1
00:00:00.040 --> 00:00:02.960
<v Speaker 1>When you think about the infrastructure that runs the world,

2
00:00:03.160 --> 00:00:05.919
<v Speaker 1>you usually picture things you can actually physically.

3
00:00:05.480 --> 00:00:11.279
<v Speaker 2>Touch, right, like concrete highways or massive steel bridges exactly.

4
00:00:10.919 --> 00:00:14.480
<v Speaker 1>Or those giant high voltage power lines cutting across the landscape.

5
00:00:14.720 --> 00:00:17.679
<v Speaker 1>We expect our infrastructure to be heavy, we expect it

6
00:00:17.679 --> 00:00:18.640
<v Speaker 1>to be highly visible.

7
00:00:18.800 --> 00:00:19.640
<v Speaker 2>Oh absolutely.

8
00:00:19.679 --> 00:00:22.920
<v Speaker 1>But right now you and I are surrounded by an

9
00:00:22.960 --> 00:00:28.239
<v Speaker 1>infrastructure that is completely invisible. I mean it's passing through

10
00:00:28.239 --> 00:00:30.879
<v Speaker 1>the walls, through the air, even through us constantly.

11
00:00:31.000 --> 00:00:34.479
<v Speaker 2>Yeah, and it's quietly becoming the central nervous system of

12
00:00:34.520 --> 00:00:38.240
<v Speaker 2>the entire planet, which is it's a pretty profound shift,

13
00:00:38.359 --> 00:00:40.799
<v Speaker 2>It really is, because unlike a physical bridge that takes

14
00:00:40.840 --> 00:00:44.079
<v Speaker 2>decades to plan and poor, this nervous system is evolving

15
00:00:44.119 --> 00:00:47.560
<v Speaker 2>at a speed that requires a complete reimagining of computer

16
00:00:47.679 --> 00:00:49.960
<v Speaker 2>science and physics just to keep up.

17
00:00:50.079 --> 00:00:53.759
<v Speaker 1>And that evolution is exactly what we're exploring today. Welcome

18
00:00:53.880 --> 00:00:56.679
<v Speaker 1>to this deep dive. Today we are looking at a

19
00:00:56.840 --> 00:01:01.520
<v Speaker 1>really massive, incredibly detailed text called five G Mobile and

20
00:01:01.560 --> 00:01:03.399
<v Speaker 1>Wireless Communications Technology.

21
00:01:03.439 --> 00:01:06.319
<v Speaker 3>It's a foundational text, yeah, edited by some of the

22
00:01:06.400 --> 00:01:10.400
<v Speaker 3>leading telecom experts in the world of fifth Osirian jose

23
00:01:10.560 --> 00:01:14.359
<v Speaker 3>F Mansrot and Patrick marsh and the minds who contributed to.

24
00:01:14.280 --> 00:01:16.400
<v Speaker 1>This text make a pretty staggering claim.

25
00:01:16.560 --> 00:01:19.799
<v Speaker 2>They do. They argue that five G isn't just you know,

26
00:01:19.959 --> 00:01:23.640
<v Speaker 2>a telecom upgrade for your smartphone. It actually represents the

27
00:01:23.719 --> 00:01:27.200
<v Speaker 2>mechanical trigger for the fourth stage of the Industrial revolution.

28
00:01:27.480 --> 00:01:29.040
<v Speaker 1>Fourth stage wow.

29
00:01:28.959 --> 00:01:31.920
<v Speaker 2>Yeah, enabling a world where up to twenty five billion

30
00:01:32.000 --> 00:01:33.879
<v Speaker 2>devices are connected simultaneously.

31
00:01:33.959 --> 00:01:36.640
<v Speaker 1>Okay, let's unpack this because we're on a mission today

32
00:01:37.200 --> 00:01:39.519
<v Speaker 1>to look way past the marketing hype. You probably see

33
00:01:39.519 --> 00:01:42.599
<v Speaker 1>the commercials promising you can download a movie in like

34
00:01:42.879 --> 00:01:44.519
<v Speaker 1>three seconds instead of thirty.

35
00:01:44.359 --> 00:01:46.359
<v Speaker 2>Right, the usual carrier marketing.

36
00:01:46.200 --> 00:01:49.359
<v Speaker 1>Exactly, But we don't care about that today. We're going

37
00:01:49.359 --> 00:01:52.000
<v Speaker 1>to uncover how five G was engineered from the ground

38
00:01:52.040 --> 00:01:55.599
<v Speaker 1>up to be this invisible nervous system for the modern world.

39
00:01:55.719 --> 00:01:58.680
<v Speaker 2>And to really grasp why this is such a revolutionary leap,

40
00:01:58.799 --> 00:02:01.359
<v Speaker 2>we have to look at the mechanics limitations of everything

41
00:02:01.400 --> 00:02:02.159
<v Speaker 2>that came before it.

42
00:02:02.280 --> 00:02:05.519
<v Speaker 1>Yeah, let's trace that progression mechanically. Think about the jump

43
00:02:05.560 --> 00:02:08.280
<v Speaker 1>from one G in the early eighties to two G

44
00:02:08.479 --> 00:02:09.240
<v Speaker 1>in the nineties.

45
00:02:09.319 --> 00:02:13.719
<v Speaker 2>Well, one G was entirely analog systems like NMT and AMPS, right,

46
00:02:13.960 --> 00:02:14.599
<v Speaker 2>and if one G.

