10 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
dier greatly 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 have an
important role to play, as do on-site structural/
screening conditions.
