1
00:00:01,810 --> 00:00:07,750
So now we are going to find the frequency of devices which don't have FCC ID mentioned.

2
00:00:08,740 --> 00:00:12,160
So all you have to do is you just have to Google those devices.

3
00:00:12,550 --> 00:00:17,380
So let's just say, let's just start with wireless doorbell, so let's just type.

4
00:00:19,050 --> 00:00:21,690
Wireless doorbell frequency.

5
00:00:24,590 --> 00:00:29,510
And you will get a rough frequency around 400 to 500 megahertz.

6
00:00:29,810 --> 00:00:37,190
So this is a rough frequency and you have to find the exact frequency in between these frequencies.

7
00:00:37,520 --> 00:00:37,820
Right.

8
00:00:38,060 --> 00:00:41,240
So we will see how we can find the exact frequency in a moment.

9
00:00:41,690 --> 00:00:48,650
So any wireless device which you have like wireless switch or wireless doorbell, you can just search

10
00:00:48,650 --> 00:00:54,530
for the frequency and you will get a rough frequency around whatever the frequency is right?

11
00:00:54,770 --> 00:01:01,370
So this is the frequency of wireless doorbell pro frequency of wireless doorbell.

12
00:01:01,820 --> 00:01:04,360
So let's just start digging out.

13
00:01:05,180 --> 00:01:10,010
So let me first connect my head got a fun device with Dragon with.

14
00:01:15,100 --> 00:01:20,920
So Hack got one device is connected now, and let's just do.

15
00:01:22,840 --> 00:01:23,730
GQ Ortex.

16
00:01:26,560 --> 00:01:27,730
And let's just.

17
00:01:29,410 --> 00:01:30,910
Connect are have got it fun.

18
00:01:31,300 --> 00:01:37,680
So over here, you can see, so all you have to do is you just have to you just have to click or hit

19
00:01:37,680 --> 00:01:42,100
and configure your devices option and you will see a different option.

20
00:01:42,610 --> 00:01:44,680
So you have to select had got if one.

21
00:01:46,300 --> 00:01:52,540
And let's just do OK, and let's just start with four hundred megahertz.

22
00:01:55,420 --> 00:01:58,660
And let me press the button off my wireless doorbell.

23
00:02:04,130 --> 00:02:10,250
So you can hear the sound of a bell in the background, so I just pressed my button.

24
00:02:10,760 --> 00:02:15,530
But we cannot see any change on the graph or on the waterfall or here.

25
00:02:16,520 --> 00:02:19,210
So let's just change the frequency a bit.

26
00:02:19,250 --> 00:02:23,350
Let's just go on for 10, and let's just press one more time.

27
00:02:28,020 --> 00:02:29,250
Still, there is no change.

28
00:02:29,550 --> 00:02:31,530
Let's just try on for 20.

29
00:02:36,380 --> 00:02:37,370
Still no change.

30
00:02:37,610 --> 00:02:39,350
Let's just try on for 30.

31
00:02:46,910 --> 00:02:48,110
Let me try it one more time.

32
00:02:50,870 --> 00:02:51,740
There is no change.

33
00:02:52,010 --> 00:02:53,810
Let's just try on for thirty one.

34
00:02:57,670 --> 00:03:03,130
Still, no change for 32, no change.

35
00:03:03,160 --> 00:03:04,840
Let's just drown for 33.

36
00:03:08,870 --> 00:03:12,170
So we are getting some data out here.

37
00:03:14,300 --> 00:03:15,080
Here, you can see,

38
00:03:18,890 --> 00:03:20,750
but the peak is not that strong.

39
00:03:21,320 --> 00:03:22,250
So let's just.

40
00:03:27,300 --> 00:03:29,340
That's just right on 3:45.

41
00:03:35,280 --> 00:03:39,110
And what are you going to see a big magnitude one more day?

42
00:03:40,950 --> 00:03:43,020
So we are getting a good peak would here.

43
00:03:45,890 --> 00:03:46,730
That's just like.

44
00:03:56,140 --> 00:04:01,780
So the frequency is around for thirty three point nine zero one point one zero zero.

45
00:04:02,530 --> 00:04:02,800
Right.

46
00:04:02,950 --> 00:04:06,160
So this is a frequency of wireless doorbell.

47
00:04:06,970 --> 00:04:08,610
We can load down this frequency.

48
00:04:08,620 --> 00:04:14,320
It will help us in our future videos when we will do our transmitter attack or replay attack.

49
00:04:14,650 --> 00:04:16,810
So we have to use the very same frequency.

50
00:04:17,140 --> 00:04:19,420
So let me give you a rough idea.

51
00:04:19,870 --> 00:04:27,250
Almost all of these devices, this wireless doorbells and wireless switches lie around for three to

52
00:04:27,250 --> 00:04:28,840
450 megahertz.

53
00:04:28,990 --> 00:04:31,230
This is my personal experience, right?

54
00:04:31,540 --> 00:04:34,030
It could be different on different parts of the world.

55
00:04:34,720 --> 00:04:42,340
But on my experience, most of the devices lie between 433 for 30 44 50 megahertz.

56
00:04:42,610 --> 00:04:49,960
So around you can just set a window of four from four 30 megahertz to 450 megahertz.

57
00:04:50,140 --> 00:04:54,910
First, check the frequency on this window from 430 to 450 megahertz.

58
00:04:55,150 --> 00:05:02,050
And if you don't find the frequency in this window, then you can change the frequency from 400 to 500

59
00:05:02,050 --> 00:05:02,440
megahertz.

60
00:05:02,680 --> 00:05:04,720
So this is my personal experience.

61
00:05:05,200 --> 00:05:10,120
Usually, these devices almost start from 433 to 450.

62
00:05:10,390 --> 00:05:12,580
So what here you can see again one more time.

63
00:05:15,710 --> 00:05:19,850
So it's for thirty three point nine zero one point one zero zero.

64
00:05:20,030 --> 00:05:25,700
So this is the frequency of our wireless broadband and the next video, we are going to see how we can

65
00:05:25,700 --> 00:05:29,360
find the frequency of wireless switch using the same method.
