Since the U.S. Federal Communications Commission (FCC) limits Wi-Fi transmitter power, it’s often necessary to increase the range of Wi-Fi signals using some signal boosting/extending technology. But transmit power is only half of the equation. Wi-Fi connections are always bidirectional and symmetrical. When working to extend Wi-Fi signals, the bidirectional nature of the connection is […]
