What is the difference between Proximity-based Contact Tracing (sometimes referred to as BLE Contact Tracing) and Location-based Contact Tracing?


Proximity-based Contact Tracing enables organizations to detect and alert their members of exposures to COVID-19 by using Bluetooth Low Energy (BLE) to enable exposure proximity functionality through the use of BLE keys. These BLE keys will detect exposure to another individual up to six feet away and within 15 minutes of exposure. Because Proximity-based Contact Tracing utilizes BLE, it is sometimes referred to as BLE Contact Tracing.

Location-based Contact Tracing looks at calendars, badging, Wi-Fi, travel itineraries, etc. to detect exposure.

Location-based Contact Tracing is available in the corporate Everbridge Mobile App on both Apple iOS and Google Android. Proximity-based Contact Tracing is also available in the corporate Everbridge Mobile App for Google Android. To have Proximity-based Contact Tracing on the Apple iOS, an additional Mobile App is required called Everbridge Contact Tracer App for iOS (EVBG CT iOS).
