3.3.1 Truck and Trailer
Usage in Automobiles
Usage in trailers of trucks where walls are made from metallic material can cause signal strength to be reduced. In case of low signal strength, placement of wireless loggers can be changed and moved closer to openings such as doors, windows etc. Antennas with more gain can be used to increase signal quality. Extension cables and cable mounts can be used to place antennas in optimal locations for better signal quality.

Occluding Objects
Occluding objects will affect the signal quality between wireless logger and transceiver. The effect varies by the size, placement and material of the object.
To get the best signal quality, placement of wireless loggers and transceivers should be such that as few objects are occluding the path between wireless logger and transceiver as possible. Table 2 shows the relative effect on signal quality for different materials.
