1 00:00:00,000 --> 00:00:19,920 The mesh network allows you to connect each of the laptops together without having to 2 00:00:19,920 --> 00:00:25,760 have a server in between, and this sort of frees them up to talk to each other without 3 00:00:25,760 --> 00:00:30,080 having to have complex hardware or expensive hardware. 4 00:00:30,080 --> 00:00:36,660 Okay, it's a wireless network, but it's different from your normal wireless network in the sense 5 00:00:36,660 --> 00:00:42,520 that every node, that is, every computer, can also route the traffic from other computers 6 00:00:42,520 --> 00:00:47,040 to get to an access point or a mesh portal in this case. 7 00:00:47,040 --> 00:00:52,800 My name is Miguel Angel Alvarez, and I'm an engineer here at the OLC. 8 00:00:52,800 --> 00:01:00,640 Usually you have one access point in the middle, and everyone will connect directly to the 9 00:01:00,640 --> 00:01:01,640 access point. 10 00:01:01,640 --> 00:01:06,640 And when you have a mesh network, you can have another one farther off, who connects 11 00:01:06,640 --> 00:01:11,480 to the internet or to the access point or to the server through the intermediate node. 12 00:01:11,480 --> 00:01:14,480 Each laptop has a range, and so you can think of it like clouds. 13 00:01:14,480 --> 00:01:19,000 If each laptop has a small cloud around it, when the clouds intersect, they're meshed, 14 00:01:19,320 --> 00:01:22,760 and you can actually, you know, that makes the entire mesh bigger as you keep adding 15 00:01:22,760 --> 00:01:23,760 more laptops. 16 00:01:23,760 --> 00:01:28,280 And, you know, I mean, this might be, in the case of wireless networking, this might be 17 00:01:28,280 --> 00:01:31,080 300 feet. 18 00:01:31,080 --> 00:01:35,360 Most laptops don't have the ability to dynamically mesh, and so what happens is that if you're 19 00:01:35,360 --> 00:01:41,800 over here, you can't actually access anything, you know, you can't get anywhere. 20 00:01:41,800 --> 00:01:47,080 But with the mesh networking, that actually dynamically extends the range, and so as long 21 00:01:47,080 --> 00:01:53,520 as somebody is between you and the access point of the mesh, you know, which happens 22 00:01:53,520 --> 00:01:57,160 to be school most of the time, then you'll have an internet connection because it can 23 00:01:57,160 --> 00:02:01,200 hop from computer to computer, laptop to laptop to get to the school. 24 00:02:01,200 --> 00:02:06,440 Whether or not there is an internet portal of any kind, the computers can talk to each 25 00:02:06,440 --> 00:02:10,520 other and can collaborate and can execute applications together. 26 00:02:10,520 --> 00:02:15,120 I mean, you can imagine with games that there's a really good possibility to use this because 27 00:02:15,120 --> 00:02:20,440 right now, I mean, there are a lot of network games, but they depend on a server. 28 00:02:20,440 --> 00:02:24,120 And potentially, you know, what you can do is you can just start up a random game and 29 00:02:24,120 --> 00:02:25,200 somebody else can join. 30 00:02:25,200 --> 00:02:27,920 You can invite them to that game, and they can play. 31 00:02:27,920 --> 00:02:31,360 It's really independent of, you know, any of the infrastructure that you might need. 32 00:02:31,360 --> 00:02:34,160 Two kids with laptops sitting under a tree, you could play Kinect 4. 33 00:02:34,160 --> 00:02:37,600 It's a little bit harder in today's computer, and most people don't even think about these 34 00:02:37,600 --> 00:02:40,120 sorts of things when they're making games today. 35 00:02:40,120 --> 00:02:41,920 The hardware is integrated into the main board. 36 00:02:41,920 --> 00:02:48,320 There is a chip which takes care of all network-related stuff, and the antenna, they only serve as 37 00:02:48,320 --> 00:02:53,360 physical gain elements so that you get a little bit better signal-to-noise radio. 38 00:02:53,360 --> 00:02:57,520 The good thing is normally antennas are built behind the screen, and they have some interference 39 00:02:57,520 --> 00:03:00,280 because there is a lot of electric activity going around. 40 00:03:00,280 --> 00:03:04,040 And in this case, we have separated a little bit the antennas from the rest of the computer 41 00:03:04,040 --> 00:03:09,300 so that they are better insulated and they have less noise from other electric components. 42 00:03:09,300 --> 00:03:11,720 And that's beneficial for the whole connection. 43 00:03:11,720 --> 00:03:17,200 Normally, what happens is that there is a mesh view in the interface that shows who 44 00:03:17,200 --> 00:03:21,640 others are present in the mesh network at any given moment. 45 00:03:21,640 --> 00:03:27,840 And in that way, you can either talk to them directly or initiate an activity or share 46 00:03:27,840 --> 00:03:29,520 an activity with them. 47 00:03:29,520 --> 00:03:33,560 And in that way, you can, for example, browse the internet together. 48 00:03:33,560 --> 00:03:37,560 You can both see the same pages and comment what you're seeing, or you can draw a picture 49 00:03:37,560 --> 00:03:38,560 together. 50 00:03:38,560 --> 00:03:44,880 So I downloaded the e-book, Little Women, on this machine, and I shared the activity 51 00:03:44,880 --> 00:03:48,520 by clicking on the share button in the toolbar. 52 00:03:48,520 --> 00:03:52,160 And over on this laptop, it popped up in the mesh view. 53 00:03:52,160 --> 00:03:57,440 So I clicked on it in the mesh view, and that starts up the same instance, a shared instance 54 00:03:57,440 --> 00:04:02,840 of the read activity, which automatically downloads the e-book from this computer to 55 00:04:02,840 --> 00:04:03,840 that computer. 56 00:04:04,000 --> 00:04:08,600 And so both of these laptops right now are reading the e-book, Little Women. 57 00:04:08,600 --> 00:04:12,680 You know, you could highlight things, and that would show up in the other person's document 58 00:04:12,680 --> 00:04:14,800 like, hey, take a look at this. 59 00:04:14,800 --> 00:04:18,400 We also want to do annotations as well, just kind of like leave a little post-it in the 60 00:04:18,400 --> 00:04:20,540 document for the other person as well. 61 00:04:20,540 --> 00:04:27,400 You have to make a mesh which is both more robust and easier to configure, to access, 62 00:04:27,400 --> 00:04:30,880 and to get away from, because the users are going to be children in the end, and they 63 00:04:30,880 --> 00:04:34,920 have to have access to this automatically without having to configure it, without having 64 00:04:34,920 --> 00:04:39,320 to figure out how to connect with one or how to connect with the other, only seeing other 65 00:04:39,320 --> 00:04:41,320 users and being able to interact with them. 66 00:04:41,320 --> 00:04:42,640 And that's one of the things we want. 67 00:04:42,640 --> 00:04:46,880 We don't want them just using the computer so that they can use technology. 68 00:04:46,880 --> 00:04:50,680 We want them to use this computer so that they can become social with each other and 69 00:04:50,680 --> 00:04:51,720 collaborate with each other. 70 00:05:00,880 --> 00:05:01,880 Okay. 71 00:05:01,880 --> 00:05:02,880 Great. 72 00:05:02,880 --> 00:05:02,880
