00:00:00,840 --> 00:00:04,890
In this part, we're going to handle a complete lorawan network configuration.
1

2
00:00:05,220 --> 00:00:09,690
But to do that, we first need to have an operational network available.
2

3
00:00:10,200 --> 00:00:13,320
So maybe you have a private network in operation.
3

4
00:00:13,650 --> 00:00:16,860
It's not the most common situation when you start playing with Lorawan.
4

5
00:00:16,860 --> 00:00:23,340
But anyway, if it's your situation, then your gateway must be connected to internet and you must have
5

6
00:00:23,340 --> 00:00:25,290
set up the LoRaWAN server yourself.
6

7
00:00:25,800 --> 00:00:31,980
If you choose a hybrid network infrastructure, then your gateway must be also connected to internet and
7

8
00:00:31,980 --> 00:00:34,620
you must have subscribed to a LoRaWAN provider.
8

9
00:00:34,710 --> 00:00:37,260
It can be, for example, a community network.
9

10
00:00:37,260 --> 00:00:43,320
Community network are often a nice solution when you start, because if you don't have a gateway, you can
10

11
00:00:43,320 --> 00:00:46,050
even rely on the community onces available.
11

12
00:00:46,080 --> 00:00:52,230
But be careful because depending on the area you're staying, there is not necessarily a coverage with
12

13
00:00:52,230 --> 00:00:56,580
the community Gateway registered, so please check it before starting.
13

14
00:00:56,940 --> 00:01:03,060
Then finally, if you don't want to deploy anything but you end-device, then for a few euros you can
14

15
00:01:03,060 --> 00:01:04,830
subscribe to a public network.
15

16
00:01:04,860 --> 00:01:10,980
The coverage with public network is usually quite good, but again, please check it on the public operator
16

17
00:01:10,980 --> 00:01:11,760
website.
17

18
00:01:12,390 --> 00:01:19,170
Okay, so the nice thing now is that from this point we will only have a four steps configuration to
18

19
00:01:19,170 --> 00:01:20,460
make everything work.
19

20
00:01:20,610 --> 00:01:26,130
And if you choose someone else gateway, in the case of community network or public network, then
20

21
00:01:26,130 --> 00:01:28,740
they will be only two steps to carry out.
21

22
00:01:29,010 --> 00:01:30,300
So let's start.
22

23
00:01:32,030 --> 00:01:34,430
The first step is the gateway configuration.
23

24
00:01:34,610 --> 00:01:41,030
This configuration will allow the gateway to be aware of the targeting network server and also the protocol
24

25
00:01:41,030 --> 00:01:41,720
used.
25

26
00:01:41,750 --> 00:01:47,720
Unfortunately, Lorawan doesn't specify one protocol between the gateway and the network server.
26

27
00:01:48,170 --> 00:01:52,790
So many LoRaWAN players have developed their own solution.
27

28
00:01:53,570 --> 00:02:00,590
The protocol use between the gateway and the network server is handled by what we call a packet forwarder.
28

29
00:02:01,010 --> 00:02:07,190
So when you hear about a packet forwarder software just think about a small piece of software installed
29

30
00:02:07,190 --> 00:02:13,670
on the gateway in order to communicate to the network server the most commonly used protocol is the old
30

31
00:02:13,670 --> 00:02:20,300
Semtech packet forwarder. I said old because this protocol was the first packet forwarder created a long
31

32
00:02:20,300 --> 00:02:20,960
time ago.
32

33
00:02:20,990 --> 00:02:25,010
The funny thing is that it was not originally supposed to last that much.
33

34
00:02:25,280 --> 00:02:31,550
It has only a few functionalities, but it's still a very common packet forwarder nowadays because it's
34

35
00:02:31,550 --> 00:02:32,480
very simple.
35

36
00:02:32,510 --> 00:02:39,870
You will also probably hear about LoRa basic station also created by Semtech and LRR by Actility
36

37
00:02:40,010 --> 00:02:40,390
.
37

38
00:02:40,400 --> 00:02:45,920
Loriot your packet forwarder, for Loriot network and so on. But be careful,
38

39
00:02:45,950 --> 00:02:49,040
Network servers don't support all packet forwarders.
39

40
00:02:49,040 --> 00:02:54,500
So before choosing a packet forwarder for your gateway, you need to check if it's supported on the
40

41
00:02:54,500 --> 00:02:55,910
network server side.
41

42
00:02:56,630 --> 00:03:02,600
OK, and once you have your packet forwarder ready, then its configuration is very easy.
42

43
00:03:02,990 --> 00:03:09,860
You just enter the network server IP address as well as the UDP or TCP port of the protocol used.
43

44
00:03:09,950 --> 00:03:15,170
And if you have a secure transmission, you will also have to provide a private keys and certificate
44

45
00:03:15,170 --> 00:03:16,190
for the connection.
45

46
00:03:17,440 --> 00:03:21,040
The second step is the gateway registration on the network server.
46

47
00:03:21,340 --> 00:03:21,910
We'll see 
47

48
00:03:21,910 --> 00:03:23,560
that's a pretty easy task.
48

49
00:03:23,590 --> 00:03:27,880
It basically says that this gateway is allowed to talk to the server.
49

50
00:03:28,480 --> 00:03:33,730
Next, for the third step, we're going to register our device on the network server.
50

51
00:03:33,940 --> 00:03:36,610
You can register thousands of devices.
51

52
00:03:36,640 --> 00:03:42,760
Each of them will have a particular configuration and we'll enter the LoRaWAN parameters depending
52

53
00:03:42,760 --> 00:03:43,990
on the activation mode,
53

54
00:03:43,990 --> 00:03:47,230
we want to use ABP or OTAA.
54

55
00:03:47,530 --> 00:03:53,290
Sometimes on network server there is a possibility to organize devices by groups.
55

56
00:03:53,440 --> 00:04:00,850
The groups are created to gather devices of the same use case, and these groups are often called applications.
56

57
00:04:01,390 --> 00:04:07,270
You can just consider an application as a folder or a box in which you store your devices.
57

58
00:04:08,350 --> 00:04:12,520
And finally, the fourth step is the device configuration.
58

59
00:04:12,550 --> 00:04:17,620
This is done on the device itself by programming a new firmware to enter the LoRaWAN.
59

60
00:04:17,620 --> 00:04:22,840
Parameters will see both activation methods, ABP and OTAA.
60

61
00:04:23,140 --> 00:04:24,820
So let's get started.
