Exploring the Utilization of CBRS Spectrum through Crowdsourced Measurements

This paper presents a novel methodology to assess the effectiveness of the Citizens Broadband Radio Service (CBRS) spectrum-sharing framework. Using end-user crowdsourced measurements, we analyze the use and adoption of CBRS across various market stakeholders—including Mobile Network Operators (MNOs), Regional MNOs, Mobile Virtual Network Operators (MVNOs), Wireless Internet Service Providers (WISPs), Neutral Hosts, and Private Networks. We provide key insights into CBRS usage, with some MNOs leveraging the spectrum to enhance network capacity on a secondary basis and MVNOs affiliated with cable operators deploying their own infrastructure in high-traffic areas. Beyond the preliminary results, this study establishes a foundation for evaluating the effectiveness of CBRS in fostering competition, innovation, and efficient spectrum use, while offering a framework for further research as regulatory reforms and market dynamics evolve.
