Do you mind checking which ServiceMode dial codes work on a Sprint variant? *#0011# *#2263# *#27663368378# *#197328640# Thanks a lot!

Yeah it looks like we have a confirmation that CDMA (at least Verizon) variant is equipped with Qualcomm MDM9635M: http://forum.xda-developers.com/verizon-galaxy-s6/general/verizon-samsung-galaxy-s6-32gb-hand-t3077381/post60014418#post60014418

Both AT&T and T-Mobile (and Canadian) variants are utilizing in-house Samsung's Shannon 333 modem all with full 3GPP support. AT&T also has it listed under tech specs: http://i.imgur.com/Cp40iCY.png Because of the lack of 3GPP2 support in Shannon 333, my educated guess that Sprint/Verizon baseband processor would be Qualcomm's MDM9635.

Dallas map excerpt from the slide shows coverage benefits achieved using L700 spectrum vs L2100 as of today. It doesn't mean that they're done with L700 overlay, but obviously L700 has greater propagation characteristics vs L2100, and it may not be necessary to overlay every single cell site in order to match and exceed the existing mid-band LTE footprint. I have no idea why would anyone begin to think that a Tier 1 wireless operator like T-Mobile would even consider removing their rural sites, knowing that the overwhelming majority of their subscriber base don't have L700 or VoLTE capable terminals. It would simply result in degradation of service and coverage gaps on GSM1900 and L2100 layers.

Another demonstration here:

Well it's been a year since the pCell original presentation, finally we're getting some activity. THE WHITEPAPER IS FINALLY HERE: http://www.rearden.com/artemis/An-Introduction-to-pCell-White-Paper-150224.pdf DISH will Lease Spectrum in San Francisco to Artemis for World’s First pCell Deployment Artemis I Hub Available for pCell Venue and Indoor Trials pCell compatible with off-the-shelf LTE devices such as iPhone 6, iPad Air 2 and Android devices San Francisco, CA – February 24, 2014 – Artemis Networks LLC today announced that DISH, through its wholly-owned subsidiary American H Block Wireless L.L.C., would lease certain H Block mobile spectrum in San Francisco to Artemis for up to two years for the world’s first deployment of pCellTM wireless technology, subject to FCC approval. pCell is a new approach to wireless that indoor testing has demonstrated delivering full-speed mobile data to every mobile device concurrently, regardless of how many users are sharing the same spectrum, thus achieving greater capacity than conventional LTE. Building on this testing, the first pCell service will be deployed in San Francisco subject to FCC approval. Rather than avoiding interference like conventional wireless technologies, pCell technology exploits interference, combining interfering radio waves to create an unshared personal cell (a “pCell”) for each LTE device, providing the full wireless capacity to each user at once, even at extremely high user density. To use the Artemis pCell service in the DISH-leased spectrum band, users will simply insert an Artemis SIM card into an LTE device, for example, an iPhone 6/6 Plus, iPad Air 2 or spectrum-compatible Android device. In the case of new universal SIMs that are just coming on the market, it’s even easier: users will simply choose Artemis as their LTE service on the screen. The device will then connect to Artemis pCell service as it would to any LTE service, but unlike cellular LTE service, Artemis expects that pCell will deliver consistently high speed throughout the coverage area, even in very high-density scenarios. If the user needs service outside of San Francisco, they will have the option of subscribing to roaming cellular service, which will be provided through an MVNO. Artemis also announced today the availability of the Artemis I Hub for venue and indoor trials. The Artemis I Hub provides pCell service through 32 distributed antennas, delivering up to 1.5 Gbps in shared spectrum to off-the-shelf LTE devices, with frequency agility from 600 MHz to 6 GHz, enabling pCell operation in any mobile band. Frequency-agile pWaveTM remote radio heads for outdoor use will be available later this year. Artemis Hubs and pWaves enable rapid deployment at a fraction of the installation and operating cost of conventional LTE infrastructure. Artemis Hubs and pWaves are also much simpler to deploy than conventional mobile infrastructure, opening the door for a wide range of partners to deploy Artemis infrastructure, starting initially throughout San Francisco. “We are delighted to introduce pCell to the world with the availability of the Artemis I Hub for trials,” said Steve Perlman, Artemis founder and CEO. “The Artemis I Hub enables partners to test pCell in indoor and venue scenarios using off-the-shelf LTE devices, such as iPhone 6/6 Plus, iPad Air 2 and Android devices.”

