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

Fixed.

Thank you.

T-Mobile Deployment Update.
« Reply #21 on: December 16, 2017, 11:28:25 am »

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).

Thank you, Henry!  Here's that data, sorted and mapped.  https://www.google.com/maps/d/viewer?hl=en&hl=en&mid=1b_LOMSl3Xewr7VEzK6OkqrlJKJQBwqgU&ll=39.71440121216505%2C-96.2548908&z=4
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. Iím 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).
