Federal Communications Commission rules for the 3.5 GHz citizens broadband radio service (CBRS) permit commercial systems to share 150 MHz of bandwidth with federal and other incumbents. To protect the federal incumbents, a spectrum coordinator?the spectrum access system (SAS)?uses a standardized algorithm to suspend some commercial transmissions when a nearby incumbent (e.g., a shipborne radar) becomes active. Using propagation models based on those employed by the SAS for interference management, the data herein was used to quantify the impact of federal incumbent activity on commercial service, in terms of both the numbers of transmissions affected and their service area. These metrics are also used to examine the tradeoff between commercial coverage and immunity to incumbent activity as a function of commercial base station antenna height. The data include Simulated Citizens Broadband Radio Service device deployments, calculated federal incumbent protection move lists, and calculated coverage contours. The data is associated with the publication, "Effect of Federal Incumbent Activity on CBRS Commercial Service," M. R. Souryal and T. T. Nguyen, in Proc. IEEE DySPAN, Nov. 2019.
