    Responsible Monetization of Geolocation. The Gateway Mobile Location Center (GMLC) provides secure, anonymous and standards-based access to subscriber location using network-based positioning methods including SUPL (Secure User Plane Location) where higher accuracy is required, without relying on smartphone apps or GPS tracking, fully respecting user privacy. The GMLC enables mobile operators to support public safety alerts, provide IoT asset tracking information, complement marketing efforts with a geographically relevant perspective, and deliver location-based services (LBS) for personal security and basic authentication use cases. Mobile operators hold one of the most powerful assets in digital services: location data, yet they often struggle to monetize it safely and efficiently. With PAiCore’s GMLC, operators stay in full control of how geolocation data is used and shared, while supporting high-availability deployments in active-active or active-passive configurations.
