The antennas should be installed far enough (at least 50cm/1.6ft) from metallic surfaces to avoid
unwanted reflections and far enough (at least 1m/3.3ft) from other radio equipment that operates in the
same frequency range, e.g. other Wi-Fi access points, cordless telephone, microwave ovens,…. It is also
best to install antennas at least 15 cm (6 inches) from concrete walls.
The most favorable situation is a direct line of sight between antennas and Sensor-buttons TOUCH. Any
obstruction will cause the signal to follow a longer propagation path, which can result in performance
degradation.
Due to the particular radio pattern of the dipole antennas, the antennas should not be placed just above
potential positions of Sensor-buttons users. As a result, the advised position for the obstruction antennas
is at the side of the meeting room.
