3G -> 4G carriers down the road

A couple things, Sprint has spare spectrum in their PCS A-F holdings right now, that could be purposed for an additional 5x5 carrier. I suspect they will look at doing this after they complete the first phase of Network Vision.

 

This is a great read by wiwavelength explaining this.

Sprint absolutely can repurpose 3g to 4g if demand for LTE increases and EVDO decreases.

 

Finally I believe one day in the mid term future they will turn EVDO off and just have 1x/LTE.

There are not many areas with spare carriers just laying around. Some rural areas previously only had one data and one voice but now after NV with little effort they can do 4.

 

Are we talking actual spare carriers? Or are we talking spare spectrum that could be used for additional carriers? In the case of the latter, Sprint has 10-20 MHz of spare spectrum on many, many sites that could be used for additional carriers.

To spring board off AJ a little here...

 

To clarify, an EVDO carrier cannot be converted to LTE use. However, once EVDO carriers are deemed not needed any more, they can be turned off. Once there is enough EVDO carriers decommissioned to free enough spectrum for one LTE carrier, then one could be added.

 

However, in most markets, there is already room for one additional LTE carrier at most sites in PCS Block A-F. This can be added to supplement the G Block carrier when capacity is needed.

 

In markets where there is not much spare PCS spectrum (like Chicago, Ft. Wayne and Houston), they cannot add additional PCS carriers now without clearing some unneeded EVDO carriers in the future. Well, at least not now. Chicago and Ft. Wayne will have additional PCS spectrum coming from USCC in the next 24 months or so. But Houston is a problem. And probably a few other markets.

 

Also, even in spectrum constrained markets where it appears that there is no capacity, note that not every site has the maximum amount of EVDO carriers deployed. In Chicago, only about 10% of sites are maxed out. So it is possible to add LTE capacity at sites where there may be enough spare EVDO capacity, so long as those sites are far enough away from EVDO sites on the same channel as to not cause interference.

 

Lots and lots of options here. Varying by market.

Sprint needs to stop farting around and secure some more PCS spectrum. Leap comes to mind, so does Metro....

Good stuff guys... <br /><br />Just being curious on the subject matter, how's columbus, Ohio on spectrum

 

Columbus is fine. It is a PCS A-F block 30 MHz total market. A few years back, Sprint was limited to 20 MHz in Columbus but acquired a PCS C5 block 10 MHz disaggregation to supplement its holdings.

I was really wondering if they might do just do 1x and LTE someday. 3G travels a little further and the way some people hate change I bet 3G will be around for a long time. Longer than most would think using up space that could be used for LTE to keep those who hate change happy.

Hold up. Sprint still has SoftBank and Clearwire to get approved. Those are priority #1 and #1a.

 

Do not bite off more than you can chew. Otherwise, you might end up choking. AT&T learned that the hard way.

If you mean EV-DO, please use that terminology. "3G" is a generic moniker that, like "4G," has lost basically all of its meaning.

Ok for my last few posts 3G=EVDO. I thought it was Sprint's only 3G.

AJ, you know how I feel about Clearwire. I'm not sure that I really like the all that spectrum and even the network that they bring in. How does Clearwire's network integrate with Sprint's. What are they going to do with all of Clearwire's sites and leases? I personally believe that Sprint should actually just get their BRS spectrum back from Clearwire and let Dish have the rest. I think they should have gone after both Metro and Leap last summer. Heck, I would like to see them acquire USCC as well. But then I'm just a forum jockey.

The EBS spectrum that Clearwire has leased has little value compared with BRS. So "just sell it to Dish" doesn't really net them any big benefit.

 

Also, a huge draw for SoftBank to Sprint is the ability to gain an economy of scale on TD-LTE in 2500/2600 spectrum. Without that, Sprint probably wouldn't be buying CLWR right now, nor would SoftBank be buying a significant chunk of Sprint.

 

Plus, keep in mind that Sprint's spectrum issues are in a few selected urban areas. Two of those areas (Chicago and Houston) have full-blown Clear WiMAX networks. Overlay TD-LTE and your spectrum issue pretty much goes away.

