12 General information about radio
operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possi-
bility 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
vicinity have an important role to play, as do
on-site structural/screening conditions.
If "secure transmission" (AES) is activated for
the switch actuator, this implies:
•
increased volume of communication traffic
• actuator groups are unable to execute commands
simultaneously.
