1 Introduction
The Arrow-L is a self-Contained vehicle tracking device that combines GPS location with
WCDMA/LTE connectivity.
The Arrow-L appears to a user or a server application as a single endpoint device. It can be
queried, updated and configured either through a serial connection, or an over the air LTE or
WCDMA IP connection, or through SMS messaging. The Arrow-L presents itself over these
connections as an enhanced cellular modem with attached functional elements. These
elements include:
GPS location engine
General Purpose Bidirectional I/O (GPIO) pins
Relay drive pin output
Serial UART port
Input voltage monitor (optional)
Watchdog lockup protection
Access to these elements and general purpose interfaces is done through an extended AT
command set as defined herein.
Application scene:
This product will be designed based on the MDM9207-1 baseband chipset, which includes
LTE Cat.1, WCDMA, and GPS functionality. The device will use one multi-band antenna and
one dedicated GPS antenna.
