Power Levels
Follow these steps to set the transmitter power level on
the OU. Refer to table 4 for transmitter power levels.
Step Action
1. Determine the gain of the antenna, A
T
, to be
installed with the OU.
2. Calculate the transmitter power, P
T
, according
to the following formula:
P
T
= 30dBm – (A
T
– 6)/3 dBm
3. Determine the power level to be used in NMS
by consulting table 4.
4. Install a fixed attenuator between the OU and
the antenna if the power level can not be
sufficiently reduced.
5. Set the transmitter power level in NMS.
6. Repeat for both stations.
Example: Determining the transmitted power level.
Step Action
1. Install a 24dBi antenna.
2. Transmitter power level to be used is:
PT = 30 dBm – (24-6)/3 dBm
= 30 dBm – 6 dBm
= 24 dBm
3. Power level 5 corresponds to 24 dBm
transmitter power (from table 4).
4. Set the power level to level 5 in NMS.
