224GB/s, killer security, no radio interference—but you can’t block the beam.

    Imagine if they encased this light beam in some kind of fiber encasing so it retain it benefits but not worry about getting blocked. We could even call it a fiber optic cable or something

    I burst out laughing while reading this article, it’s laughably bad, written by someone who doesn’t have the slightest understanding of the content matter.

    Virtually all existing communication mediums are light based, since “Light” is a term that covers electromagnetic waves spanning a range from radio waves, all the way up to xrays, with visible light getting a small part of that range in the middle.

    With all light there is a tradeoff where higher frequency light can carry more information at the cost of lower penetration. It’s why your 5Ghz wifi is faster than your 2.4Ghz wifi but the 5Ghz doesn’t reach as far in your house

    Visible light is in the 400-800Thz (Terahertz), so it’s orders of magnitude better for transmitting a lot of data but since it’s blocked by most materials it works better if you use something to channel it, like a glass tube. Which is why visible light is already used extensively as the backbone of the internet, aka fiber optic cable. (to be completely accurate, most fiber optics use near visible infrared light, just below the visible spectrum, since it doesn’t scatter in glass as easily)

    The new communication standard referenced is nothing ground breaking, it’s just a standard for any niche application which can make use of it. It’s not a new technology, and if it was better than existing methods we would already be using it.

    I mean … that’s great for outer space. Not so much down here, except in pretty niche applications.

    I mean, you’re basically making a data lamp. Hold your phone up to it, get super fast wifi. That’s … niche at best, here on Earth. More refined VR eventually, I suppose?
