1 Introduction

The LTE

is a self-contained vehicle trackin

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

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

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.
