12 General information about radio operation
Radio transmission is performed on a non-exclusive transmission
path, which means that there is a possibility of interference occur-
ring. Interference can also be caused by switching operations, elec-
trical motors or defective 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, en-
vironmental factors such as humidity in the vicinity have an
important role to play, as do on-site structural/screening
conditions.
