Note : Connector pinout could vary depending on the selected option (refer to chapter1 description).
3.2.4.7 - Configuring the Automatic Transmit Power Control (ATPC).
ATPC is a process which is used to limit transmit power to the minimum necessary while having a
good transmission. When ATPC is selected for equipments in a network working in the same
frequency band, it allows to increase density and frequency re-use.
ATPC must not be active during antenna alignment process.
ATPC settings depend on the structure of the network (frequency re-use, interferers, link margin).
The operator has to define three main parameters :
• Maximum ATPC transmit power
• Minimum ATPC transmit power
• ATPC receiver threshold
Minimum and maximum ATPC transmit powers must be within transmitter power range, and
Maximum ATPC Transmit power – Minimum ATPC Transmit Power ≤ 20 dB.
ATPC threshold must be within –50 dBm to –80 dBm range.
The ATPC process consists of reducing transmit power as low as possible within the specified
range, without having errors on the remote end, and without having a remote receive level lower
than the ATPC threshold.
To activate ATPC click on the ATPC button on main Pilot screen. The ATPC button indication is
"ON" when ATPC works, or "OFF" when ATPC is disabled.
To configure ATPC, use the menu Tools/Config Tools/ATPC/ Local (or Remote)
