1
00:00:03,400 --> 00:00:10,040
Bluetooth is actually nothing to do with teeth It's a wireless Technology

2
00:00:07,839 --> 00:00:15,400
standard for exchanging data over short distances using short wavelength UHF

3
00:00:13,040 --> 00:00:22,240
radio Waves bluetooth transmits in the ism That's for Industrial Scientific

4
00:00:17,840 --> 00:00:25,279
Medical Devices band from 2402 to 283.5

5
00:00:22,240 --> 00:00:27,640
MHz also known as the 2.4 GHz short

6
00:00:25,279 --> 00:00:31,960
range radio frequency band including ITS guard bands and as Such It's also

7
00:00:32,200 --> 00:00:39,960
so The Story Behind The Name then The Original standard was developed by the

8
00:00:36,399 --> 00:00:43,000
Telecom vendor ericson in 1994 as a

9
00:00:39,960 --> 00:00:44,960
wireless alternative to rs232 data

10
00:00:43,000 --> 00:00:50,920
cables It didn't receive The Name Bluetooth until 1997 When Jim kardak Who

11
00:00:48,920 --> 00:00:53,280
developed a Communication System between mobile phones and computers proposed it while reading the long ships by France

12
00:01:18,600 --> 00:01:26,320
between two to eight devices where there is one Master device

13
00:01:23,280 --> 00:01:28,560
and up to seven slave Devices Vikings am

14
00:01:26,320 --> 00:01:34,000
I Right and while It was only intended to replace serial Cable it can do so

15
00:01:31,240 --> 00:01:38,520
much more You can wirelessly control and communicate between a mobile phone or

16
00:01:36,320 --> 00:01:43,439
tablet and handsfree headset car audio System speaker System and Intercom You

17
00:01:41,040 --> 00:01:47,520
can network with a pc so like transfer files You can control printers and

18
00:01:45,159 --> 00:01:52,119
computer peripherals barcode scanners and Traffic control Devices and even

19
00:01:49,799 --> 00:01:56,200
replace infrared scanning in some cases and that list is not exhaustive by any

20
00:01:53,960 --> 00:02:01,000
means so Ok it does lots of stuff but How does it it work Well there are two main

21
00:01:58,159 --> 00:02:04,079
components at the physical level Well Works Pretty much the same Way as any

22
00:02:02,479 --> 00:02:08,200
other radio frequency standard with antennas that can broadcast and receive

23
00:02:05,920 --> 00:02:13,080
signals in the appropriate bands but at the protocol level Things Get a little

24
00:02:10,080 --> 00:02:15,560
bit different to achieve a robust enough

25
00:02:13,080 --> 00:02:19,840
connection for Communication use even in environments with very Heavy

26
00:02:17,360 --> 00:02:25,280
interference Bluetooth communicates with very short transmission bursts and then

27
00:02:22,280 --> 00:02:28,080
quickly does microps Around to the

28
00:02:25,280 --> 00:02:32,239
various frequencies Within ITS range and it allows More than One device to

29
00:02:30,080 --> 00:02:38,879
transmit on the same frequency at the same time but Constant transmission of

30
00:02:36,120 --> 00:02:43,200
data means higher power consumption and for Years most Bluetooth Devices

31
00:02:41,120 --> 00:02:48,599
suffered from Lame dock Battery Life that pained users and Made the standard

32
00:02:46,280 --> 00:02:54,519
not practical for many Applications until a few Years ago Bluetooth 4.0 or

33
00:02:52,000 --> 00:02:59,000
Bluetooth Smart Came on the Scene it's basically the power efficient version of

34
00:02:56,720 --> 00:03:04,120
Bluetooth that has enabled Amazing stuff like Devices with with One To two Years

35
00:03:01,560 --> 00:03:06,760
Of Battery Life On A single button cell I mean I wish My Phone could do that

36
00:03:05,280 --> 00:03:10,879
It's to Bad Has to Power other stuff like the screen the one Issue with

37
00:03:08,799 --> 00:03:15,440
Bluetooth Smart accessories is that They Can Only be Used with Bluetooth Smart

38
00:03:13,400 --> 00:03:20,319
Ready Primary Devices smartphones notebooks tablets a qualification Given

39
00:03:18,319 --> 00:03:24,280
to phones that are by definition compatible with Bluetooth Smart

40
00:03:22,000 --> 00:03:28,360
accessories meaning that There is no backwards compatibility between phones

41
00:03:26,480 --> 00:03:31,760
with older versions of Bluetooth like 2.0 or 3.

42
00:03:30,239 --> 00:03:36,239
and Devices that are equipped with Bluetooth Smart Bluetooth Smart Ready

43
00:03:34,200 --> 00:03:41,080
Primary Devices however are backwards compatible with accessories that Run

44
00:03:38,439 --> 00:03:45,239
older versions of Bluetooth One other Cool Bluetooth 4.0 fact is that range

45
00:03:43,640 --> 00:03:50,480
Just no longer Locked down so while manufacturers can OPT to optim for more

46
00:03:47,879 --> 00:03:57,079
traditional 10 Meter or 30 m ranges It's possible for Devices to work at 60 m or

47
00:03:54,120 --> 00:04:01,959
Beyond so That's it Bluetooth is a Low Speed ​​interference resistant commun

48
00:04:00,079 --> 00:04:07,360
protocol that allows Devices to transfer data across multiple platforms at short

49
00:04:05,040 --> 00:04:12,840
range and now with Great efficiency speaking of efficiency what If There Was

50
00:04:09,959 --> 00:04:18,000
some way that We could read Books while doing other Things like Driving Working

51
00:04:15,159 --> 00:04:22,160
or even cleaning ourselves in the shower seriously shower speakers exist by the
