NEGATIVE TX POWER VALUE IN TP-LINK EAP110 OUTDOOR
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I set TX power to 20 in setting but using OMADA networking tool and other network analyzer, it is showing negative twenty (-20dbm) with the access point very close and not more than 30cm distance. This make my signal very weak.
1. Is this normal?
2. Does 20 Tx power in setting means negative?
-20dbm is very strong, if you had +20dbm you would have been burned. the settings in the access point are transmitter power in combination with antenna, not sure how it works. there are rules on how strong an access point can send. then it is the power and dbm in the antenna that determine.
so -20dbm is probably as strong as it is theoretically possible to get from an access point when you are right next to it.
Here is an overview of recommended signal strengths.
