Abstract
A one-way direct sequence spread spectrum (DSSS) communications wide-area network is used as the data collection channel (uplink) of an automatic meter reading (AMR) application and a paging network, or other suitable downlink network, is used as an optional forward (downlink) channel in a cost-effective manner. The network is simple to deploy, highly scalable and modular. It offers a wide range of service options, from basic daily meter readings to advanced applications based on interval consumption data, to full two-way applications, while keeping the system's deployment and ongoing costs proportional to the service options and capacity requirements selected for various segments of the meter population. A high-output-power meter module is introduced, which provides significant benefits when operating on the network.
