Hi,
I want to know how can i decide my card is either 17 Db 0r 20 db 0r 23 db.
is there any facility in mikrotik router os.
Yes in Tx Power settings.
Hi,
I know but you can change the tx power manually.
that’s the confusion.
Using ROS 3.x:
Set the wireless mode to AP-bridge and activate the radio card so that it is transmitting.
In WinBox: wireless → interfaces → Tx Power
Use the pull-down menu to select Tx Power Mode: default.
If the radio is actually running, you will see the available power levels that the radio is reporting to the router. The radio will only use its maximum power at the minimum speed. As the speed increases, the radio will automatically select a lower power.
Unfortunately, MT can only display what the radio tells it. If the radio reports the wrong data, or the MT device driver does not know how to query the radio properly, the data will be wrong.
Until recently, the results were always wrong for all Ubiquiti cards, with a 10 dBm offset. MT now has special code just for Ubiquiti and adds the 10 dBm back into the display, using parenthesis to show you the values that were actually reported.
I have recently determined that the displayed values are also wrong by about 10 dBm for Engenius 8602+S radio cards. Here is a link to that post: http://forum.mikrotik.com/t/winbox-tx-power-display-seems-10-db-low/22165/1
I don’t know if other radios, especially high power radios, have similar problems.
I hope this helps.
