    The Wii U has shipped! AJ

    Not really. Much of the Army Corps of Engineers lake and reservoir construction 50 years ago was a reaction to urban flooding in the 1950s. The lakes and reservoirs were designed to hold back floodwaters that would otherwise enter the greater Missouri-Mississippi River system. AJ

    If I am not mistaken, VZW's default codec now is EVRC-B. That may explain why VZW's voice quality is generally lower than that of Sprint, which still defaults to standard EVRC. Newer codecs do not necessarily bring better quality; rather, they bring greater data compression with acceptable quality. I believe an old enough handset on T-Mobile can still use even EFR, which is a fixed rate codec equivalent to the highest variable rate in AMR-FR. AJ

    To add a minor correction, EDGE is a data standard, an 8-PSK modulation enhancement to GPRS. It has nothing to do with GSM voice quality. AJ

    I am a geographer, but I will admit that I can barely keep track of all of the major man-made lakes and reservoirs in Kansas and Missouri, let alone Oklahoma. The Army Corps of Engineers really went overboard about 50 years ago. AJ

    Is the "Victory" really deserving of that moniker? Could we rename it the "Good Effort" or maybe the "Near Upset Victory"? AJ

    ...and thus closes the book on the one way in which Sprint Galaxy Nexus owners are lucky. AJ

    No. This is not TV or radio broadcasting. In urban/suburban areas, cellular signals are rarely designed to propagate farther than 2-3 miles. Deployment in McAllen, Mission, or Edinburg will not provide any Network Vision coverage in Brownsville. You will have to wait until Brownsville starts deployment, though that could happen at the same time as in the other cities. AJ

    Ascertion, can you post some CDMA1X engineering screen caps? I am not certain that Rx diversity is active in idle state, only in traffic state. Thus, the secondary antenna stats might not be valid. I would like to see one screen cap with the handset idle, another screen cap with the handset on a traffic channel in the same location. Now, speaking of Rx diversity, here are a couple of Galaxy Note 2 jokes... That phone's so big, one Rx antenna is in New Jersey, the other is in Ohio. That phone's so big, one Rx antenna gets free night & weekend calling an hour before the other does. That phone's so big, when it switches from the primary to the secondary antenna, you get charged long distance. AJ

    How so? Dish's S-band/AWS-4 spectrum already was designated LTE band 23. AJ
  12. WiWavelength
    To be clear, CDMA1X most certainly does allow simultaneous connection to multiple PN offsets (i.e. soft/softer handoff), but that is through the use of a RAKE receiver, which requires only a single antenna and was part of cdmaOne from the beginning. My understanding of CDMA1X receive diversity is that it can be used to extend coverage and/or improve capacity. In CDMA1X, both coverage and capacity are limited by power. By using two Rx diversity antennas in the handset, a base station may be able to cover a greater distance at the same power level because when the handset's primary Rx antenna is in a fade, the secondary Rx antenna probably has a stronger signal path. Similarly, a base station may able to provide greater capacity by lowering its power level because, again, the two Rx diversity antennas help the handset cope with weaker signal strength. AJ
  13. WiWavelength
    I am fairly certain that with CDMA1X receive diversity, both Rx antennas are always tracking the same PN offset. I do not believe that they can track different sectors/sites. So, the latter -- antenna location -- is the more likely explanation. One Rx antenna has a stronger path to the serving sector. Furthermore, the primary and secondary Rx antennas often have different gain structures. So, one may naturally acquire a stronger signal than the other even if field strength is identical at both antennas. AJ

    No, it is not. Stop repeating this stupid analogy. Sprint's voice and data networks are effectively separate. Sprint has data network loading issues but generally does not have voice network loading issues. In other words, the voice network has plenty of capacity to spare. Moreover, a CDMA1X voice call requires an average throughput of approximately 10 kbps. That is minuscule compared to the average throughput of one data user on EV-DO or LTE. So, know what you are talking about before you speak. Do not equate unlimited CDMA1X voice with unlimited EV-DO or LTE data. They are not equivalent types of usage. AJ

    SID 06441 is definitely not Sprint. Sprint has no PCS 1900 MHz SIDs that high and few PCS 1900 MHz SIDs outside of the 04xxx range. So, if this is Tulsa, Cricket or VZW seems likely, since they are the other CDMA1X 1900 providers in the market. It is not USCC, which is CDMA1X 850 and has a much lower Cellular 850 MHz SID. Regardless, as Robert indicates, you could have been CDMA1X roaming yet with native Sprint eHRPD. AJ
  16. WiWavelength
    Those CDMA1X RSSI figures are relatively similar. But I doubt that the iPhone is using RSSI to drive the signal bars. Rather, it is probably using Ec/Io. And due to loading, Ec/Io can vary considerably with the same RSSI. AJ
  17. WiWavelength
    To be clear, EV-DO and eHRPD are the very same airlink. They differ only on the backend. Along those lines, EV-DO IP address ranges tend to be different from LTE/eHRPD IP address ranges. So, that may be one way to tell the difference on a handset that does not report eHRPD. AJ
  18. WiWavelength
    Has your closest Sprint site been upgraded to LTE yet? Or are you receiving an LTE signal from a more distant site? If your usual serving site already has been upgraded, then, no, nothing will change in the near future. LTE is a more fragile airlink than is EV-DO. Regardless, LTE and EV-DO at home should be irrelevant, as you should be offloading to Wi-Fi with a home broadband Internet connection. AJ

    Samsung Android 4.0 handsets can do a PRL swap by way of a simple home screen shortcut. The same may be true of Motorola handsets, though I do not know. AJ

    T-Mobile still offers its Classic plans, which include periodic device subsidies. But T-Mobile is really pushing its Value plans, which are cheaper, do not include periodic device subsidies, but allow subs to pay off their devices at $20 per month. That is the rationale behind the $499 Nexus 4 price at T-Mobile. Some people cannot afford $299 upfront at the Google Play store. Those people probably should probably save their money for more pressing needs, but T-Mobile will sell them the dream for only $19 down plus an extra $20 per month for two years. I give T-Mobile some credit for this, as wireless carriers need to stop being subsidized electronics retailers. If device subsidies were to go away, competition and affordability would force the so called $600 prices of these devices to drop. But distant third place T-Mobile acting alone is not going to enact such a sea change in the industry. So, Value plan subs just pay off the inflated prices of their devices over time. AJ

    If the hospital infrastructure is just a bidirectional amp and leaky coax, as I surmise, the coax is fine. Only the bidirectional amp might need to be replaced with a new one that supports the PCS G block. shifted, does the hospital have an arrangement specifically with Sprint? Or does the installed infrastructure benefit most/all carriers? AJ
  22. WiWavelength
    Oh, no, it is happening. Robert is already going T-Mobile prepaid. Pretty soon, he is going to start becoming "younger and edgier," wearing pink, and thinking that T-Mobile CTO Neville Ray is a "rock star." Dan, help us... AJ

    The EVO LTE is an enigma. Some days are better than others. For example, I have held LTE from Lawrence to Kansas City and Lawrence to Topeka, the EVO LTE handing off from sector to sector like a champ. Other days, I have driven the same routes with nary bit of LTE unless I manually intervene. AJ

    But not UNT. Maybe the Mean Green was mean to Sprint. AJ

    I am not surprised. Most store employees do not eat, drink, and breathe wireless the way that many of our members do. For most store employees, it is just a job, and one that they may not particularly like. But it is a means to a paycheck. AJ
