  1. The FCC does not do the testing. The manufacturers or their contracted labs do the RF testing. If HTC thought the results were in error, it would not submit them to the FCC. AJ
  2. The article is on The Wall: http://s4gru.com/index.php?/blog/1/entry-400-htc-one-a9-the-first-sprint-handset-to-support-uplink-2x-ca/ AJ
  3. Brief history on HowardForums? It would not be that brief. AJ
  4. Take the $60,000 out of John Legere's corporate wardrobe allowance. He has to scale back to weathered jeans and pink T-shirts from now on. Wait, he already does that. AJ
  5. I am unsure what you are posting, but this appears to be some sort of log output. You have two 20 MHz TDD band 41 carriers: the first centered at 2513.6 MHz as EARFCN 39826 and a second centered at 2533.4 MHz as EARFCN 40024. Both of those are known. The first already is in the list in the top post. The second previously has been reported, though I have not gotten around to updating and adding it to the list. AJ
  6. The View New Content button is your friend. Threads with new posts rise to the top. AJ
  7. Nope. The superscript "2" indicates a second carrier in that band. It has no explicit relevance to carrier aggregation. AJ
  8. Which T-Mobile troll is this? And was there an incident at FierceWireless that prompted a move to HowardForums? AJ
  9. If exclusively so, then there will be no Sprint variant Samsung Galaxy S7. Sprint will be left out. VZW, AT&T, and T-Mobile will get their variant(s) -- with VZW voice service VoLTE only, as in the HTC One A9. AJ
  10. If on Family Match, all lines must have the same data allotments. AJ
  11. Yes, you need to configure at the Gmail site first. Under Settings > Accounts and Import > Send mail as. I have four different e-mail addresses configured, including my s4gru.com domain tech editor address. I can use Gmail to send from any of those four addresses. Once configured via browser, those Send mail as options are available via mobile app, too. AJ
  12. For replies, you should be able to set up Gmail to send as your Hotmail address, too. AJ
  13. Can you set up automated forwarding from Hotmail to Gmail? AJ
  14. My philosophy on firmware updates is "If it ain't broke, don't fix it." But in Robert's case, uh, it's broke. AJ
  15. Here would be an interesting litmus test. I wonder how Music Freedom would fare against an Americans with Disabilities Act court challenge. A deaf person has all data usage counted against a quota, yet a hearing person has some audio data usage zero rated. That is arguably both anti accommodation and discrimination. http://www.theatlantic.com/technology/archive/2015/04/does-the-ada-apply-to-online-spaces-too/390654/ AJ
  16. by Andrew J. Shepherd Sprint 4G Rollout Updates Thursday, November 12, 2015 - 3:07 PM MST Yes, you read that correctly. Thanks to the mid range Qualcomm Snapdragon 617 (MSM8952), the HTC One A9 is the first Sprint handset to include a modem that supports uplink 2x CA (carrier aggregation). That comes on die via the X8 LTE modem, which is a Category 7 LTE baseband, capable of aggregating up to 40 MHz FDD/TDD 2x CA on both the uplink and downlink. Now, before anyone gets too excited, Sprint has no imminent plans to enable uplink 2x CA at the network level. So, the uplink 2x CA support is mostly a proof of concept novelty. If you have been reading The Wall at S4GRU for a while, you probably know where this is headed. It is another in our classic series of FCC OET (Office of Engineering and Technology) RF authorization analysis articles. We do not dwell on processor benchmarks, screen qualities, etc. If you want that info, read reviews or visit the HTC tech specs site. Instead, we cut right to the heart of what a cellphone is -- a cellular RF device -- and rundown its lab tested cellular RF performance. The One A9 filed its FCC OET authorizations over a month ago, but with Sprint selling the handset as we speak and HTC shipping the unlocked Sprint variant next week, we should take a look. Let us start with the band/class support: CDMA2000 Band Class 0/1/10 GSM 850/900/1800/1900 W-CDMA Band 1/2/4/5 LTE Band 2/4/5/12/25/26/41 The Sprint and CCA/RRPP band support is expected at this point. But all of the GSM/W-CDMA band support info comes directly from the HTC tech specs. I state that explicitly because there is no testing of domestic GSM/W-CDMA in the FCC OET documents. Barring a Class II Permissive Change filing with the FCC, the GSM/W-CDMA support purely is for international roaming. While the Sprint variant One A9 can be unlocked or even purchased unlocked, it is not authorized for use on AT&T or T-Mobile -- unless you can live with no GSM/W-CDMA, only band 2/4/5/12 LTE. For an unlocked One A9, HTC proactively has addressed the to/from Sprint provider switch issue by including that in its one time courtesy UH OH Protection program: In other words, want to switch from Sprint to AT&T, T-Mobile, or VZW with your unlocked One A9? HTC will swap out for the other domestic variant. Want to switch from AT&T, T-Mobile, or VZW to Sprint with your unlocked One A9? HTC will swap out for the Sprint variant. While on