I found a rather interesting idea being implemented by city officers in St. Cloud. Apparently they’re installing ceiling lights that flicker faster than the human eye can see in order to transmit data. This supposedly will ease congestion on the wireless network but I really wonder why they don’t just install more access points if that’s their problem (seems the easier and cheaper solution). Still this type of data transmission should be interesting so long as everybody works with all the lights on (which often isn’t the case as many companies).
Personally I think it’s kind of a dumb idea just because it requires you to have your work environment setup in a specific way (namely lights on) in order to get Internet access. Wi-Fi is great because you just need to have an access point and a wireless card in your laptop without any specific changes to your work area.
