Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1 + 1 ⁄ 2 in) or less. [1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. [2]

The power density of near-field transmissions is extremely restrictive and attenuates or rolls off at a rate proportional to the inverse of the range to the sixth power (1/r 6) or −60 dB per decade. In current commercial implementations of near-field communications, the most commonly used carrier frequency is 13.56 MHz and has a wavelength ...

Near-field electromagnetic ranging is an emerging RTLS technology that employs transmitter tags and one or more receiving units. Operating within a half-wavelength of a receiver, transmitter tags must use relatively low frequencies (less than 30 M Hz) to achieve significant ranging.
