Abstract: A method of determining operating parameters for a secondary system transmitter is described. The transmitter characteristics, including location and operating frequency band, are provided to a geo-location database. The database determines the maximum allowable transmission power that meets various specifications for different channels and conveys the power and channel(s) to the transmitter. The database estimates channel incumbent signal strengths based on the transmitter location and primary and higher-priority secondary incumbent systems, estimates the splatter levels, determines whether adjacent and co-channel interference protection ratios are met, and adjusts the allowable power level accordingly. The database also estimates aggregate co- and adjacent channel primary and secondary incumbent system interference levels at the transmitter location and predicts channel quality for each allowable channel. The estimated levels are updated using measurements of actual levels at the transmitter location. The database dynamically allocates channels using the secondary system priorities.

Abstract: A communications method and device that enables multiple source devices (110, 120, 130) to communicate information to a destination device (100) is disclosed. The information communicated from any source device to the destination device (100) typically takes the form of binary electronic product codes ("EPC") or identification ("ID") information. The preferred embodiment of the invention utilizes the techniques of: data scrambling and descrambling; channel selection and transmission; enabling and disabling group transmissions; correlation; and collision mitigation.
