[TJ (Tom) Cornish]

My "source" is multiple FCC NPRMs, the FCC post auction data and T-Mobile for the various bits of information I'm able to disseminate and provide in a more coherent manner. I'm not quite sure what you're asking; the FCC statement you quote matches what I posted earlier. (Just note though that wireless mics will not permitted in the two 1MHz guard bands at 616-617 and 652-653.)

The quote I copied says "Spectrum will continue to be available...". I am not a lawyer, but I take that to mean those spectrum sections will continue to be available indefinitely as an end date was not mentioned.

I'm not doubting you, but as this seems to be the FCC's user-facing page for microphone users, I'm trying to understand if this is a page oversight, or if there is another FCC document that covers this that is parseable by normal people that I can forward to my clients that speaks more clearly to what you are saying.

The FCC statement is correct: "Spectrum will continue to be available for wireless microphone use on the other TV channels 2-36 (TV band frequencies that fall below 608 MHz), on portions of the 600 MHz guard band (the 614-616 MHz frequencies) and the 600 MHz duplex gap (the 653-663 MHz frequencies), and in various other spectrum bands outside of the TV bands."  These are the >614MHz frequency ranges that will be available after July 2020 when the transition period ends.

T-Mobile testing beginning Nov 1, 2017:

August 16, 2017

Re: Notification of T-Mobile Deployment in the 600MHz Band

T-Mobile USA Inc. is planning to deploy commercial wireless services in some or all of our
owned Spectrum blocks in the attached list of counties. This is expected to begin in November
of 2017. We plan to add to this list continuously. For each county on the attached list, we ask
that all use of spectrum in the indicated channel blocks ceases prior to November 1, 2017.
For your information, the following chart illustrates how the new wireless Band 71 overlays on
the existing UHF channels 38-51. We wish to minimize interference with the wireless base
stations and handsets that will operate in the new band and we want to avoid disruptions to any
operations currently in use.

[Pete Erskine]

Here is the cover letter which came with the county list of startup for 2017

[Pete Erskine]

T-Mobile will be energizing various counties throughout the continental US (all of the areas in the last T-Mobile email) before the end of this year.  Once they begin testing, wireless operators must cease operation of any device in the affected spectrum. Radio Active Designs is in communications with T-Mobile Spectrum engineers and will be posting test sites on our web site along with the specific counties throughout the US. 

Following is a map that our friends at Professional Wireless Systems have put together that provides details on the counties across the United States that T-Mobile plans on lighting up November 1.

[Cameron Stuckey]

In September I went to Portland, ME to see the second ever announced 600MHz T-Mobile tower for myself and to take some scans. I've attached a screen shot showing their operation.

T-Mobile won Blocks BCDE, but as you can see from the frequency markers in the picture they are only transmitting C and D. I can only speculate that that is to decrease interference to the lower and upper adjacent DTV channels until they complete their transition.

To note, these carriers are clean. There was some speculation early on that Guardbands and Duplex Gaps may have been too noisy to operate wireless mics. I am optimistic that the Guard Band and Duplex Gaps will be useable as the skirts of these carriers are small. Front end saturation may very well still be a problem depending on your location, but OOBE should not cause interference. These are different signals than we are used to with DTV. They are 5MHz per block rather than 6MHz, there is no pilot tone and they will be operated in many more locations than DTV towers, to be certain. Lots to reconsider as these systems begin transmitting, I hope this helps some of you.

They are 5MHz per block rather than 6MHz, there is no pilot tone and they will be operated in many more locations than DTV towers, to be certain. Lots to reconsider as these systems begin transmitting, I hope this helps some of you.

This is a great picture of what the towers are going to look like...assuming the folks looking after them are good citizens and don't try and cheat up the power to the point where we start to see spill into the guard bands.
But, this raises the question: What will the signal from the devices look like? That is something that we will be more likely to encounter, at close range inside a venue.

It's quite concerning that there seem to be at least 4 TV broadcasts still operational there, including in the duplex gap which is supposed to be for mics and whitespace devices only as I understand it.

I'm passing through Natrona County, Wyoming tomorrow. I'll try to get some detailed scans.

In September I went to Portland, ME to see the second ever announced 600MHz T-Mobile tower for myself and to take some scans. I've attached a screen shot showing their operation.

T-Mobile won Blocks BCDE, but as you can see from the frequency markers in the picture they are only transmitting C and D. I can only speculate that that is to decrease interference to the lower and upper adjacent DTV channels until they complete their transition.

To note, these carriers are clean. There was some speculation early on that Guardbands and Duplex Gaps may have been too noisy to operate wireless mics. I am optimistic that the Guard Band and Duplex Gaps will be useable as the skirts of these carriers are small. Front end saturation may very well still be a problem depending on your location, but OOBE should not cause interference. These are different signals than we are used to with DTV. They are 5MHz per block rather than 6MHz, there is no pilot tone and they will be operated in many more locations than DTV towers, to be certain. Lots to reconsider as these systems begin transmitting, I hope this helps some of you.

This is T-Mobile's website where they will be updating information on their deployments through the transition period [as their legal department permits]. At this time, they only list deployments at the county level. We are working with them to see if a bit more granularity can be provided for those particularly large counties.

And just a reminder: We are in the midst of the transition period (through July 2020). Things are transitioning for the next 29 months . . .

I think you may have missed a bracket and a keystroke in your link...  was this the one you were pointing to?
