  1. Whoa, David is double fisting it on The Final Countdown. That guy is an S4GRUaholic. And I should know because I went to the Free State Brewing Company with him about a week ago. AJ
  2. No placeholder. "CLEARly, it's over" is already top notch. And I am a tough one to impress. AJ
  3. In the name of Banlandia, I stake claim to Day One of The Final Countdown... AJ

  7. It was faster than light speed. That is why you cannot see it. AJ
  8. Probably. As I recall the last two years, the preorder pages have gone online in the early afternoon. AJ
  9. Is the Google event still ongoing? When do the 2015 Nexus go up for order? Has that been revealed? AJ
  10. This, I do not get. I am hardly a Luddite, nor a cheapskate. In my house, I have tens of thousands of dollars of technology -- including no fewer than half a dozen laptop or desktop computers. None of them have greater than 4 GB of RAM, which should be enough. Software developers are getting fat and lazy -- why so much RAM usage? Pushing 3-4 GB on smartphones, are you kidding me? Or are you users running too many simultaneous apps? You do not have to do that. As the famous doctor joke goes, "Well, stop doing that." The Snapdragon 808 and 810 chipsets already incorporate Category 9 Snapdragon X10 basebands on die. Are you instead thinking of the the Snapdragon X12? AJ
  11. For flagship level devices, always check The Wall first. S4GRU is a non profit, non paid staff site. But we work hard for you. http://s4gru.com/index.php?/blog/1/entry-362-teaser-how-does-htc-m8-rf-performance-stack-up/ That said, in our FCC OET RF preview articles, we can present only lab tested figures, not real world performance. So, take with a grain of salt any numbers comparison between handsets nearly two years apart. AJ
  12. I…appreciate…your efforts. But were the raffle tickets kept inside...the "lockbox"? I would like…a recount. AJ
  13. I demand a recount. I believe these results to be…inockurate. AJ
  14. No, not really. You are moving the goalposts. Network Vision is providing an overall better network experience. Even the supposedly lowly 4 Mbps down, 1 Mbps up is highly usable and a better network experience. But that does not mean the same experience everywhere. That is not realistic for Sprint -- or for any other operator. Expecting the same experience everywhere is like expecting all the women to be strong, all the men to be good looking, and all the children to be above average. In wireless, the only consistency is inconsistency. AJ
  15. If you are still on SERO, do you have the right to complain about anything? Did Russ say that it was okay to whine? Or should you just thank your lucky stars that you are still getting such sweetheart/sham charity? As another S4GRU staffer and I discussed, SERO plan users with subsidy are on welfare -- subsidized by Sprint and the rest of us. AJ
  16. ericdabbs has a vested interest in maintaining contract subsidy. He is on a sweetheart/sham SERO plan that includes subsidized upgrades -- all of which is a problem in its own right. AJ
  17. Almost assuredly much sooner than that. The Google launch event is tomorrow, Tuesday 9/29. Ordering availability could go up this week. Delivery, though, is always a wild card with Nexus devices. AJ
  18. I am still under two year contract but have paid full price for several unsubsidized and/or unlocked handsets during that span. No big deal. Just get over it, and suck it up. And a $400 Nexus handset on subsidy would not be "on the cheap." The subsidy would more than make up for the cost of the handset. If it were priced at $200 or even $100 initial payment, that would add further insult to injury. Only a fool or someone with a cash flow problem would go for that deal. AJ
  19. No, you are completely misreading that report and its maps. Note all of the qualifiers -- namely, LTE and downlink. The former qualifier counts only spectrum that AllNet Labs deems present or possible for LTE deployment. That is speculative right there, especially as the article states that AllNet Labs subtracts 10 MHz of PCS from both VZW and AT&T holdings to account for legacy voice services. But what about T-Mobile and Sprint? Plus, the VZW and AT&T subtraction is largely arbitrary. The latter qualifier means that the spectrum depth is being expressed in FDD type format. So, in parts of northern Arizona -- not northern Phoenix -- Sprint may have 15-20 MHz FDD, which means up to 40 MHz of total spectrum just for LTE. And Sprint may actually have greater spectrum depth than that, since AllNet Labs is adjusting down any BRS/EBS spectrum holdings to account for TDD operation. In the end, I have found AllNet Labs work published at FierceWireless to be surprisingly amateurish, providing analysis that is no better than I can do and have done, not to mention, operating on a lot of assumptions. I will give AllNet Labs credit, though, for disclosing those assumptions in these published maps. But this exercise seems about on the level of fantasy football stat projections. In other words, not that reflective of reality. AJ
