US Cellular Galaxy SIII LTE Bands

I know that the Galaxy S Aviator (uscc droid charge) had a plethora of LTE bands. Is that still the case with the Galaxy S III? I only ask as it could point to roaming agreements and the possibility of including multiband LTE radios in future Sprint phones.

Funny you mention that, I was just reading about the different GS3 variants on the wikipedia page :)

 

US Cellular is the SCH-R530 model and supports 700, 1700 (AWS) MHz for 4G LTE.

The USCC Galaxy S3 was later than the other carrier variants in hitting the FCC OET. I tried to search it out a few days ago, but the authorization was uploaded just yesterday, apparently.

Only partly correct. In full, it supports both 5 MHz x 5 MHz and 10 MHz x 10 MHz LTE bandwidths in bands 2/4/5/12 (i.e. PCS 1900 MHz, AWS 2100+1700 MHz, Cellular 850 MHz, and Lower 700 MHz). Other than the LTE channel bandwidths, the LTE bands covered are the same as in the Aviator.

Man, that's hot. :P

 

Now with FCC approval, the only thing to stop Sprint from including LTE 800 in their devices is just perhaps the OEMs. Its hard for me to imagine that they will wait until next February to start cranking out LTE 800 capable devices.

The Aviator was a nice harbinger, but the Galaxy S3 really drives the point home. USCC, a regional carrier, has been able to get Samsung to build a custom version with fully three CDMA2000 band classes and four LTE bands yet brings it in at the same size and subsidized price as the Galaxy S3 variants of the national carriers.

 

So, when the time comes, rest assured that Sprint will be able to get LTE 800 and TD-LTE 2600 aboard, no problem.

Dare I even broach the subject, but there probably will be some kvetching now that the Sprint variant Galaxy S3 does not support LTE 800 but surely could have done so.

Its a legitimate criticism now. I think Sprint would tell us that the FCC approval is too new that it was too late to get LTE 800 in these recent devices. And the ecosystem may be too immature to slap TD-LTE 2600 in a device right now. But come Fall, they wont be able to hold either of these excuses any more. They need to get cooking on it with their OEMs. There are a lot of people on the fence waiting to hear about LTE 800 devices.

I just got a sneaking suspicion that it has something to do with iPhone so they sell more iPhones with it being the first 800/1900/2600 device, but everything I have read would say that I am wrong in that. I don't think they are all about making multiple models and if they put multiple LTE bands in the device, it will be 700/AWS/PCS.

I will just about bet my bottom dollar that the next iPhone will be partly but not fully compatible with Sprint's Network Vision plans and/or Clearwire's TD-LTE overlay. Basically, it will lack something, be it CDMA1X 800 or LTE 800 or TD-LTE 2600. And I am okay with that, even silently hopeful for that, since it would give the rest of us a potential network refuge from the iHordes and the congestion that often comes in their wake.

What do you think it will be that it is missing? I am thinking it would be the LTE 800 - with China Mobile doing TD-LTE 2600 I would think they would want to include that.

Since the USCC LTE devices have 4 LTE bands I don't see why Sprint and others couldn't make quad band phones for themselves and their roaming partners. If 800 will be a universal international band it would make the most sense to me if the 800 radio could scale from smr to cellular to international 800. I don't know what the technological hurdles for this would be.

 

Never the less, seeing that these types of radios are possible debases claims by the likes of VZW and AT&T who refuse to allow roaming on the basis of technological incompatibility.

 

EDIT: One possible reason Sprint did not request that Samsung include the radio is that because Sprint didn't expect SMR LTE to be approved so quickly by the FCC, they didn't bother requesting it for fear that a model with an SMR LTE radio wouldn't pass FCC authorization. It also is possibly a contributing factor that SMR LTE hasnt been field tested, which might be a road block for ordering the OEMs to make an SMR LTE phone. It is notable that the EVO 3D received an SMR 1xAdvanced fairly early, late June of 2011. Sprint was only cleared for CDMA in the SMR in May of 2011.

 

If my memory serves me right, Sprint expected SMR LTE to be cleared in August so it may not be an unreasonable assertion to claim Sprint might start churning out LTE 800 devices in September.

As pointed out above, it probably is too soon after FCC approval to expect LTE 800 devices in the very near future. I think Fall is the earliest. I can tell you that 30 days ago, Sprint wasn't planning LTE 800 devices until Q1 2013. But I don't see why they'd wait that long at this point.

I may be way off here, but Sprint did start launching devices that support 1x 800 well in advance of its deployment (such as the EVO 3D, SGSII, and even a couple others, I believe). So, I am hoping they do the same with LTE 800.

USCellular should enable SMR support in their phones and get a roaming contract for at least CDMA, and LTE too since it looks like this phone already supports LTE on 850.

 

850 is the cellular spectrum that Verizon and at&t mostly use. SMR is lower 800Mhz, different band class from 850Mhz

Sprint phones right now support CDMA over 800 and 850 on one antenna, correct? Why couldn't the same be done for LTE? I think that would be a nice roaming partnership for US Cellular and some extra change for Sprint. I just noticed that US Cellular had an antenna in this phone for LTE over 850, and this idea came to me.

I think it depends on the antenna and the radio and the paths. You'd need a radio that supported SMR LTE, then you'd need that to an antenna that supported SMR.

    • 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).
    • 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.
    • 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. 
    • 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.
