In the chapter Device installation, further guidelines can be found regarding device installation in a challenging environments
Mounting Orientation Orientation
All Controlant equipment can be mounted in any orientation. However, mounting the device according to recommendations may have positive effects on wireless communication range. The default quarter- and half-wave antennas which the Controlant devices come equipped with by-default get the most gain if they are parallel.
...
Table 1: Shows the different orientation of loggers and transceivers and how good each setup is in terms of signal quality.
Environmental factors
Various environmental factors can affect on the communication range of the wireless system. Below is a description of a few issues which can arise when using wireless communication in different environments
Indoor use
Indoor use can reduce the signal strength. If the path between a transceiver and a wireless logger is closed off by walls, the signal strength might be reduced. Signal strength reduction varies, depending on the building material and thickness of walls.
...
The general rule is that the thicker the wall the greater reduction in signal strength. Table 2 shows the relative reduction in signal strength for different building materials. The setup is shown in picture 1.

Wall material | Relative Signal Reduction |
Metallic (Aluminum, iron etc.) | Maximum reduction |
| Concrete with iron binding | Very High reduction |
Concrete | High reduction |
Gypsum | Average reduction |
Plastic/Wood | Low reduction |

Various factors can add to range issues, such as radiation from electronic equipment, other occluding objects, high humidity etc.
While installing the Controlant system, these factors should be taken into account when choosing the optimal location for a transceiver. Controlant offers various accessories to get a better signal quality for the system, including; antennas with different characteristics, antenna extension cables and mounts. By using the accessories, users can place antennas in optimal locations for better signal quality.
