A low power and high speed data transmission system based on 2D communication

Abstract

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.
