ElectAura-Net, a 10-Mbit/second Body Network 126

Roland Piquepaille writes "In 'Human Body Network Gets Fast,' Technology Research News tells us that NTT Docomo researchers in Japan have created a 10-Mbit/second indoor network by using human bodies as Ethernet cables. 'The network, dubbed ElectAura-Net, is wireless, but instead of using radio waves, infrared light, or microwaves to transmit information it uses a combination of the electric field that emanates from humans and a similar field emanating from special floor tiles.' ElectAura-Net is faster than the Bluetooth radio wave system and provides a solution for indoor networks. The researchers think that this is a solution for "ubiquitous" communication, using GPS outdoor and our bodies indoor. This summary contains more details."

  • ..but how much does this cost? If you have to put special flooring down and cover the entire area of a room, the cost of the system and the floor material is going to be high. The first use will probably appear in convention centers/meeting rooms so everyone can link their laptops and palm pilots at 10Mb/s.
    • ... but typically, meeting rooms and convention centers are carpeted. Would you want to get special (probably somewhat expensive) tile (and forego the comfort/looks of carpet) just so people can use this funky new network when there are alternatives already available?

      • I have not read the article, and am kicking myself, but I will as soon as I post this. I doubt carpet would play into this, as there are not too many metalic soled shoes, and thust it would have to work off of some sort of induction, instead of a direct connection. Thus carpet would perform just as well as tile. Assuming you do not have a carpet made of copper threads with gaps smaller then 27cm (2.4ghz wavelenth? are they using 2.4ghz?) I could be way wrong, but I would bet it could be done with many floor

In a crowded space you could solve many of the range problems that less powerful wireless technologies like bluetooth have, obstacles(as long as they were humans) would actually improve the range.

      I was thinking the same thing. I can't imagine that it would be good for you. Electricity and magnetism are interrelated; if you push one, the other bobbles.

      Normally your body produces a magnetic field due to the small amount of electricity your nerves generate. If you start modulating that field externally, you ABSOLUTELY are going to have some kind of an effect on the current flows in the body.

      It's possible the signal may be modulated at too high a rate for the nervous system to detect, but I persona

    Geeks do not touch one another. Encouraging them to do so for the sake of increased bandwidth will simply confuse them, and probably cause more than a few nervous breakdowns (of course, that assumes that having your bioelectric field modulated at 10MHz won't do that anyway).

I remember someone a while back trying to give people wristbands that would track vitals and transfer them to a computer to control the music at a niteclub. Something like this floor could be used as a voting system to automatically determine whether the crowd at a club or party likes the music or not based on the number of "connections" on the dancefloor. It could also rate the music or any other live entertainment for t

      Basically an LPS would be way out of our scope, a wristband would give problems as well: it needs power and electronics, but has to be light and portable.

      We settled for turning the dancefloor into a giant, fast responding

    • Geeks can run the club, but real people (e.g. non geeks actually go to clubs). Its a novel idea actually. Trance, House, Electronica or some other version of music is played. People then dance to the beat on the dancefloor. Sometimes so many people show up and so many dance that the temperature on the dancefloor actually outpaces the air conditioning. As a result of this and some chemical reactions in the bodies of the people dancing, heat is given off and sweat is produced. So some people task themse

    We need to learn how to judge these systems. It takes years to develop and deploy a technology like this, and after you do, it would be very nice if it could be stretched for years to come. 10 MBaud might sound nice now, especially if its a real 10 MB unlike WiFi, but will it meet the need 5 years from now? At least some of the energies of the industry need to be focusing on how to get residential baud rates back onto a long term Moore's law-like development curve without killing us with new home or community infrastructure rollouts every few years.

    A good wireless fit into the home network should aim itself to eliminating the mass of cables behind my entertainment center and making it possible to have many high fidelity video bandwidth devices that can be easily moved around without concern about the cost of fishing new cables. To match it to existing hardware, it probably should aim at IEEE 1394 per device speeds. If a small module were available to convert IEEE 1394 ports or USB 2 ports to the new backbone, many devices would be hostable on the home's network today. In order to host a large number of devices, preferably multiple security cameras, multiple LCDs or projectors, multiple speaker systems, etc, I suspect that this means that it should be a cellular network with a fiber backbone and cells that are room sized. It might actually be beneficial if the signal could not easily penetrate walls. The fiber backbone should use a type and quantity of fiber that we know can satisfy needs for about 20 years (approximately 11 Moore's generations) so that we can just upgrade the cells without fishing the walls again. The cell stations should be easily swappable, overpowered (for growth) modules. They should be placed so that if a future generation decided to use a spread spectrum light solution along with the RF for backwards compatibility, their placement would support it. The modules should be designed with the expectation of a 3 year lifetime before the owner would want to upgrade at least some of the rooms. Hopefully, with the range limited to rooms, the size and amount of power of the mobile side could be kept down.

    Why would we need this kind of switched bandwidth? The only answer a geek should need is, if you build the infrastructure, the need will come. My personal desire would be to gradually turn my home into a lab that is ubiquitously connected so that I can start experimenting with using electronics as a means to bridge gaps, not just between man and computer, but between people and also to start using electronics to ease more of the mundane tasks of life and increase quality of life rather than for pure entertainment.

    One aspect in particular that could have prevented the last several deaths/major disabilities in my family would be continuous medical monitoring and analysis. Detecting heart attacks and strokes at an early stage through continuous monitoring so that the benefits of existing treatments that must be administered in a timely fashion can be fully realized could save or preserve the quality of over a million lives a year in the US alone.

    Yes, systems like that exist, but deployment is too selective and too expensive. If we build out the infrastructure and sensor networks as a multiuse system, the only part that has to come from the medical industry would be the software. And I suspect they couldn't keep the open source community out of that as long as it is served from countries that don't regulate equipment and software intended for medical use.

    • Just did a little calculation and figure, if you plan on 10 (a few TVs and cameras + many lower bandwidth channels for audio in every room) simultaneous 480MBaud channels (good match for either Firewire or USB 2.0) as a starting point, the home's fiber bundle backbone should be constructed with materials and numbers of fibers that allow for a theoretical limit of around 10 TBaud in order to be capable of following Moore's law for 20 years.

  • Well, human bodies do work as antennas, as anyone (old) who has ever grabbed TV rabbit ears knows. So, I suppose this is not beyond the bounds of possibility. It would likely be pretty short range though, especially with the bandwidth claimed. More bandwidth = more energy, and we can't have people getting electric shocks walking around the floor! The above also makes me wonder about the effect of shoe thickness - being that this was in japan, were the users wearing shoes?
