Does WiFi Have the Power to Travel Through Walls?

Wi-Fi signals can penetrate walls using radio waves in the frequency range of 2.4GHz or 5GHz. These wavelengths are small enough to pass through cracks and openings in walls. WiFi signals also reflect off objects, allowing the signals to propagate around obstacles. The material the wall is made of impacts WiFi penetration - signals pass more easily through drywall than concrete. In conclusion, with enough transmitting power, WiFi can penetrate walls, but the signal is weakened. Strategic router placement helps maximize WiFi coverage throughout a home.
