CHAPTER 3. VEHICLE INSTALLATION 19
Moovbox
The Moovbox should be installed in a location where its safe from unwanted casual
tampering yet accessible for servicing. This can vary considerably between different
types of vehicle. In a car probably the best location is in the boot/trunk. However in
larger commercial vehicles finding the right spot will depend on the specific design
of the interior. Figure 3.1 shows a Moovbox installed in a coach, behind the cowling
between the driver’s seat and the passenger door. In this example, the unit has been
riveted into place using the four tabs on the underside of the Moovbox enclosure.
Power Source
In most permanent installations it’s best to run power directly to the 12-36VDC power
input on the Moovbox device. Alternatively, 100-240VAC power can be supplied to
the optional PoE unit and then run to the Moovbox over Ethernet cabling. If you plan
to move your Moovbox between vehicles on a regular basis, you can use the optional
cigarette 12VDC adapter; this is particularly useful in vehicles that have 12V power
points in the boot/trunk.
Tip: Consider inserting an on/off switch inline with the power supply so that you can
power cycle the Moovbox independently of the main ignition. This is useful if you
need to turn off the device for whatever reason without stopping the vehicle’s engine.
Wi-Fi antenna
The 3dBi Wi-Fi antenna supplied with the Moovbox provides enough gain to fill many
private and commercial vehicles from cars to single/double decker coaches. How-
ever as vehicles begin to fill with passengers their bodies will attenuate the Wi-Fi
signal. Before you commit to a permanent position, test your Wi-Fi coverage with
a full vehicle. If the coverage is not 100% available throughout, even at a medium
signal strength then consider using a directional antenna instead. Figure 3.2 shows
an installation on a double decker coach; a patch antenna at the rear of the upper
deck radiates the Wi-Fi signal forward and downwards, providing good coverage both
upstairs and down, even with a full load of passengers.
Tip: Make sure you factor the signal loss of the cabling between the Moovbox and
antenna when planning your antenna position. You can help compensate for this loss
