2500 and 2600 are the same LTE Band. LTE Band 41. Some people call or 2500, and others call it 2600. They're pretty interchangeable. EBS is mostly in 2500 and BRS is mostly in 2600, but both are combined into one LTE band.

Wrong. 2600 refers to Band 7, while 2500 refers to Band 41 (according to frequency indication conventions).

 

Since you started it...

 

Wrong!

 

LTE Band 41 is a TDD band from 2496 - 2690MHz. It's the same as WiMax. It's a roll up band for the 2500 and 2600 that includes the EBS band and BRS Band.

Upon re-reading, maybe you're referring to unofficial naming nomenclature, like in the way people refer to Cellular as 800, but better described as 850.

Yeah, that's what I'm referring to. It's partially determined by middle downlink frequency, but not always.

Thanks for the clarification. I initially read your post to say that Band 41 did not cover 2600MHz at all.

Ok... sorry but does the above info from my post indicate that GS4 ACTIVE will be tri-band?

The Galaxy S4 Active supports the following:

GSM 850/900/1800/1900

UMTS 850/900/1900/2100 (bands V, VIII, II, I)

LTE 800/850/900/1800/2100/2600 (band classes 20, 5, 8, 3, 1, 7)

 

The AT&T model swaps UMTS 900 (Band VIII) and the LTE band set for:

LTE 700/850/AWS/1900/2100 (band classes 17, 5, 4, 2, 1)

 

So, no. This device is useless with Sprint, since it doesn't even operate a UMTS-1900 (band II) network or a LTE band 2 network, much less an LTE band 7 one.

 

Also of note: if a device supports both 2500 and 2600, then it supports bands 38 and 7, not bands 41 and 7 (normally). At this moment, there are no parts that support BC 7, 38, and 41 simultaneously. Band 7 and 38 can be supported, or Band 41 can be supported.

Eh, I question that, as I have not seen any official documentation.  And even if there is official documentation, I would call it baloney.

 

For me, I have standardized on 2600 MHz because it is closest to the center of the band.  Call it a happy medium.  But I definitely agree with Robert that people use 2500 MHz, 2600 MHz, 2.5 GHz, and 2.6 GHz all interchangeably.

Personally, I use 2.6GHz to refer to all three bands, but unofficially the official denotation for Band 41 is 2500. The official denotation for Band 7 is 2600, and Band 38 is undecided, though leaning toward 2500 as well (though handsets that support 2500/2600 are referring to Bands 38+7 being supported). Using frequency indicators is a rather annoying way to determine banding for devices, though...

 

Parts that support Bands 38+7 and 41 simultaneously are coming, though. Fairly soon, the frequency/band class thing may become merely an academic thing.

Well, I like to think that I have a knack for sensible naming conventions.  I long ago decided on band 41 TD-LTE 2600, and I am sticking to it.

 

I used to refer to WiMAX 2500/2600 and BRS/EBS 2500/2600 MHz.  The problem with the latter, though, is that it sounded as if BRS is primarily 2500 MHz and EBS is primarily 2600 MHz.  However, the opposite is the case.  So, I had to choose, and 2600 MHz just made more sense.  Otherwise, a TD-LTE carrier could be at the high end of band 41, nearly 200 MHz removed from 2500 MHz, and that just would not make sense from a naming perspective.

Or we can call it what I once heard Bob Azzi call it, "Two dot six."   :lol:

Just got told that, as the Tri-Band S4 gets produced, it will start replacing the original S4 in inventory as it gets rolled out, and nobody will see a difference in packaging, etc. Somehow, this seems like a phenomenally bad idea. I also don't think it's true, as this was "water cooler" talk. Take it with a bucket of salt.

 

Its sounding like there is a possibility of a Sprint Galaxy S4 to support tri-band LTE?  I hope this is true but then again I don't know if Sprint has had any track record of releasing an updated version of a device.

My guess is that it is actually a Note 3 being tested... maybe under the cover of GS4?

Maybe, maybe not. I though that Qualcomm was only in the US. Then again, I didn't do much research. I hear the 800 is a beast, though.

I'd rather see Sprint update the HTC One, and/or get an Optimus G Pro with tri-band LTE. 

I agree.  I'm feeling the One but I wouldn't want to get that and then not be able to use LTE 800 if it comes out in my area within 2 years.

 

I don't want to be a tester for first tri band device.  Ill wait a year just like most electronics they have to fix real field problems

That thought crossed my mind too.  I don't really want a repeat of the Evo LTE issues with my next phone.

Good idea there. I need to wait anyway I have a note 2 so it will be awhile before I can upgrade again.

 

I'm assuming we all mean 3 LTE bands not just PCS, 800 Mhz CDMA, and 2600 TDD LTE.

To further that link here is another showing it will support carrier aggregation.

My upgrade is august 1....

 

I really hope a tri band is out by then.

 

And that its the active.

 

The active has a replaceable battery right? Is the processor same as the standard G4 or is it gimped?

 

Doubt it. The next flagship phones are due in oct and nov. I can upgrade now and it pains me that i have to wait until Oct for the note 3 since i want that tri-band lte support.

Just saying, the last 2 years, Motorola has released a Sprint device around October, so we'll see if Google's ownership makes an impression on this year's device.  The last 2 years has been Motorola handling things, itself.

 

I'm expecting a late October/Early November for the next flagship.  May even be the Note III.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
