California Wireless E9-1-1

Routing on Empirical Data



9-1-1Office Mission

To enable Public Safety Answering Points to provide the fastest, most reliable, cost-effective and secure access to emergency services from any device, anywhere.


US Subscribers grew from 60M in 1998 to 276.6M in 2009. Worldwide there are 2.5B subscribers*

89% of the US population uses cell phones and used a total of 2.23 Trillion wireless minutes in 2009.*

20.2% of US households are “Wireless only.”*

Californians placed 24.8M E9-1-1 calls in 2009. 16.6M (67%) were wireless and 8.2M (33%) were landline.

68,098 E9-1-1 calls are made everyday in California with 45,530 of them being wireless.

California has deployed 122,531 total cell sectors. 23,385 or 20% were deployed in 2009.

Time Critical Issues

Routing to Local PSAPs allows Police, Fire and EMS to respond quicker to their communities needs.

  • Size of a fire doubles every minute*
  • 1 Min 8 Min

A person who has stopped breathing or has

had a heart attack needs CPR within 6 minutes.*

    • Ventricular Fibrillation
    • Crimes in progress have a better chance of being stopped.

Without CPR

Death in 6 minutes



Routing on Empirical Data

Enable PSAPs to Analyze

Emergency Call Record Data using a Web based Geographic Information System

to Collaboratively Determine the Most Efficient Path

to Route Calls.



The RED Project has demonstrated an accurate call sector analysis is the best method to determine wireless routing.

On average, 51.0% of sectors currently routed to the CHP are being rerouted from the CHP to Local PSAPs.



RED I - Ventura and Santa Barbara counties is complete.

RED II - Bay and Monterey Area concludes in April 2010.

RED III - SOCAL (less LA) is in progress and ends in June 2010.

RED IV - LA County, Central and Northern CA has not yet been awarded.

RED:Routing on Empirical Data Project Implementation

Implementation of the RED Project phases encompasses dozens of processes and requires the participation and collaboration of all the major stakeholders including the CHP, County Coordinators, PSAP Managers, Wireless Service Providers, the State 9-1-1 office, as facilitated by Public Safety Network.

Implementation falls into four primary categories…


WSP Maintenance Testing

  • The 9-1-1 Office recommends WSPs follow the NENA E9-1-1 Wireless Testing Procedure outlined in the NENA 57-002 standard to determine when to test with PSAPs.
    • WSPs have the ability to perform internal routine maintenance test of cell sectors without the call being delivered to the PSAP.
    • WSPs should be placing E9-1-1 test calls to the PSAPs only when initially deploying a PSAP, a physical change has been made to a sector, or when an ESN routing assignment has been changed.