the subject of the AT&T, T-Mobile, and VZW variant, it is 3GPP only, thus VoLTE only for voice on VZW. HTC even acknowledges that fact: The other domestic variant has some further relevance as we delve into the FCC authorized lab tested ERP/EIRP performance of the Sprint variant. The FCC OET documents, per usual, do not disclose an antenna diagram. But they do note that the One A9 uses a dual antenna system -- antenna 0 and antenna 1, presumably top and bottom or vice versa. The handset will switch between the antennas at will based upon varying signal metrics. Much like Apple with the iPhone, HTC has implemented this dual antenna setup since the debut of the One M7 in 2013. In this case, however, the dual antennas are still single radio path, so SVLTE is not supported. Now, for the main attraction, let us look at the Sprint variant One A9 radiated power figures. I may sound like a broken record, but the usual clauses about lab testing versus real world performance and uplink versus downlink always 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. See below: Band Class 0: 17 dBm Band Class 1: 22 dBm Band Class 10: 18 dBm Band 2: 16-19 dBm Band 4: 13-16 dBm Band 5: 14-16 dBm Band 12: 14 dBm Band 25: 17-19 dBm Band 26: 16-17 dBm Band 41: 21-22 dBm The CDMA2000 performance is good, about average. And the band 41 output is along the same lines. That is about the best S4GRU can say regarding the tested results of the One A9. It does not quite hit the lows of the VZW variant Samsung Galaxy Note 3 -- the most anemic RF test results that S4GRU has ever seen in any notable handset -- but the One A9 is not far off. The band 4 output that maxes out as low as 13 dBm, for example, is very weak. It is mid band spectrum that needs greater EIRP. The positive is that band 4 roaming never may be a factor with this handset. And band 2/25 is a bit better, though still at least 4-5 dB below the desired level. Now, back to the other domestic variant headed to AT&T, T-Mobile, and VZW. The picture does not get much rosier. Comparing the 3GPP bands in common, the other domestic variant is superior by 2-7 dB in band 2, 6-9 dB in band 4, 2-4 dB in band 5, and 2 dB in band 12. Wow, those are big differences nearly across the board. The Sprint variant does get one minor victory -- it is 1-2 dB better in band 41 than the other domestic variant is in band 7, as both band 41 and band 7 operate in the same BRS/EBS 2600 MHz spectrum. What happened, HTC? The Sprint variant seems to have gotten shortchanged. Was that a compromise to optimize band 41 by 1-2 dB? We can hope for better returns in real world performance. But early returns from lab tested performance are not good. Sources: FCC, HTC, Qualcomm
  17. I did not see this posted yesterday. "Unlimited" data plan price also is increasing from $80/mo to $95/mo. And, of course, that is non contract without any device upgrade subsidy. Many have not wanted to hear it, but several of us at S4GRU have been saying this for years. "Unlimited" data for the masses is not tenable and will become more and more expensive. http://money.cnn.com/2015/11/11/technology/tmobile-unlimited-plans/index.html AJ
  18. "Hey, hey, hey! You gotta do it! Do what you want!" Robert, you're disenfranchising me. Don't interrupt me while I'm dancing to the music, looking at the pretty colors, and hearing what I want to hear. AJ
  19. Nope. What you propose just is not feasible, not for startups yet to make it big or that now may never make it big, nor for individuals who have their own servers. richy, you and I usually agree on issues. But I am disappointed with you on this one. You are dead wrong. This is data discrimination -- bar none. And it is not done with any justification of network management or federal regulation. Zero rating is playing favorites -- positive discrimination -- which is still discrimination, still anti Net Neutrality. Just because you or some people "like" it does not make it less prejudicial and discriminatory. Let "Seinfeld" ironically tell the tale... AJ
  20. Both the Snapdragon 808 and 810 already supported 3x CA aggregated 60 MHz FDD/TDD. The Snapdragon X10 LTE baseband was not the limiting factor. However, 2x CA used only one RF transceiver, while 3x CA required a second RF transceiver. Unless that requirement has changed, then the Snapdragon 820 with Snapdragon X12 LTE baseband is little different from its predecessors on the 3x CA front. So, do not get overly excited. AJ
  21. You can print the full headline from The Verge -- just not the full article. Even though it normally would fall outside the S4GRU posting guidelines, the headline itself is newsworthy.

  22. On a 5-6 in screen, video resolution is not the issue -- 1080P, 2K, and 4K are a waste. People confuse resolution with quality. But for video at those screen sizes, compression and bit rate are the quality issues, not resolution. AJ
  23. That is what multicultural Millenials do all day -- jump and bebop around in their skinny jeans. AJ
  24. The Snapdragon 820 was announced months ago. So, this is just an official debut. We will need to adjust the thread title. AJ
