Precision Built for the Way People Listen
With most radio listening happening in the car, GBS designs its Geo-Targeting technologies around real-world traffic patterns and listener movement. This ensures geo-fenced audio, text, and visual messages reach drivers exactly when and where they matter most.
Geo-Fencing Built for Real-World Performance
GBS develops precise carrier-to-interference (C/I+N) curves for digital delivery, including RBDS and HD Radio, through extensive testing in the Chicago-based GBS Lab and across partner broadcast networks. These measurements create clear, predictable geo-fence boundaries essential for high-quality localized messaging.
Analog FM geo-fencing performance has already been fully engineered, validated, and deployed through extensive ZoneCasting™ trials, demonstrating consistent, seamless audio transitions as drivers move between zones.
Predictable Coverage Through Advanced RF Modeling
Each deployment is engineered using terrain-aware RF modeling, drive testing, and synchronized signal optimization. This ensures well-defined, interference-free zone boundaries and a seamless listener experience.
ZoneCasting™: Deliver Localized Content Within a Single Signal
ZoneCasting™ is GBS’s patented technology that allows an FM station to divide its coverage area into multiple, precisely defined geographic “zones.” Instead of broadcasting one identical message across the entire market, stations can deliver different ads, alerts, promotions, or community updates to specific areas, while maintaining a seamless listening experience.
Using synchronized MaxxCasting™ nodes, ZoneCasting™ creates localized content windows that align with real-world mobility patterns, making it possible to tailor broadcast messages to neighborhoods, districts, suburbs, commuter routes, and more.
Listeners hear programming relevant to where they are, and advertisers gain access to new hyper-local inventory that was previously impossible in traditional FM broadcasting.
Applications & Revenue Opportunities
Geo-Targeting empowers stations to deliver messaging that was once only possible through digital platforms, including:
Creating new, high-value advertising inventory tied directly to geography.
Tourism, venue, and district-based promotions
Political and issue-based communications targeted to relevant geographies
Localized weather and traffic reports aligned to each zone
Hyper-local advertising for retail, dining, entertainment, and services
Community-specific alerts, events, and updates
Localized emergency and public-safety messaging
Built for Broadcaster Workflows:
MaxxCasting™ and ZoneCasting™ integrate smoothly with existing station systems, including:
Automation and traffic systems
HD Radio infrastructure
STL paths and network routing
Monitoring, logging, and compliance workflows
This reduces operational friction while enabling stations to scale localized content effortlessly.