47
00:02:14.680 --> 00:02:17.520
<v Speaker 1>Was essentially a dirt road, and four G is a

48
00:02:17.560 --> 00:02:20.439
<v Speaker 1>modern super highway. Five G isn't just adding more lanes,

49
00:02:20.520 --> 00:02:23.960
<v Speaker 1>it's introducing an entirely new three D transportation system.

50
00:02:24.000 --> 00:02:24.840
<v Speaker 2>I like that analogy.

51
00:02:24.919 --> 00:02:27.599
<v Speaker 1>Thanks so on that one G dirt road, it was

52
00:02:27.639 --> 00:02:31.120
<v Speaker 1>basically just broadcasting a continuous frequency to carry your voice,

53
00:02:31.280 --> 00:02:34.319
<v Speaker 1>which was super prone to static. Then two G rise

54
00:02:34.400 --> 00:02:37.039
<v Speaker 1>in nineteen ninety one with GSM.

55
00:02:36.639 --> 00:02:37.639
<v Speaker 2>The shift to digital.

56
00:02:37.800 --> 00:02:40.599
<v Speaker 1>Right, the network started chopping your voice down into binary

57
00:02:40.599 --> 00:02:43.520
<v Speaker 1>code ones and zeros that gave us better voice quality

58
00:02:43.680 --> 00:02:46.560
<v Speaker 1>and SMS text messaging. Then three G and three point

59
00:02:46.560 --> 00:02:50.240
<v Speaker 1>five G arrived, bringing WCDMA and HSPA. We saw the

60
00:02:50.360 --> 00:02:51.840
<v Speaker 1>dawn of packet data.

61
00:02:51.599 --> 00:02:54.639
<v Speaker 2>And that was the crucial pivot because previously the network

62
00:02:54.680 --> 00:02:58.520
<v Speaker 2>held a dedicated physical circuit open for the entire duration.

63
00:02:58.240 --> 00:02:59.879
<v Speaker 1>Of your clock, which is incredibly in a.

64
00:03:00.479 --> 00:03:03.319
<v Speaker 2>Exactly Packet data, on the other hand, takes your information,

65
00:03:03.719 --> 00:03:06.800
<v Speaker 2>slices it into thousands of tiny independent envelopes, and just

66
00:03:06.840 --> 00:03:08.719
<v Speaker 2>shoots them all through the network dynamically and.

67
00:03:08.719 --> 00:03:11.240
<v Speaker 1>Then reassembles them at the destination, which obviously paved the

68
00:03:11.280 --> 00:03:13.400
<v Speaker 1>way for the four GLT networks we use today.

69
00:03:13.479 --> 00:03:15.960
<v Speaker 2>Yeah, long term evolution right, four G.

70
00:03:16.120 --> 00:03:19.639
<v Speaker 1>Took that packet switching concept and moved it entirely to

71
00:03:19.719 --> 00:03:23.680
<v Speaker 1>an IP based standard. It essentially turned the cellular network

72
00:03:23.759 --> 00:03:26.120
<v Speaker 1>into an extension of the Internet itself.

73
00:03:25.759 --> 00:03:29.000
<v Speaker 2>Which gave us currier aggregation and peaks of three gigabits

74
00:03:29.039 --> 00:03:32.599
<v Speaker 2>per second, moving us totally away from that old circuit

75
00:03:32.599 --> 00:03:33.680
<v Speaker 2>switched functionality.

76
00:03:33.759 --> 00:03:37.240
<v Speaker 1>Yeah, giving us the speeds necessary for streaming music, video calling,

77
00:03:38.039 --> 00:03:39.759
<v Speaker 1>basically the entire happy economy.

78
00:03:39.840 --> 00:03:41.960
<v Speaker 2>But there is a massive caveat to all of this.

79
00:03:42.159 --> 00:03:45.240
<v Speaker 2>What's that The reason for the radical architectural shift to

80
00:03:45.280 --> 00:03:48.599
<v Speaker 2>five G goes back to a fundamental bottleneck. From one

81
00:03:48.680 --> 00:03:51.840
<v Speaker 2>G all the way through four G, the absolute defining

82
00:03:51.919 --> 00:03:54.960
<v Speaker 2>design priority was human centric communication.

83
00:03:55.240 --> 00:03:57.159
<v Speaker 1>Ah okay, human centric right.

84
00:03:57.199 --> 00:03:59.719
<v Speaker 2>Getting humans connected to each other and then to the Internet.

85
00:04:00.120 --> 00:04:04.439
<v Speaker 2>The entire architecture was built around human behavior, human reaction times,

86
00:04:04.639 --> 00:04:05.840
<v Speaker 2>and human consumption.

87
00:04:06.520 --> 00:04:09.400
<v Speaker 1>So engineering the network for a person tapping a screen

88
00:04:09.439 --> 00:04:11.840
<v Speaker 1>and waiting, say half a second for a web page

89
00:04:11.840 --> 00:04:12.360
<v Speaker 1>to load.

90
00:04:12.360 --> 00:04:15.319
<v Speaker 2>Exactly, which brings us to the fundamental pivot of five G.

91
00:04:15.719 --> 00:04:20.000
<v Speaker 2>It is the very first network generation designed primarily for machines.

92
00:04:20.319 --> 00:04:22.480
<v Speaker 1>Okay, So it's a network built for machines. That is

93
00:04:22.519 --> 00:04:23.800
<v Speaker 1>a huge shift.

94
00:04:24.000 --> 00:04:26.920
<v Speaker 2>It's the core thesis of the authors. It's why they

95
00:04:26.920 --> 00:04:30.639
<v Speaker 2>position five G as the engine of the fourth Industrial Revolution.

