Switch On For Powered Data Networks

Posted by ryuzaki0 on from the net-comes-with-free-juice dept.

ReLik writes "The BBC has an article regarding power supply via networks. 'Instead of needing adapters, computer networks could soon be supplying the devices they interconnect with both data and power. Some makers of network equipment are already putting the power via data cable system into their products. The basic plugs for computer networks are the same all over the world, raising the possibility that powered data cables could become a universal back-up power supply.'" We've talked a little about specific 802.3 spec advances previously.

    Both HIGH SPEED/POWER, AND FULL SPEED/POWER... and the as-yet-unreleased LUDICROUS SPEED/POWER.

    This is just another case of the Brits trying to steal our momentum... those bastards.

    The days of travelling with lots of different adapters to ensure you can recharge your laptop, phone and other gadgets could soon be at an end.

    How effective would this in a world striving to move to wireless protocols?!
    It wouldn't get the chance to make a scratch let alone a mark.

  4. Power over ethernet? by pv2b · · Score: 5, Informative
    Yes, power over ethernet (POE) has been possible and been for quite some time, although mostly for powering up wireless base stations...


    Here is some info by POE from NYCWireless...


    Now just give me wireless repeater base stations powered by tesla coils and I'll be in heaven. :-)

  5. What about data over power lines? by Eric(b0mb)Dennis · · Score: 5, Funny

    So.. we have power over data lines and data over power lines..

  6. Re:Power causes interference? by wfberg · · Score: 5, Funny


    Wouldn't supplying substantial amounts of power through network cable (lets say cat5) make enough EMI to scramble the data going through the other pairs?

    Gee, I suppose those boys at the IEEE haven't paid any attention to that. How embarrassing. Those electrical engineers, always chasing the girls, playing in rock-bands, and entering in surfing contests! This kinda thing was bound to happen...

    Check out the prelimary specs for 802.1u - power over wireless ethernet. They are planning on using microwaves to send the data and power to wireless devices around the home and office.
