“How Does Bluetooth Work” Full Case Study !

How the devices like speaker , earphones etc work ! What is the magic behind the Bluetooth tech . So in this blog we will be discussing about how does Bluetooth work in full detail .

The idea of Bluetooth was first introduced in the year 1989 . Because cords and wires are annoying . It was a major undertaking , So many engineers were called up .

Dr. Jaap Haartsen after 5 years who made the breakthrough and came out with the first protocol . It took a few more years to perfect the technology .

But finally in 1999, they presented their first hands free headset to the world at the Comdex computer exposition and trade show in Las Vegas .

It even won the best of the show Award ! So after all that this technology was named as ‘BLUETOOTH ‘ . How does the strange name of this technology come from ?

AT the time , three companies were working separately to create short-range-radio technologies that will connect computer and different devices using short-wave frequencies .

Because the invention was in the early stages , Intel , Ericsson , and Nokia decided that the best way to proceed was to create a single wireless standard.

Jim kardach , who was working for intel , and was reading a historical book about how the viking king harald “Bluetooth” Gormsson united denmark and norway

That story inspired kardach to propose his idea of calling this single short-link device that will unite communications “BLUETOOTH” So that was it .

HOW DOES IT WORK ?

Bluetooth works lot like Wi-Fi. It uses radio waves to send data between devices at short distances . Now , whereas Wi-Fi uses radio waves to transmit data between your router .

Bluetooth does it between devices , So basically it two things have Bluetooth option then they can transmit data between each other.

This communication of sorts in measured in Gigahertz. For both Bluetooth and WiFi it’s usually at the 2.4 Gigahertz frequency .

That means those radio waves are moving hoards and at very fast speed . Which is 2.4 billion waves per second !

That’s why when you , say , turn your Bluetooth mouse on , the Cursor starts whipping around . Now , ever though Bluetooth still works at the 2.4 Ghz freq. just like WiFI .

Bluetooth can only work at shorten distances and uses much weaker signals as compared to wifi . It is about i milliwatt of power.

You know those little laser pointers with which you used to play when you were a kid . They put out 5 milliwatts of power so that goes to show you how weak just 1 is .

Bluetooth does not need as much power as Wifi needs because it’s not really doing as much work . But the most coolest thing is that Bluetooth can connect upto 8 devices at the same time without any interference from other wireless items like garage doors or baby monitors.

When you try to connect a Bluetooth device with your phone then a sort of conversation takes place between two devices.

They present their data and decide on whether they need to exchange information or if one of them needs to control the other .

After the digital dialogue ends and the two devices agree their roles, they connect together to form a network .

That Bluetooth network of connected devices is called a “piconet”. Once their connection is established they begin their frequency hopping in order to continually stay connected and avoid interface.

You can even take the that device to the other rook and it will keep working . As long as you do not go too far form it’s range.

Bluetooth has become a huge part of our daily lives and the most of the time it goes unnoticed . So if you think that what devices use Bluetooth nowadays , the answer is almost all of them .

Phones , headphones , earbuds , speakers , stereos , tv , cars , tablets , cameras , game controllers ,etc .

So that’s it i hope you now that “How Does Bluetooth Work” If you are having any question regarding this article you are free to comment below.
