I have been getting more and more LTE Roaming on Tmo Band 66 in the Allentown area. Is this new, or am I just noticing it in places I haven't been to before?

Sprint has been purchasing roaming access to T-mobile sites for in market roaming. Helps them increase capacity and coverage for sprint users without resorting to building new cell sites.

Took a day trip to Philadelphia some weeks ago, and my experience was exceptional. I was on n41 basically all the time, except when the device started to overheat and disconnect NR, as the day was hot.

Rode Amtrak from NYC to Philadelphia and back, and T-Mobile was great. I locked SA south, and NSA north. Southbound the device stayed and held SA n71 without going to no signal, except for the immediate area outside the tunnel from Penn Station. From Harrison PATH station south to 30th, SA n71 didn't disconnect at all. The northbound trip was great on NSA also, quite often connecting to n41, with occasional drops to n71.

30th St Station has n41 coverage, but the tower that covers the station either is backhaul capped and/or is heavily utilized, as B66+n41 was only 110 Mbps. Walked from SEPTA Jefferson Station to the Liberty Bell, and it has 100% n41 coverage, and the tower which covers the landmark got to 600 Mbps very easily.

Got on the Market-Frankford Line out to 69th Street Transportation Center, and once the train went from tunnel to elevated, n41 was there, all the way to 69th Street. Tried and failed to run a speed test at 69th St as the device was warm, thanks to the temperature of the day.

Spectrum holdings

Here is what I found in Center City and on the MFL trip for T-Mobile:
n41 is 100 MHz, with EARFCN 516030 (2530.15 ~ 2630.15 MHz)
n71 is 10 MHz, using D and E blocks

B66 is 20 MHz
B41 is 40 MHz, 2558 and 2538.2 MHz at 20 MHz each.
B2 is 15 and 10 MHz. 15 MHz is all of C block, and 10 MHz is 1870-1880 MHz of B block.
B12 is 5, and B71 is 10 MHz, B and C blocks.

HSPA is still active, 1877.3 to 1882.3 MHz.

Sprint:
B41 at 2680 MHz (20 MHz) and 2521.1 MHz (15 MHz), and B25 (G block only) and B26.

T-Mobile B41 is nearly overlaps fully with their n41 block, except for ~2 MHz. Speeds and SNR were great on n41 and B41 on the tower outside the Liberty Bell which I found it and tested on. I wonder if this is a form of DSS.

HSPA is a strange one, as T-Mobile is squeezing 15 MHz of spectrum (10 MHz and 5 MHz HSPA) within 12 MHz of spectrum. I would assume come January 2022 it will be 2 15 MHz B2 blocks in Philly, with HSPA in the middle of the lower 15 MHz block, until HSPA is shut down.

Data has been added to Cellmapper in Philadelphia for T-Mobile and Sprint. Album of screenshots/data is here: https://imgur.com/a/XVKgvWk

I took another trip to Philly, and added some more data to Cellmapper, same thing as last time, NYC to Philly and back via Amtrak. This time, I expanded my mapping a bit, as I mapped the Norristown SEPTA line from a little south of Temple University all the way to Norristown, end to end on both the Norristown High Speed line and Market Frankford Lines, and quite a bit of Center City. There is quite a bit of small cells within Center City, worse Benjamin Franklin Parkway is a hot mess of small cells everywhere, as I think I was able to see 10 or 11 at once from all carriers in some locations. Figuring out who is who is going to be a challenge.

I would guess the sea of red dots will stay that way for some time, but I did find quite a few converted sites within the Philly region, and on the NEC in New Jersey, matching the numbering scheme I found in NYC (8xxxxx). I also found 312-250 sites along the NEC in New Jersey and in Philly. I wondered if there is any gig+ sites within Center City, but I found none. All sites got 500-700 down pretty easily, and the 30th Street station n41 issue has been fixed.

Been awhile since I did a post about Philly since there really was much new to report. The convert sites I have visited are pretty much empty, as even though I am deprioritized, I still got to 750+ on speedtests with n41, with 2 approaching 790 Mbps very easily. Still no gig+ sites found.

If anyone here is looking to check out keep sites within the Philly area, I made a list a few days ago of the sites I have found and others which I'm monitoring:

Took a trip to Philly recently, and there seems to be some gig+ sites popping up across the area, but not within Center City yet. eNB 58201 in Willow Grove is gig+ and 56749, and possibly one near NRG stadium. Also, the DAS for the subway system got upgraded with n41 on it. The stations have n41 signal available, but the tunnels are still LTE only and can CA n41 from the nearby station if it reaches. Nice and easy 500+ down on the DAS with n41. B41 has been cut down to 20+15 within the city, but its 20+20 on the outskirts. n41 is 100+40 with n25 at 10 MHz.

