T-Mobile LTE & Network Discussion

It depends on where I am. What's glaring the drop from LTE to nothing. I was walking through Grand Central and my phone was sitting pretty on Emergency Calls only while my Sprint phone had 3G. 

 

It all comes down to site placement, and power output.

 

That's exactly what I was saying when I got to try T-Mobile for a day. There were 0 problems outdoors but once I got inside it took a turn for the worst pretty quickly. You'd drop from LTE to nothing so quickly whereas on Sprint, I'd at least have a decent EVDO signal. Coupled with so many of the 3G sites in NYC having fiber backhaul already, speeds would constantly be 1-1.2 Mbps.

Surprised you didn't get Hspa at least

I did but it isn't a very strong signal at all. One example I can recall is when I was at my mother's workplace and as I walked into the building, Sprint managed to keep a 1 bar LTE signal whereas the T-Mobile device dropped LTE quickly and when it switched to HSPA+ it was 1 bar and then it switched to EDGE which had a stronger signal but not by much. Meanwhile Sprint managed to keep LTE. When I went back outside, both device had a full signal on LTE.

^^^ is why TMO's business foray is doomed.

When I tried T-Mobile a few weeks ago, I would usually go from LTE to GSM or no service. I rarely ever saw hspa. LTE was pretty fast, but if I lost it data was unusable.

Delicious words

 

Interestingly, Son also addressed T-Mobile's recent "uncarrier" efforts in the market, and the carrier's recent resurgence in terms of new subscribers. He said T-Mobile's success is a short term phenomenon and that "we need a real fight, not a pseudo fight."

This is a year old.  I am sure it has already been posted.

It's quaint that even he thought tmobile's uncarrier is a short term phenomena.

 

Define "short term."  Orange is the new black.  Something will be the new magenta.  T-Mobile's 15 minutes will not last forever.

Now I'm not a fanboy or anything. I am here for knowledge and understanding what is going on in my Sprint market. 

 

You however are a fanboy and clearly only want to point out tmobile.  I don't get it. Trolling a website full of people like myself.  I disagreed with allowing a tmobile discussion thread for items such as this.

Well... on twitter Neal was sayin that fcc should fix up the 2.5ghz by splitting into 100mhz fdd and rest tdd.

100fdd is plenty for att, vzw, tmo

Personally, I've had a similarly good experience in Norwalk, Stamford, and Rochester. Even traveling between Norwalk and Rochester was quite smooth, as I had native access throughout nearly all of my trip up to Rochester and back down to Norwalk last week.

 

I wonder if they have the backhaul scaled up significantly, or something else is going on. I rarely see low speedtests, and that's using multiple servers, and not T-Mobile's own private "Speedtest.net" server.

It won't say band 12 but a easy way of knowing is if it does say band 4. If you need to know just open the engineering screen on the nexus 6 while connected or download LTE Discovery.

Does Signal Check Pro report T-Mobile's LTE B12? I'm wondering if it'll show once I get the band enabled on my Nexus 6 after the 5.1 update.

TMO doesn't have one anymore in Detroit.

Wonder why they dropped it.

Funny thing is, 2.5 ghz is labeled TDD worldwide, so that is going to work.

Actually, 2.5GHz is generally allocated for FDD technologies, with the major exception of the China and Japan. Technically, the U.S. allows both, but the licensing configuration makes it tough to roll out FDD unless you want to mix BRS and EBS.

 

In most countries, they follow the preferred ITU Option (option 1), which is set up as follows:

  • 2495-2500 MHz is a guard band for ISM, MSS, and BAS
  • 2500-2570 / 2620-2690 MHz is paired for FDD operation (3GPP band 7)
  • 2570-2620 MHz is allocated for TDD operation (3GPP band 38, but band 41 service can run here too)
  • Internal guards at 2570-2575 MHz and 2615-2620 MHz are recommended to prevent interference

This configuration is known as the "IMT Extension" configuration, as it was originally designated for high capacity 3G networks (which is why you can deploy UMTS WCDMA on it). But it is now known as the "IMT Advanced" band, where high capacity 4G networks are to be deployed.

 

Most countries following Option 1 do not bother with allocating the TDD frequencies. In CEPT countries, TDD frequencies are allocated because CEPT recommends it. CITEL (for the Americas) and APT (for Asia and Oceania) do not make the same recommendation, though they do recommend Option 1 configuration.

 

The U.S., China, and Japan technically follow Option 3, which permits mixed FDD and TDD throughout the band, and only mandates a 1MHz guard between ISM/MSS/TLPS/BAS and the 2.6GHz band, so instead of starting at 2495MHz, it starts at 2496MHz (which is why there have been issues launching LTE service on the BRS 1 block). However, China and Japan have set up their allocations and regulatory environment so that significant Band 7 allocations are still possible (though they haven't been done yet). The U.S.' confusingly split regulatory environment makes it difficult (though not impossible) to launch FDD service there.

 

Now, that being said, while 2.6GHz is recommended worldwide under Option 1, 2.3GHz (2300-2400 MHz) is recommended as an all-TDD band. CITEL, CEPT, and APT all recommend 2.3GHz for TDD service, which is designated as Band 40 for LTE. This is live all over Asia and Africa. Latin America and Europe are starting Band 40 deployments now. The U.S. is the only country where it is FDD only, and only a small subset of the band has been allocated for mobile services. That mainly has to do with Sirius XM doing things it shouldn't be doing with its SDARS frequencies (which sit in part of that band) and being permitted to do so. Consequently, WCS is currently set up as an FDD band, but with some work, it could be converted into a TDD band.

Will any reconfig + re-auction happen here?

TMO wouldn't be building out to 300mil LTE if they weren't veeeerry confident of their future.

Confidence != actual results, as the Nextel purchase shows, but you don't see Sprint building to 300mil; that difference aught to mean something.
