    For as high-tech as our smartphones are, the voice calls they make decidedly aren't. Phones have long been held back by legacy voice standards, failing to take full advantage of the bandwidth and processing power of modern handsets. Luckily for us, salvation awaits in the form of voice over LTE, or VoLTE. Last month, Verizon shared its plans to activate its own VoLTE network in the weeks to come, and today we get word that it's getting things started, going live with what it's calling Advanced Calling 1.0. With Verizon VoLTE now active, how can you take advantage of it? Well, for the ...

    A couple weeks back, we were talking about the idea of smartphones that dropped all their 2G/3G radios in favor of going 4G-only, relying on LTE for everything from voice to data. While such an arrangement could offer some very real benefits, it sounded like we were still pretty far off, and hearing about Verizon's progress towards thatgoal, it was looking like we still might have another two years to wait. One of the stepping stones along the way, before losing the 2G/3G hardware, would be transitioning existing services over to LTE, and for years now we've been waiting to see voice ...

    When we're talking about smartphone radios, we're usually concerned with the latest-and-greatest tech they support – Cat 4 LTE, or even Cat 6 in some nations, for speeds reaching into the hundreds of megabits a second – so it's easy to forget just how much support there is for older systems, even those we rely on regularly. While there's some early progress towards things like voice over LTE, the vast majority of calls still get routed on older non-LTE networks. Even our data regularly dips into the 3G range, if not going all the way down to EDGE or even GPRS. Despite this reliance on ...

    Last week, AT&T shared news of its efforts to vastly improve voice call quality on smartphones, moving forward with its introduction of HD Voice, the carrier's Voice over LTE solution. We knew to expect HD Voice to go live this coming Friday in a number of Midwestern markets, and knew that the first AT&T phone to support the service would be the Samsung Galaxy S4 mini. Today we see AT&T's plans start coming together, as it begins sales of the GS4 mini. Wait a minute; AT&T didn't already have the GS4 mini? Yeah, we were a little confused as well, especially as we remember ...

    For all the advancements smartphones have made with high-speed data, audio fidelity, and advanced noise-cancellation, voice calls have been seriously stuck in the past. While our phones blast cellular data out at multiple megabits per second, voice has been constrained by its reliance on older standards – your $700 smartphone handles voice traffic in much the same way as a free-on-contract dumbphone. Progress has been slow to revamp voice, but the promise of voice over LTE – or VoLTE for short – has been looking like one of the most interesting options. This month, AT&T makes big ...

    The rise of LTE has brought alongside it a dream we've yet to see realized: that some day pure-LTE phones will be the norm, and we might finally get smartphones with radio support so broad that they could function on any carrier in the US. As things stand, we still have a long way to go, and all the currently-available LTE phones also have 3G and legacy voice support that can be carrier-dependent. Still, we've seen progress towards this goal, like the recent news of AT&T, Verizon, and T-Mobile trying a spectrum-sharing experiment. The latest development that has us hopeful comes from ...

    If you've never used a smartphone or tablet connected to an LTE network, you're really missing out. I've tested phones that get 35Mbps download speeds and half-that up at my home and at the office -- and I'm not particularly close to what anyone would call a "metropolitan area". Ironically, speeds like that are faster than my hardwired cable Internet connection that powers my home! Even "slow" LTE connections blow my HSPA+ speeds out of the water! All that speed comes at a cost: diminished battery life. Luckily, LTE doesn't have to be active all the time, just like other wireless data ...

    Yesterday, we talked a little about just how crucial battery life is to smartphones and tablets, and our desire to see manufacturers really buckle-down to offer models with some next-generation power savings. Unfortunately, tonight we have two tales for you of tech that's just not delivering the kind of battery performance we might like to see, with both the upcoming Windows 8 Pro Surface tablet and Voice over LTE technology coming up short. Microsoft came through with the Surface Pro pricing today, and while that was the big Surface news, an interesting tidbit also popped-up on Twitter. ...
