Advantages and Disadvantages of Bluetooth Technology | Benefits and Drawbacks of Bluetooth

In today’s post we will learn 10 advantages and disadvantages of Bluetooth technology | drawbacks and benefits of Bluetooth with their explanation, types, and uses.

Bluetooth is a wireless technology that is predominately used for data exchange and data transfer.

The Bluetooth device is a must in mobile devices, which is used for sharing and transferring data and information like audio, video, files, documents, pictures, etc.

Bluetooth is used in Mobile phones, MP3 players, printers, digital cameras, laptops, personal computers, tablets, home music systems, etc.

Dr Jaap Haartsen laid the foundation of Bluetooth in the year 1994. He had experience of more than 25 years in the field of wireless communication technology.

What is Bluetooth Wireless Technology?

Bluetooth is a wireless technology that is designed and developed to transfer data and information between electronic devices.

This Bluetooth can transfer data within a range that varies from 10 meters to 50 meters.

Therefore, as this is a wireless technology, they do not need cables and wires for communication between two or more devices.

There is a limitation on the devices which can connect to Bluetooth, and the limit cannot be exceeded by 7 devices.

Due to some of the silent features, they have become very popular these days and easily replaced old data and wireless communications methods.

Bluetooth technology is constantly working on its data security; therefore, before data exchange and transfer, it asks for a PIN, which must be entered before pairing between two devices.

Bluetooth is a short-range wireless technology built to safely work with 2.4 GHz networks for data transfer between devices.

The first version of Bluetooth was named 1.0. The later new version was launched with better connectivity and performance like 4.0 and 5.0.
