What is Bluetooth And How Does it Work?

This is a great way to transfer data. Due to its many applications in recent times, this Bluetooth has become a part of our life. Be it audio devices, mobile phones, home stereos, MP3 players, laptops, desktops, tables, etc. You name any electronic device and you will definitely see Bluetooth there.

No matter which device it is, everyone needs to transfer data. If you want to send data (audio, graphics, image, files, videos) from your smartphones to other phones, then you can do it through Bluetooth. But the most important thing in this is that both devices should have Bluetooth facilities.

If you want to get complete information about Bluetooth then you have to read this article completely.

What is Bluetooth?

Bluetooth is a wireless technology that transmits data between electrical devices. If we talk about other wireless communication modes, then the distance of data transmission here is very less as compared to them.

This means that data transfer can happen via Bluetooth within a very short distance. Using this technology, users do not need any cords, cables, or adapters and it allows them to communicate wirelessly.

Wireless technology known as Bluetooth is utilized to transport any kind of data or file. The actual range of this Bluetooth technology, which was created by the Bluetooth Special Interest Group, is just 10 to 50 meters.

Only seven devices, mostly found in the smartphone, personal computer, and gaming console industries, can be linked to this Bluetooth device at once. IEEE standardized Bluetooth as IEEE 802.15.1, but these standards were maintained for only short periods.

What are the Key Features of Bluetooth Technology?

Let us know what are the key features of this Bluetooth technology, about which you all must know:

•  Less complexity: This is a relatively straightforward technique, thus there isn't much complexity involved.
• Less power consumption: There is not much power consumption in this. Which makes it more popular.
• Lower Prices: Compared to other related technologies, they are less expensive.
• They are extremely resilient. They are usable anytime and everywhere.
• Distance: They are usable from 10 to 50 meters away.
• Data Transfer: They can transmit data at a rate of up to 1 Mbps. which moves really quickly.
• Spreading: This makes use of FHSS (Frequency Hopping Spread Spectrum) technology.

Advantages of Bluetooth

Here I am going to tell you about the advantages of Bluetooth.

•      Using this you can connect immediately through an ad-hoc connection without any wires. It is very easy and quick to have a connection established here. The user only has to pair the devices.
•         It has low power consumption.
•        Data transfer can also happen from between the walls.
•          Its range is better than Infrared communication.
•         It is used for both speech and data transmission.
•           Data connection in this technique is particularly safe because FHSS is used.
•     Many goods, including headphones, automotive systems, printers, webcams, GPS systems, keyboards, and mice, utilize this technology.
•       Since nowadays Bluetooth headphones are available in the market, a driver can receive phones comfortably while driving. Due to this, he will not have any problem in driving.
•     Everyone can purchase these Bluetooth gadgets because they are inexpensive and readily available.
•      There is very little interference in this if we talk about other wireless technologies then because the FHSS technique is used in it.

Disadvantages of Bluetooth

Just like there are two sides of a coin, similarly everything has advantages and disadvantages:

•       Its biggest disadvantage is its security. Yes because as we know that it operates on radio frequency and hence it can penetrate walls easily. That's why you are advised not to use it for critical business or personal data transfer.
•     Since Home RF technology also operates on the same frequency, there is interference with each other at times.
•      Its bandwidth is much lower in comparison to WiFi.
•      Battery usage is more in this when Bluetooth is in ON condition. That's why it is recommended to turn off Bluetooth when not in use, which also increases the battery life of the mobile.

What is Bluetooth Network And Its Types?

A Bluetooth network is called a network where many Bluetooth users are connected and communicating. There are mainly only two main elements in these networks, the first Master and the second Slave.

Mainly two types of network topologies have been given more importance in Bluetooth.

1) Piconet

2) Scatternet.

Piconet

A piconet is formed when one master and one slave are present or one master and multiple slaves are present. Only a maximum of 7 active slaves can remain in the piconet. That's why a maximum of 8 maximum devices can communicate together in a small network and which is called a piconet.

Scatternet

Combinations of Multiple Piconets are called scattered. A device can participate in multiple piconets. It has to be a timeshare and also has to be synchronized with the master of the current piconet.

It supports data rates that are based on different versions, which are something like this from 720 kbps to 24 Mbps. They have the ability to cover a distance of 1 to 100 meters depending on the power class of the Bluetooth device it supports.

Applications of Bluetooth Technology

We have already learned about Bluetooth Technology very well, now let us know how we use this Bluetooth Technology in our daily life.

•       We use it to transfer files like images, mp3 audio, video, GIFs, etc. from one mobile to another.
•      We can easily connect all peripheral devices like mouse, keyboards, printers, speakers, etc. to PC wirelessly.
•       You can print it out from your computer without any wires.
•       The whole house can be automated.
•       You can lock your car more securely with the help of Bluetooth.

Where Do We Use Bluetooth Technology?

• Bluetooth headsets
• Stereo headset
•  In-car Bluetooth headset
• Bluetooth-equipped printer
• Bluetooth enables a webcam
• Bluetooth keyboard
• Bluetooth GPS device
