1 Introduction The Arrow-L is a self-Contained vehicle tracking device that combines GPS location with 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 IP connection, or through SMS messaging. The Arrow-L presents itself over these connections as an enhanced cellular modem with attached functional elements.
2 Hardware Design 2.1 Basic Hardware Items Requirement Baseband Chipset RF Transceiver Memory Air Interface Frequency Antenna GPS Antenna Interface MDM9207-1 WTR2965 MCP_NAND 2Gb / mobile DDR2 1Gb Support for LTE Cat.
LED’s Two LED status indicators are provided to verify correct installation and operation. UART A UART port is provided for AT command and data interaction and optionally for application specific control. Relay Driver A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil intended to interrupt the starter solenoid relay for the ignition circuit to a car.
Tracking Time Requirement 2.3 Reacquisition: -153dBm Acquisition: -144dBm Acquisition time: Hot: <2s Warm: <15s Cold: <60s Reacquisition: 2s - 10s Depends on signal level Certification and Safety Items Requirement Drop Design 0.
