EIRP queries

Hi Team,

 

I have set EIRP as 6 and 12 in g radio profile. In arm, it is as below:

 

Min Tx EIRP                                                                  15 dBm
Max Tx EIRP                                                                  18 dBm
 
However, when I check show ap active, it shows that AP is using 15dBm as EIRP.
 
EIRP in radio profile is considered, is that correct? Why is the AP using 15 dBm? There is no ap specific config.
 
Any help would be highly appreciated.

Re: EIRP queries

Nobody disables ARM.  If you did disable ARM, all access points would be the same transmit power and channel in the radio profile.

 

Unless you are running an MM, the Min and Max TX in the ARM profile decides what the transmit power range for the access point is when ARM is enabled.

Re: EIRP queries

ARM must be taking over. Have you created a test radio profile with ARM disabled?

Re: EIRP queries

Hi,

 

Thank you for your response. ARM is enabled so will it take EIRP from radio profile or ARM profile?

Re: EIRP queries

ARM should take over.

Re: EIRP queries

Hi,

 

Thank you for your quick response. May I know what is the use of EIRP in radio profile.

 

ARM enabled and arm profile says Max Tx EIRP.

 

Min Tx EIRP 15 dBm
Max Tx EIRP 18 dBm

 

Radio profile is as below:

 

Min EIRP 6 dBm
Max EIRP 12 dBm

 

In show ap active, it shows AP is using current EIRP as 15, is that correct? I thought it will use EIRP in radio profile which ranges between 6 to 12 dBm.

May I know what is the use of EIRP in radio profile.

Re: EIRP queries

What version of ArubaOS are you running?  6.x or 8.x?  If you are running 8.x, do you have an MM?

 

If you are running anything without an MM, the AP uses ARM min tx and ARM max tx by default to determine the AP transmit power.  The radio profile EIRP would be used if the ARM setting was disabled.

 

If you are running 8.x with an MM, the radio profile min and max EIRP is used by Airmatch if you are running an MM in 8.x to determine the AP transmit power.

Re: EIRP queries

Have you tried after disabling ARM?

Re: EIRP queries

Hi Team,

 

Thank you for your response. I have not made any changes. I would like to know the use of it before making any changes.

 

My setup is of standalone.

Re: EIRP queries

The ARM min and Max TX power under the rf dot11a or g profile for the radio would dictate the transmit power of an access point.
