Bluetooth is a widely used cable-replacement technology in the exchange of data, wirelessly, over short distances from fixed and movable devices. Let’s take a closer look!
In layman’s terms, Bluetooth is a simple method to connect a wide range of devices, such as cellphones, PCs, digital cameras, printers and many other gadgets with each other. Bluetooth removes the difficulties of installing cables to connect one device with another. It can also connect different devices, overcoming the problems of synchronization. That means you can connect one type of device with an entirely different type of device, e.g., your computer with a mouse or a mobile phone with a head phone. Bluetooth-enabled gadgets can communicate at ranges of less than 100 meters, depending on the device you are using.

It also enables software program that makes connection among devices possible. So, whenever Bluetooth-enabled gadgets, for example a mobile phone and earphones, are in close distance to each other, they connect with each other, or pair. A single Bluetooth enabled device can even connect to a number of gadgets at the same time. This allows us to talk on the cell phone or listen to songs without the trouble of cables or wires.
