Abstract: The disclosure relates to techniques to increase the range over which magnetic field induction can be used to communicate data between a transmitting antenna and a receiving antenna. In particular, a transceiver may comprise an antenna configured to transmit a signal via magnetic field induction, a transmit section having an amplifier, a capacitance, and a resistance arranged to form a parallel resonant circuit, and a processing unit configured to generate the signal transmitted via the antenna and to use a spreading code to modulate the signal to be transmitted via the antenna.

Abstract: According to various aspects and technical advantages, an apparatus for electronic shelf labels includes a controller circuit for communicating with communication devices using a contactless communication protocol, a set of two or more antenna coils, each antenna coil located at a known position relative to the controller circuit, and a switch for selectively coupling the controller circuit to one or more of the set of antenna coils. The controller circuit is configured to determine a physical location of a communication device based on which antenna coil from the set of antenna coils the communication device is using to communicate with the controller circuit

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communications device transmits a first set of symbols of a plurality of symbols of a data stream using a first set of constellation points of a pi/N-based modulation scheme, and transmits a second set of symbols of the plurality of symbols using a second set of constellation points of the pi/N-based modulation scheme, wherein each of the first set of constellation points and the second set of constellation points consists of M constellation points, wherein the second set of constellation points is rotated from the first set of constellation points by pi/N, wherein symbols of the first set of symbols alternate with symbols of the second set of symbols, and wherein M is greater than 8.

Abstract: Use of a Near Ultra-low Energy Field (NULEF) communications as a non-radiating means of gaining entry to a car when the car owner is near the car or touching the car body avoids the use of problematic radio signals that may be intercepted by thieves. In addition, a NULEF communications system may be used as a high bandwidth in-car communication system using either NULEF-E or NULEF-H.

Abstract: Techniques to enable near field communication using electric field (E-field) are proposed. When the wavelength of a signal is long relative to the human body, the human body can behave as a conductive hollow cylinder. By capacitively coupling the human body with a transmitter and/or a receiver, the human body itself can be used as a communication medium.

Abstract: Various aspects described herein relate to techniques and modulation schemes used in near-field communications systems. A method for near-field communications is provided that may include receiving a signal including an unmodulated carrier frequency, locking onto the unmodulated carrier frequency, and recovering a data clock frequency from the unmodulated carrier frequency based on a relationship between the data clock frequency and the unmodulated carrier frequency.
