With this topic, we'll attempt to post 600MHz market activations by T-Mobile as soon as the information becomes available.
T-Mobile has announced a very aggressive schedule for 600MHz deployments (http://radioactiverf.com/news/t-mobile-announces-plans-to-launch-in-600-mhz-band-in-2017/), including in many markets before the end of 2017, which of course means testing prior to offering service to customers.
Most of the first markets T-Mobile will fire up will be rural and suburban, with major markets beginning early 2018. At this time, we have no news regarding any of the other carriers, but we hope to in the future.
As a reminder, the new 600MHz bandplan above channel 37 is:
-
Commencement of operations in Cheyenne WY and south of Portland ME beginning July 31, 2017

Commencement of operations in Cheyenne WY and south of Portland ME beginning July 31, 2017
Hi Henry,
Thanks for posting this. As someone who lives right near Portland, ME I'm going to have to take action in the short term, it appears. All that is left to work with is between 642 and 668... pretty cramped!
Best regards,

Henry,
Thanks a million for sharing this info. It's deeply appreciated!

This page is an over view of the entire sale and includes an animated plan for T-Mobile's rollout. Not exact but Henry's notices will be more real...

I think you need to be looking lower, below TV Ch 37. There was some discussion about using guard bands but I don't recall the legality of using vacant blocks in the 600mHz band.
-
Thanks Tim - I'll check. This is just a stopgap measure for me as things are coming at us quickly.
I know we have to vacate. 600MHz by end of 2018...

I think you need to be looking lower, below TV Ch 37. There was some discussion about using guard bands but I don't recall the legality of using vacant blocks in the 600mHz band.
It will not be legal (sans an STA) to use vacant blocks after the transition period concludes in July 2020, just as it's not legal to use fallow 700MHz channels.
Nor will it be legal to use the two 1MHz guard bands (616-617 MHz and 652-653 MHz).
The 600 MHz spectum above 614 that will be available to wireless mics are*:
614-616 Unlicensed wireless mic operations only.
653-657 Part 74 licensed operation only (part of the duplex gap).
657-663 Shared unlicensed mics and TVBD/WSD (part of the duplex gap).
*20mw ERP maximum.

Henry, do you have an FCC source for this information? The "layman's page" on the FCC website seems to indicate the guard bands and duplex gap will be available for wireless microphone use indefinitely.
https://www.fcc.gov/general/wireless-microphones-0
"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."

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.

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.

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

This is T-Mobile's website (https://howmobileworks.com) 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?

Incidentally, thanks to you and the other wireless pros for keeping us posted on your findings on this subject. Very helpful info!

Fixed.
Thank you.

First - I'd like to acknowledge the help and assistance of the 600MHz spectrum group at T-Mobile for their understanding and willingness to provide as much advance information on their 600MHz deployments as their legal department will permit. Their communications and assistance will hopefully minimize the pain for most.
Some important updates:
1) Due to the way they've conducted their initial testing in the first two markets (Cheyenne, WY and Portland, ME), when T-Mobile now commences service in additional markets the actual testing is only about a day's worth and then it's full service.
2) Major markets, including metro areas, will be seeing service beginning as early as second quarter 2018.
3) Although T-Mobile for the most part has two to three blocks in each major market and three to four in secondary markets, virtually all as adjacent pairs, the initial commencement of services in 2018 will only be a single downlink/uplink pair in major markets and two block pairs in the secondaries. These will be the the most centered block pair(s); C or C & D. The remaining blocks will come online mid to late 2019, after IEEE publishes the final 5G standards (5th generation of cellular phone system architecture, not 5GHz) and cell site radio OEMs provide updated software and firmware.
4) Although right now T-Mobile is only providing commencement of service information at a county level, we are working on getting a bit more granularity for the large counties (such as those out west).
Regarding the other new 600MHz licensees (Comcast, Dish and others), there is still no direct line of communication with any knowledeable representatives from any of these entities. Cellular industry chatter suggests it will be a while before any of these licensees light up, but do not become complacent: Whereas T-Mobile understands the advantages of an open line of communications, the others probably do not care and will simply commence service with little or no warning, other than 120 letters to LPTV and translator owners as required by FCC regulations (maybe).

