Verizon interview: Our true 5G network will offer a better experience than rivals


One of many largest subjects on the 2019 CES is 5G — particularly, what 5G networks and units will appear to be as they start to turn into out there all through the world. Verizon was the primary main service to launch a business 5G network and is at present serving clients in 4 U.S. cities with a 1Gbps wi-fi answer. Over the subsequent few months, its network will each broaden and add help for cellular 5G units, competing with AT&T’s extra just lately launched however seemingly nonetheless nascent 5G network.

As CES 2019 kicked off, I had the chance to interview Verizon VP of Network Engineering Mike Haberman, who offered useful insights into the distinctive means Verizon is approaching 5G, in addition to how its network will evolve all through 2019. Briefly, Haberman — an engineer chargeable for the network buildout — says that Verizon is taking the thought of “true 5G” critically, implementing the 5G normal’s highest-performance parts to offer a totally different and better buyer experience than its rivals.

Right here’s a frivolously edited transcript of our dialogue.

VentureBeat: How will the transition work from Verizon’s present 5G TF residence broadband network to its 2019 5G NR cellular network?

Mike Haberman: We launched what we name 5G House in 2018, and that’s a actual system with actual clients. That’s actual 5G, utilizing TF commonplace, know-how type normal. Clearly, what occurred is that TF was a bunch of the larger infrastructure distributors and us main the best way, and we drove the business to get 5G out, and what ended up occurring was that the 5G NR commonplace was accelerated. Which was nice from our standpoint. From a network perspective, all of the elements are the identical.

It’s merely simply upgrading that final leg, which will occur, and we’ll do this when it’s prepared without charge. It’s simply a modem improve on the home, and it’s designed to be upgraded, and a few of the gear might be upgraded with software program. It’s all millimeter wave (mmWave), so it has the identical radio. We’re not utilizing a totally different radio; it has the transmitter, similar receiver.

So the plan is when cellular is out there, we will be very aggressive in deploying it. No change in stance there. From my perspective, I’m constructing in all types of locations throughout the nation, to actually prepare for that when the September (2018) launch commonplace hardware is obtainable, which is occurring proper now. What’s going to occur is that when there’s (shopper premises gear) CPE out there on 5G NR that may do 5G House, then we’ll introduce NR gear that may do 5G House. There will be an improve path that will be pretty simple. We’re shifting ahead shortly.

On the finish of the day, there’s going to be one (Verizon) network for 5G residence and cellular. There’s not going to be two totally different networks. That’s not the plan. We’ll have one that may be scaled, with totally different attributes for various sorts of providers, that’s the best way 5G is designed.

VentureBeat: What number of clients are there proper now on 5G House broadband?

Haberman: I’d like to inform you that, however I can’t. We now have an earnings launch arising on the third or fourth week of January.

VentureBeat: Proper now, Verizon’s 5G network is strictly utilizing mmWave frequencies. AT&T and T-Cellular have espoused the worth of multi-frequency options in constructing their nationwide networks. Is the remainder of the Verizon network buildout going to be mmWave, or what frequencies past mmWave will present the power to do your nationwide buildout?

Haberman: The query is, what’s 5G, when it comes right down to it? You possibly can take 5G and attempt to put it in 600 MHz (spectrum, like T-Cellular), a lower-band frequency, however technology-wise that doesn’t do something for you. You’d wind up with a 5G NR service that might principally have worse throughput than LTE-Superior, since you wouldn’t have the ability to combination bandwidth collectively. If you wish to create a advertising message that doesn’t profit the client, you do this, however that is senseless to us. So the query is, what are you making an attempt to do with 5G?

There are actually two underlying rules with the best way 5G was designed. One is very large bandwidth, so you should have one thing on the order of a 100 MHz service for NR to begin to be significant. In any other case you’re simply speaking about LTE-Superior. And mmWave is clearly a place the place you will get a lot of bandwidth.

The second factor is antenna know-how. Whenever you take a look at mmWave, one in every of its negatives is propagation, that (its sign) doesn’t propagate as far. However one in every of its positives that’s going to grow to be very obvious is that the antenna know-how you possibly can convey to bear with mmWave is immense. You are able to do a 64- or 128-antenna array the place the beam of the antenna used to depend upon three antennas 120 levels aside.

With 5G, you possibly can have 128 antennas in the identical area, and also you’re going to have a beam that factors instantly at you to scale back interference and be sure to can talk clearly with the cell website. In order that will assist as to how far you could be away, as a result of we may be very spot on correct with the beam coming at you. You’ll be able to actually solely do that with mmWave, as a result of at greater frequencies, the array of antennas can be large.

