    I predict a Resonance Cascade with those high frequencies!

    "I never thought I'd see a resonance cascade failure, let alone cause one!"

    Now we just need storage with the ability to read/write at similar speeds.

    Close, but not close enough methinks.

    That's not a problem: pretty much any mid- to top-end consumer SSD can handle 500MB/s read and write, which is 4Gb/s.

    One major problem I foresee: bad science.

    If wireless is bad for us (my acupuncturist homoeopath told me it was, so it must be true) and that works in the GHz range - so surely something that works in the THz range must be a thousand times worse for us? ;)

    How long before the luddites suggest something like that?

    On a more serious note, any wireless system that is capable of working through my 2 foot thick walls would be very welcome by me. It's a shame that we're probably at least 5 years away before a viable commercial version is available...:(

    The problem with getting workable solutions at this frequency is that it gets much harder to have a reasonable output power, which means short range. One of the other main problems is tuning which involves tailor made parts and lots of testing/retuning to get right (although that's going on my experience of top end R&D equipment so it may be that they've cracked it for lower/consumer parts).

    At 1THz and up, your DNA starts to cracking down. No, I'm not kidding at all!

    that's really high freq.. I'd like to see the antennae that delivers- sounds like a gimmick if it has no range

    oh well threw some numbers into a modeler.. you could theoretically get 4x the distance using a small 3 element yagi =] but the f/b ratio is horrible not to mention the pattern, needs a lot of tweaking.. least the numbers put it in the ballpark though

    why not just run a cable :D
