While there are advancements in almost every aspect of smartphones on a nearly daily basis, there is one area in which phones have seemingly been the same for years: voice calls. More specifically, call quality. Sure, we have nifty tools like VoIP and the like, but, overall, the quality of conversation whilst talking on a mobile network could use some oomph.

That's exactly what Fraunhofer IIS, looks to bring to the table at Mobile World Congress next week. This advancement in voice calls allows for full-HD quality, will run completely in a VoLTE (voice-over-LTE) environment, and sounds absolutely incredible. It sounds as if you're in the same room with the person with whom you're speaking. To get a better idea of how good it actually sounds, check out Fraunhofer IIS' demo right here.

There's no word on when we could start seeing this technology implemented into smartphones, but it will definitely be a nice enhancement when that day arrives.

    I often have trouble understanding people on my phone, so this is fantastic!

  • Juggalotusheat

    Hopefully they will integrate this in a way that allows for older infrastructure to be used when there is no data or when verizons LTE drops data, which it does often.

      Ahh just look at those data caps. Hope you did not think that this would not count towards your data.

  • Tony

    The only people I struggled to understand on any of my Android phones, is people with any kind of iPhone. They always sound muffled and terrible.

  • caleb

    What is this going do to the battery life?

  • Alex

    In regards to battery life, I would assume it would improve it since mobile devices would no longer be required to have two radios (one for voice and one for data).

    • J-Dog

      For the foreseeable future I don't see phones being shipped without both a voice & data radio, even with this technology in place. Not everywhere has LTE service yet - my home town doesn't even have 3G service (on AT&T at least, and Verizon's 3G coverage is qusi-spotty). Considering ~15k is the largest city in the area, I doubt we're on anyone's short list for getting 4G anytime soon. So a phone with just VoLTE abilities would be useless here.

      Also, as Juggalotusheat points out, Verizon's LTE network hasn't had the best track record - going down at least once every other week or so lately. If the phone doesn't have a backup voice radio, again, useless.

      Also... LTE radios are battery hogs. My old, voice only, LG VX4500 use to be able to last the better part of a week between recharges. From what I've been hearing, people with 4G phones are lucky if they make a full day out of a single charge. VoLTE would require heavier use of the LTE radio, thus draining the phone even faster... So while you might save some juice by using only 1 radio, until we can figure out how to make LTE radios more power efficient, I'd assume you'll end up using more than you save.

    My understanding was LTE WAS the future of voice calls, according to the president of Verizon. Which of course makes sense, and the data caps won't matter.

    Imagine how much battery life the phone will have if it isn't dealing with different radios.... :)

  • Blake

    This will be great! Then Verizon's dropped call rate will skyrocket because they can't seem to keep LTE connected. My LTE drops so much that i've completely turned it off on my GN. EVERY day driving home it drops, 100% of the time. Makes me question why I pay for Spotify as well at times...

    Finally!!! We have HDTV, HDRadio, but all phones, especially cell phones, sound like crap!
