Overview The LiveLink 4 is a battery-backed vehicle tracking and telematics unit utilising GPS, GSM / GPRS, BLE and Wi-Fi technology.

Installation LiveLink 4 units are designed to be installed both within the vehicle cab in a protected environment and externally fitted. Depending on the application the device may be permanently powered, or only powered periodically. In either application, the LiveLink 4 is designed to make efficient use of the power available through the use of sleep modes when there is no activity.

Description of operation Providing external power is applied, or the internal battery is sufficiently charged, and the unit is within GPS and GPRS coverage the unit will periodically (based on time and/or distance, and configuration) transmit location and telematics information to the relevant Microlise system. If out of GPRS coverage then messages are stored into non-volatile Flash memory for transmission later when a GPRS connection can be established.