96
00:04:30.920 --> 00:04:33.800
<v Speaker 1>Let's quickly review those revolutions for context. We all know

97
00:04:33.839 --> 00:04:37.240
<v Speaker 1>the textbook narrative, right. The first stage around seventeen sixty

98
00:04:37.279 --> 00:04:40.079
<v Speaker 1>to eighteen forty was steam engines and the power loom,

99
00:04:40.199 --> 00:04:41.879
<v Speaker 1>mechanizing physical labor. Right.

100
00:04:42.199 --> 00:04:45.480
<v Speaker 2>Then the second stage eighteen forty to roughly nineteen fourteen

101
00:04:45.600 --> 00:04:49.319
<v Speaker 2>brings bessemer steel, electrification and mass production.

102
00:04:49.759 --> 00:04:51.959
<v Speaker 1>Then the third stage kicks off in the nineteen fifties

103
00:04:52.000 --> 00:04:58.480
<v Speaker 1>electronics it programmable logic controllers basically early computers automating the assembly.

104
00:04:58.160 --> 00:05:01.600
<v Speaker 2>Line, which leads us to today the fourth stage, the

105
00:05:01.639 --> 00:05:04.879
<v Speaker 2>era of cyber physical systems or CPS and the Internet

106
00:05:04.959 --> 00:05:06.040
<v Speaker 2>of Things the IoT.

107
00:05:06.519 --> 00:05:09.920
<v Speaker 1>When you hear cyberphysical systems, think about the complete integration

108
00:05:09.959 --> 00:05:13.120
<v Speaker 1>of computer logic with actual physical processes in the real world.

109
00:05:13.279 --> 00:05:14.920
<v Speaker 2>Yeah, like a smart power grid.

110
00:05:14.720 --> 00:05:18.199
<v Speaker 1>Exactly, a grid that instantly reroutes electricity across an entire

111
00:05:18.240 --> 00:05:20.720
<v Speaker 1>city based on real time spikes and demand.

112
00:05:20.920 --> 00:05:23.759
<v Speaker 2>If we connect this to the bigger picture, the information

113
00:05:23.839 --> 00:05:28.160
<v Speaker 2>and communications technology sector we call ICT was originally born

114
00:05:28.240 --> 00:05:32.399
<v Speaker 2>from merging telecommunications with computing, but five G forces those

115
00:05:32.480 --> 00:05:36.600
<v Speaker 2>two fields to fully collapse into one another. The computing

116
00:05:36.639 --> 00:05:40.279
<v Speaker 2>and storage are actually moving to the network edge, blurring

117
00:05:40.279 --> 00:05:43.079
<v Speaker 2>the line between a communication network and a computer.

118
00:05:43.560 --> 00:05:45.959
<v Speaker 1>Just to clarify the jargon for you listening, you'll hear

119
00:05:46.079 --> 00:05:50.279
<v Speaker 1>terms like IoT or CPS or M two M which

120
00:05:50.319 --> 00:05:53.319
<v Speaker 1>stands for a machine to machine. They all essentially describe

121
00:05:53.360 --> 00:05:54.759
<v Speaker 1>the same incoming reality.

122
00:05:55.040 --> 00:05:58.519
<v Speaker 2>Yeah, connecting twenty five billion devices by twenty twenty.

123
00:05:58.360 --> 00:06:01.600
<v Speaker 1>Which is just a mind body number. Let's talk about

124
00:06:01.600 --> 00:06:03.360
<v Speaker 1>the physics of that, because this is where the source

125
00:06:03.399 --> 00:06:07.120
<v Speaker 1>material gets deeply fascinating. To me. Supporting twenty five billion

126
00:06:07.120 --> 00:06:10.600
<v Speaker 1>devices isn't just a matter scaling up the old servers,

127
00:06:10.639 --> 00:06:11.199
<v Speaker 1>not at all.

128
00:06:11.279 --> 00:06:13.199
<v Speaker 2>The designers of five G had to map out an

129
00:06:13.279 --> 00:06:17.480
<v Speaker 2>architecture that could accommodate radically conflicting needs simultaneously, and.

130
00:06:17.439 --> 00:06:20.720
<v Speaker 1>They mapped these requirements using something called a spider diagram

131
00:06:21.040 --> 00:06:23.160
<v Speaker 1>from the IMT twenty twenty standard. Right.

132
00:06:23.240 --> 00:06:26.600
<v Speaker 2>Yes, comparing five G against IMT Advanced, which is four G.

133
00:06:27.040 --> 00:06:29.959
<v Speaker 2>The diagram visually demonstrates how the new network has to

134
00:06:30.000 --> 00:06:33.199
<v Speaker 2>stretch massively in multiple completely opposing directions.

135
00:06:33.279 --> 00:06:35.079
<v Speaker 1>I want to play Devil's advocate and push back on

136
00:06:35.120 --> 00:06:37.240
<v Speaker 1>these extremes. For a second. My current four G LT

137
00:06:37.560 --> 00:06:39.920
<v Speaker 1>is already pretty fast. I can sit on a train

138
00:06:40.040 --> 00:06:43.079
<v Speaker 1>and stream a high definition movie without much buffering. So

139
00:06:43.160 --> 00:06:45.839
<v Speaker 1>when you engineers say five G needs to handle ten

140
00:06:45.879 --> 00:06:48.319
<v Speaker 1>to twenty gigabits per second, I don't know. Do we

141
00:06:48.319 --> 00:06:50.839
<v Speaker 1>really need a system built for that kind of extreme capacity.

