About Us

Why We Are Here

SignalFrame was founded as Wireless Registry in 2013 to organize the emerging landscape of wireless signals. It was clear that wireless connectivity would become deeply rooted into our environment, and that there was an opportunity to organize this emergent space.

As the number and variety of wireless things exploded, Wireless Registry embraced a self-organizing graph data strategy to manage dynamic scale requirements. SignalGraph was born, and soon demonstrated how streaming graph services and advanced AI/ML resolutions can deliver against the founding ideas of organizing the worlds wireless signals. The company officially became SignalFrame in January 2019.

Digital Location Evolution


Introduction of the commercial Internet launches era of digitization. End-users connect to networks via ethernet. IP geolocation provides initial capability to manage access and content by location.

Late 1990s

Introduction of WiFi and Bluetooth protocols, providing wireless connectivity for the first time.


Apple iPhone introduced, bringing wireless internet, GPS, and maps to the masses. Other vendors quickly follow, and the location-enabled services industry is launched.


Location-enabled services expand exponentially, spawning sophisticated mobile targeting capabilities along with concerns over data privacy, lat/lon spoofing, and unwanted tracking.


A new generation of location-enabled services - Proximity Services - emerges that builds upon traditional location-enabled services by improving precision, providing additional security, and addressing privacy concerns of legacy lat/lon offerings.
