Bluetooth Advantages & Disadvantages

By Steve Johnson

Bluetooth is one of the most convenient developments in wireless technology. Bluetooth usage has increased over time from mobile phones, headsets, laptops, printers and music players to HD televisions. Like all other technologies, though, it has flaws.

Ease of Access

Unlike a wireless Local Area Network (LAN), Bluetooth doesn't need any configuration to start a connection and perform file transfers. Consequently, Bluetooth is a great alternative for business environments in which wireless file transfers are utilized. In laptops, establishing a wireless connection is as easy as pressing the Bluetooth shortcut or hot key.


The Bluetooth connection can be securely established without interference from unrecognized devices by entering an identification number for the connection. The user of the master device--the one which starts the connection--can opt to enter a PIN which creates the secure usage loop.


Unless a device is already paired to your device, you have the option to accept or reject the connection and file transfer. This prevents unnecessary or infected files from unknown users from transferring to your device.

Free Access

Accessing a Bluetooth device doesn't cost money; all you need is the Bluetooth capability.


Bluetooth has a downside when it comes to file sharing speed. Compared to the up to 4.0MBps rate transfer of infrared, Bluetooth can only reach up to 1.0MBps, meaning that it transfers files slowly. In transferring or sharing larger files at a closer distance, other wireless technology--like infrared--is better.


Bluetooth is not recommended for establishing Internet connections because of its limited transfer rate. A LAN connection is more efficient.
