As Milanovic’s screenshot shows, AT&T has a 5 MHz-by-5 MHz network running in the 1900 MHz PCS band — band 2 is PCS — which previously contained only HSPA and GSM signals. Commercial devices are already connecting to the network.

Seems like AT&T is just adding capacity rather than boosting speeds a ton. But doesn't having this many bands become confusing for them?

I wouldn't say it would make things confusing for them, considering they have always had PCS spectrum, but it was always used for 2G/3G. So adding that extra LTE band of PCS probably doesn't affect them very much.

AT&T also has some spare 700MHz spectrum they can throw at the problem. Bands A, D and E have not been touched yet. 850Mhz as well. The WCS band will not be needed for a long, long time.

Yes and no.  AT&T has no Lower 700 MHz A block spectrum.  Avoided it like the plague -- for technical and/or political reasons.  And the Lower 700 MHz D/E block spectrum is unpaired, so it is not really useful yet.

You're right about Block A. Verizon tried to sell it but had no takers in the urban areas so they decided to keep it. As far as D&E block can be used as a supplemental downlink for PCS.

No equipment supports that carrier aggregation.  So, as I stated, the spectrum is not really useful yet.

Could Sprint customers ever roam on AT&T's 1900 LTE if there were a roaming agreement in place? This isn't a "will it ever happen" type of question. I'm just wondering if its possible.

Yes it is technically possible. I saw my phone scanning C Spire LTE in the standard PCS block, it wouldn't authenticate. C Spire roams on Sprint's LTE.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
    • "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline June 1 for 850Mhz of mmWave in most of Ohio covering 27500-28350Mhz expiring 6/8/2028. No reported sightings.  Buildout notice issue sent by FCC in March 5, 2024 https://wireless2.fcc.gov/UlsApp/letterPdf/LetterPdfController?licId=4019733&letterVersionId=178&autoLetterId=13060705&letterCode=CR&radioServiceCode=UU&op=LetterPdf&licSide=Y&archive=null&letterTo=L  No specific permits seen in a quick check of Columbus. They also have an additional 200Mhz covering at 24350-25450 Mhz and 24950-25050Mhz with no buildout date expiring 12/11/2029.
    • T-Mobile Delivers Industry-Leading Customer, Service Revenue and Profitability Growth in Q1 2024, and Raises 2024 Guidance https://www.t-mobile.com/news/business/t-mobile-q1-2024-earnings — — — — — I find it funny that when they talk about their spectrum layers they're saying n71, n25, and n41. They're completely avoiding talking about mmWave.