Holy sh*t! So much for the 39 month transition period, in case anyone still had the fantasy that that was a thing. Thanks for doing this, Jason!
-
The 39 month was never a guarantee. Only a best case if the wind was to your back. I’m still suprised that there hasnt been more discussion of what impact the Microsoft Whitespace plan will have on witeless mics in the UHF TV band. In my opinion this will be the killer.

Wow, that's a great resource - thanks!
Based on a quick look, I'm very happy that I'm in Chicago rather than New York City.

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.
Can someone confirm I'm understanding this correctly?
As long as I stay between 653-663, my Sennheiser wireless system will be fine? (which is B-Band 626-662 I believe).

Yes, but no. The issue is more that the equipment you're using now will lose its FCC certification on July 13, 2020 because it will still be able to tune to frequencies within the auctioned spectrum, and operate at a power level greater than 20mW. So although you might operate only within the 653-663 MHz range if you have a Part 74 license, or 657-663 if you don't, and set your transmitter to 20mW or less, the equipment will not be in compliance with the new technical rules and thus you'll be operating illegally.

Thanks Henry. I guess my question should have also stated. Maybe my device itself is not complaint, but I can operate with a frequency range that is considered legal, so I should not have interference with (for example) T-Mobile?
That's certainly a situation that would be fine for me. If the FCC wants to swing by the bars I play at to investigate my wireless mic...then shame on me and I'll accept the consequences. But otherwise, it seems like I can squeeze for life out of my Sennheiser unit.

Operating within the prescribed band (653-657, 657-663 MHz) at or below the correct power level, virtually insures you will not cause interference to, or suffer interference from, the adjacent channel wireless carriers, which is mostly not T-Mobile. Except for about a half dozen markets where T-Mobile acquired 600MHz LTE blocks A or G, it will be other carriers adjacent to the duplex gap.
That's certainly a situation that would be fine for me . . . But otherwise, it seems like I can squeeze for life out of my Sennheiser unit.
It's likely not wise to state on a public forum your intent to flout federal regulations; low hanging fruit, steep fines and all that jazz. Neither action is condoned or recommended.

FYI I updated the map on 4/5. Guys, it's important to keep checking on these. I see that they pushed back their Nashville deployments from Q1 to Q3. I doubt that it's the only instance of changes.

at this point in time, 3/19, what are the legal operating criteria for the 600 band?
If TM has deployed is it illegal to operate? I was under the impression that when they took over a market it was then void.
This of course before the loss of certification in 2020
***** i got my answer. this reply can be deleted

FYI, a fellow from T-Mobile came by my booth and mentioned that recently they turned on 100 towers in They hope to keep that pace going too. It is a fast changing world out there.

On Friday April 12th I worked two different events in the Los Angeles area. On the corporate one during the day their wireless Telex com system was taking hits, even though it was working the day before. Yes, it was in the 600MHz range and the production knew that it would eventually be illegal.
Then that same night as I was working as a local A2 for a first national Broadway tour they experienced transmit/receive problems with at least 5 packs, all in the 500MHz range. Those packs had been working fine for the prior 17 days of their sitdown in Los Angeles.
The next morning I had to rescan my television because a few channels had moved.
I think I experienced the T-Mobile deployment in one day. The Broadway tour has their wireless racks hooked up via Wi-Fi to the vendor's server and receives updated scans of the area, but the deployment and channel move happened quicker than the vendor could update the channel frequency scans.
So when the map says that T-Mobile is deploying on a certain date, believe it.

I was rereading this thread and I was wondering if you can answer a question regarding this statement you made regarding steep fines?
I have been telling people that if caught violating this (is it a rule a regulation or a law) the chances are that they will first be issued a cease and desist order. If they don’t cease and desist using the device (or devices) that violates this that they will then be fined. And the fine is for each device and each incident. So if they have 10 wireless mics in use the fine could be $$$$$$ times 10 per usage. And this enforcement will come from the FCC based on complaints.
Is this correct and what is the dollar amount of the fine? I am curious if I have the numbers and information correct, because I can’t remember where I first heard it.
