    If that is band 13, it comes as no surprise. It has become the slow lane on VZW; band 4 is the fast lane. AJ

    I know I posted a few months ago something to the effect that the Nexus 5 will have by far the greatest longevity yet of any Sprint LTE handset. Its tri band capability and RF prowess -- not to mention, price -- will keep it relevant for an unusually long time. Screen, processor, and RAM will be surpassed, but those specs have since reached the point of diminishing returns, have entered the realm of "specsmanship." I already have too many handsets, including a white Nexus 5. Yet, I am still tempted to add a red Nexus 5 at some point. AJ

    And that is what has puzzled me about DAS in sports stadiums/arenas. Great for signal strength, poor for capacity. Absent multiple 20 MHz carriers, a single sector for thousands of people is inadequate capacity -- unless the DAS is somehow running multiple eNodeBs through the DAS on the same carrier(s) with the same GCI/PCI. In a previous post, I recall surmising that DAS is mostly about confining the stadium/arena users to the DAS, hence not swamping all of the surrounding macro network sites, too. AJ

    That is a repeater. All it is doing is amplifying the RF from the site down the street. A DAS or a small cell would be a separate site -- with its own identifiers. AJ
  5. WiWavelength
    Nope, not entirely buying that oversimplified explanation. In metro areas, the duopoly's sites are also generally "spaced for PCS" -- even where they have long held Cellular licenses. Everybody now needs that close level of site spacing just for capacity. AJ

    To say that "Motorola and Sprint didn't mesh somewhere along the way with the (2014) Moto X" is too strong a leap in inference. The jury is still out on what will ultimately become of that FCC authorized variant. But, yes, Motorola is a wild card in the Nexus handset game, since it replaces LG after the previous two iterations. We can look, though, to LG for one or two precedents, since Sprint was left out of the Nexus 4 sweepstakes. Maybe that was political -- because, at that time, Sprint did not want to set up a Nexus 4 white list for devices purchased from Google Play. Or maybe it was technical. The Nexus 4 used a Snapdragon S4 standalone processor (APQ8064) that was paired with a worldwide compatible 3GPP only baseband (MDM9615). Right there, that precluded Sprint. Or maybe it was a combination of both factors. In 2012, a Sprint compatible Nexus 4 would have needed just band 25 -- no dual or tri band hurdles to clear. Still, Google and LG may not have wanted the added complexity of the Nexus 4 as an SVLTE handset, which Sprint would have required -- before it transitioned to single RF path e/CSFB handsets a year later.

    It is just a standalone processor, so it has to be paired with a separate baseband. Unlike integrated basebands, separate basebands come in 3GPP only and 3GPP/3GPP2 flavors (e.g. MDM9235 and MDM9635). AJ
  8. WiWavelength
    The Snapdragon 805 processor would not be a direct reason, but it could be an indirect factor. AJ
  9. WiWavelength
    Uh, no, there are plenty of reasons -- both technical and political -- why the Nexus 5 successor might not be available on Sprint. That is why we have to wait and see... AJ

    Somewhere, a psychology grad student is writing a dissertation on this newly observed condition called "T-Mobile fanboi hypocrisy." Read the comments to the Fierce Wireless article. Commenters are actually excited about inadequate PCS only ground mount rural sites. If Sprint had followed the same plan, they would be attacking it with knives. AJ

    The evidence for the iPhone 6 variants is still inconclusive. But all iPhone 5 variants operate in slotted mode -- that is the only way for a non e/CSFB handset to idle on a CDMA1X network. Furthermore, waking and listening to the paging channel per the synchronized slot cycle index is the very definition of a handset idling on a CDMA1X network. AJ

    An idle CDMA1X mobile does not "ping" the network. In slotted mode, it "wakes" every few seconds and "listens" to the paging channel. And probably 99 percent of the time, there are no pages directed to the mobile during that slot, so it goes back to "sleep." AJ

