In an emergency, a call to “9-1-1” from any telephone will link the caller to an emergency dispatch center, also known as a public-safety answering point (PSAP). Following a call for help, telecommunicators with help from computer-aided dispatch dispatch (CAD) technology dispatch police, firefighters and/or paramedics with the appropriate measured response.

In approximately 96 percent of the U.S., the enhanced 9-1-1 system automatically pairs caller numbers with a physical address. Approximately 80 percent of 911 calls in 2018 come from mobile devices, but outdated, landline-era infrastructure often makes it difficult for 911 centers to quickly and accurately obtain a mobile caller’s location. To address this challenge, Apple launched HELO (Hybridized Emergency Location) in 2015, which estimates a mobile 911 caller’s location using cell towers and on-device data sources like GPS and WiFi Access Points.

Since June 2018, Apple started using emergency technology company RapidSOS’s Internet Protocol-based data pipeline. The technology quickly and securely shares HELO location data with 911 centers, improving response time when lives and property are at risk. RapidSOS’s system will deliver the emergency location data of iOS users by integrating with many 911 centers’ existing software, which rely on industry-standard protocols.
