel. Metering data air messages are collected by a network of receiver Base Stations (BS) and forwarded to a Data Operations Center (DOC), which acts as a metering data gateway. The reception range of each base station is typically over 5 miles in urban areas, allowing sparse infrastructure deployment for a wide variety of metering data collection applications.
