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