We all like to listen to music. Over time, the way we access music has evolved with technology. MP3 players, our sound system in cars and evolved into portable speakers. Thankfully, we’ve all said goodbye to those headphone cables that get tangled as soon as we let them go. Of course that Bto luetooth technology we owe

from our computer with the Bluetooth function. we can control multiple devices such as mouse, keyboard and headset at the same time. But how do they determine what kind of connection they have with which device? Let’s take a look at Bluetooth technology and the answers to these questions together.

Bluetooth is a technology based on a system of data transport between two devices using radio waves.

It houses a data transport system just like Wi-Fi; however, while the Wi-Fi system establishes a connection between the router and a device, the Bluetooth technology connection between two devices data transfer is provided. In this system, whose wavelengths are measured in GHz, 2.4 billion waves are emitted every second.

Bluetooth takes its name from the Scandinavian king Harald Bluetooth Gormsson.

“Short Range Radio Technology” Jim Kardach, an employee of Intel, one of the key companies of the period working on the project, and Viking king Harald Bluetooth Gormsson, who united Denmark and Norway in the process. Bluetooth technology is named after a book he read about it. Legend has it that there is a Viking king her color turns blue when she rots.

A Bluetooth enabled device can connect and exchange data with multiple devices without confusion.

Bluetooth is generally used over short distances. and with low signals to the working principle: owner. Each device transmits data between itself and the other device it is connected to, using signals in a different frequency range. between devices during data transfer. a network of signals they form. This is called a piconet. Thanks to this network, the devices do not interfere with the transmission between each other and there is no confusion.

When Bluetooth devices are paired, a meeting takes place like between people.

Any technological device addresses assigned to them by their manufacturers so they have names. Before connecting, they introduce themselves to signal that they are safe from each other. We can compare this to a process where we say our name and introduce ourselves when we meet someone new.

Then they decide how to exchange data between them. On the next data exchange, the two devices can connect without interrogation. because we too We don’t see each other every time we see each other.

The devices switch frequencies 1600 times per minute while establishing a connection with each other.

This one It’s called frequency jumping. Let’s explain with an example: Let’s take a crowded place where everyone is talking loudly to each other. nobody’s we can’t quite understand what you’re talking about but we hear their voices and even perceive a few words. However, if your ears aren’t as good as Legolas’s, we may not be able to decipher what the conversation is about.

Because the dynamics of every conversation is different and the subject can change even with instant jokes. Here’s the one that transfers the data every minute in frequency hopping. signal frequency:do not interfere with other devices and may originate from them. changes to prevent parasites.

When Bluetooth first came out, the main problem was its vulnerability, it was not difficult to capture someone’s personal data.

Bluetooth technology has been evolving since the beginning. Over time this situation with add or remove features to secure devices they made it happen. Today, we can securely connect more than one device from our phones or computers as we allow. Just like Harald Bluetooth uniting Denmark and Norway.
