This is Basic knowledge if you are working with wireless systems


This means that the Wireless Card will send
25 dbm @ 6 MBit
And only
20 dBm @ 54 MBit
This is normal for WiFi Equipment

The Part with the -96 dB says that the connection with 6 MBit is possible until you are under -96db
With -97 dB you are losing connection

With -81 dB or better you get 54 MBit under -81 dB it starts to go to 48MBit
