  • - Hey guys, this is Austin.

  • After years of using 4G,

  • 5G networks are just starting to roll out.

  • And with that we should be able to see

  • proper gigabit-class speeds.

  • But if you owned a flagship in the last couple years

  • you might have noticed something strange, a 5G E logo.

  • So, have you been using a 5G phone

  • this entire time without realizing it?

  • Yeah, no.

  • Like 4G before it, 5G is not

  • as straightforward as it might seem.

  • There are several competing 5G standards

  • being built out right now.

  • For example, here in LA you can sign up

  • for Verizon's 5G home service.

  • This is using an early version of 5G,

  • which according to Verizon is good

  • for up to 20 times the speed of LTE.

  • And in the real world,

  • delivers about 300 megabits per second down.

  • Although theoretically, it can go up to

  • 940 megabytes, completely wirelessly.

  • That's actually pretty good.

  • And it shows how 5G can be used, not only for your phone

  • and for your laptop and tablet,

  • but also it can be used to completely replace

  • a standard home internet line.

  • So putting aside for a second

  • that this isn't true 5G just yet,

  • there is a ton of potential here.

  • The final 5G spec calls for a theoretical maximum

  • of 20 gigabits per second.

  • Although realistically,

  • it's going to be much closer to one gigabit.

  • But that is still a huge huge bump over what we have today.

  • That brings us to 5G E.

  • Now this is short for 5G Evolution

  • and it is what AT&T is calling 5G.

  • Although spoiler alert, it's not 5G.

  • So to give you a better idea of what 5G E is,

  • we have a little bit of an example.

  • So, this is Pikachu.

  • And for this reference we'll call him 5G.

  • As you can see, he's very cheery, he's very happy.

  • All good, right?

  • Well, this is Mimikyu.

  • Now, on the service looks very similar to Pikachu,

  • except that he's really LTE

  • with some weird drawings on his face.

  • Clearly not the same thing.

  • Are you following?

  • Maybe I should explain this little bit better.

  • So if you take a look at the AT&T site,

  • they describe 5G E as quote,

  • "The first step on the road to 5G."

  • So it does support some additional technologies

  • that come with LTE Advanced.

  • Such as four-by-four as well as some

  • better streaming and better compression.

  • But generally speaking, this is not 5G

  • even though they're slapping that 5G badge all over it.

  • And if this all sounds familiar then you would be right.

  • Back with AT&T was transitioning from 3G to 4G,

  • they sent out an update to their phones

  • to change the badge to say 4G

  • when it was actually still on 3G.

  • Yeah, they're doing that one again.

  • So based on all of this, it seems pretty clear to me

  • that 5G E is not going to deliver

  • a true next-gen experience.

  • But to be fair, I think it's time to put it to the test.

  • So let's see if we can actually track down a 5G E phone

  • and see how it actually performs.

  • That was fun.

  • So, did not get a phone.

  • But we got some interesting information.

  • They did confirm that it does support 5G.

  • So I think the main phone I'm looking for is the V40.

  • Everything that I've read up until now seems to show

  • that that actually is one of the phones

  • that does show the 5G badge.

  • Unfortunately the store didn't get many V40s

  • and they shipped them all back

  • because they didn't sell them.

  • Oh thank you, I appreciate it.

  • So, we have an LG V40 that supports full 5G E,

  • at least I hope it does.

  • Now, I have to put a SIM card in here

  • and hope that 5G shows up

  • and I can actually test to see if it's any good

  • or whether I just spent $950 on a phone that won't work.

  • So, it is time to put a AT&T's 5G network to the test.

  • So the first bottleneck is that we actually might not have

  • 5G E service here at the office.

  • I'm hopeful that we will but they don't really exactly

  • have a whole lot of information about it.

  • So I'm gonna put a SIM card in with actual data.

  • All right, so it shows we're on AT&T on LTE,

  • which is the correct thing because we should be on LTE.

  • But I wanna see if this actually will show us 5G E.

  • This V40 does have an update released on January 4th.

  • Oh, excellent, here we go, what's new.

  • 5G Evolution indicator support added.

  • Okay, so there is an update for the phone

  • that specifically changes the indicator to 5G Evolution.

  • Now the question is, why doesn't it wanna download?

  • So we got the phone up to date

  • but unfortunately it still shows 4G LTE.

  • Now, this should theoretically show 5G.

  • The main issue is that there's not

  • 5G service here at the office.

  • So the next step is to track down 5G

  • so we actually can test to see,

  • even though it's probably gonna be the same.

  • This isn't going to be a definitive test,

  • but all I want to know is this.

  • Does 5G E make any difference whatsoever?

  • So after taking a closer look at the 5G E coverage areas,

  • one of the major spots that they do have listed

  • is Los Angeles.

  • So we're here in Hollywood to see exactly

  • whether or not this is going to work.

  • Oh, oh, 5G E, we got it.

  • I actually legitimately did not think that was gonna work.

  • So what's really interesting is

  • if you look at the actual network page,

  • what you'll see is even though it says 5G E

  • it still says LTE here because that's what it really is.

  • I guess the first test is just to see how fast it is.

  • So, 4.6 down and 16 up.

  • Hardly a gigabit like they had promised.

  • Now on the other side I have the iPhone 10R.

  • Now this is a phone which actually is

  • listed on AT&T's site as 5G E compatible.

  • But if you take a look, I have four bars of LTE, not 5G.

  • It's the same thing.

  • But let's see if there's actually a difference.

  • Oh wow.

  • (laughs breathlessly)

  • Are you serious?

  • (laughs breathlessly)

  • Are you trying to tell me that 5G is slower?

  • To be clear, these phones are both on AT&T.

  • There's no difference in any way, except that

  • this one is like 10 times faster on the download.

  • 29, 31, 35.

  • Are these settings the same?

  • Now we've gotta try like another site or something.

  • So because that seems very suspicious,

  • I'm going to try the standard Google Speed Test

  • to just see what we get.

  • All right, what have we got?

  • Oh, there we go.

  • Okay, that makes a lot more sense.

  • We're seeing way faster speeds on 5G E,

  • which makes sense if you think about it.

  • The 10R has a two-by-two LTE antenna

  • versus the four-by-four antenna on the V40.

  • Okay, let's do it one more time.

  • Ready, set.

  • There we go, yeah.

  • It's consistently pulling ahead,

  • this time actually by a lot more.

  • So the iPhone still does have

  • a little bit of an advantage on the upload.

  • But I mean the download is a big difference,

  • 5G is delivering almost double the speed.

  • Now whether or not that's worthy of the 5G badge,

  • I'm not so sure.

  • I mean realistically the goal for 5G, proper 5G,

  • is over 10 times this speed.

  • So the fact that it's a little bit faster than LTE,

  • it makes sense.

  • So, what did we learn?

  • 5G E is just another name for LTE Advanced.

  • And while it is faster, you shouldn't go drop everything

  • to buy a 5G E-enabled phone.

  • True 5G is right around the corner.