142
00:06:51.040 --> 00:06:54.199
<v Speaker 2>It absolutely sounds like overkill if you're strictly thinking about

143
00:06:54.240 --> 00:06:57.439
<v Speaker 2>watching videos on a smartphone. Right, But that specific metric

144
00:06:57.600 --> 00:07:02.120
<v Speaker 2>on the spider diagram, extreme mobile broadband or XMBB, isn't

145
00:07:02.160 --> 00:07:06.120
<v Speaker 2>just for downloading movies. It's needed for human centric applications

146
00:07:06.160 --> 00:07:10.439
<v Speaker 2>of the future like fully immersive, real time, augmented and

147
00:07:10.519 --> 00:07:11.399
<v Speaker 2>virtual reality.

148
00:07:11.439 --> 00:07:14.680
<v Speaker 1>Oh like streaming the four K three D world instantly.

149
00:07:14.319 --> 00:07:18.600
<v Speaker 2>Exactly, or four K media on demand everywhere. But XMBB

150
00:07:18.759 --> 00:07:21.759
<v Speaker 2>is only one arm of that spider diagram. Let's look

151
00:07:21.759 --> 00:07:24.480
<v Speaker 2>at the requirement that I find most mind bending latency,

152
00:07:24.600 --> 00:07:27.360
<v Speaker 2>the delay in the network. Right, the textbook states five

153
00:07:27.439 --> 00:07:30.199
<v Speaker 2>G requires a staggering one millisecond latency.

154
00:07:30.279 --> 00:07:33.800
<v Speaker 1>Wait one millisecond human reaction time is roughly what two

155
00:07:33.920 --> 00:07:35.560
<v Speaker 1>hundred milliseconds roughly?

156
00:07:35.680 --> 00:07:39.600
<v Speaker 2>Yeah, so a one millisecond delay is so extraordinarily low

157
00:07:39.759 --> 00:07:43.480
<v Speaker 2>that our biological nervous systems simply cannot detect it. The

158
00:07:43.519 --> 00:07:47.879
<v Speaker 2>authors refer to this as the enabler for the tactile Internet.

159
00:07:48.040 --> 00:07:50.000
<v Speaker 1>The tactile Internet, that's a great phrase.

160
00:07:50.120 --> 00:07:53.560
<v Speaker 2>It means you can essentially feel something over the Internet

161
00:07:53.680 --> 00:07:56.839
<v Speaker 2>through haptic feedback, and your brain will perceive it as

162
00:07:56.879 --> 00:07:59.399
<v Speaker 2>happening instantaneously in your physical space.

163
00:07:59.600 --> 00:08:02.360
<v Speaker 1>But how oh is a one millisecond round trip even

164
00:08:02.480 --> 00:08:06.199
<v Speaker 1>physically possible? I mean, light travels fast, but it still

165
00:08:06.240 --> 00:08:09.040
<v Speaker 1>takes time to move through fiber optic cables. If a

166
00:08:09.079 --> 00:08:11.199
<v Speaker 1>signal has to cross the country to a server and

167
00:08:11.199 --> 00:08:14.199
<v Speaker 1>come back, the laws of physics dictate it will take

168
00:08:14.240 --> 00:08:15.560
<v Speaker 1>longer than one millisecond.

169
00:08:15.800 --> 00:08:18.800
<v Speaker 2>The physics dictate exactly that, which means the architecture of

170
00:08:18.800 --> 00:08:22.319
<v Speaker 2>the network itself had to fundamentally change. You cannot send

171
00:08:22.439 --> 00:08:25.680
<v Speaker 2>life critical data to a centralized cloud server thousands of

172
00:08:25.759 --> 00:08:27.480
<v Speaker 2>miles away and wait for a response.

173
00:08:27.720 --> 00:08:28.519
<v Speaker 1>So what's the solution?

174
00:08:29.160 --> 00:08:32.960
<v Speaker 2>Five G utilizes mobile edge computing. It physically moves the

175
00:08:33.000 --> 00:08:36.399
<v Speaker 2>computing power, the artificial intelligence, and the storage out of

176
00:08:36.399 --> 00:08:39.200
<v Speaker 2>those distant data centers and pushes it right to the

177
00:08:39.320 --> 00:08:40.399
<v Speaker 2>very edge of the network.

178
00:08:40.600 --> 00:08:44.440
<v Speaker 1>So the local cell tower essentially becomes a miniaturized Amazon

179
00:08:44.480 --> 00:08:46.480
<v Speaker 1>Web Services data center exactly.

180
00:08:46.559 --> 00:08:50.200
<v Speaker 2>The processing happens locally, circumventing the geographic latency problem.

181
00:08:50.240 --> 00:08:53.639
<v Speaker 1>Okay, so we have massive broadband capacity and sub millisecond

182
00:08:53.799 --> 00:08:57.399
<v Speaker 1>physics defying latency through edge computing. What else is on.

183
00:08:57.440 --> 00:09:01.799
<v Speaker 2>That spider diagram connection density? The five G standard mandates

184
00:09:01.840 --> 00:09:05.879
<v Speaker 2>the ability to support up to one million individual devices

185
00:09:05.919 --> 00:09:07.399
<v Speaker 2>per single square kilometer.

186
00:09:07.679 --> 00:09:12.559
<v Speaker 1>One million devices in one square kilometer that is, I mean,

187
00:09:12.720 --> 00:09:15.360
<v Speaker 1>think about the sheer density of a modern smart city,

188
00:09:15.840 --> 00:09:19.720
<v Speaker 1>every single street lamp, parking meter, autonous vehicle health monitor,

189
00:09:20.080 --> 00:09:21.720
<v Speaker 1>all communicating continuously.

