12. 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 operations, electrical 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, environmental factors such as humidity in the vi-
cinity have an important role to play, as do on-site structu-
ral/screening conditions.
