FCC OKs Sweeping Spectrum Frontiers Rules To Open Up Nearly 11 GHz Of Spectrum (fiercewireless.com)
Monica Alleven, reporting for FierceWirelessTech: In one fell swoop, the FCC today put the U.S. in a 5G leadership position, voting 5-0 to approve its Spectrum Frontiers proceeding and make spectrum bands above 24 GHz available for 5G. FCC Chairman Tom Wheeler, noting his previous remarks on the proceeding, kept his remarks brief to avoid repeating himself. But he summed it up this way before the final vote: "This is a big day for our nation. This is a big day for this agency," he said. "I do believe this is one of the, if not the most, important decision this agency will make this year. By becoming the first nation to identify high-band spectrum, the United States is ushering in the 5G era of high capacity, high-speed, low-latency wireless networks. By not getting involved in the technologies that will use the spectrum, we're turning loose the incredible innovators of this country," he said. The new rules open up nearly 11 GHz of high-frequency spectrum for mobile and fixed wireless broadband -- 3.85 GHz of licensed spectrum and 7 GHz of unlicensed spectrum. The rules create a new Upper Microwave Flexible Use service in the 28 GHz (27.5-28.35 GHz), 37 GHz (37-38.6 GHz) and 39 GHz (38.6-40 GHz) bands, and a new unlicensed band at 64-71 GHz. The FCC will continue to seek comment on bands above 95 GHz.
You must be new here...
Sounds good for outdoor use, but above 10Ghz the signal starts behaving more like infrared than microwave and is going to struggle to get through walls I think.

Should actually be pretty safe unless the power level is really high because its hardly going to penetrate the skin.
Repeal the 17th Amendment TODAY! Also Please Read http://www.gnu.org/philosophy/right-to-read.html
Seriously you will still get ripped off royally by the cellphone carriers, who will charge you over $100, for a network speed you'll never get with less than 5GB of bandwidth per month. So this means nothing.
Errr... how does a lightbulb generate light at 750000GHz from 60Hz AC?
The FCC needs to take back control of all spectrum and assign one company (fully regulated) to implement the towers/technology then let the providers lease space on the towers for their customers. They now compete on service and can't play games with throttling streaming competitors.

Although Summary makes it sound like this is entirely a 5G thing, the unlicensed 64-71 GHz band suffers from high attenuation due to rain and oxygen, and aren't useful for distances more than about 1 mile. So this spectrum is clearly aimed at higher speed wifi (multi-gigabit).
You must work in IT.
Does this mean there will finally be decent wireless broadband in rural areas?
If it was LOWER than 2.4GHz then yes.
If instead of selling off *ALL* analog TV channels to the highest bidder
they would have kept ONE channel and made that unlicensed,
NOW THAT WOULD HAVE BEEN EXCITING!
Instead we get frequencies that are block-able by clouds.

I'd be inclined to agree with you - for thinly populated areas.
You do realize that (for a wide frequency band) the EM spectrum is a shared resource? Like the air we breathe: if I start a fire, that removes oxygen from the air around it. And puts smoke in the air. Smoke that will be visible from a distance, and the combustion products may affect people in a wide area. Therefore (in most populated areas) people are not free to burn stuff out in the open as they please. Such activities may be regulated, and rightfully so.
Above certain EM frequencies (say, IR and up), the physical properties of signals make it pointless to try and regulate things. Below certain frequencies, lack of practical applications make regulation not-needed / pointless. But in between, we're talking about a shared (and limited!) resource. So some government regulation is quite appropriate.
Frequency multipliers and other fancy tricks.
You generate a 10mhz signal, then add it to a 20ghz sine wave. Bingo you've got a 10mhz channel at 20ghz.
That's a simplification of what wifi channels do.
Use a 60GHz diode and amplitude modulate it as one example.
I'm sure all US citizens will soon have to comply with the new Network Distribution Privacy Act (due to be announced soon) which means allowing at least one, or when required for coverage, two 71GHz transceivers in every room of their private property. When multiple operators are active in your region that will of course double or more. Service personnell must have unrestricted access to ensure full network coverage at all times.
People, stop the madness. Go out, leave your phone at home, get a life.
To Terminate, or not to Terminate, that's the question - SCSIROB
At those wavelengths, aren't the transmitters going to need to output a rediculous amount of power in order to get any reasonable distance, and for that matter, don't the transmitters themsevles get even more inefficient? This on top of the obvious attenuation problem from just about anything, including raindrops?
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
I'm OK if they are forced to use it for >= 5G... if they won't provide 5G willingly, and are holding it hostage to a crippled net neutrality: sorry: I guess you don't get new spectrum.

