Sprint TD-LTE 2500/2600mhz Discussion
WiWavelength replied to IamMrFamous07's topic in Network, Network Vision/LTE Deployment
So, you would have Clearwire/Sprint go band 38 TD-LTE and use only the middle third (2570-2620 MHz) of its BRS/EBS spectrum holdings? Let the other 100 MHz, especially the licensed BRS spectrum, just rot. And never mind that band 38 coincides mainly with EBS middle band spectrum set aside for high power video transmissions. Does that sound like a good plan? AJ -
No, as the British would say, not bloody likely. I put together a spreadsheet of WiMAX carrier assignments. Then, I added in the TD-LTE carrier assignment in Denver. As makes sense, the TD-LTE carrier is in licensed, contiguous BRS spectrum, not leased EBS spectrum. And that does not correspond with band 38. AJ

Teaser: iPhone gets two new models but no LTE band *trifecta* on Sprint
WiWavelength commented on WiWavelength's blog entry in The Wall
Regarding resale, iPhone = iron pyrite. If you do not recognize it, look it up. AJ -
No, that is not *deductive* reasoning. That is *inductive* reasoning. If Sprint said, "All handsets from here on out will be tri band LTE." Then, if the Note 3 were released after that statement, well, deductive reasoning would tell us that it would be tri band LTE. Deductive reasoning is top down. It deduces specific instances from general rules. Inductive reasoning is bottom up. It infers specific instances or general rules from other specific instances. So, to steer this back to the situation at hand, the Galaxy S4 mini tri band does suggest that the Note 3 could be tri band. But the iPhone 5S/5C are only dual band, so there is one caveat. And there are reasons -- SVLTE and/or SVDO -- why the Note 3 could be only single or dual band. Thus, we can inductively infer that tri band is a distinct possibility for the Note 3, but it is not guaranteed Class dismissed... AJ

Maybe. We shall see. But as long as the subsidy system continues, the lockout of other domestic operators makes sense. Deadbeats should not be able to take their iPhones to other providers. AJ -

Give a woman any iPhone. She will not know the difference and will be happy, right? AJ -
I doubt it. I will have to check if CDMA1X Advanced is a protocol revision beyond P_REV 6. If so, then it may show within engineering screens. Otherwise, probably not. AJ

Yes, when I am not tapping out S4GRU articles and posts, I stay in good shape by being taken on frequent walks and fetching thrown tennis balls. AJ

If Apple says, "Jump", Sprint asks, "How high?" I do not like it, but that is just the way it goes because of the iPhone mystique among the unwashed masses. AJ -
iPhone 5S/5C teaser article is already up on The Wall. Give it some love. We dropped all other priorities today to bring this info/analysis to you, and there is more to come -- maybe even later today. http://s4gru.com/index.php?/blog/1/entry-352-teaser-iphone-gets-two-new-models-but-no-lte-band-trifecta-on-sprint/ AJ

Teaser: iPhone gets two new models but no LTE band *trifecta* on Sprint
WiWavelength posted a blog entry in The Wall
by Andrew J. Shepherd Sprint 4G Rollout Updates Tuesday, September 10, 2013 - 1:10 PM MDT To cut right to the chase, Apple announced at its live event today two new iPhone models: high end iPhone 5S and mid range iPhone 5C. Both are coming to Sprint and both support Sprint LTE -- but only dual band Sprint LTE. The new crop of iPhone models for the next year will not be tri band LTE handsets on Sprint. The LTE bands supported by iPhone 5S (A1453) and iPhone 5C (A1456) are substantial and as follows: band 1, 2, 3, 4, 5, 8, 13, 17, 18, 19, 20, 25, 26. For Sprint users, that means dual band LTE 1900/800. While 13 total bands seems impressive, a few of those bands -- such as band 2/25 and band 5/26 -- are subset/superset bands. The big takeaway for Sprint users, though, is that band 41 is absent this year. So, TD-LTE 2600 will be coming soon to several tri band Android handsets but not to the dual band two new iPhone models. Band 38 TD-LTE 2600 is limited to the Asia/Oceania variants. Also worthy of note, Sprint and SoftBank share the same iPhone 5S and iPhone 5C variants this year. Whether that is merely coincidence is impossible to determine. But Sprint and SoftBank have talked about combined economy of scale as a benefit of their tie up. To conclude, the new iPhone FCC OET docs have not yet trickled out, but as they do, we will have more info to come. Stay tuned...

I, too, am querying the FCC OET database regularly today. If last year is any indication, expect the FCC OET docs to start appearing one by one shortly after the presentation is over. So, Josh, you are welcome to keep checking, but I have to do likewise, as I have to write the article for The Wall later today. AJ