190
00:09:21.799 --> 00:09:25.679
<v Speaker 2>A four G network would instantly buckle under that localized volume.

191
00:09:25.720 --> 00:09:28.840
<v Speaker 2>And then you have to add the final extreme variable mobility.

192
00:09:28.519 --> 00:09:30.799
<v Speaker 1>Right maintaining a flawless connection while moving fast.

193
00:09:30.840 --> 00:09:33.759
<v Speaker 2>The standard requires maintaining quality of service that speeds up

194
00:09:33.759 --> 00:09:35.320
<v Speaker 2>to five hundred kilometers per.

195
00:09:35.159 --> 00:09:37.799
<v Speaker 1>Hour, so high speed bullet trains. The network has to

196
00:09:37.840 --> 00:09:41.399
<v Speaker 1>manage massive data, zero delay, and a million devices, all

197
00:09:41.399 --> 00:09:43.600
<v Speaker 1>while handing off the connection from tower to tower at

198
00:09:43.639 --> 00:09:44.840
<v Speaker 1>five hundred kilometers.

199
00:09:44.559 --> 00:09:47.440
<v Speaker 2>Per hour without dropping a single packet of data.

200
00:09:48.000 --> 00:09:51.440
<v Speaker 1>Here's where it gets really interesting. Let's take these abstract

201
00:09:51.440 --> 00:09:55.480
<v Speaker 1>theoretical engineering requirements and drop them into real world use cases.

202
00:09:55.799 --> 00:09:59.759
<v Speaker 2>The textbook explores factory sell automation as a primary scenario.

203
00:10:00.320 --> 00:10:03.840
<v Speaker 1>My immediate thought reading that was why bother with wireless

204
00:10:03.840 --> 00:10:07.519
<v Speaker 1>at all in a factory? If you're building cars or microchips,

205
00:10:07.840 --> 00:10:11.679
<v Speaker 1>wired networks are completely reliable, why go through the immense

206
00:10:11.759 --> 00:10:14.759
<v Speaker 1>technical hurdle of building a five G wireless system for

207
00:10:14.799 --> 00:10:15.720
<v Speaker 1>a factory floor.

208
00:10:16.080 --> 00:10:21.399
<v Speaker 2>Because physical wires are the enemy of modern industrial flexibility. Also, well,

209
00:10:21.600 --> 00:10:26.120
<v Speaker 2>wiring a massive industrial facility costs millions of dollars. More importantly,

210
00:10:26.159 --> 00:10:28.720
<v Speaker 2>if market demands shift and you need to reconfigure your

211
00:10:28.720 --> 00:10:31.480
<v Speaker 2>assembly line to produce a different product, tearing out and

212
00:10:31.519 --> 00:10:35.120
<v Speaker 2>reinstalling physical wires can halt production for weeks or months.

213
00:10:35.240 --> 00:10:38.080
<v Speaker 1>Oh I see, So five G allows a manufacturer to

214
00:10:38.159 --> 00:10:41.919
<v Speaker 1>completely redesign a factory floor over a weekend, just by

215
00:10:41.919 --> 00:10:43.480
<v Speaker 1>wheeling the robotic stations to.

216
00:10:43.440 --> 00:10:46.879
<v Speaker 2>Different areas precisely. And previously you couldn't do that wirelessly

217
00:10:46.919 --> 00:10:51.440
<v Speaker 2>because older networks couldn't guarantee what engineers call life critical reliability.

218
00:10:51.799 --> 00:10:54.639
<v Speaker 1>Right, Because if you have multi ton robotic arms swinging

219
00:10:54.639 --> 00:10:58.639
<v Speaker 1>around at lightning speed, coordinating wirelessly, a single dropped packet

220
00:10:58.639 --> 00:11:01.720
<v Speaker 1>of data doesn't just mean of video buffers.

221
00:11:01.360 --> 00:11:05.399
<v Speaker 2>It means a catastrophic physical collision on the assembly line.

222
00:11:05.559 --> 00:11:09.600
<v Speaker 2>Five G provides that ultra low latency and absolute reliability

223
00:11:09.879 --> 00:11:12.960
<v Speaker 2>that historically only a physical wire could guarantee.

224
00:11:13.000 --> 00:11:17.759
<v Speaker 1>That concept of life. Critical reliability brings us to remote surgery,

225
00:11:17.799 --> 00:11:20.080
<v Speaker 1>which we touched on earlier with the tactile Internet.

226
00:11:20.200 --> 00:11:22.960
<v Speaker 2>It's truly staggering to visualize it really is.

227
00:11:23.279 --> 00:11:26.759
<v Speaker 1>You have a specialist performing an incredibly delicate procedure from AFAR,

228
00:11:27.399 --> 00:11:31.679
<v Speaker 1>relying on that sub millisecond haptic feedback to actually feel

229
00:11:31.679 --> 00:11:35.440
<v Speaker 1>the physical resistance of human tissue through their surgical.

230
00:11:34.960 --> 00:11:38.240
<v Speaker 2>Interface, and if the network stutters for even a fraction

231
00:11:38.279 --> 00:11:40.519
<v Speaker 2>of a second while they are making an incision.

232
00:11:40.360 --> 00:11:43.440
<v Speaker 1>It could mean life or death. The invisible infrastructure has

233
00:11:43.440 --> 00:11:46.279
<v Speaker 1>to be as dependable as a steel scalpel held directly

234
00:11:46.279 --> 00:11:47.000
<v Speaker 1>in the hand.

