US 7,009,530 B2 · Modular wireless fixed network for wide-area metering data collection and meter module apparatus

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.

Claims2

Dependent claims

A low cost Binary Phase Shift Keying (BPSK) RF signal modulator, implemented on a four-layer PCB, providing high performance at a very low cost compared to microwave monolithic integrated circuit (MMIC) BPSK modulators, said modulator having means switched to provide one of:

an in-phase output signal, and an inverted-phase output signal and power dividing means at the input and output of said means switched to provide one of:
an in-phase output signal, and an inverted-phase output signal.

Dependencies are inferred from the claim text.
