FCC 600MHz Auction Update
« on: April 29, 2016, 02:49:05 pm »

The FCC issued a public notice today announcing:

- 126 MHz initial spectrum clearing target (set by the Auction System’s initial clearing target determination procedure. In other words, over the last 4 weeks enough broadcasters formally committed to participate in the reverse auction that FCC figures there’s 126 MHz of spectrum to be sold).
- Band plan for the initial stage of the incentive auction (basically down through channel 30 / 566MHz).
- Actual reverse auction begins May 31st.

The Public Notice is here.

Here's the best guess at the timeline going forward from today:
- Reverse auction will take about 6 to 8 weeks (July 31).
- Results of reverse auction and issuance of Public Notice will take about 3-4 weeks (Aug 31).
- Forward auction will begin maybe a couple of weeks later, and take anywhere from 4-10 weeks (Nov 30).
- Several weeks (months?) for results of forward auction and issuance of Public Notice including new band plan (sometime 1st qtr 2017).
- 39 month transition clock starts for deadline to vacate (2nd qtr 2020) . . . BUT if testing begins sooner in a given market, low power devices must vacate sooner. Testing of new systems in major urban markets will begin as early as 3-4 months after Public Notice is issued (figure beginning of 3rd qtr 2017).

So 600MHz UHF mics/coms/IEMs/IFBs will likely begin to experience interference in major urban markets as early as early as summer 2017.

This can't be good...

Today the FCC announced that it has "cleared" 126Mhz of spectrum in the first phase of the 600Mhz auction. While I don't fully understand all the ins and outs of this process, I think this means they have agreements from broadcasters to vacate their current spectrum so the FCC can auction it off to wireless carriers. The 126Mhz is the maximum amount the FCC was shooting for, which will probably mean the maximum detrimental impact on our industry after that spectrum is then successfully auctioned off to the telco and data industries. Someone correct me if I am reading this wrong.

Somehow I missed that the 600mHz auction would go below 598-ish.

All this so people can stream content to a tiny box.  Bah, humbug.

I'd like it more if I made money from it.  And what is "facebook"?

I dunno... It's what the kids are smoking these days, I think.

That's been my exact point all along. Zuckerberg gives me a couple thousand bucks I'll start a stupid profile.

Oddly enough I'm not so sure this is total doom for our industry.

We haven't seen how much companies are willing to pay for this spectrum yet. We've only seen that broadcasters are maybe more willing to vacate than we might have guessed.

Yay, now my whole 8-channel IEM rig is trash too.

I would like to be optimistic, but I can't find a reason why wireless phone companies wouldn't pay whatever it takes to gobble up all the spectrum they can. I feel like if they were offered the whole UHF TV band they would buy it. I mean this is the primary way they make money, and they want as much spectrum as possible because that means more tx/rx frequencies, which means fewer devices on each frequency, which translates to higher throughput and faster speeds right per device, right?

But lets hope they don't hit that target.

On a related note, is it possible for them to exceed that target still, up to the worst case scenario in that chart (everything gone above TV 26) or even beyond that?

It hasn't worked this way for a long time.  There is no concept of channels in spread spectrum.  It's all about occupied bandwidth.  The spreading algorithm distributes the energy across the available spectrum.  Each communication is started with the exchange of a seed number that begins the pseudo-random sequence.  The remote device looks for a bit of data at that moment in time space.  That is how the bitstream is recovered.  Cell splitting is for capacity (less energy per cell = more subscribers) not for RF management in the classic sense.

Devices still think in terms of bands because of antenna, filters etc.

Mr. Google found this for me, a great introduction to spread spectrum.  I learned something, it was designed by a musician.  Which makes perfect sense as music is the ultimate spreading algorithm and the aesthetic being the prime driver.

And wonderful Hedy Lamarr, hands on the piano keys... the whole story is a thing of beauty.

Great article by the way. Still not quite grasping how you can recover an RF message below the noise floor ???

Without the right key, the spread-spectrum signal appears as noise or as an interferer. (Scanning methods can break the code, however, if the key is short.) Even better, signal levels can be below the noise floor, because the spreading operation reduces the spectral density. See Figure 6. (Total energy is the same, but it is widely spread in frequency.) The message is thus made invisible, an effect that is particularly strong with the direct-sequence spread-spectrum (DSSS) technique. (DSSS is discussed in greater detail below.) Other receivers cannot "see" the transmission; they only register a slight increase in the overall noise level!

Still, and again, a thing of beauty.

Yeah, I don't really get this either, but GPS does it all the time.  I'm suspecting black magic is involved.

Gray magic.

It's May 31st and that means along with recuperating from the weekend's festivities/jobs, the FCC Reverse Auction started at 10:00am EST this morning. As of the conclusion of Round 1 at 4:00pm EST, no broadcasters who are participating in the auction have offered to sell out a price less than the market capitalization amount assigned their license. And why would they, at least this early in the game. My prediction is eBay-style sniping (though in reverse) during the last round or two.

Is there something at this link that I'm not seeing? It appears to me just to have the schedule of the various rounds but no other information.

Thanks

This came in today from the Shure rep:


"FCC Chairman Tom Wheeler acknowledged the government agency may need to conduct further reverse auction stages should forward auction bidding not meet the current $86 billion clearing target. Those additional stages could result in less spectrum being transitioned from television broadcasters to mobile telecom operators.”

Saw that - this is good news at the very least in terms of time frame, and perhaps even in terms of how much spectrum is re-claimed.
