(1)Bluetooth Specifications

Here you can get information about the technical features of Bluetooth technology, from the table below.

(2)Different versions of Bluetooth Technology

Here we will learn about the different versions of Bluetooth technology, we will also learn about the difference between them. Well if the talk about Bluetooth versions works then v1.2, v2.0, v2.1, v3.0, v4.0, v4.1 and v5.0 are the main ones.

Bluetooth technology primarily provides short-range wireless capabilities to do data transfer between two devices. In the last few years, many versions of Bluetooth have come in the market and Bluetooth has evolved to a great extent, in which many versions such as v1.2, v2.0, v2.1, v3.0, v4.0, v4. 1 and v5.0 are included. Bluetooth operates in 2.4 GHz ISM frequency band. These technologies are based on the IEEE 802.15.1 standard. Both PHY and MAC layers of Bluetooth have been defined in the Wireless Personal Area Network (WPAN) standard.

All Bluetooth versions have different speed and data rate requirements. They are compatible with their previous versions, so that the version of Bluetooth in the device can easily operate with another version. Bluetooth network is primarily a combination of many piconets. Each piconet has a master and seven slaves that are communicate with each other.

Bluetooth RF and baseband specification

(3)Applications of Bluetooth Technology

We have learned about Bluetooth technology very well now. Let us now know how we use this Bluetooth technology in our daily lives.

1)We use it to transfer files such as images, mp3 audio, video, GIFs etc. from one mobile to another.

2)A small amount of bandwidth seems to be connected between laptops and desktop computers for wireless networking.

3)We can connect all the peripheral devices such as mouse, keyboard, printers, speakers, etc. with cordlessly easy PC.

4)You can print out of your computer without any wires.

5)The whole house can automated.

6)You can lock your cars more securely with the help of Bluetooth.