There are plenty of keep sites all over to find, and there are still sites that are broadcasting 312-250 that haven't been converted yet.

      Roaming experience in Japan

      By iansltx · Posted

      So, in summary, here are the options I tested: T-Mobile intl roaming - LTE on SoftBank, routes back to the US (~220ms to 4.2.2.4) IIJ physical SIM - LTE on NTT, local routing Airalo - LTE on SoftBank and KDDI (seems to prefer SoftBank), routed through Singapore (SingTel) Ubigi - 5G on NTT, routed through Singapore (Transatel) US Mobile East Asia roaming - 5G on SoftBank, routed through Singapore (Club SIM) Saily - 5G on NTT, routed through Hong Kong (Truphone)...seems to be poorer routing my1010 - LTE on SoftBank and KDDI (seems to prefer KDDI), routed through Taiwan (Chunghwa Telecom) I wouldn't buy up on the T-Mobile international roaming, but it's a solid fallback. If you have the US Mobile roaming eSIM that's a great option. Otherwise Ubigi, Airalo, or my1010 are all solid options, so get whatever's cheapest. I wouldn't bother trying to find a physical SIM from IIJ...the Japanese IP is nice but there's enough WiFi that you can get a Japanese IP enough for whatever you need, and eSIM flexibility is great (IIJ as eSIM but seems a bit more involved to get it to work).

      Roaming experience in Japan

      So, the rural part of the journey still has cell service for nearly all the way, usually on B18/19/8 (depending on whether we're talking about KDDI/NTT/SoftBank). I think I saw a bit of B28 and even n28 early on in the trip, though that faded out after a bit. Once we got to where we were going though, KDDI had enough B41 to pull 150+ Mbps, while NTT and SoftBank had B1/B3 IIRC. Cell service was likewise generally fine from Kawaguchiko Station to Tokyo on the express bus to Shinjuku Station, though there were some cases where only low-band LTE was available and capacity seemed to struggle. I also figured out what I was seeing with SoftBank on 40 MHz vs. 100 MHz n77: the 40 MHz blocks are actually inside the n78 band class, but SoftBank advertises them as n77, probably to facilitate NR CA. My phone likely preferred the 40 MHz slices as they're *much* lower-frequency, ~3.4 GHz rather than ~3.9, though of course I did see the 100 MHz slice being used rather often. By contrast, when I got NR on NTT it was either n28 10x10 or, more often, 100 MHz n78. As usual, EMEA bands on my S24 don't CA, so any data speeds I saw were the result of either one LTE carrier or one LTE carrier plus one NR carrier...except for B41 LTE. KDDI seems to have more B41 bandwidth live at this point, so my1010 or Airalo works well for this, and honestly while SoftBank and NTT 5G (in descending order of availability) have 5G that's readily available it may be diminishing returns, particularly given that I still don't know how to, as someone not from Hong Kong, get an eSIM that runs on SoftBank 5G that isn't the USM "comes for free with the unlimited premium package" roaming eSIM (NTT is easy enough thanks to Ubigi). In other news, I was able to borrow someone's Rakuten eSIM and...got LTE with it. 40 Mbps down, 20 Mbps up, 40ms latency to Tokyo while in Tokyo...which isn't any worse than the Japan-based physical SIMs I had used earlier. But not getting n77 or n257 was disappointing, though I had to test the eSIM from one spot rather than bouncing around the city to find somewhere with better reception. It's currently impossible to get a SIM as a foreigner that runs on Rakuten, so that was the best I could do. Also, I know my phone doesn't have all the LTE and 5G bands needed to take full advantage of Japanese networks. My S24 is missing: B21 (1500 MHz) - NTT B11 (1500 MHz) - KDDI, SoftBank B42 (3500 MHz) - NTT, KDDI, SoftBank n79 (4900 MHz) - NTT Of the above, B42/n79 are available on the latest iPhones, though you lose n257, and I'm guessing you're not going to find B11/B21 on a phone sold outside Japan.

      Official Tmobile-Sprint merger discussion thread

      T-Mobile acquiring SoniqWave's 2.5 GHz spectrum  Another spectrum speculator down! T-Mobile is acquiring all of their licenses and their leases. Details are lacking but it looks like T-Mobile might be giving them 3.45GHz in exchange in some of the markets where they're acquiring BRS/EBS to sweeten the deal and stay below the spectrum screen. Hopefully NextWave is at the negotiating table with T-Mobile so NYC can finally get access to the full BRS/EBS band as well.

      Network Vision/LTE - New York City Market

      Maybe. The taller buildings on one side of the street all have Fios access and the NYCHA buildings are surrounded by Verizon macros that have mmWave. I don’t think this site will add much coverage. It’d be better off inside the complex itself.
