Technical features
GPSA technology uses the following elements to function effectively:
"button" that allows you to share your location with a mobile phone via bluetooth connection;
mobile phone connected to a bluetooth device that allows you to share the transmitted information with the police through a special application;
the police as the authority to decide whether an alleged crime should be stopped by its officers or information should be transmitted to FEMA in order to disseminate the location of the alleged victim to all mobile device users in a given area through Wireless Emergency Alerts (WEA).

This technological chain is designed to work without the need to connect to the Internet and use a mobile device at the time of the alleged crime. It relies only on GPS and bluetooth technologies.

To prevent cases with GPS vulnerabilities it is suggested to use Bluetooth and mobile application to send location to police.
