00:00:00,000 --> 00:00:07,120
last time we partnered with t-mobile on a video about 5g you guys had some fair

2
00:00:04,560 --> 00:00:11,280
questions so we're back again sponsored by t-mobile to address them and shed

3
00:00:09,200 --> 00:00:16,960
some more light on the current state of 5g it's the weekend of this

4
00:00:14,000 --> 00:00:19,840
oh no i can't the massive contest

5
00:00:18,160 --> 00:00:24,960
and thousands of people are going to be converging on the stadium behind me some

6
00:00:22,240 --> 00:00:27,359
of them equipped with 5g phones naturally

7
00:00:26,480 --> 00:00:33,040
i am one of them so i've actually got 5g

8
00:00:30,080 --> 00:00:37,040
devices from both t-mobile and one of their competitors and i'm going to be

9
00:00:34,800 --> 00:00:42,079
checking out what the 5g coverage looks like here in the miami area so t-mobile

10
00:00:39,920 --> 00:00:47,120
is using a combination of their low-band 600 megahertz 5g and millimeter wave

11
00:00:45,440 --> 00:00:52,559
while their competitor's rollout is focused entirely on millimeter wave that

12
00:00:50,160 --> 00:00:56,559
should give us great speeds but i suspect we're gonna run into some of the

13
00:00:54,079 --> 00:01:01,039
same signal drop issues that we did last time around behind us is one of the

14
00:00:58,559 --> 00:01:04,239
event spaces for the big contest so we think that millimeter wave 5g has been

15
00:01:02,640 --> 00:01:07,760
really juiced up in this area so we're going to go ahead and cold and i are

16
00:01:05,840 --> 00:01:12,799
each going to walk walk until we drop our signal our 5g signal we're just

17
00:01:10,400 --> 00:01:15,920
walking together all right so if it picks up again you're allowed to keep

18
00:01:14,080 --> 00:01:18,799
walking you better watch out for these buildings Colton

19
00:01:22,400 --> 00:01:27,600
see you Colton nice knowing you Colton you want

20
00:01:25,600 --> 00:01:30,479
something to eat Colton Colton want something to eat and grab you something

21
00:01:29,280 --> 00:01:34,000
bring it back i'm coming back i'm coming back for you

22
00:01:33,040 --> 00:01:37,920
you know what the thing about old technology is

23
00:01:36,640 --> 00:01:43,439
it's always getting in the way of progress so i'm using my phone using my phone

24
00:01:41,680 --> 00:01:47,759
think maybe i'll relax in this very comfortable chair here

25
00:01:45,439 --> 00:01:53,840
ah see you 5g was nice knowing you

26
00:01:50,479 --> 00:01:56,479
now let's try our 5g being blocked by

27
00:01:53,840 --> 00:02:00,799
nothing i was standing here a second ago and it just went from 5g to 4g now last

28
00:01:59,119 --> 00:02:04,799
time in new york i ended up filming my video just a few days before t-mobile

29
00:02:03,119 --> 00:02:09,039
lit up their nationwide 5g network covering over half of the us population

30
00:02:06,640 --> 00:02:14,720
so i was only able to show how a millimeter wave only 5g network behaves

31
00:02:12,000 --> 00:02:19,680
it's now you see it now you don't quite literally almost any object

32
00:02:17,360 --> 00:02:23,280
between the phone and the tower drops you back to 4g

33
00:02:21,360 --> 00:02:28,319
well now let's take a look at what happens on t-mobile's low band 5g

34
00:02:26,560 --> 00:02:32,640
hold on where was exactly the spot where the other one dropped i think it was like here

35
00:02:30,640 --> 00:02:36,120
here here still got it

36
00:02:37,920 --> 00:02:46,000
my two phones here uh-oh got that glass in the way

37
00:02:42,080 --> 00:02:49,120
oh and the millimeter waves are gone

38
00:02:46,000 --> 00:02:50,959
t-mobile 5g is still working though

39
00:02:49,120 --> 00:02:55,200
still got it so this is fantastic we've had 5g

40
00:02:53,280 --> 00:03:01,519
basically everywhere we've gone today on t-mobile but the funny thing is compared

41
00:02:58,400 --> 00:03:03,040
to 4g lte we're not getting otherworldly

42
00:03:01,519 --> 00:03:07,440
speeds like it's good we're over 100 megabit but it's not insane that is

43
00:03:05,760 --> 00:03:11,840
where some of the confusion came from last time around a ton of hype

44
00:03:09,360 --> 00:03:17,040
surrounding 5g has been hyper focused on these blazing fast speeds i mean even we

45
00:03:14,879 --> 00:03:21,680
got swept up by it you know wow look at this mobile internet speed in excess of