Yeah, that concept has recently been presented in Nokia's Carrier Aggregation White Paper.

And you're absolutely correct in that follow up post.

Well considering that Nokia literally just ran a public lab test of their FDD TDD CA solution, it's fair to assume that the commercial deployment will take a while. FDD TDD CA is defined in Release 12, and no commercial UE solution is available at the moment. My guess is that FDD TDD CA UE may be codified as Category 11/12, and we will see it at some point within 2016-17 timeframe. But as far as the actual aggregation, it definitely sounds like a standard supplemental downlink (1900MHz uplink + 1900/2500MHz downlink).

I just did. But if you carefully read that fiercewireless article from the OP, you'll also notice what T-Mobile stated: "Finally, T-Mobile said it "expanded backhaul capacity and put in place special event network parameters in and around the Glendale, AZ area to maintain T-Mobile's excellent 4G LTE coverage in this area."

Considering the lower amount of subscribers and their backhaul largely provisioned at 40Mbps per sector throughout the Phoenix market, all they really had to do is increase their backhaul provisioning and max out the air interface. That alone will probably do it.

I see... Thanks for sharing.

Can you give me an example?

What would you consider a screw up?

Charlie is looking to cash out on his spectrum position right about now, not sure if he's interested in spending more money on T-Mobile. That's probably his last choice right now. But if Marcelo decides to sell some of Sprint's 2.5GHz spectrum to let's say Verizon, Charlie's spectrum will instantly lose most of it's hype. In my opinion that's about the only scenario that would force Charlie to seriously evaluate acquiring or partnering with T-Mobile.

They've got crafty with their advertisement, guaranteeing absolutely no tangible improvement in user experience. They don't even mention that term once. They mention "optimal signal experience" http://www.att.com/network/en/index.html "AT&T’s network now has the nation’s strongest LTE signal 1. By doing things like placing LTE radios at the top of towers to maximize power and optimizing cell site density we've engineered our network to provide an optimal signal experience."

I'm not sure if anyone is challenging Verizon's overall quality of service, especially voice/text. But in this day and age of exponential growth in mobile data consumption, that data user experience is what operators have to constantly keep up with. If they're capable of providing a few mbps on average now, it doesn't mean they'll be able to provide the same in a year from now. This is why it's crucial for wireless operators to predict the pattern and preemptively invest into upgrades before the performance becomes abysmal.

Good! In Vegas Verizon only owns enough AWS for 10MHz FDD LTE. Even their PCS holdings are light, and they should be building macros or DAS/SmallCell at the very least.

Most definitely not.

They've been doing it since last summer. 700MHz LTE definitely helps, and VoLTE doesn't require massive amount of spectrum resources, so even the loaded Band 13 network is perfectly sufficient for VoLTE.

He is absolutely right. Verizon with sites spaced for CLR, and almost three times more subscribers than T-Mobile would either need to build more cell sites, or deploy more spectrum in order to keep up with the capacity demand. They happen to have large swaths of greenfield AWS which they've been deploying, but in markets like NYC they're obviously refarming PCS as well. Deploying spectrum is significantly cheaper than building new sites, so you can expect duopoly to ride that option until they can't anymore.

I'm in Queens, yeah we've had snow overnight, but to call this a "Blizzard of the century", followed by the decision to shut down all connections between the boroughs is beyond overhyped and unnecessary. We've had much, much worse storms. And I've had a feeling right from the get go that this is gonna be the case, so we skipped the usual cash dumping at the local grocery store. Were we lucky? Probably. But the media and local government jumped the gun, and most likely lost a lot of trust out of the average New Yorker.

Uh oh... http://www.cnbc.com/id/102371281 "Meteorologists apologize for huge blizzard miss"

Meh... I'm used to it. Don't even go for massive shopping sprees anymore. Hey, but I appreciate your work man.

Heh.. I've been through quite a few "blizzards" here in NYC. All of them overhyped. The reason? To get as many people to spend as much money on food and other supply. "Let's boost the economy!" This has been by far the weakest of them all, but the most hyped. They've managed to shut down the entire freaking island of Manhattan... For what?!