A true 5G network must have large bandwidth and you’ve got to have the ability to use this antenna know-how. There are shades of grey, like you’ll be able to speak about mid-band and what have you ever, however the truest spec was meant to be mmWave, to reap the benefits of all of the antenna know-how. From our standpoint, what’s value taking a look at is the density of our websites in these greater cities. You’d be amazed at how dense we’re proper now.

When you have the densities required, and also you deliver within the antenna know-how, and the bandwidth, it’s like, “wow, that is a different experience.” We’re involved in offering a totally different experience, not simply extra of LTE-Superior, that’s not what we keep in mind. It’s to offer a better experience, to vary the dynamic within the business. That’s why we’re taking a look at mmWave, and we’re taking place that path, as a result of that’s really what 5G is.

VentureBeat: AT&T and T-Cellular have instructed that they will’t blanket sufficient territory with mmWave hardware to go nationwide. Is the Verizon principle going ahead that you simply’re going to maneuver slowly, however each metropolis that will get Verizon 5G will get mmWave? Or is there going to be a fallback, aside from LTE-Superior?

Haberman: Individuals have talked about sub-6 GHz. You’re going to search for alternatives like that as (5G evolves). As you get extra of the handsets which have (5G) NR functionality, then it is sensible emigrate a few of the different bandwidth you could have after which combination them collectively. The issue you’ve (now) is which you can’t combination (present spectrum) collectively since you don’t have sufficient (succesful) handsets. However as you get extra penetration of NR-capable handsets, all the sudden you are able to do issues which might be extra significant with the frequencies.

Whenever you roll out a network, which god is aware of I’ve completed this 3 times already, you’ll be able to’t simply do all the things directly. That’s why this primary step is actually the best way to go, and then you definitely’ll add parts on as you progress alongside. The statements I hear from different carriers are simply them making an attempt to understand the restrictions of what they’ve, and making an attempt to create a story that type of is sensible.

VentureBeat: So we’re not going to see from Verizon within the instant future a number of 5G flavors like “5G+” or “5G Enhanced?” It’s all going to be branded beneath the identical identify, you both have 5G or don’t?

Haberman: I can’t touch upon that at this level. Clearly we’re going to return out and clearly say what 5G is, although. It’s going to be what I simply defined to you. Any modifications which are achieved, we’ll clearly talk it. From our standpoint, we’re defining what 5G is, and it’s what I simply informed you it was. As a result of there might be a lot of confusion there.

We noticed what AT&T did with “5G E” and also you noticed the response to that — it obtained the response we’d anticipate, fairly frankly — the identical factor that occurred when AT&T upgraded from 3G to “4G” in a single day, they did the identical actual factor, and it didn’t assist them. It begs the query, “what’s different?” They’re a laggard when it comes to efficiency already, they usually simply change the identify of it and say it’s better, however it’s nonetheless worse than our LTE-Superior know-how.

That’s going to return out within the wash. Individuals are going to match 5G Evolution to LTE-Superior; I guess you some third events do it and it’s going to be slightly embarrassing when our LTE-Superior network is quicker than “5G E.” How do you clarify that?

VentureBeat: Relating to the state of your network, the place will issues be by mid-2019?

Haberman: I’d like to inform you. However all I can inform you is that we’re very aggressive, however we don’t need to tip off our rivals but as to the place we’re going. The components to make 5G work, there are actually 4 components. The primary one is densification of the network, all of the 4G densification, which has been happening for years. The second is fiber, particularly darkish fiber, as a result of if you consider the bandwidth calls for… we knew they’d get greater and better.

After which, we’ve been shopping for spectrum in millimeter wave, we purchased it from Straight Path and XO Communications. Then the fourth one, which has to cope with decreasing latency, is that we’ve been virtualizing our core. It permits you to transfer the elements of the core out to the sting of the network, so you will get fairly near the cell with core network parts, and enhance latency. Units will develop into a lot extra snappy, and it additionally allows purposes like AR/VR.

We’ve been engaged on these 4 underpinning enablers for a variety of years to make it occur, which is why we’ll going to be in a place to be very aggressive with 5G NR millimeter wave.

VentureBeat: So that you’ve constructed out this darkish fiber network and anticipate large bandwidth utilization. There have been forecasts that limitless knowledge was going to be principally essential to facilitate 5G. You’ve already provided limitless knowledge for residence broadband; is that going to be the identical factor with cellular 5G?

Haberman: We’ve got not introduced the plans for mobility and haven’t made them public but, so no touch upon the pricing plan. That will be one thing that you simply’ll see shortly.
