TECH- WHAT IS BLUETOOTH

Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs).

 It  is a wireless technology that uses a radio frequency to share data over a short distance, eliminating the need for wires. You can use Bluetooth on your mobile device to share documents or to connect with other Bluetooth-enabled devices.

 

Bluetooth, developed in the late 1990s, is a technology designed to enable short-range wireless communication between electronic devices, such as between a laptop and a smartphone or between a computer and a television.

A wireless technology that allows the exchange of data between different devices. While Bluetooth uses wavelength to transmit information, it generally only works within a short distance for the devices to stay connected.

 

 It is a handy feature that allows you to easily connect up your various devices, whether you're trying to get your new wireless headphones to talk to your Android phone or connecting your Apple Watch to your iPhone

 A Bluetooth® device works by using radio waves instead of wires or cables to connect with your cell phone, smartphone or computer. So when Bluetooth-enabled products, such as a cell phone and headphones, are in close proximity to each other, they connect, or pair.

 

Is it OK to leave your Bluetooth on all the time?

If your device hasn't been updated, the easiest way to avoid BlueBorne is to disable its Bluetooth and use it as little as possible.  But leaving your Bluetooth on all the time can be dangerous, and hackers are exploiting the technology to access private information, spread malicious software and more.
