Yeah... but you don't want to be using a cell phone around those vapors! (Not that I'd know... the only meth labs I've ever seen were on "Breaking Bad"!)

Great explanation. Thanks for sharing. Perhaps Sprint's implementation will be upgraded in time? What "LTE Release Version" is Sprint operating on now for its Network Vision gear?

Sprint's new equipment as part of its Network Vision overhaul should readily accept a VoLTE upgrade AFAIK. I'm glad the other carriers are good competition, and they are pushing Sprint to be smart and nimble. Sprint is supposed to be done with its 800MHz LTE buildout by the end of 2015 in areas where rebanding is complete. I wouldn't expect VoLTE to appear until at least that's completed. Probably at least a year off so that the buildout can be further densified.

I'd be very surprised if Verizon developed an LTE Femtocell. Verizon's going to launch WiFi calling and say how great it is even though T-Mobile and Sprint have offered it for quite some time.... except in the case of iPhones which is recent for T-Mobile, and even more recent for Sprint. It'll also be interesting to see if Verizon decides to offer its own version of Sprint's WiFi Connect Router for free to qualified customers.

I take everything that Shammo says with a grain of salt... based on his comments in this article: However, he said Wi-Fi calling was "never a top priority" for Verizon. "We built our voice platform so extensively [that] there was never a need for us to tell our customers, 'Oh, our network is not good enough so you need to go on Wi-Fi to complete your call.'" Says the man whose company sells a Samsung Network Extender for $249.99. WiFi calling is free... so why would Verizon be in a rush for you to have that instead? (Of course, Verizon says WiFi calling is coming in Mid-2015.... I'll believe it when I see it.) Verizon claims its VoLTE coverage is good. According to other articles I've read, Verizon's LTE footprint is essentially its 3G footprint at this point.

Hopefully, Kevin Crull as Sprint's new Chief Marketing Officer (taking over on May 31, 2015) can better communicate these successes. See: http://newsroom.sprint.com/news-releases/sprint-names-kevin-crull-chief-marketing-officer.htm Sprint offers cutting edge technology at a great price. People should know about that... but they don't. The shame of it is that this page: http://www.sprint.com/netdotcom/index.html?ECID=vanity:network#!/ , which lists Sprint's technology, is essentially hidden as it's only accessible via http://newsroom.sprint.com/presskits/sprint-network-vision-information-center.htm, an out-of-date Press Kit from February 2015.... and... This Press Kit is only accessible if you go to http://newsroom.sprint.com/presskits.cfm and scroll down the list into the bowels of the archive. How useless. I swear, Sprint is its own worst enemy sometimes.

Stuff like this makes me sad. Considering how many government employees regularly use the Metro, isn't there a national security interest in having complete coverage? Of course, this is in addition to the general public interest. It's a bit alarming to be out of coverage and sitting in a dark tunnel.

Fantastic!

Did you go to "About" and update your carrier settings? See: Wi-Fi Calling FAQ's iOS Devices: Wi-Fi Calling is only available on iPhone 5c, 5s, 6, and 6 Plus models. It requires iOS version 8.3 and the Carrier Version 19.1 or higher. To update to iOS 8.3, go to Settings>General>Software Update. To update the Carrier Version go to Settings>General>About which will trigger the update. Complete this step after the 8.3 Upgrade.

Not sure if this counts as Network Vision, but it is market-specific.... And great news! http://newsroom.sprint.com/blogs/sprint-perspectives/play-ball.htm "On-air just in time for Opening Day on April 6, Sprint’s new Distributed Antenna System (DAS) will enable fans to better capture and share some of this year’s biggest moments in baseball. With a seating capacity of 37,903, Sprint – a longtime sponsor of the hometown Royals – is the only wireless carrier serving The K with a DAS. Sprint’s extensive system provides voice and data service throughout the entire stadium utilizing all three of Sprint’s spectrum bands (1.9GHz, 2.5GHz and 800MHz)." Any KC baseball fans here?

Oh? Where?

Who's Fabian?

Jeez. Is WiFi calling support for iOS still coming? What could be causing the delay? Sprint already supports WiFi calling on Android and it uses the same vendor (Taqua) as T-Mobile does for its WiFi calling feature.

Does anyone know the latest on WiFi Calling Support for iOS, and why it hasn't launched yet? Sprint's CFO made an announcement back on December 2, 2014 that it would launch in 60-90 days, but it's been radio silence since. What's going on?

I wonder if SoftBank is kicking in any capital or if those recent Notes issues ($1 Billion and $1.5 Billion) announced on Feb. 19th are paying for it.

You ought to let Marcelo Claure (@marceloclaure) know about this....

I think this is worth tweeting Marcelo Claure (@marceloclaure) about to let him know...

Yikes! Did you report the speed/coverage issues to Sprint Zone? You can also manually input the address.

Sprint's coverage maps now show that Washington DC has Spark coverage! Yay! (This DC market Spark launch was part of the Atlanta, Boston, Las Vegas, Nashville, Portland, San Francisco and San Jose markets Spark launch that Sprint's CNO John Saw mentioned would happen late-February.)

Did you report the Speed Issue in the Sprint Zone App? It's Washington, DC. See: http://www.bizjournals.com/kansascity/news/2015/02/18/sprint-lte-sprint-spark-network-expansion.html?page=all

Big news for Washington DC! See: http://www.droid-life.com/2015/02/16/sprint-is-launching-20-new-4g-lte-markets-on-february-19/ "On February 19, at least according to a Sprint’s recently updated list of 4G LTE markets, Sprint customers should see 4G LTE connections in 20+ new markets, including Washington DC, Vail, Colorado, and Maui, Hawaii." Also see: http://newsroom.sprint.com/blogs/sprint-perspectives/sprints-network-gets-back-in-the-game.htm "Later this month our coverage maps will show our faster 2.5GHz speeds in portions of places like Atlanta, Boston, Las Vegas, Nashville, Portland, San Francisco, San Jose, and Washington D.C. "

See: http://www.kansascity.com/news/business/article9624833.html From The Article: The shakeup at Sprint Corp. continues with apparent plans to update or change its familiar yellow logo. Word of a pending action came early Sunday in a wee-hours tweet (source: https://twitter.com/marceloclaure/status/564315007970594817) by chief executive Marcelo Claure. He responded to a question about whether Sprint is “ever going to” update to a new logo or color. Claure’s reply: “good question....soon..Stay tuned.”

:-) Would alien coverage be considered roaming? I use this to contact the mothership. Band 41 RF is fantastic!

Nice. :-) Wasn't sure if the University of Phoenix Super Bowl stadium would be a giant Faraday cage for Band 41 penetration.... Levi's Stadium is outdoors...

And the Band 41 from the COWS reached inside the Stadium?
