Power Levels

Follow these steps to set the transmitted power level on

the OU. Refer to table 4 for transmitted power levels.

Step Action

1. Determine the gain of the antenna, A

, to be

installed with the OU.

2. Calculate the transmitted power, P

, according

to the following formula:

= 30dBm – (A

– 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 transmitted power level in NMS.

6. Repeat for both stations.

Example: Determining the transmitted power level.

Step Action

1. Install a 24dBi antenna.

2. Transmitted 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

transmitted power (from table 4).

4. Ste the power level to level 5 in NMS.
