Infra Red networking for the 21st century?
So, some crazy German boffins decided that the age of people lining up their computers to point at the IR port on things was a good thing and have developed the technology further, to the extent where they have now shown a demo where they gained 800Mbps via their method.
Applications being discussed seem to focus mostly on hospitals and similar, where interference from current wifi systems is a problem with some sensitive equipment, but it has got me thinking about the potential in schools.
Imagine it? In each room, you install the lights in the ceilings above the desks, laptops/tablets/etc... would be equiped with transceivers also. You'd be able to get amazing density, at high speeds with no interference (well, other than the occasional flailing arm, or looming head, but I'd imagine that like most light based systems, you would be able to design it to work with multiple paths, so if the direct above the device path was blocked, it would be connected to the next light at an angle instead), and it'd end the scare tactics the world is seeing about wifi in schools.
Hope they manage to turn it into a commercial system!