235
00:11:47.279 --> 00:11:50.639
<v Speaker 2>And that identical level of flawless reliability extends to another

236
00:11:50.639 --> 00:11:55.399
<v Speaker 2>critical scenario detailed in the research Emergency Communications oh.

237
00:11:55.320 --> 00:11:59.960
<v Speaker 1>Right disaster recovery. When a massive earthquake strikes, the first

238
00:12:00.080 --> 00:12:04.799
<v Speaker 1>thing to fail is traditional physical infrastructure cell tower's collapse.

239
00:12:05.000 --> 00:12:08.320
<v Speaker 2>The source material highlights how five G addresses this by

240
00:12:08.360 --> 00:12:12.200
<v Speaker 2>allowing individual user devices to act as temporary ad hoc

241
00:12:12.440 --> 00:12:13.639
<v Speaker 2>relay nodes.

242
00:12:13.600 --> 00:12:16.480
<v Speaker 1>So it creates an instantaneous mesh network out of the

243
00:12:16.519 --> 00:12:17.559
<v Speaker 1>surviving devices.

244
00:12:17.639 --> 00:12:20.159
<v Speaker 2>Exactly, if your phone is trapped in the rubble and

245
00:12:20.159 --> 00:12:22.960
<v Speaker 2>can't reach a surviving cell tower, it can ping the

246
00:12:23.000 --> 00:12:24.679
<v Speaker 2>phone of someone walking above.

247
00:12:24.440 --> 00:12:27.120
<v Speaker 1>The debris, which pings a smart meter down the street,

248
00:12:27.480 --> 00:12:30.320
<v Speaker 1>bouncing the signal from device to device until it finds

249
00:12:30.320 --> 00:12:32.879
<v Speaker 1>a working access point to the broader Internet.

250
00:12:32.559 --> 00:12:37.919
<v Speaker 2>Which introduces yet another severe engineering constraint, extreme energy efficiency

251
00:12:38.000 --> 00:12:40.799
<v Speaker 2>ah because of the battery right, If a device is

252
00:12:40.840 --> 00:12:43.960
<v Speaker 2>trapped with the survivor beneath a collapsed building, it needs

253
00:12:43.960 --> 00:12:47.720
<v Speaker 2>to minimize power consumption. The five G protocol lets these

254
00:12:47.720 --> 00:12:51.679
<v Speaker 2>devices sleep and wake in incredibly precise microbursts, so.

255
00:12:51.639 --> 00:12:54.000
<v Speaker 1>A battery that would normally die in a day can

256
00:12:54.039 --> 00:12:56.519
<v Speaker 1>broadcast a survival beacon for much much longer.

257
00:12:56.879 --> 00:13:02.120
<v Speaker 2>Exactly, it's a localized self healing mesas network, and the

258
00:13:02.200 --> 00:13:04.840
<v Speaker 2>volume challenges we discussed earlier apply here too, but in

259
00:13:04.879 --> 00:13:07.320
<v Speaker 2>different contexts, like large outdoor.

260
00:13:06.960 --> 00:13:10.360
<v Speaker 1>Events like a massive stadium concert, you have eighty thousand

261
00:13:10.360 --> 00:13:13.879
<v Speaker 1>people crammed into a single concrete bowl, all trying to

262
00:13:14.000 --> 00:13:17.360
<v Speaker 1>upload a high definition video at the exact same second

263
00:13:18.000 --> 00:13:21.279
<v Speaker 1>on four G, your phone just displays a spinning wheel

264
00:13:21.320 --> 00:13:21.759
<v Speaker 1>of death.

265
00:13:21.960 --> 00:13:26.679
<v Speaker 2>Because four G operates like a massive floodlight blasting signal everywhere.

266
00:13:27.080 --> 00:13:31.039
<v Speaker 2>Five G utilizes technologies like massive MIMO and beam forming.

267
00:13:30.720 --> 00:13:32.960
<v Speaker 1>Which act more like synchronized laser beams right.

268
00:13:32.840 --> 00:13:38.320
<v Speaker 2>Exactly dynamically steering dedicated, highly concentrated signals directly to individual devices,

269
00:13:38.360 --> 00:13:41.759
<v Speaker 2>slicing right through the interference of those eighty thousand competing phones.

270
00:13:41.840 --> 00:13:45.080
<v Speaker 1>Incredible, And because these use cases are so profoundly woven

271
00:13:45.080 --> 00:13:48.320
<v Speaker 1>into the physical, safety and economic engine of society, the

272
00:13:48.399 --> 00:13:51.159
<v Speaker 1>role out of five G isn't just a corporate tech upgrade.

273
00:13:51.240 --> 00:13:54.759
<v Speaker 2>No, it's a highly aggressive, deeply competitive global race.

274
00:13:55.039 --> 00:13:58.960
<v Speaker 1>The economic and geopolitical stakes for establishing the foundational patents

275
00:13:58.960 --> 00:14:03.519
<v Speaker 1>and infrastructure of five are nearly impossible to overstate. The

276
00:14:03.559 --> 00:14:07.840
<v Speaker 1>textbook thoroughly documents the massive initiatives launched globally to drive this.

277
00:14:08.000 --> 00:14:10.120
<v Speaker 2>Yeah, the push was tremendous across the board.

278
00:14:10.240 --> 00:14:14.120
<v Speaker 1>Europe aggressively pushed research through projects like Metis and the

279
00:14:14.159 --> 00:14:17.720
<v Speaker 1>five GPPP, which had a one point four billion euro.

280
00:14:17.519 --> 00:14:18.799
<v Speaker 2>Budget massive investment.

