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.
