Bands are identified by GCI patterns. Sprint has a very defined pattern, which makes it easy to ID bands. Unfortunately, T-Mobile does not seem to use any pattern at all for 700MHz, so Signal Check is going to be inaccurate more times than not. The only way to reliably identify T-Mobile bands is by using the engineering screen, if available.

Yea that makes sense. I was wondering what pattern or method Mike was using to have Signal Check identify one verses the other.

Just noticed yesterday that SignalCheck Pro said I was connected to an LTE 700 B12 site for T-Mobile, but I was actually connected to a B4 site.  There seems to be some sort of error in how it detects B12 for T-Mo.

<p>

 

Right now its included in the beta build (4.272b and above), see the change log here for additional upcoming goodies.

• Added indicators for T-Mobile LTE band 12.

Awesome, thanks! Looking forward to the update!

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.

Cool thanks.  Just got the update so I'll try it out.

Not sure if this has been asked.... will 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.

Cool man!  I'll have to check him out.

haha nice a 116 fan?

Yes sir!  You??

In my area it didn't happen until AT&T started deploying LTE.  When we are on WCDMA, we have no issues.

Weird... you'd think there'd be more noise about this issue.

No, it's single path transmission.  It requires a network with a well functioning CSFB network.  SVLTE Android devices are unaffected.  The Z10 may be designed to work like the iPhone.  So it may be true to say that the OEM's that are using Android have decided to use a technology that utilizes CSFB on provider networks.  However, it is not an issue with Android software in and of itself.  An Android OEM could build a device that runs single path LTE like an iPhone or BB.

 

Robert

That I get, but what I'm wondering is why these problems have started happening suddenly.  I understand the concept of the CSFB network but I don't get why it was working for some time then stopped.  The reason I brought up Android is because of the timing of getting the 4.3+ updates on several phones and this problem surfacing.

My wife has had the same issue with AT&T too with the Nexus 5. I haven't. But I am not in LTE coverage very often either. Except with AT&T, it doesn't appear that texts are going through LTE like they do on Sprint. So when she gets back on WCDMA, she will get all her texts at once.

 

And if you call AT&T customer service, they will just cut you off and tell you it has to be the device and they do not support the Nexus 5. Then they they to sell you a phone they do support. I hate AT&T. At least Sprint (and Tmo) are doing something about it.

I'm wondering if it's an Android issue.  It doesn't seem to be phone specific but more network it seems.  My friend also on T-Mo but with a BB Z10 isn't having the issue.  On T-Mo, I'm pretty sure the texts are going thru LTE.  But whenever this issue started happening, I started getting texts only when I was on WCDMA / HSPA.  I hope they rectify the issue soon; I have LTE turned off on my phone in the meantime.  Also helps that I was near my quota for the month

It seems that T-Mobile in some places is suffering from that same circuit fallback issue that Sprint was having with their newer tri-band phones.  When the phone is on LTE, most of the time when someone calls it just goes to voicemail.  I've been having this issue recently and I've seen quite a few threads online with others suffering from the same thing.  At least when Sprint was having this issue the phone stayed on 3g until whatever needed to be fixed on the tower level was fixed.  Annoying.... at least they're working on it.

Washington DC is fun too the city is centered around a star in the basement of the Capitol building.. now granted it was planned that that was going to be George Washington's tomb but hes still buried at mount vernon but the street names bot named that way anyway  so there are four quadrants in dc nw ne sw se 

 

all numbered streets run north south all lettered east west and states are the diagonals.  the numbers of the houses are how many blocks from the capitol.. so 1600 pennsylvania ave nw(the white house) is 16 blocks north west of the capitol(well the star in the basement) but if you go to 1600 pennsylvania ave sw its barney circle down in front of the john phillip sousa bridge...  

 

there is a bunch of other crazy crap in dc lol which makes driving there nuts so do yourself a favor take the metro and dont try... 

