1.2 Overview
The purpose of the MARCUS
®
Web application is to track vehicles using a standard Internet
connection. The overall system consists of one or more mobile devices and the Discrete
Wireless Gateway. A tracking device can be easily installed inside any vehicle. The MARCUS
®
Radio Module can also monitor operational status and can collect data from external probes
or sensors through the Sensor Connector. All of this information is transferred to the
Discrete Wireless Gateway
through a wireless communication link. The Discrete Wireless
Gateway
is capable of controlling and monitoring multiple mobile devices. The position data
received from the mobile devices is transferred to the Discrete Wireless Gateway
where it is
displayed on a Geographical Information System (GIS) utilizing mapping technology within
the Internet-based on the MARCUS
®
GPS Fleet Management Application.
1.3 MARCUS
®
3G Radio Module Hardware
The mobile devices are small, can be easily and quickly attached to a vehicle, and will
receive commands, provide GPS position data and status information to the Discrete
Wireless Gateway
via various wireless networks.
The GPS and wireless communication modules require additional antenna. The device is
powered by an external power supply; vehicle power (9-30 volts). The devices are
designed to be installed in the vehicles cab and are capable of surviving and functioning
inside the vehicle. The unit is not waterproof, nor is it designed to be placed near or
on heat generating sources (in the engine compartment, attached to the heater).
