Bluetooth
- Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Today Bluetooth is managed by the Bluetooth Special Interest Group.
Uses
- Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 100 m, 10 m and 1 m, but ranges vary in practice; see table below) based on low-cost transceiver microchips in each device.Because the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other.
- In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to a pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices.
- While the Bluetooth Core Specification does mandate minimums for range, the range of the technology is application specific and is not limited. Manufacturers may tune their implementations to the range needed to support individual use cases.
Bluetooth vs. Wi-Fi IEEE 802.11 in networking
- Bluetooth and Wi-Fi have many applications: setting up networks, printing, or transferring files.
- Wi-Fi is intended for resident equipment and its applications. The category of applications is outlined as WLAN, the wireless local area networks. Wi-Fi is intended as a replacement for cabling for general local area network access in work areas.
- Bluetooth is intended for non-resident equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications in any ambiance and can also support fixed location applications such as smart energy functionality in the home (thermostats, etc.).
- Wi-Fi is a wireless version of a traditional Ethernet network, and requires configuration to set up shared resources, transmit files, and to set up audio links (for example, headsets and hands-free devices). Wi-Fi uses the same radio frequencies as Bluetooth, but with higher power, resulting in a faster connection and better range from the base station. The nearest equivalents in Bluetooth are the DUN profile, which allows devices to act as modem interfaces, and the PAN profile, which allows for ad-hoc networking.
Bluetooth devices
- Bluetooth exists in many products, such as the iPod Touch, Lego Mindstorms NXT, PlayStation 3, PSP Go, telephones, the Nintendo Wii, and some high definition headsets, modems, and watches. The technology is useful when transferring information between two or more devices that are near each other in low-bandwidth situations. Bluetooth is commonly used to transfer sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files).
- Bluetooth protocols simplify the discovery and setup of services between devices.[citation needed] Bluetooth devices can advertise all of the services they provide. This makes using services easier because more of the security, network address and permission configuration can be automated than with many other network types.

How to Use a Bluetooth USB Adapter:
- Insert the USB adapter in the open USB port if using a Mac-based computer, and skip to Step 4. If using a Windows-based machine, move on to Step 3.
- Insert the installation CD, and follow the instructions to install the software and the drivers necessary to run the adapter. The software may require you to launch additional applications to configure the peripheral. Follow your adapter's included user manual for specific steps, which may vary from model to model.
- With the software installation complete, insert the Bluetooth adapter into the open USB slot.
- Ensure that your Bluetooth settings are set to "discoverable," which means the peripheral will be able to see other devices that are Bluetooth-capable and also "discoverable" as well.
- Connecting a Bluetooth-Enabled Device:
- Turn on Bluetooth on both the computer and the device you are trying to connect. Either the computer or the device itself should detect the other to begin the connection process.
- Select the detected device on your computer (or conversely the detected computer on the device, either way will work). The connection process should begin, and in some cases you will be asked for a PIN.
- Take note of the PIN given by either Bluetooth-enabled device, and enter it into the other device if it asks for it. The PIN will be verified, and, upon verification, the two devices will be "paired."
