[Huffpo] LVX system: ceiling tiles connect wirelessly to internet without wireless.

post #1 of 26
Thread Starter 
Pretty nifty idea, but what can the throughput on something like this be?
Probably sufficient for menial office tasks, though. Emails, word docs, .ppt, etc.

Quote:
ST. CLOUD, Minn. — Flickering ceiling lights are usually a nuisance, but in city offices in St. Cloud, they will actually be a pathway to the Internet.

The lights will transmit data to specially equipped computers on desks below by flickering faster than the eye can see. Ultimately, the technique could ease wireless congestion by opening up new expressways for short-range communications.

Hmm, neat.

This would work great for a digital signage system, or a POS system. As pointed out in the article, all devices are currently setup for WiFi or Bluetooth. This would require an add-on device, or wait until it is more mainstream. What if your hand blocked the sensor?

I wonder how it would standup against an AP with a 4x4 setup (600mbps). Also, how it would compete with the current realtime locationing,tracking and roaming systems from companies like Cisco and Aruba. I wonder how many clients one light array can handle?

Definitely will be interesting to see where this goes in the future.

I think it's more of a "proof of concept" for little to no cabling or the beginning of what may become a practical technology. At the moment this sound pretty ridiculous.

wouldnt flicking the lights on and off kill the electrodes in the bulbs? they would have to use induction or plasma bulbs which would be very expensive.
