Enigma and GPRS
The key to Enigma’s Skyline system is a small yet highly powerful module that is installed, often discreetly, in the piece of plant or vehicle that it is to monitor. Known as the Skyline X1 module, the device contains as well as its high sensitivity GPS receiver, a quad-band modem with general packet radio service facilities.
General Packet Radio Service (GPRS), allows constant broadband power that is constantly connected to the monitoring service, and allows for the transmission of data at pre-determined fixed intervals averaging two seconds per transmission. Through utilizing the power of GPRS, the Enigma Skyline X1 module can receive updated positions through the GPS network. This information is stored, monitored and transmitted to the server through the GPRS modem. Even though there is no movement detected, messages are transmitted every five minutes to that effect. The system is capable of detecting and providing a ‘tow-away’ alert, or if the plant’s batteries are being disconnected.
