In spectrum sharing, incumbents are concerned about interference to their operations caused by spectrum entrants. Technical approaches, such as cognitive radios, spectrum databases, etc. have been developed in an attempt to minimize this interference. Whether the interference is co-channel or adjacent-channel, the power level of the interfering signal depends on the number of entrant radios and their spatial relationship to the incumbent operations.
In this paper, we report on a modelling approach that is based on technology adoption literature and uses a tool that was developed for epidemiology to empirically estimate received signal power in a particular geographic location for a particular sharing framework (CBRS). Using this tool, we can estimate the received signal strength a particular points in space (US Naval base, in particular) under different technology adoption profiles, and allow these to change over time.
