Bluetooth is actually nothing to do with teeth It's a wireless Technology
0:07
standard for exchanging data over short distances using short wavelength UHF
0:13
radio Waves bluetooth transmits in the ism That's for Industrial Scientific
0:17
Medical Devices band from 2402 to 283.5
0:22
MHz also known as the 2.4 GHz short
0:25
range radio frequency band including ITS guard bands and as Such It's also
0:32
so The Story Behind The Name then The Original standard was developed by the
0:36
Telecom vendor ericson in 1994 as a
0:39
wireless alternative to rs232 data
0:43
cables It didn't receive The Name Bluetooth until 1997 When Jim kardak Who
0:48
developed a Communication System between mobile phones and computers proposed it while reading the long ships by France
1:18
between two to eight devices where there is one Master device
1:23
and up to seven slave Devices Vikings am
1:26
I Right and while It was only intended to replace serial Cable it can do so
1:31
much more You can wirelessly control and communicate between a mobile phone or
1:36
tablet and handsfree headset car audio System speaker System and Intercom You
1:41
can network with a pc so like transfer files You can control printers and
1:45
computer peripherals barcode scanners and Traffic control Devices and even
1:49
replace infrared scanning in some cases and that list is not exhaustive by any
1:53
means so Ok it does lots of stuff but How does it it work Well there are two main
1:58
components at the physical level Well Works Pretty much the same Way as any
2:02
other radio frequency standard with antennas that can broadcast and receive
2:05
signals in the appropriate bands but at the protocol level Things Get a little
2:10
bit different to achieve a robust enough
2:13
connection for Communication use even in environments with very Heavy
2:17
interference Bluetooth communicates with very short transmission bursts and then
2:22
quickly does microps Around to the
2:25
various frequencies Within ITS range and it allows More than One device to
2:30
transmit on the same frequency at the same time but Constant transmission of
2:36
data means higher power consumption and for Years most Bluetooth Devices
2:41
suffered from Lame dock Battery Life that pained users and Made the standard
2:46
not practical for many Applications until a few Years ago Bluetooth 4.0 or
2:52
Bluetooth Smart Came on the Scene it's basically the power efficient version of
2:56
Bluetooth that has enabled Amazing stuff like Devices with with One To two Years
3:01
Of Battery Life On A single button cell I mean I wish My Phone could do that
3:05
It's to Bad Has to Power other stuff like the screen the one Issue with
3:08
Bluetooth Smart accessories is that They Can Only be Used with Bluetooth Smart
3:13
Ready Primary Devices smartphones notebooks tablets a qualification Given
3:18
to phones that are by definition compatible with Bluetooth Smart
3:22
accessories meaning that There is no backwards compatibility between phones
3:26
with older versions of Bluetooth like 2.0 or 3.
3:30
and Devices that are equipped with Bluetooth Smart Bluetooth Smart Ready
3:34
Primary Devices however are backwards compatible with accessories that Run
3:38
older versions of Bluetooth One other Cool Bluetooth 4.0 fact is that range
3:43
Just no longer Locked down so while manufacturers can OPT to optim for more
3:47
traditional 10 Meter or 30 m ranges It's possible for Devices to work at 60 m or
3:54
Beyond so That's it Bluetooth is a Low Speed interference resistant commun
4:00
protocol that allows Devices to transfer data across multiple platforms at short
4:05
range and now with Great efficiency speaking of efficiency what If There Was
4:09
some way that We could read Books while doing other Things like Driving Working
4:15
or even cleaning ourselves in the shower seriously shower speakers exist by the
