ElectAura-Net

ElectAura-Net is a novel indoor broadband networking and positioning system. A wireless(-like) communication is enabled by electric-fields (electric aura) emanated from the human body and the floor. The result: the world's first broadband (10Mbps) intrabody communication. ElectAura-Net also provides indoor positioning, which is urgently needed for "ubiquitous" communication.

Innovation
ElectAura-Net provides both broadband wireless(-like) networks and a meter-accuracy positioning system for indoor use. It is a kind of "intrabody communication" system that uses electric fields as transmission media, and the human body and floor as an Ethernet cable. In this system, a "communication-cell" (carpet size) can be shrunk down to one meter or less, and simultaneous access by many users can be realized. Ordinary intrabody communication systems cannot achieve long-distance communication between components such as body-worn devices and the floor. ElectAura-Net provides extra-high-sensitivity and high-speed capability.

Vision
The ElectAura-Net team is developing a miniaturized and higher-speed intrabody communication system. They are also developing a large-scale floor network with automatic map generation to realize a "ubiquitous" communication system in which people and objects are connected by just standing on a carpet.

Goals
There are great expectations for "ubiquitous communication" in which everyone and all objects are always connected to the network. Outdoors, we can use cellular-data networks and GPS systems. But so far, there is no effective solution for indoor situations. ElectAura-Net overcomes the indoor limitations by providing easy-to-use, high-speed access to the network and accurate, reliable positioning.
