Antennas The SpeedTouch™ features two antennas: one internal and one external. For
transmission of data, the external antenna is always used; whereas for reception of
data, the SpeedTouch™ automatically selects the antenna which receives the optimal
signal.
Direct the external antenna to allow optimization of the wireless link. The antenna
characteristics are such that wireless links perpendicular to the antenna are favoured.
If for example the antenna is erect, wireless links in the horizontal plane are favoured.
Please note that the antenna characteristics are influenced by the environment, that
is by reflections of the radio signal against walls or ceilings. It is advisable to use the
received signal strength as indicated by the wireless client manager to optimize the
antenna position for the link to a given client.
Concrete walls will halve the radio signal strength and thus affect the connection.