46
00:03:19,760 --> 00:03:26,720
what most people can get to their homes it's crazy

47
00:03:23,040 --> 00:03:29,200
but 5g is a lot more than just

48
00:03:26,720 --> 00:03:34,879
speed millimeter wave so the high band frequencies between 20 gigahertz and 100

49
00:03:31,680 --> 00:03:37,440
gigahertz is an exciting new component

50
00:03:34,879 --> 00:03:42,159
of 5g because that spectrum wasn't already being used for anything carriers

51
00:03:39,519 --> 00:03:46,400
could just jump right into it bond together a huge number of channels and

52
00:03:44,560 --> 00:03:50,879
then give you these insane download speeds in excess of one gigabit per

53
00:03:48,400 --> 00:03:55,120
second but there's a reason no one was using it that performance and in fact

54
00:03:53,360 --> 00:04:00,319
any connection at all can only be achieved over short distances and within

55
00:03:57,519 --> 00:04:05,120
direct line of sight so i mean in a large stadium or a concert hall where

56
00:04:02,959 --> 00:04:09,280
tons of people are taking videos and sharing them with each other it's a

57
00:04:06,959 --> 00:04:15,200
complete game changer but the thing is that even within a single building it's

58
00:04:12,799 --> 00:04:18,400
very challenging to get perfect coverage so millimeter wave needs something else

59
00:04:17,040 --> 00:04:22,160
to fall back on oh and of course it's basically useless

60
00:04:20,400 --> 00:04:26,000
to anyone who lives outside of the select areas where it has decent

61
00:04:23,680 --> 00:04:31,199
coverage in the last video i explained that t-mobile planned to achieve a

62
00:04:28,000 --> 00:04:33,440
mixture of broad coverage high speeds

63
00:04:31,199 --> 00:04:38,000
and strong penetration power for indoor use by using high band so that's

64
00:04:35,440 --> 00:04:41,680
millimeter wave their existing low band and the mid band spectrum that they're

65
00:04:40,080 --> 00:04:48,320
planning to acquire in the future and the comments got absolutely flooded with

66
00:04:45,120 --> 00:04:52,080
this comment or some variant thereof so

67
00:04:48,320 --> 00:04:55,199
here we go 5g means 5th gen and it's not

68
00:04:52,080 --> 00:04:59,600
bound to a particular frequency range

69
00:04:55,199 --> 00:05:02,639
low band 5g is 5g mid band 5g is 5g and

70
00:04:59,600 --> 00:05:04,880
high band 5g is 5g

71
00:05:02,639 --> 00:05:10,639
as long as your device is equipped with a 5g nr or new radio and your carrier is

72
00:05:08,960 --> 00:05:16,240
using the same frequencies that your phone supports you are on 5g

73
00:05:14,320 --> 00:05:20,639
the big picture benefits looking into the future of 5g include lower latency

74
00:05:19,199 --> 00:05:27,039
which is essential for the future of autonomous cars better handling of dense pockets of

75
00:05:24,320 --> 00:05:30,720
users like at the massive sports ball competition and then

76
00:05:29,280 --> 00:05:38,160
of course faster speeds using 5g versus 4g on the same spectrum

77
00:05:36,000 --> 00:05:43,440
at the same width should yield some improvement but it just isn't the main

78
00:05:40,880 --> 00:05:46,880
point however like any new technology early adopters are going to have to wait

79
00:05:44,960 --> 00:05:52,240
a little while to see the full benefit so you shouldn't be surprised to see

80
00:05:49,120 --> 00:05:55,120
multiple 4g bands bonded together

81
00:05:52,240 --> 00:06:00,400
outperforming an early 5g deployment especially in terms of a basic speed

82
00:05:57,280 --> 00:06:01,919
test run 5g is going to keep continually

83
00:06:00,400 --> 00:06:05,600
getting better if you're going to take anything away from this video it should

84
00:06:03,440 --> 00:06:09,440
be this if all you're after is faster video downloads there's no reason to

85
00:06:07,600 --> 00:06:14,000
throw away a perfectly good 4g device today but

86
00:06:11,759 --> 00:06:18,160
this is one of those times where if you are in the market for a new phone you

87
00:06:16,560 --> 00:06:23,520
should be looking at the future-proof option t-mobile's 5g network has massive

88
00:06:20,960 --> 00:06:27,120
low band coverage today with other bands coming soon so thanks again to t-mobile

89
00:06:25,680 --> 00:06:33,680
for sponsoring this video if you guys enjoyed this one you can check out the previous one where we were walking

90
00:06:29,759 --> 00:06:33,680
around new york i'll see you guys later
