  1. Verizon seems like they really want to get out of the wired lines business. Maybe they ought to consider buying Dish and setting their wired division to Centurylink or some other company that wants to be in that business. That way they can still leverage their satellite business to offer content.

     

    If I were Sprint, I might try the opposite tack. Staying out of the content game and being a wireless provider and Tier 1 ISP. Much like they are doing with their RRPP, maybe they expand their fiber network and provide backhaul for many CLECs?

  2. Anyone think we will get a second update for Stagefright? According to the Stagefright Detector app from Zimperium, the patch fixed 5 of the CVE-2015 Stagefright related vulnerabilities (3828, 3824, 3829, 3827, and 1538). However, CVE-2015-3864 still seems to be affecting the M8.

  3. Thanks for explaining, adds to my armchair wireless "cred". Is TDD affected the same way,, with the shared channels? I apologize if it's been discussed prior...

    With TDD you can set different ratios for uplink and downlink. The catch is they can't vary from site to site, or they would step all over each other.

  4. No, it is capable of 3x CA.  Cletus is more or less correct in the post above.

     

    The Snapdragon 810 and 808 are no different in baseband abilities.  Both have on chipset the same Snapdragon X10 LTE modem.  The AnandTech article is a bit out of date now, as the Snapdragon X10 LTE is not an MDM9635 integrated on die.  It has been improved to a Category 9 modem, and no standalone MDM96xx baseband exists with the same capabilities.

     

    Back to 3x CA, though, that also requires multiple RF transceivers or a next generation RF transceiver.  No Sprint device, to our knowledge, has implemented 3x CA -- even though the latest Qualcomm modems support 3x CA on Sprint.  Basically, wait for the next round of flagship caliber handsets for 3x CA 20 MHz TDD band 41.

    Frankly, improvements in reception are more important to me than support for aggregating more than 2 carriers. At least on mobile devices. I could see wanting 3xCA on built into a netbook or laptop though.

  5. 4k for phones is patently absurd.  The only reason for that kind of resolution on such a small screen is for VR purposes or if you're playing off that device to a larger screen.

     

    As others have mentioned above, compression is a much greater factor in perceived quality at that screen size.

     

    I work with 5k and 6k footage on a daily basis and that's for post/VFX reasons.  I'm definitely not against higher resolutions, it's just a waste of bandwidth where not needed.

    Exactly! When creating content, you ideally start with a higher quality/resolution source than you will use for final distribution. Just because you have a 4k (or 6k, 8k) source material, doesn't mean it needs to be distributed in that form for consumption. Frankly most people can't tell the difference between 720 and 1080p on their biggish screen TVs because they sit too far away from them. Now that's not true on larger screens when people sit closer, but on a 37 or 42 in TV, when people are sitting 6-8 feet away...

  6. Any quality improvement from 720p to 1080p on a 5 in screen is more likely related to compression than resolution.  Streaming services seem to "bit starve" the lower resolution options more than they do the higher resolution options.  In a blind test, play a clip at 720p with an adequate bit rate, then the same clip at 1080p, and you would be hard pressed to tell the difference.

     

    The same holds true for most HDTVs.  At typical viewing distances, people cannot tell the difference between 720p and 1080p.  The upgrade from 1080p to 2160p is not going to change that situation -- especially not on just a 55-60 in display, unless it is being used at a computer monitor viewing distance.  No, almost any visible improvement from UHD will come not from 2160p but from wider color gamut, additional frame rates, and more meticulously captured or scanned source material.

    I like to think it's more helpful to think about it in terms of DPI and distance from the screen. A 50 inch TV and a phone with a 5 inch screen might both be "1080p" but the DPI on the phone screen is ten times higher because you are jamming those pixels into a screen one tenth the size. Now you are usually much closer to the mobile screen too, but frankly, unless you are sitting at distances more typical of a computer monitor, I think 2k and 4k displays are kind of a waste as TVs go. 

  7. Support is a bunch of people sitting in front of a computer terminal with very little techincal and no engineering background.  There is nothing they can do or tell you that the computer doesn't already say.  They aren't getting the true details other than on/off.  You can turn on the notification data gathering setting in your Sprint Zone.  At least that will send back some technical data to Sprint that they will hopefully analyze.

     

    Where do you go in the Sprint Zone app to turn this on?

  8. I was playing with whitelist function on the Sprint.com website and bricked my AIRRAVE.... should of left it alone...Manage my AIRRAVE on Sprint.com is broken.

    The tech I was on the phone said, however, that as soon as all the non-Wi-Fi calling phones are upgraded they will deprecate all the Airraves....guess that Wi-Fi calling will be the way they are going.

    I'd guess that it's cheaper for them to deploy one of these routers than an airrave.
