The firmware in the device applies intelligent filtering to overcome coverage
limitations for both GPS and GSM/GPRS networks. Motion sensor controls the status
of the device, whether in sleep, idle or fully-powered mode, and thereby controls the
amount of current consumed by the device. The device supports over-the-air firmware
upgrade to deliver additional functionality without physically touching the device once
installed.
