Bluetooth technology explained

Bluetooth—named for a 10th-century Danish king, incidentally—uses radio waves to transmit information between two devices directly. The radio waves used by Bluetooth are much weaker than those involved with Wi-Fi or cellular signals, two other common ways to connect devices.

What technology is used in Bluetooth?

Bluetooth is a short-range wireless communication technology standard. Bluetooth uses short-wavelength UHF radio waves of a frequency range between 2.4 and 2.485 GHz.

What is difference between Wi-Fi and Bluetooth?

Bluetooth allows for short-range data transfer between devices. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Wi-Fi, on the other hand, allows devices to connect to the Internet.

What are the three main uses of Bluetooth technology?

To transfer data files, videos, and images and MP3 or MP4. In wireless peripheral devices like mouse and keyboards. In data logging equipment. In the short-range transmission of data from sensors devices to sensor nodes like mobile phones.

How does Bluetooth work without Wi-Fi?

Bluetooth works by using radio waves to connect two devices, such as your phone and computer. You don't actually need a phone signal or internet connection to use Bluetooth. This means that it can work anywhere in the world, as long as the devices you're trying to link are both Bluetooth-compatible.
