Abstract
A system and method for instantly summoning assistance to the location of an emergency. A mobile unit providing subscriber communications with an operator or emergency service provider includes a beacon signal generator for directing service providers to the location of the emergency. Subscriber communications are established using an existing personal communication system. The beacon signal generator transmits a wideband spread spectrum that is analyzed at receiving stations to determine the location of the mobile unit.
