Has anyone noticed that their Sprint Galaxy S3's occasionally seem to drop LTE after being steadily connected and not changing locations? My signal is -90dbm, and the connection seems relatively strong, but like clockwork, after 3 hours maximum, I switch back to 3G and am unable to get LTE back without toggling airplane mode.

Wow, I've never seen or heard that one yet. Can you get the phenomenon to repeat on different sites too? My GS3 has been rocky steady in LTE areas so far. The only time it will drop is in weak signal areas. I've never had it drop in strong or moderate signal areas like that.

It has also happened to me in Atlanta. Roughly the same use case though I can only infer that I had relatively good signal strength since I was regularly pulling down 6Mbps+, and it was the same type of behavior. After a few hours of use, it would just unceremoniously put me back on 3G and I would have to use Airplane mode (and once a reboot).

The next time it happens, check your LTE signal strength when you reconnect on your LTE Engineering screen. I'm curious ton see if your experiencing cell breathing.

I thought OFDMA techs didn't do this?

It's not supposed to. However, I have experienced some phenomenon where I believe that cell breathing may be occurring anyway. And it may be just a momentary thing and not like previous generations. But it may be just long enough to have your device lose connection. Given the rescan times on most Sprint LTE devices, it could get rather annoying if it's occurring.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      As far as I know it's ubiquitous. Ultimately the network decides if you should use VoNR vs VoLTE but pretty much anytime my phone is in standalone mode and I place a call, it goes over NR.   Yup, it was terrible. After a while, I just connected to the WiFi, and that worked fine at about 90Mbps. I get the feeling that rather than doing a "real" upgrade where they install new antennas, upgrade backhaul, etc., T-Mobile instead installed new radios onto the existing and already overloaded DAS and called it a day, which isn't enough. Compared to Yankee Stadium, where they actually went and deployed new antennas/radios for their n41 upgrade, and you're able to get upwards of 200Mbps at sold-out games, Arthur Ashe really is a joke. What's worse is that the folks in their NOC likely know this already, but no effort is being made to change that. I'm not asking for T-Mobile to deploy mmWave everywhere like Verizon but there is a real use case for it at stadiums.

      Does anyone know how well implemented is VoNR in the 5 boroughs. Does anyone use it? I have an iPhone 15 Pro. Does anyone know if T-Mobile is still working on upgrading their network? It seems like the service has gone down. My phone struggles in parts of the Belt Pkwy, and data is slow.

      I come to the US Open men’s semifinals and finals every year, and I’ve never been able to use my T-Mobile phone successfully. Usually AT&T is the top performer—good to hear Verizon has upped their game.

      One sector down, two more to go — — — — —  I was at Arthur Ashe Stadium for the U.S. Open today and the good news is that there is an n25/41 DAS setup throughout USTA Billie Jean King National Tennis Center. From the "boardwalk" to the outdoor concession area, to inside the stadium; you connect to standalone n41 and n25 everywhere via oDAS and iDAS. The bad news is that in the actual stadium it's beyond useless. While I saw strong coverage as indicated by signal bars and I was able to make calls and send texts, there was no data throughput at all. Running a speed test failed 9 out of 10 times. The only time I got a speed test to work was by switching to LTE funnily enough or by using NSA 5G where the test would initiate via LTE and then n41 would kick in giving me ~20Mbps. T-Mobile has so much traffic on their 5G network that now n41 gets bogged down before LTE. That was a first for me! In the stadium in the same area Verizon got 1.2Gbps on mmWave and LTE kept timing out when trying to test it. My Boost line on AT&T got upwards of 150Mbps on C-band and I know they have mmWave deployed as I saw their Nokia mmWave antennas deployed but I was unable to test it. In the outdoor concession area T-Mobile performed well getting over 150Mbps on n41. AT&T in these areas saw over 250Mbps on C-band and I didn't get the opportunity to test Verizon there. It just seems like 140MHz n41 is not enough capacity for the amount of people inside the stadium. Hopefully T-Mobile is considering deploying n258 to all of these stadiums since they now own that mmWave nationwide. It'd make a world of difference in terms of capacity at these venues.
