Using inductive charging as an internet connection.

Postby Ciber » Thu Jan 16, 2014 9:55 pm UTC

I was thinking earlier today in a course I am taking that has every student using a laptop in the class room. Obviously internet speed is important, and since everyone in a class of like thirty people is connecting to the schools wifi at once we tend to get slowdowns, especially for assignments with youtube videos.

With wifi you have to worry about everyones signals interfering and degrading speed.

So what if embedded something similar to those cool inductive phone chargers into the desks? I figure the range is low enough that you get no interference and you could probably get speeds comparable to actually plugging things in. As a bonus, you could include normal inductive charging so that half the class who are too dumb to charge their stuff overnight do not have to bring bulky charging cords and sit in the back of class where the outlets are.

Or the desk could have an actual Ethernet cable, if practicality trumped cool factor.

well yeah, but then you would have to plug things in, and that adds a moving part.

You'd have to plug the desks in. Or they'd in turn have to be wirelessly connected.

Sure you could in principle increase bandwith for many people in little space, by having a lot of local very short range connections, as you propose, but I don't see it being practical or cheap.

If you already need the wire mess to have the tables hooked up, and you only get internet when the laptop is actually standing on the table, then just make a docking station. It adds a "moving part" but so what? It is easier and cheaper.

...

Okay, for some reason I am beginning to change my mind. If the price could be brought low enough, I could actually see wireless docking stations, both charging and providing high speed connection as soon as the device is placed on the pad.

Docking stations are already wireless for all practical purposes. Sure I have to click my laptop into the docking station, instead of just placing it on top of one, but I don't need to carry any wires, I don't need to plug anything in, all the convenience is already there.

You could put low-power wifi antennas in each desk.

As required by the Ethernet specification, almost every Ethernet device actually already incorporates a transformer, which galvanically isolates the differential ethernet signals, providing common-mode rejection to deal with the problem of different ground potentials on different ethernet devices on different sides of a building.

I wonder if you could make a "docking pad" which incorporates a transformer with similar behaviour to the normal Ethernet isolation transformer and just substitute it in place of that transformer?
