uses a proprietary technique to reduce noise interference while picking up and transmitting data signals.
works with both shielded and unshielded twisted-pair copper cabling, is small enough to fit on laptop PC internal adapters,

Mike Watson rediscovers inductance, and the inductive tap. Film at 11.
Don't be so dismissive. There is something interesting going on here, even if it's not very complex. This thing works with _shielded_ pair. With twisted pair to begin with, you largely attenuate the inductive signal. (A very short lesson in physics: Current generates magnetic fields. Opposite travelling currents generate cancelling fields. Fields do not completely cancel because the wires are not in exactly the same place.) Shielding a twisted pair further attenuates a signal. It sounds to me like it's an inductive tap with some sort of phase locking built into it. By the mentioning networks, it indicates to me a digital signal. I doubt this thing would tap a POTS line carrying voice. Eric
