General information about radio
operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possibil-
ity of interference occurring. Interference can also be
caused by switching operations, electrical motors or de-
fective electrical devices.
The range of transmission within buildings can differ
greatly from that available in the open air. Besides the
transmitting power and the reception characteristics
of the receiver, environmental factors such as hu-
midity in the vicinity have an important role to play, as
do on-site structural/screening conditions.
