Setting the sector’s transmit power
This procedure explains how to calibrate the sector’s power transmission level using the results of the power
loss measurements taken in the previous procedure.
Requirements
• A CLI session to the IP-RN 8000
• The average dB loss for the sector calculated in the previous procedure
Procedure
1. Calculate the power loss parameter for the CLI command using the average power loss from the
previous procedure as follows:
a. Subtract the power loss of the power splitter and attenuator.
b. Round the result off to the nearest 1/8th (to the nearest 0.125)
For example, if the average dB power loss was 33.55 dB and the power splitter and attenuator have a
combined loss of 32 dB:
a. 33.55 — 32 = 1.55
b. 1.55 rounded to the nearest 1/8th is 1.625
So, the result is 1.625. This result is used in the next step.
2. Turn off the sector as follows:
AIRVANA-03>enable
AIRVANA-03#configure
AIRVANA-03(config)#sector-element element1/4/1
Use element1/4/2 for sector 2/beta and element1/4/3 for sector 3/gamma
AIRVANA-03(config-element)#shutdown
3. Set the transmit power level for the sector as follows:
AIRVANA-03(config-element)#pa-offset +1.625
Where +1.625 is the result calculated in step 1
4. Turn on the sector as follows:
AIRVANA-03(config-element)#no shutdown
AIRVANA-03(config-element)#exit
AIRVANA-03(config)#exit
AIRVANA-03#exit
This procedure is complete. Go to Verifying the sector’s power level