 

As far as MetroPCS goes, Sprint tried buying them. The deal fell through. As for CricKet, there would definitely be synergies with Sprint, mainly on the spectrum side (or, you know, just dump all CricKet customers onto Virgin Mobile and call it a day). However Clearwire is the more strategic purchase, since we're talking about a nationwide deep spectrum overlay rather than a bunch of markets with a smattering of PCS and AWS. If/when CricKet gets bought, Sprint would need to figure out what to do with the AWS spectrum, and T-Mobile has too much going on right now to give Sprint a good deal on a swap.

Unless Sprint deploys 2.6GHz on all their sites, they will not achieve scale. Heck, China Mobile is going to deploy TDD-LTE on 200,000 sites. Clearwire will deploy to 5,000 at least according to current plans.

 

Sprint has spectrum issues in more than those two areas: Off the top of my head they have problems in Florida and the San Fran area. The Wimax coverage in both areas leaves a lot to be desired. I have not experienced the Wimax in Houston or Chicago, but if it is anywhere near the experience in Orlando or Jacksonville then, sorry I don't buy it. Yes they will deploy LTE on 800MHz and 1900MHz and of course on 2.6GHz, but 1900MHz is their bread and butter frequency and I feel they should have a 15x15 or 20x20 LTE allocation on 1900MHz everywhere. Now they might be able to achieve that between PCS G, PCS H and A-F, without acquiring anybody. But I also want them to grow their user base.

 

The reason I suggested that they just take the BRS spectrum and run is that unless they have TV ambitions, 60MHz on 2.6Mhz is more than enough spectrum for hotspot duty. It also might not trigger a spectrum screen where as 160Mhz might.

 

The other reason I want them to sell Clearwire minus the BRS spectrum is that Clearwire+Dish will be seen as a viable 5th nationwide competitor and might make it easier for the FCC to approve a Sprint/T-Mobile merger, which I know it's being looked at.

Could the EU's pending LTE 800MHz band be compatible to Sprint as a 'World Band' much the same as 2.6GHz ?

 

http://www.mobilewor...29a6cb360153ab7

 

 

Under the European Commission’s Radio Spectrum Policy Programme (RSPP), all 27 EU member states should have made the 800 MHz band available for mobile broadband services by 1 January 2013. However, at the time of writing, only nine countries have confirmed that the digital dividend spectrum has already been assigned, with the remaining 18 countries having announced that they would not meet the deadline, most of them requesting policy derogations.

    • 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. 
    • More bizarre.  I just updated my other Ace without issue. - Trip  
    • Looking over the data so far, bidders can go back and reopen bidding on licenses that appeared settled. In the list below, not all counties are listed and only states with excess demand.  Typically 3 licenses per county for rural areas and some urban areas. Here is how many licenses per state had demand greater than supply: State count AK 3 AL 14 AR 3 AS 6 AZ 9 CA 12 CO 76 DE 6 FL 10 GA 66 GU 3 HI 3 IA 99 ID 47 IL 39 IN 43 KS 231 KY 23 LA 14 MA 5 MD 16 ME 1 MI 86 MN 9 MO 79 MP 12 MS 73 MT 69 NC 26 ND 109 NE 18 NH 13 NJ 6 NM 51 NV 24 NY 13 OH 29 OK 9 OR 30 PA 24 PR 25 SC 20 SD 83 TN 76 TX 236 UT 49 VA 22 VT 5 WA 65 WI 59 WV 26 WY 29
    • Looks like Dish has already taken back the 5x5 of n71 they leased to T-Mobile, and instead of narrowing NR here T-Mobile has gone for broke and made 600 NR-only. They can afford to do that here thanks to B12, and don't need to do that west of here because they weren't leasing 600 from Dish. Does mean that Dish is 10x10 for n71 here (which explains the 30ish Mbps upload peak I saw yesterday). Darned speculators hogging the remainder of the band So T-Mobile is running 140 + 15x15 MHz sub-6 NR here. AT&T is 40 + 15-45x15-45 (15x15 n5, occasional 15x15 DSS on n2 and/or n66 though I haven't seen both in the same area). VZW is 60 + 15x15, with the latter being n2 DSS. Wonder how soon VZW will try n48.
