Power-over-Ethernet: IEEE 802.3af Draft

Posted by Hemos on from the like-ma-no-extra-wires dept.

SkewlD00d writes "Want power (~10W) and your fat 10/100Mbps pipe (1Gbps maybe) on the SAME jack. Surf the web and recharge your handheld w/o finding its clunky base/transformer, home automation, and control systems are just some of the possibilities. Using suitable hubs/switches or dongle, power can be provided over unused pairs, or possibly raise the signal offset above DC, X10-style (no link, u know why). See IEEE 802.3af DTE Power via MDI Task Force. Maxim (not that one :o) already has some goodies. They have schematics for 8.25W/12.5W single-output and 14.2W triple-output 802.3af PSU. Try FindChips if you're looking for them; they're in production and are NOT vapor-ware!"

    If they just made it a little thinner and lighter, we could have wire Remote Control Airplanes! Or even Boats!

    We have always had trouble using power lines for sending and receiving data not beacuse it is impossible but because our current power lines were never designed to carry data.

    Imagine a merging of the current ethernet and power line standards, you could potentially solve the last mile problem and and at the same time open up new backbones.
