3.4 Bidirectional radio system
The term bidirectional radio system means the transmission
of radio signals to radio receivers and the response option
for the radio receivers to the transmitter. The radio signal
can be sent directly to the target receiver. If this is not pos-
sible, the radio signal will be routed via other bidirectional
participants until it reaches the target receiver. The target
receiver carries out the command and sends a confirmation
back to the transmitter. The prerequisite for a bidirectional
radio system is hence the radio transmitting capability as
well as the radio reception capability of all participating
components.
3.5 Unidirectional radio system
A unidirectional radio system transmits radio signals to radio
receivers. However, unlike in a bidirectional radio system,
the radio receiver cannot send any message back to the
transmitter. It is also not possible to transmit radio signals
from radio receiver to radio receiver.