281
00:14:18.960 --> 00:14:23.000
<v Speaker 1>China mobilized the IMT twenty twenty Promotion Group. South Korea

282
00:14:23.120 --> 00:14:25.559
<v Speaker 1>formed the five G Forum with a mandate to have

283
00:14:25.639 --> 00:14:29.320
<v Speaker 1>functional trials for the twenty eighteen Winter Olympics, and Japan

284
00:14:29.440 --> 00:14:32.120
<v Speaker 1>mobilized the AIRB twenty twenty and beyond.

285
00:14:31.759 --> 00:14:35.120
<v Speaker 2>Group, every major economic power recognized they had to own

286
00:14:35.159 --> 00:14:38.600
<v Speaker 2>the infrastructure of the Fourth Industrial Revolution. But this raises

287
00:14:38.639 --> 00:14:41.159
<v Speaker 2>an important question, perhaps the most critical question in the

288
00:14:41.279 --> 00:14:44.000
<v Speaker 2>entire source text, which is what happens when a network

289
00:14:44.039 --> 00:14:48.360
<v Speaker 2>of this magnitude is compromised. The security imperative cannot afford

290
00:14:48.440 --> 00:14:49.039
<v Speaker 2>to fail.

291
00:14:48.879 --> 00:14:51.840
<v Speaker 1>Right, because we aren't just talking about stolen passwords anymore.

292
00:14:52.000 --> 00:14:56.879
<v Speaker 2>With earlier generations of wireless networks, security vulnerabilities were primarily

293
00:14:56.919 --> 00:15:00.679
<v Speaker 2>restricted to the digital domain. A breach meant data theft

294
00:15:00.840 --> 00:15:02.879
<v Speaker 2>someone intercepting your credit card or.

295
00:15:02.720 --> 00:15:04.679
<v Speaker 1>Reading emails damaging, for sure.

296
00:15:05.000 --> 00:15:09.440
<v Speaker 2>But five G actively controls physical machinery. In the real world.

297
00:15:10.159 --> 00:15:14.240
<v Speaker 2>We are talking about robotic arms on factory floors, smartlocks

298
00:15:14.320 --> 00:15:18.360
<v Speaker 2>on municipal water plants, and autonomous vehicles making split second

299
00:15:18.399 --> 00:15:19.360
<v Speaker 2>breaking decisions.

300
00:15:19.559 --> 00:15:22.879
<v Speaker 1>So a network breach on five G immediately becomes a

301
00:15:23.000 --> 00:15:24.399
<v Speaker 1>kinetic physical threat.

302
00:15:24.559 --> 00:15:28.519
<v Speaker 2>Exactly if someone hacks the communication network governing autonomous cars,

303
00:15:28.559 --> 00:15:31.879
<v Speaker 2>it's not identity theft, it's a physical multi car pile

304
00:15:31.960 --> 00:15:33.080
<v Speaker 2>up on the highway.

305
00:15:32.759 --> 00:15:35.519
<v Speaker 1>So the system must be able to instantly identify and

306
00:15:35.720 --> 00:15:39.399
<v Speaker 1>entirely repudiate false emergency brake messages before they reach the

307
00:15:39.480 --> 00:15:40.279
<v Speaker 1>vehicle's computer.

308
00:15:40.399 --> 00:15:43.879
<v Speaker 2>The network has to mathematically guarantee the absolute integrity and

309
00:15:43.919 --> 00:15:47.360
<v Speaker 2>authenticity of the transmitted information every single millisecond.

310
00:15:47.480 --> 00:15:50.519
<v Speaker 1>I want to highlight another much more insidious dager detailed

311
00:15:50.519 --> 00:15:54.039
<v Speaker 1>than the text too. The thread of Data Fusion five

312
00:15:54.120 --> 00:15:57.519
<v Speaker 1>G is designed to transport massive oceans of data from

313
00:15:57.519 --> 00:16:01.320
<v Speaker 1>the Internet of Things. Now, any individual message from a

314
00:16:01.360 --> 00:16:04.120
<v Speaker 1>single sensor might seem completely harmless.

315
00:16:03.720 --> 00:16:07.639
<v Speaker 2>Right sure, Like a smart thermostat recording a slight temperature

316
00:16:07.639 --> 00:16:11.320
<v Speaker 2>increase in a living room, or a wearable fitness tracker

317
00:16:11.399 --> 00:16:12.600
<v Speaker 2>noting a resting heart rate.

318
00:16:12.960 --> 00:16:15.519
<v Speaker 1>Right, who cares If that gets intercepted.

319
00:16:15.200 --> 00:16:19.960
<v Speaker 2>Individually, that data is meaningless. But if a sophisticated actor

320
00:16:20.080 --> 00:16:24.720
<v Speaker 2>intercepts the data from thousands of these trivial, seemingly disconnected devices,

321
00:16:25.320 --> 00:16:28.480
<v Speaker 2>they can fuse those data points together using machine learning,

322
00:16:28.519 --> 00:16:32.519
<v Speaker 2>right exactly, using machine learning to reveal highly sensitive, incredibly

323
00:16:32.600 --> 00:16:33.559
<v Speaker 2>private patterns.

324
00:16:33.679 --> 00:16:36.200
<v Speaker 1>So they don't just know your living room temperature, they

325
00:16:36.240 --> 00:16:38.120
<v Speaker 1>know exactly what time you get home, what room you

326
00:16:38.159 --> 00:16:41.320
<v Speaker 1>spend the most time in your caloric intake schedule, and

327
00:16:41.360 --> 00:16:42.279
<v Speaker 1>whether you live alone.

