Send your data through light

Matsushita recently showcased its Visible Light wireless technology that enables files to be downloaded onto a compatible device (a PDA in this instance) when you stand under it. This is a pretty neat idea, and it would work great in high tech museums where users can read additional data on the PDA right in front of the exhibit, giving the museum much more space to add in other interesting artifacts at the free space made available by removing pesky information boards. Another good point is this technology does not interfere with pulse-makers and other sensitive medical equipment unlike WiFi. Data transfer speed is comparable to that on optical fiber according to the Visible Light Communications consortium.
