Gigafy your future

Centered around the 60 ghz frequency range is about 6000 MHz of completely unused, unlicensed spectrum. It is about to change your life.

This spectrum (100 times faster than the best wifi) is available because it is totally useless. If the radio signal bumps into an oxygen atom, energy is absorbed. Since most if the planet has oxygen and humans generally like oxygen, the signal can only be received a short distance and must have direct line of sight.

So it could eliminate cables within a room – say to connect your Internet router to your HDTV, your computer, your network attached storage.

It also uses one of the clever ways to allow people to share spectrum – using no moving parts, create a beam that points directly at the receiving device instead if a wide swath, cutting down on interference and reducing radiation unless you’re standing right in the line of sight.

    I gigafy mine every morning when my coffee gets cold before I finish it – I put it in the microwave and let these waves warm its water molecules.

    millimeter wave technologies have existed for decades, but I am not sure that they are using the exact frequency range you cited, Art.

    They have been used for high resolution radar, seeing through people’s dry clothes at airports to image their water-based bodies.

    If you think Gilligan’s Island is painful now, wait until someone beams you Dawn Wells with a little too much power – giga hurts! 😉

    There are even non lethal laser weapons that heat people with microwaves and cause intense pain.

    Ummm, Mary Anne,,

    What frequency is Bluetooth operate on ? Its line of sight or acts like it

      “What’s the frequency, Kenneth?” – remember when Dan Rather was asked that on the streets of New York?

      2.4 – 2.48 Ghz – it is low power and doesn’t go far, but it is not actually line of sight if you are nearby.

        A bit of trivia, Dan once appeared on stage at Madison Square Garden with R.E.M. performing their tune “What’s the Frequency, Kenneth?” written to commemorate that infamous incident:

          That is awesome! I had no idea that he did that with REM. Wonderful.

          He has a good show “Dan Rather Reports” on what used to be HD Net. I forget its new name, but it is the network out of Dallas with the Mavericks’ owner.

          I know most of the participants on this blog are conservative and Dan is liberal, but most of his shows are like his 60 minutes segments were rather than overtly political.
