11 General information about
radio operation
Radio transmission is performed on
a non-exclusive transmission path,
which means that there is a possibility
of interference occurring. Interference
can also be caused by switching ope-
rations, electrical motors or defective
electrical devices.
The range of transmission within
buildings can differ greatly from
that available in the open air. Besi-
des the transmitting power and
the reception characteristics of
the receiver, environmental fac-
tors such as humidity in the vicini-
ty have an important role to play,
as do on-site structural/screening
conditions.
