Tips for WiFi™ receive
Common questions about the installation of an WiFi™ router in a flat/house often can not be simple
answered. If the radius of the to covered area small, then mostly the router can be placed anywere,
and the antenna orientation is also second-rate. But if the limits will be used, a few centimeter or a
few degree of the antenna evelation leads to the deciding improvement.
•
If possible, place minimum one antenna in 90° angle to the farest WiFi™ device, because
with this the highest radiation is given
•
If you need a long vertical range, e.g. more floors, it could be helpful to orientate the antenna
horizontal
•
Very bad is a flat angle through ferroconcrete, e.g. the router placed in the first floor lefthand
side, an the receive device placed in the upper floor right hand side
•
Glass has a high attenuation factor to the signal
•
Rig walls also have a high attenuation factor, that is important to consider, if you plan to place
the router in the attic.
•
Make attention to hidden barriers: metal cupboards, wall shutters, metal shelves in the
neighboring room, steel-roolcontainers under the desk: all these objects creates a signal
shadow wich can lead to larger WiFi™ holes.
•
Older cordless phones and older DECT models can massively disturb the WiFi™: In case of
doubt, only a test is helpful: pull the mains plug from the base stations and remove the
batteries from the handsets
•
USB 3.0 devices can cause massive interference in the WiFi™. Directly connected USB 3.0
devices to the router, or also in the immediate vicinity of the router, should be temporarily
disconnected an make a re-test
•
Look for reflections. Mettalic objects directly next to WiFi™ devices can reflect the radiation
and impair the reception quality in the worst case due to interference. Check for a clean
nearby environment
•
Play with the alignment of the antennas (if possible). Move the antennas in 5° increments and
check the signal strength
