Sprint's HD Solution
Late last year, Sprint demonstrated what it hoped would be its own competitive differentiator -- technology that delivers 1 gigabit per second (Gbps) over-the-air speed and has the potential to surpass wireless speeds of any U.S. network provider -- at least for now.
Dubbed Sprint Spark, the super-high-speed capability demonstrates 50 megabits to 60 megabits per second peak speeds today with increasing speed potential over time. Given Sprint’s spectrum and technology assets, the company said it is technically feasible to deliver more than 2Gbps per second of over-the-air speed. The service started rolling out in March in 100 of America’s largest cities.
“Sprint Spark will also offer high definition voice. This is supposedly a much higher quality voice call than traditional wireless,” Kagan said. “So could Sprint actually break out their old advertising from the early 1990s with the pin drop to illustrate the excellent quality? True, that was for wireline and this is now for wireless, but they can update it, can’t they?”
This article was corrected to reflect that AT&T is the first deploying a VoLTE network to provide high definition voice service -- but not the first to offer HD Voice in general.

HD voice is not a "strategic differentator" because everyone will have it by the end of the year in some flavor. Seriously?

Tmobile has already deployed VoLTE in Seattle

AT&T is not the first to launch VoLTE because they have not launched it yet. Zero customers are using it, because no handsets are available. And regarding HD Voice, T-Mobile has already had that nationwide for over a year.

@TakagawaU16: Thanks for that correction. We have updated the article to fix.

Not 3.4Hz, but 3.4KHz.
Not 7Hz, but 7KHz

@EMZ: Thanks for pointing that out. We have updated the article to clarify.

Completely wrong. Sprint launched HD Voice service two years ago, and T-Mobile launched HD Voice service in 2013 on the iPhone. Both smaller carriers offer it, albeit in limited markets.
AT&T is, however, the first to deploy VoLTE.
