Research and Development Team: Assaad Chmait, Brian Hebert, Dimitris Kiamilis, Jean Mouradian, Ekaterina SadomovaSupervisor: Dr. Anjali AgarwalCoordinator: Dr. Chunyan Wang & Dr. Amir G. Aghdam

Objective:- To provide a solution for users requiring remote car starting and alarm monitoring services over greater distances than conventional direct RF communication.

- To empower the user with full monitoring capabilites without the need for a 3rd party service provider.

Features:- Rapid user notification in the event of an alarm scenario.- Range of use expanded to GSM network coverage area.- Custom GUI available for SmartPhones.- Works with existing SMS technology.- Real time vehicle tracking and locating through the use of GPS.
