The witech principle uses the technique of the electromagnetic induction, by which energy gets transmitted wireless in the nearfield from a transmitter to a receiver. There are already solutions on the market for point-to-point-connections for single devices. With the witech principle instead, different devices can be supplied and whole table surfaces can get covered, whereby the position of a device to be supplied doesn't play a role any more for the energy transmission. With the use of this technology problems with annoying cables and the search for a socket for laptops, tablets, lamps, cellphones and other electronic devices are not longer existent anymore.

Therefor the table areas get supplied with a coil array, which is connected with a transmitter unit, which gets placed invisible under or in surfaces. The coils gets powered shortly one after another in the Burstmode. An overlaying receiver gets activated by the small amount of power and communicates with the energy transmitter. The energy transmitter receives the information data and the energy receiver gets supplied very fast with the necessary power, while the efficency of the energy transmission is optimized.
