gateway should be as free from barriers as possible.
The signal strength is slightly to severely affected by concrete walls, metal shields, enclosures and hilly landscapes.
■
For the best possible transmission power of the antenna, no metal objects, such as pipelines, may be closer than
■
10 cm [3.93 in] to the antenna.
