Rohm's WirelessPowerTransmission system also allows you to charge or power devices by placing them anywhere on the pad, rather than directly over charging positions, and it supports much greater transmission, with one prototype outputting up to 100 watts.
At the other end of the spectrum is the idea of long-range transmission of wirelesspower, which could in principle do away with the need for a charging pad altogether.
The RT-N12HP utilizes a custom hardware architecture that augments wirelesstransmission and signal quality with detachable 9dBi high-gain antennas and a discrete signal power amplifier.
