  1. Yeah, "naked browsers" are great. AJ
  2. Some things thou shalt not do. Father Apple only wants what is best for you, knows what is best for you. Listen, follow, and your reward will come when you go to that big orchard in the sky. AJ
  3. Josh, meshuganeh, how can you do that to Saul? You act as if you have never heard of him, yet you expect Saul to sit around on the weekends just waiting to run your debit card? http://www.youtube.com/watch?v=Zg6_9z0Rpuk Oy vey... AJ
  4. ...which furthers my commandment: THOU SHALT NOT ASK ENTRY LEVEL WORKERS TECH QUESTIONS. AJ
  5. I highly doubt that you had "good 4G signal." Did you actually check your LTE signal strength? Inside Arrowhead on the field level, LTE signal strength is weak (-115 dBm RSRP) in the stands to nonexistent on the concourse. The one caveat is that signal strength might be better on the view level. Regardless, the Kauffman Stadium site does not have active LTE yet, so any LTE signal at the sports complex right now is just spillover from sites in the surrounding area. AJ
  6. ...because punctuation creates emphasis. From the annals of "Seinfeld:" AJ
  7. The Upper 700 MHz C block 22 MHz licenses -- which is the only spectrum that VZW currently uses to provide LTE service -- have "open access" requirements that were triggered by exceeding predetermined reserve prices. The Lower 700 MHz A block 12 MHz and B block 12 MHz licenses in question here have no such requirements. AJ
  8. It must be because your debit card issuer -- Saul's Dry Cleaning, Savings & Loan -- is closed on the weekends. AJ
  9. Geez, what the hell do you expect? You were almost certainly talking to a phone drone, an entry level worker who knows next to nothing. I am ceaselessly amazed that people think that a call center worker has engineering knowledge or executive power. AJ
  10. Do you have any idea with whom you are speaking? I am a Justified Ancient of Mu Mu. AJ
  11. No, more likely, Dame Edna... AJ
  12. True. The Note 2 AMOLED subpixel structure finally ditches the PenTile arrangement in the Galaxy S3, etc. But AMOLED still has problems. It is woefully inaccurate, cartoonish eye candy with burn in issues. Have you ever noticed that no laptops come with AMOLED screens? I am not sure that AMOLED is any more appropriate for mobile phone screens at this time. http://www.anandtech.com/show/6386/samsung-galaxy-note-2-review-t-mobile-/8 AJ
  13. I don't know how to say this, but are you "kind of a big deal"? AJ
  14. Does that speak to the size of the phone or the size of the head? AJ
  15. Before the end of the year, I am going to publish on my blog -- which I have sadly neglected since the summer -- a piece on Cellular 850 MHz band reform. As the Cellular 850 MHz band plan stands now, parts of the band (fully 10 MHz out of 50 MHz total) are convoluted and cannot feasibly be used for anything other than AMPS or GSM -- not CDMA1X and only maybe LTE, even if so, just the meager 1.4 MHz FDD configuration. That is not a big problem in the near term as 2G, 3G, and 4G all intermingle in Cellular 850 MHz, but it will become a decided waste of valuable spectrum by 2020 as carriers move exclusively to LTE. Even realigning the Cellular 850 MHz band plan to create two wholly contiguous 12.5 MHz x 12.5 MHz licenses would not fix the problem, since LTE has standardized 10 MHz FDD and 15 MHz FDD configurations, but no 12.5 MHz FDD configuration. So, that would still leave the same amount of spectrum (10 MHz) on the margins underutilized. To address this issue, I am going to advocate that the FCC rejigger the Cellular 850 MHz band, taking the current Cellular A block and B block licenses and creating an additional C block license from the underutilized spectrum. Cellular A block and B block licenses would be 10 MHz x 10 MHz, C block license 5 MHz x 5 MHz. AT&T and VZW, of course, would oppose such a Cellular 850 MHz reconfiguration, since they would rather use spectrum inefficiently than open the door to a third competitor. But Cellular 850 MHz spectrum was not auctioned; it was awarded in a "beauty contest" fashion in the 1980s. Since then, many carriers have become incredibly wealthy just by holding, buying, and selling Cellular 850 MHz spectrum. That is unjust enrichment by way of a public resource. So, it will be high time that the FCC use its authority over public spectrum that many licensees got for free. The upshot for Sprint is that a third Cellular 850 MHz license could be made available in the coming years. Moreover, if the hypothetical Cellular C block license were positioned at the low end of the Cellular 850 MHz band, it would be directly adjacent to and contiguous with Sprint's rebanded ESMR 800 MHz holdings. Mull that over... AJ
