Bluetooth technology allows your cell phone to be aware of other Bluetooth-enabled devices that are physically nearby. This means that your cell phone can intelligently communicate with other Bluetooth headsets and devices. For example, a wireless hands-free headset, to eleiminate clumsy wires in order to use your headset. As Bluetooth becomes a part of all electronic products, you'll be able to do incredible things like control your TV or remotely start your car with your cell phone!

BMW was the first motor vehicle manufacturer to install handsfree Bluetooth technology in its cars, adding it as an option on its 3 Series, 5 Series and X5 vehicles. Since then, other manufacturers have followed suit, with many vehicles, including the 2004 Toyota Prius and the 2004 Lexus LS 430. The Bluetooth car kits allow users with Bluetooth-equipped cell phones to make use of some of the phone's features, such as making calls, while the phone itself can be left in a suitcase or in the boot/trunk, for instance.
However, the standard also includes support for more powerful longer-range devices suitable for constructing a wireless LAN. Every Bluetooth device can simultaneously maintain up to 7 connections, but only one active connection at the time. These groups (maximum of 8 devices: 1 host and 7 slaves) are called piconets. The Bluetooth specification also enables the possibility of connect two piconetworks together, with one master device acting as a bridge. These devices have yet to come, though are supposed to appear within the next two years. Every device can be configured to constantly announce its presence to nearby devices in order to establish a connection. It is also possible to password protect a connection between two devices so that no one can listen in.
The protocol operates in the license-free ISM band at 2.45 GHz. It reaches speeds of 723.1 kbit/s. In order to avoid interfering with other protocols which use the 2.45 GHz band, the Bluetooth protocol divides the band into 79 channels and changes channels up to 1600 times per second.
Bluetooth should not be compared to Wi-Fi, which is a faster protocol requiring more expensive hardware that covers greater distances and uses the same frequency range. While Bluetooth is a cable replacement creating personal area networking between different devices, Wi-Fi is a cable replacement for local area network access.
Many USB Bluetooth adapters are available, some of which also include an IrDA adapter.
