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. Inter-
ference can also be caused by switching operations, electrical motors or
defective electrical devices.
The transmission range within buildings can differ significantly from
that available in the open air. Besides the transmitting power and the
reception characteristics of the receiver, environmental factors such
as humidity in the vicinity play an important role, as do on-site struc-
tural/screening conditions.
