4.6 Recommendations about antenna placement and orientation
Antenna placement rules
• The antennas should be oriented vertically, so perpendicular to the ceiling and parallel to the w alls.
• 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 frequ ency range, e.g. other W i-Fi ac cess
points, cordless telephone, microwave ovens, …. It is also best to install antennas at least 15 cm (6 inches) from concrete walls.
• The mos t favorable s ituation is a direct line of sight between antennas and Buttons. 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
ClickShare users. As a res ult, the advised position for the antennas is at the side of the m eeting room.