And yes, I'm aware, that most of the asses in the /. article are European, but some of them are the same companies in both the U.S. and Europe.
My first guess for why people are not free to burn stuff is because things that are not theirs are more likely to catch fire, and a lot of other stuff.
I'm not sure how much your reasoning holds water as air is mobile and if that was really the issue there would have been more problems back in the time where fire was the main method of keeping warm and cooking. We talk of the great fire of London and Rome burned while Nero fiddled because of stuff burning not asphyxiation. Of course, in enclosed and insulated spaces there are issues and that's a more modern thing. Though the chemical composition of things that get burned these days have changed too, to having a more toxic composition. Still, my original analysis is more time-worthy.
First you have to get it really excited
Or maybe you could try using an array of directional antennas. I'm still learning all the conventional wisdom, and the workarounds that make them not all hold water, but I use three indoor antennas attached to one television to pick up channels, and what I read on the ARRL website would seem to suggest that the signals should either cancel themselves out as when impromptu karaoke tracks are made, or be out of timing alignment with each other which are kind of variations on the same problem. There are any number of ways of tackling the problem and I'm not even sure the problem has been identified correctly as among other things when it gets explained, the effects of relativity don't seem to be taken into account, and don't anyone go expecting me to put into words for them my limited understanding of relativity, though if anyone else feels so inclined to express their understanding, well go ahead.
You generate a 10mhz signal, then add it to a 20ghz sine wave.
Actually you MULTIPLY it, which exercises a trigonometric identity that creates two new "sidebands":
- The 10 mHz signal with the frequency of each component of it shifted up by 20gHz (i.e. a component at 10 mHz would appear at 20gHz + 10 mHz, a component at 5mHz would appear at 20gHz + 5mHz, etc.)
- The 10 mHz signal with the frequency of each component of it interpreted as a NEGATIVE frequency (i.e. frequency-inverted) and shifted up by 20gHz (i.e. a component at 10 mHz would appear at 20gHz - 10 mHz, a component at 5mHz would appear at 20gHz - 5mHz, etc.)

You do realize that (for a wide frequency band) the EM spectrum is a shared resource?
You do realize that (for a wide frequency band) the audio spectrum is a shared resource?
Why don't we have a Federal Speech Commission regulating the use of the audio spectrum? Just think: If everyone talks at once, nobody can hear each other. If some people talk louder they drown others out. If people talk at night they keep others awake. And so on.
By the same arguments used to claim regulation of the radio spectrum is necessary to smooth functioning of radio communications, it is also necessary for the smooth functioning of speech.
So we need to be licensed before we can talk. Some of us would be licensed only talk in low growly voices and others in high squeeky voices, to better avoid interference. All of us would be limited to speak below an assigned loudness level an only in certain places. Certain words would be prohibited, as would advocacy of the consumption of certain products (such as cigarettes). Some subject (such as "adult" activities) could only be talked about during restricted hours. Special licenses would be needed for high-power amplifiers, such as megaphones. I could go on.
That pesky First Amendment puts a big roadblock in the way of common-sense regulation of speech, without which SO much less audio communication can take place.
