1 Introduction
The LTE-V and derivatives are self-contained vehicle tracking device that combines GPS
location with LTE CAT1 cellular connectivity. It is primarily a location reporting device that
responds to requests (user, server) and events (timers, geo-fences). Data reports consist of a
single record that contains all location data and system status.
The device comes pre-configured from the factory. It is ready to use. The LTE-V appears to a
user or a server application as an endpoint device. It can be queried, updated and configured
either through a serial connection, an over the air IP connection, or through SMS messaging.
The LTE-V presents itself over these connections as an enhanced cellular modem with attached
functional elements. These elements include:
GPS location engine
Accelerometer
Input/outputs dedicated for ignition, relay, buzzer, and general purpose
Serial UART port
Timers
Watchdog lockup protection
Power management
Event reporting
Voltage monitoring
Access to these elements and general purpose interfaces is done through an extended AT
command set. Configuration parameters are stored to flash memory and are automatically used
on the next power up event. For more details, please reference the AT Command document.
