Verizon Communications Inc. Finally Launches a High-Voltage VoLTE Service

Verizon is about to give its voice services a huge quality boost: Video calling included, with no extra pressure on your data caps.

Aug 31, 2014 at 3:00PM

Verizon (NYSE:VZ) has been talking about a next-generation mobile voice system for years. Well, this is the end of the empty talk: Verizon is taking action.

Big Red will launch its voice over LTE service, or VoLTE, in "the coming weeks." This solution, which routes voice calls over Verizon's 4G LTE data network instead of its aging CDMA service, was first promised two years ago. The launch was delayed time and time again, allowing both T-Mobile US (NASDAQ:TMUS) and AT&T (NYSE:T)to launch their own VoLTE services in the meantime.

Verizon reportedly wanted to wait until it could offer VoLTE on a nationwide basis, and the LTE network appears to have met that standard now. Not all of Verizon's 4G smartphones will be able to support the new voice protocol, but the company has been selling compatible handsets for a while.

What's the big deal?
What's so great about VoLTE? 

First, these voice calls will be made in a significantly higher quality than traditional CDMA calls. This so-called HD Voice service uses a 60% richer audio standard, making for a much clearer representation of the human voice. Other carriers have been offering HD Voice services before Verizon, either on their legacy systems, or over VoLTE networks. This standard should eventually become compatible between one carrier and another; but for now, Verizon will simply enable HD Voice for calls made between two compatible Verizon phones.

Second, VoLTE adds support for video calls. You should be able to snap back and forth between audio-only and video conversations at any time, adding that personal touch to a regular phone call. Video calls are nothing new, and you may already be familiar with them from apps like Skype, FaceTime, and Hangouts. But this time, it's built into the standard voice calling system rather than managed by a third-party app.

This brings me to the third VoLTE benefit. If you're worried about this rich audio and high-bandwidth video using up your monthly data cap, Verizon promises to treat these calls the same as the regular voice calls from a billing point of view.  This means that they count against whatever monthly allotment of voice minutes you may have (often unlimited), and not against your data bandwidth limits. So these new and improved communications services won't dig into your restrictive mobile data caps. Neither FaceTime nor Skype can make that claim on Verizon's network.

Fourth, VoLTE is built on common Internet technologies. It's simply a special case of voice over Internet Protocol, or VoIP, communications. That opens the door to bigger and better things in the years ahead. Verizon refers to this bundle as "Advanced Calling 1.0," which is an indication of improvements to come. The data-based platform is scalable and open to modifications as new technologies and ideas come along.

The old CDMA network doesn't offer any of these advantages. And if that's not enough to get consumers excited about the new platform, consider that the CDMA-based networks still don't always allow you to access data networks while making a voice call after all these years. Getting around this limit would require activating separate antennas for the CDMA (voice) and LTE (data) networks, which is something popular models like Apple iPhones can't do. That restriction goes away when everything runs over the data connection to begin with.

Verizon has not yet shared exactly which handsets will be compatible with the new standard nor dropped any clues as to how long such phones have been sold. We're also in the dark as to the exact launch date. But the built-in VoIP service is finally coming, and chances are that a very large portion of Verizon smartphone users will be able to use it.

An early demonstration of the technology used an LG G2 handset that has been around since last summer. The popular Samsung Galaxy S3, S4, and S5 models support VoLTE services on other carriers. Apple (NASDAQ:AAPL) iPhones don't officially handle VoLTE quite yet, but its radio hardware reportedly knows how to deal with it, and the next iOS version is said to include software support for VoIP and VoLTE.

Verizon seems ready to open the floodgates on next-generation voice services. Big Red isn't first, and the update may not cover its entire smartphone footprint; but it's a huge step in the right direction. Soon enough, VoLTE will be the new normal in mobile communications -- and everyone will start looking for the next quantum leap.

And so it goes. For now, Verizon stays abreast with the state-of-the-art in wireless communications. And that's a good thing for the company, its users, and its investors alike.

Leaked: Apple's next smart device (warning, it may shock you)
Apple recently recruited a secret-development "dream team" to guarantee its newest smart device was kept hidden from the public for as long as possible. But the secret is out, and some early viewers are claiming its everyday impact could trump the iPod, iPhone, and the iPad. In fact, ABI Research predicts 485 million of this type of device will be sold per year. But one small company makes Apple's gadget possible. And its stock price has nearly unlimited room to run for early in-the-know investors. To be one of them, and see Apple's newest smart gizmo, just click here!

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

Feb 1, 2016 at 4:54PM

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.

Get the book. Listen to a podcast. Sign up for Investor Insights. I'm not saying that any of those things will make you rich ... but Business Insider seems to think so.
