Congratulations.

2
00:00:01,890 --> 00:00:03,490
We've seen a lot of things so far.
2

3
00:00:03,510 --> 00:00:04,410
So let's recap.
3

4
00:00:05,280 --> 00:00:11,340
First of all, we saw in the first video that the LoRa modulation is a long distance and a low speed transmission.
4

5
00:00:12,090 --> 00:00:17,100
By the way, the word long distance come from its name because LoRa stands for Long Range.
5

6
00:00:18,150 --> 00:00:23,970
Then we saw that if we use LoRaWAN in Europe it transmits on channels belonging to
6

7
00:00:23,970 --> 00:00:31,320
the 868 MHz band. And several end devices can transmit at the same time and on the same channel,
7

8
00:00:31,800 --> 00:00:38,310
if each of them uses a different parameter called spreading factor. This spreading factor can be from
8

9
00:00:38,310 --> 00:00:40,320
SF5 up to SF12.
9

10
00:00:41,130 --> 00:00:47,670
If we use LoRaWAN, which will be the case in this lecture, there are only 6 spreading factors from SF7
10

11
00:00:47,670 --> 00:00:49,200
to SF12.
11

12
00:00:50,340 --> 00:00:53,940
I sometimes use the word LoRa and sometimes LoRaWAN.
12

13
00:00:54,630 --> 00:00:55,640
But no worries,
13

14
00:00:55,650 --> 00:01:00,810
there will be a dedicated video to explain the differences between the modulation and the protocol.
14

15
00:01:01,890 --> 00:01:05,520
However, we will mainly speak about LoRaWAN later in this course.
15

16
00:01:06,450 --> 00:01:12,060
So now in the next chapter, we are going to see what kind of performances we can expect for wireless
16

17
00:01:12,060 --> 00:01:18,210
radio transmission and what terms we need to master to be comfortable with a technical documentation
17

18
00:01:18,210 --> 00:01:19,890
about a LoRa end device.