    A -110 dBm signal on band 25 is not any more "weak" or "bad" than the same on band 26. Both are at the same signal level. The band/frequency has already been taken into account in the path loss the signal incurred. AJ

    Iusacell is a bad brand name. It reminds me of the low rent apartment complex, Awana Place. AJ

    Is that what she said? I did not know that your Nexus 5 was a girl. My Nexus 5 is definitely male. I do not have any girl phones. AJ

    And monkeys may or may not fly out of my butt. Honest truth. A "may or may not" statement might as well be left unsaid -- because the substance of the assertion is practically zero. AJ

    What is this "answering the phone" of which you speak? Anyone who calls me can talk to my voicemail. In fact, voicemail may be my best friend. If I won a free boat ride for three, I would invite my voicemail and Robert -- or maybe T-Pain. AJ

    Take advantage of or add support for which capability? AJ
  20. WiWavelength
    What do you want to know? There is not much to report. Sprint tri band handset FCC OET docs are becoming a bit boring: tri band LTE, e/CSFB, etc. We are reaching LTE device maturity already. Band 41 carrier aggregation is the next frontier, I suppose. AJ
  21. WiWavelength
    That is almost the ideal setup for a sexual joke, but I will refrain. I will add, though, that my Nexus 5 came with a SIM release tool. So, where is your tool? Can you not get your tool up and put it in that slot? AJ

    I wish I knew more about the USCC network. You would think I should, especially as USCC, former WWC footprint starts just 15 miles from me. But I do not have that much knowledge of the USCC LTE network. I have used only its CDMA2000 network. I can say, however, that USCC handsets have been consistent in supporting SVLTE -- for better, for worse. We know that SVLTE has end user benefits and RF performance detriments. But, to provide an example, we know that the Samsung Galaxy Note 4 "P" variant for Sprint is as expected this year: tri band, single RF path e/CSFB. The regional operator "R4" variant, which I commented on earlier today, is band 2/4/5/12/17 and supports SVLTE. The latter seems to be a consistent feature -- iPhone excluded -- on USCC. AJ

    Likely, many of these WiMAX MVNOs will simply close up shop. Their business model will have failed. That is why notice may be limited. AJ
  24. WiWavelength
    Robert, are you sure about that? I was going to tell RichardXy that we did not want time at The Forums to keep him away from kicking a few dogs on the way to cash his check. AJ

    The dichotomy between T-Mobile and Sprint reminds me of a scripted scene in Oliver Stone's "Nixon." Anthony Hopkins, playing the soon to be deposed Nixon, looks up at a portrait of JFK in the White House and says, "When they look at you, they see what they want to be. When they look at me, they see what they are." T-Mobile is a cult of personality. People are excessively positive about T-Mobile, excessively negative about Sprint. People give T-Mobile the benefit of the doubt, pleased with the present and supremely confident about what the future holds. People hold grudges against Sprint, displeased with the present and obsessively cynical over a negative past. But both of those are far more flawed human perceptions from failed people than they are actual objective assessments from rational individuals. For example, what happens to T-Mobile's financials when it has to increase its CAPEX for its long, long, long overdue rural network modernization? Sprint has already taken care of that, is years ahead of T-Mobile in that regard, and probably has "disrupted" T-Mobile into finally getting its rural ass in gear. And what happens to T-Mobile's financials when it has to spend billions to acquire Lower 700 MHz and/or forthcoming 600 MHz spectrum? Again, Sprint has already taken care of that. Hypothetically, Sprint could walk away from the 600 MHz auction -- should the auction ever actually happen -- and still have nationwide low band spectrum. T-Mobile does not have that luxury. While Sprint has already paid its low band bill, T-Mobile has barely even started. As Robert notes, it is still very early. The cult of personality will not last, just as the "Camelot" White House came to an abrupt end -- to draw another JFK parallel. And T-Mobile -- or whatever becomes of the pink "un-carrier" -- eventually will be left holding the bag. AJ
