<p>The present invention relates to a system and method allowing a first electronic device to transfer data to a second electronic device using an active phone line when the first electronic device is located beyond a physical location of the active phone line. In one embodiment of the present invention a first electronic device is connected to the extension unit, while a second electronic device is connected to the base unit through an active phone line. The base unit communicates with the extension unit using power lines and/or over-the-air signals using frequency-hopping spread spectrum based on an evaluation of the channels within the power lines and/or the over-the-air signals.</p>
