Coordinate-based 911 routing

Coordinate Based Routing (CRDB) performs selective routing on a 911 call based on the X, Y coordinates from which the call originated.

The X, Y coordinates respectively represent the longitude and latitude of a geographic position. The CRDB provides a translation between a given position expressed in X,Y coordinates to an Emergency Services Zone (ERZ) by determining the ESZ in which the coordinates are located.

How is Bandwidth involved with CRDB?

CRDB is one of the three 911 routing options that Bandwidth offers. Coordinate Routing is ideal for Over-the-Top (OTT) mobile VoIP providers or IoT devices with mobile connectivity. If your users are constantly moving and don’t have a set location, then this is the ideal 911 service for your business.

Our customers that utilize CRDB range from app developers to businesses looking for a backup 911 service when a traditional address cannot be provided. CRDB differs from address-based routing by using an individual’s latitude and longitude coordinates such as those provided by a GPS unit in a mobile phone.

When a 911 call is placed, Bandwidth is able to assess these coordinates and compare them to our PSAP boundaries files. From there we route the call directly to the proper PSAP. As an additional service, we offer reverse geocoding as another option to provide a physical address within seconds.
