1.2 Ed Parsons, Google
Ed Parsons of Google presents an Emergency Location Service (ELS) that sends a mobile phone's location directly to emergency operators during a 911 call. ELS uses Google's Fused Location Provider to determine location more quickly and accurately than traditional methods, with accuracy often within 17 meters. It has already provided over 10,000 emergency locations per day in tests in the UK. Parsons invites interested parties to contact him or visit a website to learn how to configure endpoints to receive emergency location data from Android devices.

- 18. How it works 1.User places emergency call. 2. Location is computed on-device using Fused Location Provider 3. Location sent directly from device to operator, using MCC/MNC to look up the appropriate endpoint (either HTTPs or Data SMS AML Message ).
- 19. Fundamental Principles 1. Device-Initiated:Location can only be initiated by a user explicitly dialing 112/999. Location is relayed directly from handset to specified endpoint (not visible to Google). 2. Backwards-Compatible: Live on > 99% of existing Android devices (2.3+) via Play Services. No OS or hardware upgrades required.

Editor's Notes
- #15 Purely a public safety interest and not a business one. With faster and more accurate location, we hope to reduce response times and ultimately save lives.
- #18 Goal is for Android to... Facebook and Google Maps are able to get a faster and more accurate location fix than emergency services. Especially when users are indoors. Our goal is to make this accessible
