In spectrum sharing, incumbents are concerned about interference to their oper- ations caused by spectrum entrants. Technical approaches, such as cognitive radios, spectrum databases, etc. have been developed in an attempt to minimize this inter- ference. 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 shar- ing 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.
