What We Do Saving Time. Saving Lives.
3
LaaSer solves the deadly global problem that when callers from mobile devices require emergency services, that the providers of those services
cannot locate the caller.
This problem costs tens of thousands of lives annually around the globe and costs individuals, companies, and
governments billions of dollars.
We make 9-1-1 work the way people thought it already did.
Confidential and Proprietary. NDA required for distribution.
Sensor data collected at the point the user dials 9-1-1. Timings and behaviors are policy-driven with policies
customizable per MNO and/or OEM and/or jurisdictional
preferences.
Sensor data is sent to the LaaSer platform for analysis
and combination with exogenous and inferential data
to algorithmically determine location with a highly credible
uncertainty factor.

Conclusion
• Deploying Next Generation 9-1-1 does not mean better location accuracy or routing. Location is still dependent upon the source.
• LIS and ADR sources, like LaaSer, provide enhanced location and supplemental data that will help public safety.
• Jurisdictions will need to decide/authorize the use of supplemental data sources when they deploy Next Generation 9-1-1. o Such data sources are not currently provided by the carriers and, hence, are not
regulated. o Policy rules will need to apply for routing logic.
• NGCS functional element and call handling systems will need to support the integration and support of supplemental data sources.