328
00:16:42.360 --> 00:16:45.159
<v Speaker 2>And if they fuse the IoT data of an entire

329
00:16:45.200 --> 00:16:48.919
<v Speaker 2>manufacturing facility, they don't just know the temperature or a machine,

330
00:16:49.080 --> 00:16:51.360
<v Speaker 2>They know when the factory's workflow.

331
00:16:51.000 --> 00:16:54.720
<v Speaker 1>Changes, potentially revealing a pivot to a new seature product line.

332
00:16:54.799 --> 00:16:58.759
<v Speaker 2>The security architecture must prevent that kind of overarching synthesis,

333
00:16:59.559 --> 00:17:02.000
<v Speaker 2>establishishing absolute trust at every layer.

334
00:17:02.279 --> 00:17:06.720
<v Speaker 1>And that requirement for absolute trust becomes incredibly complex when

335
00:17:06.720 --> 00:17:09.920
<v Speaker 1>you consider the ad hoc METS networks we discussed for

336
00:17:10.039 --> 00:17:13.440
<v Speaker 1>emergency situations. It really does, because if my smartphone is

337
00:17:13.480 --> 00:17:16.799
<v Speaker 1>suddenly acting as a temporary relay node passing your sensitive

338
00:17:16.839 --> 00:17:20.119
<v Speaker 1>medical data or your emergency beacon down the line, the

339
00:17:20.160 --> 00:17:23.200
<v Speaker 1>network has to be mathematically certain that my phone isn't

340
00:17:23.240 --> 00:17:25.359
<v Speaker 1>secretly reading or altering your data.

341
00:17:25.480 --> 00:17:28.400
<v Speaker 2>It demands a paradigm where trust is constantly verified at

342
00:17:28.400 --> 00:17:30.440
<v Speaker 2>the edge of the network, preventing man in the middle

343
00:17:30.440 --> 00:17:31.400
<v Speaker 2>attacks entirely.

344
00:17:31.720 --> 00:17:34.079
<v Speaker 1>So what does this all mean when we take a

345
00:17:34.119 --> 00:17:36.319
<v Speaker 1>step back and look at the entirety of this textbook

346
00:17:37.160 --> 00:17:40.440
<v Speaker 1>tracing the evolution from analog voice signals on a one

347
00:17:40.519 --> 00:17:44.240
<v Speaker 1>G dirt road through the extreme demands of the IMT

348
00:17:44.440 --> 00:17:48.119
<v Speaker 1>twenty twenty spider diagram, all the way to localized edge

349
00:17:48.119 --> 00:17:50.400
<v Speaker 1>computing enabling remote surgery.

350
00:17:50.480 --> 00:17:53.000
<v Speaker 2>It becomes abundantly clear that five G is not an

351
00:17:53.000 --> 00:17:53.960
<v Speaker 2>incremental upgrade.

352
00:17:54.079 --> 00:17:57.519
<v Speaker 1>No, it's the foundational infrastructure for the Fourth Industrial Revolution,

353
00:17:57.960 --> 00:18:00.000
<v Speaker 1>bridging the gap between the digital and the physics.

354
00:18:00.480 --> 00:18:03.319
<v Speaker 2>We have transitioned from a network design to help people

355
00:18:03.440 --> 00:18:06.079
<v Speaker 2>talk to other people to a network designed to help

356
00:18:06.240 --> 00:18:09.480
<v Speaker 2>every single physical object on Earth talk to every other.

357
00:18:09.319 --> 00:18:13.440
<v Speaker 1>Object in real time without human intervention. And that transition

358
00:18:13.519 --> 00:18:16.279
<v Speaker 1>leaves me with a final thought, an idea pulled from

359
00:18:16.279 --> 00:18:19.680
<v Speaker 1>the implications of all this research that I want you

360
00:18:20.440 --> 00:18:22.440
<v Speaker 1>listening right now to ponder.

361
00:18:23.000 --> 00:18:24.680
<v Speaker 2>It's a fascinating implication.

362
00:18:24.920 --> 00:18:29.519
<v Speaker 1>If five G succeeds in its ultimate goal, connecting physical objects, vehicles,

363
00:18:29.880 --> 00:18:32.759
<v Speaker 1>and our own biological health monitors with a latency so

364
00:18:32.920 --> 00:18:36.920
<v Speaker 1>low our brains cannot perceive the delayout, does the distinction

365
00:18:37.000 --> 00:18:40.359
<v Speaker 1>between the real physical world and the digital cyber network

366
00:18:40.839 --> 00:18:43.319
<v Speaker 1>effectively cease to exist for human perception.

367
00:18:43.480 --> 00:18:45.759
<v Speaker 2>If the latency drops to zero, the boundary between the

368
00:18:45.759 --> 00:18:47.880
<v Speaker 2>physical and the digital essentially vanishes.

369
00:18:48.000 --> 00:18:50.400
<v Speaker 1>Think about the physics of it. If a doctor's hand

370
00:18:50.440 --> 00:18:53.359
<v Speaker 1>can feel the physical tactile resistance of a scalpel one

371
00:18:53.359 --> 00:18:57.240
<v Speaker 1>thousand miles away, and their brain registers that physical sensation

372
00:18:57.400 --> 00:19:00.759
<v Speaker 1>is happening instantaneously in their own hand. Where does the

373
00:19:00.839 --> 00:19:03.839
<v Speaker 1>human end and the net work begin? Thank you for

375
00:19:06.799 --> 00:19:07.880
<v Speaker 1>networks all around you.