  16. Note 2 users, you are being watched (gawked at). Posted in another forum: AJ
  17. Two thoughts... 1. If you are not receiving incoming calls at a specific location, then you could be near a NID boundary. Sprint will not, cannot fix that network characteristic. The best that you can do is install an Airave at that location. 2. If you are dropping calls, maybe most of your callers are AT&T subs, and they are the ones who are actually dropping the calls. Or people could be just hanging up on you (I kid, I kid). AJ
  18. Ah, look at those "happy little trees." AJ
  19. No. Do not encourage unauthorized tethering. That is a violation of the Ts and Cs, not to mention, unethical. Unlimited data is *limited* to a single device. That restriction is part of the price you pay for unlimited data. AJ
  20. There shall be LTE in Cincinnati when Mike Brown becomes a good NFL owner. So let it be written; so let it be done... AJ
  21. Sprint iPad 4/iPad mini RF article is up on The Wall. http://s4gru.com/index.php?/blog/1/entry-333-sur-la-tablet-apple-ipad-4-ipad-mini-add-sprint-lte-support/ AJ
  22. by Andrew J. Shepherd Sprint 4G Rollout Updates Wednesday, October 24, 2012 - 12:05 PM MDT Over the past six months, Apple's iPad 3 has racked up millions of sales, yet Google's (and Asus') Nexus 7 and Microsoft's Surface tablets have grabbed the headlines over the summer and into the fall. Yesterday, Apple struck back by not only rolling out iPad 4 the same year as iPad 3 but also introducing the long rumored iPad mini. S4GRU readers will recall that Sprint was left out of the iPad 3 sweepstakes, Sprint's nascent LTE network making its debut a few months after iPad 3's announcement. Certainly, some will bemoan that iPad 3 has been replaced in only half the usual yearly upgrade cycle, but Sprint users definitely benefit, as Sprint is fully in the fold this time with LTE support on the VZW/Sprint/global versions of both iPad 4 (A1960) and iPad mini (A1955). As soon as Apple's announcement event concluded yesterday, authorization filings for the new Sprint compatible iPads (iPad 4, iPad mini) started popping up in the FCC OET (Office of Engineering and Technology) database. So, joining our series of articles on on the HTC EVO 4G LTE, Samsung Galaxy S3, Motorola Photon Q 4G, and soon to be released LG Eclipse and Samsung Galaxy Note 2 is an RF capability focused look at Sprint's first two iPads: CDMA1X/EV-DO band classes 0, 1, 10 (i.e. CDMA1X/EV-DO 850/1900/800) EV-DO Rev B Multi Carrier (i.e. 2xEV-DO, 3xEV-DO) LTE bands 1, 3, 5, 13, 25 (i.e. LTE 2100+1900/1800/850/750/1900) LTE 1900 1.4/3/5/10/15/20 MHz FDD carrier bandwidths W-CDMA bands 1, 2, 5, 8 (i.e. W-CDMA 2100+1900/1900/850/900) DC-HSPA+ (i.e. Dual Carrier) GSM/GPRS/EDGE 850/900/1800/1900 802.11a/b/g/n Wi-Fi Wi-Fi hotspot (2.4 GHz only) support for all cellular airlinks Maximum RF ERP/EIRP (iPad 4): 23.10 dBm (CDMA1X 850), 22.90 dBm (EV-DO 850), 30.12 dBm (CDMA1X 1900), 29.08 dBm (EV-DO 1900), 23.30 dBm (CDMA1X 800), 23.40 dBm (EV-DO 800), 29.78 dBm (LTE 1900) Antenna gain (iPad 4): -1.58 dBi (Cellular 850 MHz), 2.44 dBi (PCS 1900 MHz), -2.24 dBi (SMR 800 MHz) Antenna locations (iPad 4): (see FCC OET diagram below) The inclusion of EV-DO Rev B Multi Carrier and the imposed limitations -- Cellular 850 MHz only, no 64-QAM -- are a bit curious. But these limitations will have no ramifications for use in North America, where EV-DO Rev B has not been deployed. All told, though, both iPad 4 and iPad mini look to be solid RF performers. Not surprisingly, since they share the same Qualcomm MDM9615 modem with iPhone 5, both iPads carry over basically the same airlink capabilities from the Sprint compatible iPhone 5 -- see S4GRU writer Ian Littman's article. And it should be noted that iPad mini, despite its diminutive size, does not lag behind its larger sibling. All ERP/EIRP figures are within ~1 dB between both iPads. In fact, for both EV-DO 1900 and LTE 1900 maximum EIRP, iPad mini trumps iPad 4 by ~0.5 dB. Furthermore, both iPads in their high ERP/EIRP outputs are less like power and size constrained handsets, more like mobile hotspots. Indeed, both iPads appear to be very capable hotspot devices.

  23. Not just one. O'Keeffe painted many -- especially if you are prone to imagination. Robert, avert your gaze. AJ
  24. The "Apple tax" for all iPad/mini LTE variants is effectively $130. I am interested and have ample disposable income, but I question that the Qualcomm MDM9615 -- a good modem -- is worth that premium. AJ
