Angle of penetration
The angle at which the transmitted signal hits the wall is very important.
The effective wall thickness – and with it signal attenuation – varies
according to this angle. Signals should be transmitted as directly as
possible through walls. Wall niches should be avoided. Avoid an
undesirable angle of penetration by repositioning the receiver or by using
a repeater.
