1 Introduction
The WCM is a self-contained vehicle tracking device that combines GPS location with LTE CAT-M
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 WCM 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 WCM
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 interface 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.
Figure 1 This product is based on the Asiatelco BG96(4G LTECATM
) b
aseband module. Antennas for cellular and GPS are
internal to the device.
