General

Challenging installations come in different forms. In general the following may pose challenges during installations

1. The more objects, such as walls, doors, coolers etc., are occluding the direct line of sight between a logger and a gateway, the less wireless signal strength can be expected. 
2. The further away the logger is from the next gateway, the less signal quality.
3. Humidity in the environment. The more humid, the less signal quality.
4. The more devices and machines that emit electromagnetic noise, the more likely they are to affect other wireless devices.

Unless there are specific problems, such as described in chapters "Problems" and "Challenging Environments" below, most issues can be solved by the following methods:

1. Moving logger and gateway closer together.
2. Moving obstacles and/or move logger/gateway to reduce effect of occluding objects between the devices.
3. Try Controlant supported antennas with increased gain to increase signal quality
4. Add a new gateway closer to the logger
5. Aligning antennas of gateways and loggers parallel, as shown in the picture below.

Problems

If logger is close to gateway and, under normal conditions, should communicate with gateway the following issuse might apply.

Challenging environment

In some cases, users want to monitor in spaces where wireless connectivity is hard to ensure. In such cases, different installation methods can be used.
