As important as Citizen Broadband Radio Service (CBRS) likely will be for venue communications, it might be more important for competitive internet service providers or application providers seeking to use the shared spectrum platform for outdoor access use cases.
CBRS makes up to 150 MHz of new spectrum available, of which 70 MHz can be used in 10-MHz allotments sing the licensed approach, or up to 80 MHz by any single service provider in an area, using the unlicensed approach.
To evaluate the potential upside for a competitive service provider, consider that some tier-one U.S. mobile service providers have only about 130 MHz of total licensed spectrum. Incumbents might be more inclined to use CBRS as a supplement to existing spectrum. Upstarts are more likely to use CBRS in standalone fashion.
To be sure, would-be users of CBRS in outdoors settings have other platforms and approaches to consider, ranging from new 5-GHz licensed or unlicensed spectrum, Wi-Fi spectrum aggregation, reliance on small cell architectures and use of advanced radio platforms as well.
