Hi,

tpc min 11 dBm
channel 36 power shows level 3 ( 5 dBm)
why does it go below tpc min

Thanks

[pieterh]

are you sure about the numbers?

my guess is it will show -11dBm and -5dBm (beware the minus sign) 

so -5 is higher level than -11 not below

Regards

Hi

tpc

Maximum Power Level Assignment(-10 to 30 dBm) = 16

Minimum Power Level Assignment(-10 to 30 dBm)= 11

UNII 1 UNII 2 / 3

1 = 11 dBm / 12.5 mW 1 = 17 dBm / 50mW
2 = 8 dBm / 6.25 mW 2 = 14 dBm / 25 mW
3 = 5 dBm / 3 mW 3 = 11 dBm / 12.5 mW
4 = 2 dBm / 1.5 mW 4 = 8 dBm / 6.25 dBm

802.11a/n/ac radios
apname baseradio mac channel power level
test 36 3(*)

As per the tpc value the power should be in between 11 and 16
Correct ?

Thanks

Should never go below the mix to power you have set. The question is, you using RF-Profile or using global settings. The RF-Profile defined in an AP Group will override the global setting but if all your AP's are in the default group or AP Group is using RF-Profile of none, then the global is used.

Hi,

Wlc is 5760 , there is no rf profile feature 

Thanks

Well then, open a TAC case...Converged access never worked as well as AireOS and thus why it's going end of sale.

Hi Scott,

This could be regulatory domain  power limit  ? 

Thanks

[Scott Fella · Accepted solution]

Regulatory domain ensure the max allowed.  Min TX has nothing to do with that as this settInc tells the controller not to ever go below this TX power level.  This goes for the Mac TX also, but now the regulatory max TX comes into play. Your AP will not be able to transmit higher than what it is allowed by the regulatory setting for max power.

Hi,

"Should never go below the mix to power you have set.

max  power ?