Once you know the rules it's not bad getting around the city.  I miss DC... born & raised there and haven't been back in a while.

Man, you're old. I think I was only 30 when that went down.. ah, memories. I remember rooting my EVO Shift (a Windows phone for those of you unfamiliar) to get a hacked-together version of Froyo on it. Even with its limited functionality, I remember thinking it was exactly what I hoped to see on phones someday. Still love it, many desserts later.

 

I have no problem supporting older devices, at least for now. They are actually easier, manufacturers didn't try as much funny business behind the scenes back then, and there was none of this crazy new-fangled LTE stuff to worry about!

 

-Mike

I think that was the Touch Pro, since the Evo Shift was also an Android phone

I noticed on other Sprint phones that there's finally 4G here on UM's campus.  So that's progress.

If there was, it would be in there

 

There is no standard Android method to display frequency information, so I need to create manufacturer-specific "hacks" to get the data. So far, the only success I have had is with the LTE frequency info on HTC devices. Samsung has proven impossible to get extra data from. Hopefully I will make progress on the Nexus 5 when mine is delivered in a few weeks.

 

-Mike

Sweet, good to know.  I don't see the LTE frequency on my HTC when connected to it.  I'm on T-Mo tho.

Ah, gotcha.. my EVO LTE does that as well, and I don't have 4.3 and disabled the Power Saver.

 

 

Thanks! I am most interested to see what the app displays when you connect to DC-HSPA+, so a screen shot of that would be great. When you have a chance, PM me your e-mail address and I will send you something else that will help gather data.

 

Thanks,

-Mike

Is there a way to see what band / frequency we're on with the GSM phones?

I wonder if the Spark icon will be universal or dependent on the particular brand handset you have. The LTE/4G icon is different depending on Sense/TouchWiz/iOS look and version. Is this specifically a Sprint made icon or do the manufacturers put their particular finishing touch on it? I can't see Apple letting just any icon adorn their precious task bar..

I would think every phone except the iPhone will get that Sprint made icon. On T-Mobile I have the One and my wife has the S4 and our 4g and 4gLTE icons look the same cuz that's the branding that T-Mobile has. Up until now Sprint hasn't really had a logo for their 4g services like the other big 3 carriers have and have implemented on their phones.

Interesting that they have that information at that level.

Surprised this hasn't been posted yet: Sprint Spark!  That's what they're calling their tri-band devices.  It also says the G2 isn't getting an update until next year that enables the 3 bands, while the Mega and the GS4 mini will be enabled with an update at launch on Nov 8.  The HTC Max is coming "soon".  Maybe that's why so many are having issues with them.

Also must be practically next to the tower, with a -57 dbm reading.

Yeah true. Actually somewhere here I remember reading the G2 would be the first phone without simultaneous voice & data except for wifi. Guess it was good while it lasted on Sprint.

Yes, currently only MetroPCS support Voice over LTE. Verizon and AT&T have stated they deploy it soon. T-Mobile and Sprint need to work on their footprint first before deploy VoLTE

Oh I wasn't talking about Voice over LTE, but simultaneously talking on the phone and browsing the web via LTE, like the Sprint phones do.

One thing I was surprised with in switching to T-Mobile is that my One cannot do SVLTE; it kicks back to the "regular" 4g.  Are all GSM LTE phones like this?

Where I was impressed was on a trip my wife and I went recently to Sanibel / Ft. Myers area.  We had LTE getting onto Alligator Alley (I-75) then it eventually dropped to 4G.  I saw 2G for a quick second... didn't last for very long.  The whole time we were in Ft. Myers we didn't have LTE but just their normal "4g", but the speeds were still quick.  Checking traffic on Maps, using GPS, or looking up places to eat weren't exercises in patience in waiting for the phone to load.  That gave them some points in my book.

 

To me in a very basic sense they're in similar situations, in that they're rolling out LTE so it's not everywhere yet.  But at least the phone calls and texting are working consistently (and texts seem to be delivered VERY fast).
