Looks like at&t has already started deploying lte on band 5 with 5 mhz channels. 

 

 

Why are speeds so low, and pings so high with full bars on a new LTE channel?

I'm sorry maybe I'm blind, but I'm seeing reports of Band 17 with 5Mhz channels.

As an addendum, AT&T holds no paired Lower 700 MHz spectrum in CMA250.  USCC holds both Lower 700 MHz B and C block licenses.  The only Lower 700 MHz spectrum AT&T holds in Bloomington-Normal is the unpaired Lower 700 MHz D block.  So, there is the definitive reason for 5 MHz FDD band 5 LTE 850.

Ah this sums it all up. Danke! :)

Makes sense.  AT&T should be seeking for opportunities to refarm it current spectrum for LTE instead of trying to hoard spectrum.  They have plenty of spectrum when all things are considered.  Hopefully Verizon will refarm its 850 MHz spectrum for LTE.

I'm pretty sure it would make more sense for Verizon to refarm their 1900Mhz spectrum since they have nationwide 700c almost fully deployed. 

After AWS i'm betting on PCS being refarmed.

So for voice ATT is using pcs? Why the rush to refarm when HSPA can give you decent speeds AND voice?

 

They will leave 5Mhz of HSPA+ and refarm 5MHz for LTE. 37Mbps vs 14Mbps (AT&T never went for the 21Mbps flavor). I would take that tradeoff.

Maybe.  But VZW does not have the same level of PCS holdings that the other big three do.  New York City is really the exception in that regard with 40 MHz of PCS.  In so many other markets, VZW has only a single 10 MHz PCS license.  At best, that would buy VZW only an added 5 MHz FDD band 2 LTE 1900 carrier.  What does that really gain?

Why do you need to bet?  OH you must not have heard that Verizon is already planning to refarm PCS for LTE in 2015.  I made a topic about this before back in June.

Seen FierceWireless article when it came out. That's not really the point...

The point is that Verizon has low band 700c spectrum for coverage laid out already across the US. In places where they need capacity and don't have AWS holdings, it would make more sense to deploy mid band PCS which has similar propagation characteristics. Especially with the introduction of CA and small cells.

 

Now as AJ just pointed out, there is another issue, and that is lack of significant PCS in many markets.

Good that you saw the article but why bring it up in the first place if you knew?  To me the Fiercewireless article pretty much implies that Verizon will deploy LTE on PCS after AWS. 

 

Verizon pretty much has nationwide AWS holdings. Of course some markets have more than others.  But my point still remains that ATT and Verizon still need to refarm their 850 MHz holdings at some point.

Why bringing it up? Because it makes more sense refarming mid band spectrum after you've already blanketed the entire nation with low band LTE, taking care of coverage. Common sense, no? So you're right, according to Verizon AWS is next, and PCS is to follow. Not CLR. 

Voice is mostly on 850Mhz which is another reason why it wouldn't make sense to start shutting that down too soon.

Eventually they will use 850Mhz spectrum for LTE, but they're in a completely different position than AT&T and are definitely not in a hurry to refarm 850Mhz spectrum for LTE...

Are cell companies allowed to upload/download on different frequencies such as upload on 1900 Mhz and download on 700 Mhz at the same time?

 

Yes, to an extent.  But a carrier aggregation pairing of a PCS 1900 MHz uplink and a Lower 700 MHz downlink would not be a great combination, as it would not really take advantage of 700 MHz reception characteristics.

T-Mobile uses their 1700/2100 Mhz for upload/download combination.

Do they do that because they are required to, or because they want to?

 

Maybe a 700/850Mhz combination would be better paired?

 

T-Mobile doesn't have a choice, nor do AT&T or Verizon or any of the smaller carriers on AWS  - that's just how the AWS spectrum was paired by the FCC

AWS spectrum is paired spectrum with a 2100 MHz downlink block and 1700 MHz uplink block. So when people refer or say "AWS" or "1700/2100 MHz" spectrum, they are basically saying the same thing. 

 

The 1700/2100 MHz blocks were assigned by the FCC to pair these 2 spectrum blocks together for auction.  The 1700/2100 MHz spectrum blocks were not pulled out of thin air and are not random.

