New Lighting Technology To Wipe Out Wi-Fi Access?

Posted by Hemos on from the extinction-level dept.

Richard Evans writes "Focus on Broadband Wireless Internet Access has an article [cached by google ] on the potentially catastrophic interference to Communications Users Of The 2.4 GHz Band e.g. Wi-Fi, DECT and Bluetooth by a new lighting technology called RF Lighting."

  1. Is this a real light technology? by hackman · · Score: 4, Interesting

    The article makes a big point out of the collision between the frequency spectrums, however I personally am interested to find out more about the lighting technology that is "high efficiency and RF based". It seems the article kind of missed that explanation, and I can't find much information on it. The lighting's website is down that is referred to, and as far as I know this could be a "made up" problem (by this dude who wrote the article) primarily because it's only a problem if the lighting technology catches on.

    Are the light technology elements mounted in the ceilings like conventional flourescent lights or does it use some kind of a central light-source idea. If it's high-brightness and high-efficiency anyway, the light source could be placed at a central (shielded) location and fiber optics used to distribute the light.

    I'm all for new light technologies, although often flourescent lights are pretty good, there is still a lot of room for improvement. (Time delay to full brightness, hazardous materials, cheap ballasts that buzz, bad fluorescent tubes that put off funny-colored lights) But interfering with wireless spectrums (even unlicensed ones) seems like a bad idea in general... the amount of noise in any spectrum is becoming a serious concern for the design of "robust" wireless technologies.

    Why get all in a lather about RF lighting?

    If solid state lighting takes off we'll get great efficiency and no 2.4 GHz spectrum pollution.

    This article is utter garbage!!!

    The first link (off-site) from the article referred to, in fact the makor of said "RF-Lightning-Craptacular VC-Money Whoring" company has a "our website is under construction" on it.


    C'mon people - stop posting obvious flamebait articles at the highest level. This was a freakin waste of everyone's time.
