Frequently asked questions
- What is a typical Wi-Fi signal strength in dBm?
- -30 dBm is excellent (very close to the access point). -70 dBm is usable. Below -80 dBm connections become unreliable.
- What is the difference between dBm and dBW?
- Both are logarithmic power units. dBm references 1 mW; dBW references 1 W. dBW = dBm − 30. A 1 W transmitter is 30 dBm or 0 dBW.
