00:00:00,820 --> 00:00:06,700
After the ChirpStack Network Server installation, we will see a second LoRaWAN server called the Things
1

2
00:00:06,700 --> 00:00:07,300
Stack.
2

3
00:00:07,480 --> 00:00:10,750
It's exactly the one we've used at the beginning of this course.
3

4
00:00:10,780 --> 00:00:14,350
When we use The Things Network, we use The Things Stack.
4

5
00:00:14,650 --> 00:00:19,660
Actually, there are many versions of The Things Stack, but they all use the same software.
5

6
00:00:20,140 --> 00:00:23,230
The Things Stack Community is the one we've used.
6

7
00:00:23,260 --> 00:00:26,440
The common name for this edition is the Thing Network.
7

8
00:00:26,650 --> 00:00:29,630
The Things Stack Cloud is the commercial edition.
8

9
00:00:29,650 --> 00:00:36,700
Of course you will have to pay subscription fees to use it, but if we want we can install The Things
9

10
00:00:36,700 --> 00:00:38,920
Stack on our own server for free.
10

11
00:00:39,040 --> 00:00:42,460
This is called The Things Stack Open Source.
11

12
00:00:42,580 --> 00:00:48,880
All these editions are actually based on the same open source software and the source code is available
12

13
00:00:48,910 --> 00:00:49,690
on GitHub.
13

14
00:00:50,020 --> 00:00:57,460
But like all Lorawan architecture, there will be a Network Server for authentication and an Application
14

15
00:00:57,460 --> 00:00:58,960
Server for the encryption.
15

16
00:00:59,140 --> 00:01:02,810
We've seen this architecture many times already in this course.
16

17
00:01:03,080 --> 00:01:09,650
When we installed ChirpStack in the previous video, we saw a new service in front of the Network Server
17

18
00:01:09,650 --> 00:01:11,630
called Gateway Bridge.
18

19
00:01:11,870 --> 00:01:17,930
We have exactly the same service in The Things Stack, but here it's called Gateway Server.
19

20
00:01:18,470 --> 00:01:25,370
You can go to the previous video to understand the role of this service, but if you want a little reminder,
20

21
00:01:25,400 --> 00:01:31,190
we just need to know that the gateway server is here to keep alive the communication with gateways.
21

22
00:01:31,640 --> 00:01:38,630
So the gateway server knows all packets forwarder used by The Things Stack. On the other side, the Network
22

23
00:01:38,630 --> 00:01:41,300
Server will only focus on the loRaWAN stack.
23

24
00:01:41,750 --> 00:01:48,590
Finally, on the right we have multiple interfaces with the Iot platforms and user applications.
24

25
00:01:48,860 --> 00:01:54,530
In The Things Stack we'll one more time find the MQTT or HTTP protocols.
25

26
00:01:55,220 --> 00:02:01,580
Okay, so now in the next video we'll see how to install The Things Stack on our own server.
