Abstract
A method, apparatus, and system are disclosed for providing communication between a utility meter and a remote station via any of a plurality of RF modulation schemes and communication protocols over any of a plurality of carrier frequencies. The utility meter includes adaptive radio circuitry that is preferably programmably configured to receive and process any format of incoming signals, and generate and send any format of outgoing signals. The adaptive radio circuitry includes a DSP, filters, an analog-to-digital converter, a digital-to-analog converter, a tunable broad-band up/down converter and other processing circuitry. A main processor and memory provides control over the adaptive radio module.
