What is it?
Bluetooth is a wireless standard that allows data to be exchanges wirelessly over short spaces. It can be used to send content from one device to another, for example, sending music between a mobile and a PC or laptop. You can find Bluetooth on many smartphone devices but you can also find it in the form of a headset.
How does it work?
Instead of using cables or wires Bluetooth uses radio waves to connect to a device to send and receive data in a band of 79 different channels. Because of the short-range network, Bluetooth allows you to connect to another Bluetooth user within a range close to your device. According to the Bluetooth website, “when two Bluetooth devices want to talk to each other, they need to pair. Communication between Bluetooth devices happens over short-range, ad hoc networks known as piconets. A piconet is a network of devices connected using Bluetooth technology. When a network is established, one device takes the role of the master while all the other devices act as slaves. Piconets are established dynamically and automatically as Bluetooth devices enter and leave radio proximity.”
What are the limitations/abilities of using this type of using it?
An advantage of Bluetooth is that it is cheap (as a handset) and comes along free with most, if not all smartphone devices. It is wireless which is very handy and convenient if you don’t have a cable and want to use it when you’re outside and is very easily to use and quick to connect. A disadvantage is that it has a very short range and uses up a lot of battery life on your phone.
I like to use Bluetooth to connect my phone to my car so I can listen to the music on my phone rather than music on the radio.
