bluetooth-svgBluetooth describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection. Using this technology means people can transfer data from one device to another fairly easily.

How it workseach device will have Bluetooth connectivity, an antenna-equipped chip in both devices sends and receives signals at a specific frequency. The software interprets incoming Bluetooth signals and sends them out in ways other devices can read and understand

When two devices are equipped with Bluetooth, usually one of them will be set to be discoverable, meaning it’ll show up in a list of Bluetooth devices in the area on your phone or other controlling devices.


  • Bluetooth is free of charge
  • You don’t need a cable to transfer data as Bluetooth is wireless
  • In order to make a transfer or allow someone to access the files on your phone, you will have to give them access by accepting or rejecting the request through your phone.


  • When you leave your Bluetooth enabled all day, this will decrease your battery power.
  • When using Bluetooth you can only use it if the 2 devices are at a short range, for example, you could use Bluetooth if one device is in the next room, but you couldn’t use Bluetooth if one device was at home and the other device was at work.

I use Bluetooth alot between my phone and my laptop. For example if there is a picture on my phone that I want to use in a assignment I will bluetooth the picture to my laptop as its a lot quicker than emailing the picture or plugging my phone into my laptop. However I think the range could be improved so you could bluetooth a file from work to home.
