Wireless Technology
-
Bluetooth is, first and foremost, a wireless communication technology. What this means is that Bluetooth enabled devices can exchange information without the often problematic need to plug in cables and wires. Bluetooth does this by converting data into radio signals that are then transmitted from one device to another. In this way it also makes it possible for devices that couldn't normally exchange information, such as a cell phone and a printer, to communicate with each other.
How it Works
-
The first step is for Bluetooth devices to recognize each other. Let's say you have a Bluetooth enabled cell phone, it will put out a radio signal that will be picked up and recognized by other Bluetooth devices close by. Once the Bluetooth devices have communicated (think of it as introducing themselves and connecting) you now have the option of sending data from one Bluetooth device to another. If you had a list on your Bluetooth enabled cell phone, and it communicated with a Bluetooth enabled printer, you could then print your list straight from your cell phone.

Applications
-
Bluetooth technology is, first and foremost, amazingly convenient. Without wires, technology can be much more conveniently arranged. Additionally, it allows devices to communicate much easier. However, Bluetooth technology does cost a little bit extra for all of its convenience. But for the ability to make things easier (such as sending documents to a printer from your cell phone), or even safer (using a Bluetooth headset to talk on your cell phone while driving rather than holding the phone itself), the cost is worth it to most Bluetooth customers.
