WiFi Signal (Typical Indoor)

The invisible bubble of connectivity around your router/Computing

A standard WiFi 6 router broadcasts at about 100 milliwatts on the 5 GHz band with a usable indoor range of roughly 35 meters. The signal weakens with every wall it passes through. Your WiFi router is technically a tiny radio station, broadcasting at about 1/10,000th the power of a commercial FM transmitter.
