Range reduction:
■
On their way between transmitter and receiver,
WLAN signals are damped, e.g. by air or when pen-
etrating walls.
■
WLAN signals are reflected by metallic objects e.g.
reinforcements in walls, metal foil of thermal insula-
tion and thermal glazing with metallised thermal
vapour deposit.
■
WLAN signals are isolated by service ducts and lift
shafts.
■
WLAN signals suffer interference from appliances
that also operate with high frequency signals,
such as computers, audio and video systems, wire-
less signals, electrical transformers and pre-ballast.
Distance to such appliances: minimum 2 m.
