1. A remote data collection system for collecting usage data from an endpoint, comprising:
- a monitoring module coupled to the endpoint, the monitoring module having a wireless transmitter to transmit the usage data, the wireless transmitter including;
a reference oscillator;
a low pass filter coupled to the reference oscillator;
a modulation filter to provide an over-sampled modulated signal;
a synthesizer coupled to the low pass filter and the modulation filter;
a sine wave generator coupled to the synthesizer; and
an antenna coupled to the sine wave generator; and
a receiver to receive usage data from the wireless transmitter of the monitoring module, the receiver capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel, including;
a radio frequency (RF) front end to convert an RF signal to a digitized signal;
a Fast Fourier Transform (FFT) generator coupled to the RF front-end to separate the digitized signal into a plurality of sub-channels;
a bank of phase locked loops (PLLs) coupled to the FFT generator, each PLL operating on a sub-channel with a sub-channel center;
a flag detector coupled to the bank of PLLs to detect variations from the sub-channel center and to recover the usage data transmitted by the end-point; and
a data communication network coupled to the receiver to communicate the usage data from the endpoint to a database.
