Abstract

A remote data collection system for collecting usage data from an endpoint.
The monitoring module (40) has a wireless transmitter to transmit the usage data. The system also includes a receiver (100) to receive usage data from the wireless transmitter of the monitoring modules, the receiver is capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel.
