“…Higher transmission rate of 2DC, compared with Passive Wi-Fi, is due to wide frequency range it occupies. It can operate as ultra-wideband (UWB) radio system [8]. In this paper, we show that the transmission rate higher than 70 Mbps can be achieved with the EBR of 1.7 nJ/bit.…”

“…It enables signal transmission/reception by all the devices laid on the floor, and even on any furniture covered with 2DC sheets. The devices can communicate with low emission power density of −41.3 dBm/MHz [8]. This is significantly lower than the antenna power of conventional ZigBee devices, which is 0-+20 dBm in a 2-MHz channel bandwidth.…”

Low power communication systems such as ZigBee enable battery-driven sensor nodes in wireless sensor networks (WSNs). Recent growing demand for transferring large amount of data across a WSN requires more energy-efficient communication schemes. Energy efficiency, evaluated in terms of energy-per-bit rate (EBR), determines the upper bound of information quantity that can be transferred while consuming all the energy stored in a battery embedded in each sensor node. TransferJet is one of the most energy efficient wireless communication schemes. It achieves 2-3 orders of magnitude lower EBR than ZigBee, at the expense of very short communication range up to a few centimeters. In this paper, we report on a preliminary experiment of energy efficient signal transmission using TransferJet devices on two-dimensional communication (2DC) system. It worked at reasonably high transmission rate of 71 Mbps with 1.7-nJ/bit EBR. We also explain the feasibility of a room-scale high-speed communication system with such a low EBR based on 2DC technology.

“…2(a). The mesh pitch (period) is 4 mm and the conductor line width is 1 mm, the same as the sheet used in [2]. From the simulation result, the effective sheet reactance of the mesh was determined as X % 9:8 Ω/sq.…”

“…The most dominant signal path is not an aerial radiation but consists of a near-field coupling between the sheet and coupler and of the sheet guided mode. Therefore unwanted RF radiation from the system can be reduced and 2DC enables lowemission ultra-wideband (UWB) high-speed communication [2] and safe wireless power transmission [3]. For appropriate design minimizing RF radiation from the sheet, an analysis model of the radiation is desired.…”

Radiation from surface of two-dimensional communication sheet

Two-dimensional communication (2DC) is a wireless communication system using a waveguide sheet as a radio frequency (RF) signal transmission medium. This paper proposes a theoretical analysis model of RF radiation from a 2DC sheet surface. Previous works supposed that only a non-radiative guided mode propagates along a 2DC sheet and that radiation is due only to open ends of the sheet or to impedance discontinuities around the sheet edges. The proposed model based on field equivalence principle clarifies that the sheet guided mode propagating in a finite-size sheet inherently generates radiation fields even if no edge radiation nor impedance discontinuity are involved.
