What Is Bluetooth Technology & How Does It Work?

By Luke Arthur

In the world of wireless networking, Bluetooth is one of the technologies that you are likely to come across. Bluetooth technology involves short waive radio transmissions and it aims to eliminate the need for cables and wires. It can be used with computers, mobile phones and other electronic devices in the office.

What is Bluetooth?

Bluetooth is a technology that is used to send signals between electronic devices. The ultimate purpose of this technology is to get rid of cables and make your office and your life easier to work with. Instead of relying on cables, one device can send a wireless signal to another and be interpreted instantaneously. This gives you acceptable functionality without having to worry about plugging in your devices or tripping over wires all the time.

How it Works

Bluetooth is a technology that is meant to be used in a short range environment. For example, many Bluetooth devices have a range of about 30 to 40 feet. In some cases, you can get Bluetooth devices that have a range of up to 100 feet. When you use a Bluetooth device, it encodes information in a radio signal and broadcasts it out to other Bluetooth enabled devices in range. The other device then picks up on the signal and completes an action.

Bluetooth Devices

In the world of technology today, you will find many devices that are Bluetooth enabled. For example, most of the cellphones on the market today have Bluetooth capabilities. Most computers now also are compatible with Bluetooth technology. Besides computers and phones, you can also find it in headphones, speakers and other home entertainment devices. You can also find it in office accessories such as printers, keyboards and computer mice. It is also becoming more common in vehicles.


Bluetooth can be used to transfer information wirelessly or it can be used to control other devices. For example, if you are using a Bluetooth keyboard, you can type and the commands will be sent to your computer. You can use a Bluetooth headset for your cellphone and talk without having to hold the phone up to your ear. You could also transfer files between your computer and your phone, or between two mobile phones.
