00:00:00,950 --> 00:00:06,140
The first step of the LoRaWAN Network configuration is the Gateway configuration.
1

2
00:00:06,320 --> 00:00:12,590
This will allow the Gateway to be aware of the targeted Network Server and also the protocol used.
2

3
00:00:12,950 --> 00:00:19,760
We saw previously that unfortunately LoRaWAN doesn't specify one protocol between the gateway and the
3

4
00:00:19,760 --> 00:00:20,540
Network Server.
4

5
00:00:20,930 --> 00:00:25,220
So, many LoRaWAN players have developed their own solutions.
5

6
00:00:25,790 --> 00:00:32,030
The protocol used between the Gateway and the Network Server is handled by what we call a packet forwarder.
6

7
00:00:32,840 --> 00:00:39,260
The most commonly used protocol is UDP SEMTECH packet forwarder, but there are many others like
7

8
00:00:39,260 --> 00:00:41,990
LoRa Basic Station, also created by Semtech,
8

9
00:00:42,190 --> 00:00:44,300
LRR created by Actility,
9

10
00:00:44,330 --> 00:00:48,410
LORIOT packet forwarder uses for LORIOT Network Server and so on.
10

11
00:00:49,010 --> 00:00:53,480
The problem is that all Network Servers don't support all packet forwarders.
11

12
00:00:53,660 --> 00:00:59,300
Fortunately, most Gateways support several packet forwarders, so in that case you're pretty sure that
12

13
00:00:59,300 --> 00:01:02,190
at least one will be compatible with the Network Server.
13

14
00:01:03,120 --> 00:01:08,980
So, before choosing a Gateway with its packet forwarder, we need to check on the Network Server documentation
14

15
00:01:09,000 --> 00:01:15,780
the compatibilities they offer. At the time we posted this video, Chirpstack and The Things Stack can both support
15

16
00:01:15,780 --> 00:01:23,820
Semtech UDP packet forwarder and Basic Station packet forwarder. And in our case, for our private network
16

17
00:01:23,820 --> 00:01:27,300
configuration, we will use Semtech UDP packet forwarder.
17

18
00:01:27,300 --> 00:01:29,850
So, everything should work with both Network Servers.
