This section allows configuring the following parameters (options availability depends
on model):
ATPC – Automatic Transmit Power Control adjusts transmitter output power of
the local system based on the varying signal level at the remote receiver.
Note that ATPC support depends on product’s specs and SW release.
ATPC allows the transmitter to operate at less than maximum power for most of the
time and when fading conditions occur, transmit power will be increased as needed
until the maximum configured value is reached. ATPC messages are carried over the
radio over radio communication channel.
The purpose of ATPC is a) to reduce interference to other radios operation in the
same channel/band and to allow better frequency reuse; and b) to reduce
transmitter power consumption and prolong system’s components life.
ATPC is supplementary to adaptive modulation and works before adaptive
modulation changes modulation profiles.
Interference avoidance algorithm is implemented in order to overcome the main
drawback of use of ATPC: interference from other links that may degrade the radio
link performance. Besides setting the Target RSSI, the user can also set the Target
Note:
When changing Radio parameters of the link (like Mode, frequency…) the link will go
down and come up within couple of minutes.
