SIGNAL PATH CLEARANCE (FRESNET ZONE)
The Fresnel Zone is the area around the visual line-of-sight that radio waves spread
out into after they leave the antenna. You want a clear line of sight to maintain
signal strength, especially for 5.8 GHz wireless systems.
MULTI-PATH FADING
Because
WAP-ABG2458
typically transmits its strongest signals in a cone-shaped
pattern, some of the signal may be reflected from a nearby building, from water
under the signal path, or from other RF reflectors. This reflected signal can then be
received by the far- end WAP-ABG2458 and superimposed on the main signal,
usually degrading the signal strength.
