GT500 is 
a powerful GSM/GPS/WiFi tracker for personal tracking. With superior receiving sensitivity, fast TTFF and Quad band GSM frequencies 850/900/1800/1900MHz, its location can be monitored in real time or periodically reported by a backend server or other device. Based on the embedded @Track protocol the GT500 can communicate with the backend server through the GPRS/GSM/WiFi network to transfer reports of emergency/SOS, Geo-Fence boundary crossings, low battery or scheduled GPS position, cell ID or WiFi access point Mac address among other advanced features. Users can easily to dial preset phone number by using user define button or the SOS button. System Integrators can easily communicate with the GT500 by using the @Track protocol. The WiFi access point Mac address reporting will help of accurate in-door location fix with WiFi access.
