Panasonic Develops World's First*1 Near Field Communication Technology Using Wavelet OFDM

Panasonic Corporation today announced that it has developed a secure near field communication technology (hereinafter, "PaWalet Link") using a loop antenna by applying Wavelet OFDM*2 to a communication method using a magnetic field. As a result, it is possible to limit the communication range from a few millimeters to tens of centimeters. This technology can easily control the communication range by controlling the size of the loop antenna and the transmission power of the communication device. In addition, you can limit the frequency used by selecting the mode/channel.
