Because the majority of broadcast radio listening happens in the car, we focus on traffic analytics for the Geo-Fencing aspect of MaxxCasting™️ and ZoneCasting™️. For text and graphical messaging, carrier-to-interference (C/I+N) curves are developed for digital signals- both RBDS and HD Radio- in the GBS Lab in Chicago and in our Broadcast partners networks. Analog FM audio Geo-Fencing performance has already clearly been developed, tested, and deployed by GBS in the ZoneCasting™️ trials.
This platform has been successfully tested under special FCC authorization. There is now a Notice of Proposed Rule Making (NPRM) at the FCC which would allow full time Geo-Targeted separation of the main channel of an FM radio station to its listeners. This ability to split an FM signal into local “zones” has gathered exceptional industry support.