  20. Yes, but that is nothing new. It is exactly what I wrote in the article. AJ
  21. The Wall article: http://s4gru.com/index.php?/blog/1/entry-399-how-p-for-powerful-is-the-nexus-6p-rf/ AJ
  22. by Andrew J. Shepherd Sprint 4G Rollout Updates Monday, September 28, 2015 - 10:40 AM MDT Update: Now that Google has released the full tech specs for the Nexus 6P, we can write a few addenda. While the FCC OET authorization filings disclosed support for several GSM, W-CDMA, and LTE international bands -- something that they are not required to do -- they curiously omitted W-CDMA band 8, which is the GSM 900 MHz band. Add that one to the W-CDMA list. Additionally, we can confirm that the Nexus 6P will require a 4FF nano SIM. For Sprint activation, will it be a USIM or a CSIM? That remains to be seen. Stay tuned. Late last Friday afternoon, the LG manufactured Google Nexus 5X made its debut in the FCC OET (Office of Engineering and Technology) authorization database. S4GRU staffers quickly got down to work and broke the story with RF analysis that very evening. Following hot on the heels of its smaller sibling, the Huawei manufactured Google Nexus 6P made a bright and early morning FCC OET appearance today. S4GRU was on the case right away. So, let us dive right in to the RF nitty gritty. The Nexus 6P band support currently covers all major domestic operators -- VZW, AT&T, T-Mobile, Sprint, USCC, C Spire, etc. It even future proofs itself for AT&T usage to an extent by including nascent band 30 (WCS 2300 MHz), a band not present in the Nexus 5X. Moreover, it includes some notable international bands, which the authorization filing discloses. (Most FCC OET filings do not disclose international bands, as they are not required to be tested for US authorization.) For example, W-CDMA band 1 (IMT 1900+2100 MHz) is the primary W-CDMA band worldwide, and LTE band 3 (DCS 1800 MHz) is an emerging LTE band in many international markets. For your perusal, the many bands/classes... GSM 850/900/1800/1900 W-CDMA band 1/2/4/5 CDMA2000 band class 0/1/10 LTE band 2/3/4/5/7/12/13/17/25/26/29(Rx only)/30/41 From a physical standpoint, the Nexus 6P incorporates a dual antenna system. All LTE handsets that support 2x2 downlink MIMO must have at least two Rx antennas. But the Nexus 6P also utilizes a dynamic antenna capability on uplink Tx, switching between the two antennas at will, depending upon handset orientation and signal conditions. Interestingly, though, the dynamic antenna Tx capability is limited to low band spectrum. Only bands/classes below 1 GHz are supported. Lastly, in another twist, the Nexus 6P authorization filings did include an antenna diagram -- something that has become increasingly rare due to cited confidentiality concerns. On the other hand, the antenna gain figures were not apparent anywhere in the filing. For the diagram, see below: In keeping with most of this year's handsets based on the Snapdragon 808 or 810 -- both of which incorporate on die the Snapdragon X10 LTE modem -- the Nexus 6P supports 2x carrier aggregation on the downlink in both intra band and inter band configurations. In the case of inter band 2x CA, either band can be operated as the PCC (primary) or SCC (secondary). 2x CA downlink bands: 2-2 4-4 41-41 2-4 2-5 2-12 2-13 2-17 2-29 4-5 4-12 4-13 4-17 4-29 To wrap things up, let us examine the LTE band RF output. The usual provisos about lab testing versus real world performance and uplink versus downlink apply. The figures represent my best averaged and rounded estimates of maximum uplink ERP/EIRP test results provided to the FCC OET in the authorization filings for the device. Overall, the ERP/EIRP figures are fairly consistent within each band and across all bands. In terms of tested performance relative to other handsets, the measurements are roughly average. The P in Nexus 6P is not for RF "powerhouse," but it certainly could stand for "proficient." Compared to the Nexus 5X, the Nexus 6P has a 2-3 dB tested advantage in high band, while the Nexus 5X has a 2-3 dB lead across most of the mid and low band. ERP/EIRP: Band 2: 21-22 dBm Band 4: 21-23 dBm Band 5: 18-19 dBm Band 7: 21-23 dBm Band 12: 17-18 dBm Band 13: 17-18 dBm Band 17: 17-18 dBm Band 25: 21-22 dBm Band 26: 18-19 dBm Band 30: 20-21 dBm Band 41: 21-22 dBm Source: FCC
  23. You are starting to grate on me -- because now you are questioning our integrity, suggesting hypocrisy. Silence or acquiescence does not imply approval. Whitelisted and/or sponsored data is a transgression against the principles of Net Neutrality. No bones about it. That the FCC pussed out and failed to make it a violation -- maybe because John Legere would have thrown a hissy fit and played himself up as a victim -- does not make Music Freedom any more acceptable, any less wrong. Anyway, I will leave this here. It is from The Verge's deputy editor Chris Ziegler, who is far more influential and important than little old anonymous you, small web site tech editor me, or anybody else at S4GRU. AJ