 

Also you can't pair 700 and 850 MHz together since they are completely separate band classes.  700 and 850 MHz spectrum each have their own paired spectrum blocks.

Although I had heard it before, I never thought how much of spectrum disaster att has. It has to lead to very inconsistent experience for customers from market to market.

How is T-Mobile using just 1700 Mhz for LTE, for both upload and download?

 

Unless this table listing 1700 Mhz also assumes the paired 2100 Mhz band?

 

thanks

You're absolutely right about their spectrum. Their UE requirements have changed to Band 2, 4, 5, 17 after they've divested large chunks of their AWS spectrum to T-Mobile. And since they don't really have nationwide lower 700Mhz paired spectrum either, they have to deploy LTE in other three bands. Perfect example is Bloomington, IL where they're introducing Band 5.

 

As far as user experience, I don't think it should matter that much as long as your AT&T branded device supports all four LTE bands.

Does AT&T own both A and B cellular bands in Bloomington? Where would their voice traffic go?

    • Almost at 76% licenses "sold" at $160 million. Like watching paint dry.  Will check again in a few days. 
    • I guess we'll see how many takers there are for this: https://www.bloomberg.com/news/articles/2022-08-04/dish-nears-launch-of-mobile-service-taking-on-at-t-and-verizon One early drawback to the Boost Infinite service is that, for now, subscribers will need to buy a $900 Motorola Edge+ phone to get connected to Dish’s new network. More phones that are compatible with the system are expected in the third quarter, Dish told analysts Wednesday. Registration Site: https://www.boostinfinite.com I remember when Virgin Mobile went iPhone-only: https://techcrunch.com/2017/06/21/virgin-mobile-goes-iphone-only-offers-a-year-of-service-for-1/ That didn't go so well.
    • Hey Mike    Ya I was the one that brought the issue to your attn for the color thing on my 6T like 3-4 years ago   that was fixed after like 6 months  and I never had any issues with that anymore till the 1st  Android/OxygenOS 12 update but it hasn't done that anymore (that i've seen lately)   it just doesn't give me the  signal strength much anymore  it'll show it for like 5 mins then  switch to  "--"  and stay that way  Sometimes if I close it out and reopen it  it'll come back (tho the icon is delayed showing up for like a min  or so when it used to show up instantly) but after a few mins it's back to showing "--" again and other times it'll just come back to the "--"
    • Sounds like an awesome project—keep us posted on how it’s going! Also—if you’re able to figure out logging, I can work with you to get the data uploaded to SignalCheck. 
    • Yesterday, I saw a post on Facebook from an old friend about the Evolve III Maestro, a $60 laptop (at Micro Center) that apparently has an LTE modem in it.  Specifically, the Quectel EC25-AF*.  The nearest Micro Center was sold out of new ones, but offered open box at $48.  So for $51 after tax, I walked out this morning with one.  An absolute steal. I backed up the Windows product key and then put Kubuntu 22.04 on it.  I spent a lot of time today trying to get the build tools installed so I could get the wifi module installed and running, and once I did that, I pretty quickly got to sending it modem commands, which I've never done before.  I don't have a SIM in it yet, but it does seem to function as it should.  (I figured out the command to get Timing Advance values out of it, but without a SIM, I doubt it would have such values.) Now I'm trying to puzzle out how to write some kind of script or small program to use it for logging purposes.  I think I've worked out how to send commands to it from bash using socat, but I need to pick specific commands to run.  I'd actually like to replace some of my phones with this if I can get it to record cells, with GPS, and cycle through a set of bands repeatedly.  My current phone collection consists of 9 phones other than my main S21FE, and they require babysitting while I'm logging.  It'd be nice to pare that down to a more reasonable number and let the computer do the work, hopefully in the back seat with less babysitting. - Trip ===== * Per the spec sheet, it supports B2/4/5/12/13/14/66/71.  That'd cover all of Verizon and US Cellular LTE, all but B29/30 on AT&T, and all but B41 and Sprint Keep on B26 for T-Mobile.
