00:00:00,350 --> 00:00:04,680
The LoRaWAN network we've worked so far was a hybrid network.
1

2
00:00:04,730 --> 00:00:08,510
We've used it for all demonstrations since the beginning of this course.
2

3
00:00:08,630 --> 00:00:14,960
In a previous video, we already explained what a hybrid network is, but we can briefly remind it.
3

4
00:00:15,230 --> 00:00:21,620
It's when we use our own Gateway, but with a LoRaWAN server that doesn't belong to us.
4

5
00:00:21,950 --> 00:00:25,790
In our case, we mostly use TTN as a Network Server.
5

6
00:00:25,820 --> 00:00:30,170
But, there were also some demonstrations with Loriot or Actility.
6

7
00:00:30,800 --> 00:00:34,480
Anyway, none of these are managed by our organization.
7

8
00:00:34,490 --> 00:00:40,940
It wasn't set up on our premises, and we didn't have to care about the server administration and its
8

9
00:00:40,940 --> 00:00:42,020
availability.
9

10
00:00:42,290 --> 00:00:49,190
What we want now is to do the installation of our own Network Server and our own Application Server.
10

11
00:00:49,640 --> 00:00:55,670
If we set up such a network, we'll have the full control of every part of the LoRaWAN transmission.
11

12
00:00:55,940 --> 00:00:58,370
We'll have our own End-device.
12

13
00:00:58,400 --> 00:01:04,820
We'll have our own Gateways and finally our own Network Server and Application Server.
13

14
00:01:05,390 --> 00:01:11,390
And that's exactly the definition of a private network, since all entities will belong to us.
14

15
00:01:11,930 --> 00:01:18,860
In some situations, having a private LoRaWAN network can indeed be a really good choice because
15

16
00:01:18,860 --> 00:01:24,740
even if it requires a lot of effort to build it, we will end up with a complete confidential network with
16

17
00:01:24,740 --> 00:01:27,500
no data transferred on public infrastructure.
17

18
00:01:28,130 --> 00:01:30,950
Besides, we'll administrate our server,
18

19
00:01:31,340 --> 00:01:35,720
that means that we can scale its capability as much as we want.
19

20
00:01:36,230 --> 00:01:43,760
We can also be especially careful of its availability and on top of that, with a private network,
20

21
00:01:43,760 --> 00:01:49,070
we don't need to pay any subscription fee to a provider, as it's the case with a hybrid network or
21

22
00:01:49,070 --> 00:01:50,390
a public network.
22

23
00:01:50,900 --> 00:01:56,570
So, for all these reasons, it can be interesting to set up a Network Server and Application Server
23

24
00:01:56,570 --> 00:01:57,650
by yourself.
24

25
00:01:57,830 --> 00:02:04,440
And apart from installing the server as we'll see in the next video, the only other configuration we'll
25

26
00:02:04,440 --> 00:02:07,740
have to do is to modify the Gateway parameters.
26

27
00:02:07,980 --> 00:02:12,720
Because from now on, our Gateway will have to point to the new network server.
27

28
00:02:12,750 --> 00:02:18,210
Whereas before they forwarded the message to TTN, Actility or Loriot Network Server.
28

29
00:02:19,230 --> 00:02:25,800
In the next videos, we'll present and explain in detail the installation and configuration of two LoRaWAN 
29

30
00:02:25,800 --> 00:02:26,610
servers.
30

31
00:02:26,820 --> 00:02:28,470
First, we'll use Chirpstack.
31

32
00:02:28,470 --> 00:02:29,160
...
32

33
00:02:29,190 --> 00:02:35,790
Chirpstack is a project led by Orne Brocaar. He is the initial author and the main contributor of this LoRaWAN 
33

34
00:02:35,790 --> 00:02:36,270
server.
34

35
00:02:36,900 --> 00:02:40,440
Then, after we will try The Things Stack.
35

36
00:02:40,470 --> 00:02:46,380
The Things Stack is the one used by the community network called The Things Network, so it's the same
36

37
00:02:46,380 --> 00:02:48,420
one we use in our demonstrations.
37

38
00:02:48,540 --> 00:02:52,980
But of course this time it will be installed on our own server.
38

39
00:02:53,250 --> 00:02:58,980
This Lorawan server is supported by The Things Industry, a big player in the LoRaWAN ecosystem.
39

40
00:02:59,400 --> 00:03:05,340
Both are free, both are open source and they both have a strong and reliable community.
40

41
00:03:05,370 --> 00:03:10,680
You will see that it's very comfortable to rely on a solid community of developers, professionals and
41

42
00:03:10,680 --> 00:03:11,370
hobbyists.
42

43
00:03:11,370 --> 00:03:17,190
But of course for both of them you can also have a commercial support. As a company,
43

44
00:03:17,190 --> 00:03:22,290
if you're stuck with a configuration or if you need a special development, then you can contact them
44

45
00:03:22,290 --> 00:03:23,310
for support.
45

46
00:03:23,970 --> 00:03:29,460
Okay, so before starting the server installation, we need to speak about two things.
46

47
00:03:29,910 --> 00:03:35,820
First, we need to speak of the Gateway configuration, because even if most Gateway are compatible
47

48
00:03:35,820 --> 00:03:39,240
with all network servers, there might be some exceptions.
48

49
00:03:39,240 --> 00:03:41,850
So, I just want to check that before we start.
49

50
00:03:42,480 --> 00:03:47,430
And secondly, in another video, I want to present the different solutions
50

51
00:03:47,430 --> 00:03:49,140
we have to set up the Network Server.
51

52
00:03:49,260 --> 00:03:56,250
There are many possibilities, including using our own computer, but some options are easier to set up.
52

53
00:03:56,250 --> 00:03:56,670
...
53

54
00:03:57,300 --> 00:04:03,030
Anyway, we'll go through all the possibilities and I'm sure there will be at least one which will suit
54

55
00:04:03,030 --> 00:04:03,480
you.
