Installation recommendations

The gateway must be installed in a location where the radio signal
allows for using the 4G LTE/UMTS/GSM system.

It is advisable to leave plenty of space around the gateway for
maintenance operations.

Do not install the gateway outdoors, since it lacks protection devices
against weather conditions that can damage the gateway (water,
humidity, etc.).

Do not install the gateway near electronic (radio or TV sets, Personal
Computers, wired radio systems, etc.) or magnetic devices that could be
subjected to RF interference from the module: recommended distance
from the antenna is min. 2,5 m.

Do not install the gateway near medical devices. Its operation may cause
damage to hearing aids or pacemakers.

Always make sure that the device operation is permitted in the place of
installation (e.g. installation is not allowed in hospitals, airplanes, etc.).
