    We do not know, but coverage over projection has been a problem from the very beginning. Some of us surmise that Sprint could be equipped to map based only on RSSI, not RSRP. Thus, LTE coverage is being depicted down to something like -119 dBm RSSI. But who knows??? AJ

    Like the "Trench coat Guy" for Sprint," the "Can you hear me now?" guy for VZW, and Chad for Alltel, Cox should run commercials with a corporate pitchman. Call him "Mike Oxgood." AJ

    Agreed. Now, comment to Legere about his LTE and W-CDMA "neverland," and he will make some boastful comeback that the T-Mobile fanboys will eat up. AJ

    Just waiting for John Legere to call it Sprint LaTE... AJ

    If your use is heavy and battery life is holding up so well, have you found love with the new Nexus 7? And if so, what are you going to do with it? AJ

    Wait, Robert has already experienced TD-LTE in Denver. Did we track any EARFCNs to see if Clearwire is using the same or different TD-LTE center frequencies? Oh, what was I thinking? AJ

    To put it another way, just one contiguous 20 MHz segment needs to be identified or cleared per sector for TD-LTE. And it does not need to be the same 20 MHz on every sector. So, the initial TD-LTE deployment will not take much in the way of spectrum resources. AJ

    The battery life/power management on the new Nexus 7 is out of this world. Mine has been off the charger since its inaugural charge 48 hours ago, and even with moderate usage, battery is still at 60 percent. AJ

    To add to that, the obsession some have with the latest official Android release is borderline insanity. Folks, Android 4.3 is not going to change your life. And you are not deprived if you are still on Android 4.2. So, as a suggestion, relax and do not worry about it. AJ

    Cleveland is a far different situation. Yes, it is inside the IBEZ, which is based on the position of the international boundary. However, actual landmass Canada is all the way across Lake Erie. And that is why Sprint has somehow gotten special dispensation to deploy CDMA1X 800. Contrast that with Buffalo. It is also inside the IBEZ, but the most populous region of Canada is right across the river. That is not even remotely like the Cleveland situation. Barring a miracle, Buffalo is out of luck unless/until a new treaty is worked out with Canada -- assuming that is even possible with Canadian public safety and Telus Mike iDEN operating right across the border in places such as Niagara Falls and Windsor.

    I take it you are pulling the EARFCNs, then running the calculations to produce the center frequencies. Or did you find the device is reporting center frequency data directly? Either way, good work. And it becomes important as Sprint starts refarming its PCS A-F block spectrum for LTE. The first time that a single band LTE device user encounters an EARFCN other than the PCS G block 26665/8665 (1912.5 MHz x 1992.5 MHz) will be a notable occurrence. I wonder if you could incorporate a user alert into the app or even have "E.T. phone home" with a log sent back to you on such an occasion. I wrote an article a year and a half ago about a second 5 MHz FDD LTE carrier in PCS A-F block spectrum. It identified the most feasible candidate markets. http://s4gru.com/index.php?/blog/1/entry-27-spectrum-analysisdoes-sprint-have-more-options-for-additional-lte-carriers/ AJ

    As I said, less robust, unequal per user. AJ
  13. WiWavelength
    As a ratio, 21:12 is a lot smaller than 21:1. Get my point? Newer airlinks do not create greater capacity through magic. Rather, they tend to trade off reliability, robustness, and per user equality for higher peak speeds. AJ

    For greater than -40 dBm, maybe the icon message should read: PUT THE PHONE DOWN AND STEP BACK FROM THE ANTENNA! AJ

    Neal may need to be careful what he suggests. If economic forces mean that Sprint must convert fully to the 3GPP side of things in the next few years, then it will likely just acquire Neal's beloved T-Mobile -- as many already think Sprint will do. And that will present the easiest transition opportunity, since T-Mobile will bring to the table a preformed W-CDMA 1900, W-CDMA 2100+1700, and LTE 2100+1700 network. Move Sprint subs to T-Mobile's W-CDMA network, then refarm CDMA2000 to W-CDMA and LTE. Additionally, Sprint gets back into the AWS game, which Neal seems to think is so vitally important. So, if we are making unpopular prognostications around here, well, there you have one... AJ

    No, I mean hyperbole. AJ
  17. WiWavelength
    ...or would that symbol be only for a roaming signal greater than -50 dBm? AJ
  18. WiWavelength
    I probably would not recommend that. In most instances, your handset has to deal with signals that are up to 80 dB (100,000,000x) weaker. Subjecting it to a -25 dBm signal might overload its RF front end. AJ

    OFDMA and all IP -- those are the real dictates (or what they should be) for "4G." WiMAX meets them. HSPA+ does not. It is not OFDMA, and it still supports circuit switched voice. Basing "3G," "4G," or whatever "G" on speeds, potential speeds at that, is just plain stupid. AJ
  20. WiWavelength
    Maybe above -40 dBm, instead of displaying the numerical signal level, it could display a message: DUCK AND COVER! AJ
  21. WiWavelength
    Inappropriate for WiMAX, no. Inappropriate for HSPA+, yes. AJ
  22. WiWavelength
    Yeah, but in about a gigahertz of spectrum bandwidth. AJ

    Once CDMA1X 800 goes live, you may be screwed. If this has disabled automatic band selection on your EVO LTE, then you will be unable to connect to CDMA1X 800 + LTE 1900 simultaneously. Effectively, you will have to choose between CDMA1X 800 by itself or CDMA1X 1900 + LTE 1900. Additionally, when roaming, you will have to choose the appropriate band for the particular roaming partner. AJ

    This is a thread on the public side of The Forums. Do not post site IDs outside of the sponsor side. That is why another moderator hid your post. AJ

    Airlink selection in the Testing.apk menu is fine. That has no permanent effect. Band selection, on the other hand, may wreck automatic band selection. AJ
