Abstract

The invention is a universal receiver that addresses the problem of collecting consumption data from multiple types of utility metering wireless devices that use different and often proprietary protocols where such parameters are unknown to the system owner. The universal receiver automatically detects unknown AMR/AMI broadcasts utilizing know parameters for typical AMR/AMI signals and executing a decoding algorithm that includes series of RF parameter detection, signal characterization, signal decoding, and data qualifying techniques with minimal or no involvement needed by a user.
