Whether you’re using wireless internet in a coffee shop,
stealing it from the guy next door, or competing for bandwidth
at a conference, you have probably gotten frustrated at the
slow speeds you face when more than one device is tapped
into the network. As more and more people and their many
devices access wireless internet, clogged airwaves are going to
make it. One germen phycist.Harald Haas has come up with a
solution he calls “data through illumination” –taking the fibber
out of fiber optic by sending data through an LED light bulb
that varies in intensity faster than the human eye can follow.
It’s the same idea band behind infrared remote controls but far
more powerful. Haas says his invention, which he calls DLIGHT,
can produce data rates faster than 10 megabits per
second, which is speedier than your average broadband
connection. He envisions a future where data for laptops,
smart phones, and tablets is transmitted through the light in a
room. And security would b
