What is Bluetooth?
Bluetooth is the name of a wireless technology standard which allows different types of electronic devices to interact via short-range radio waves. Because of the versatility of Bluetooth wireless technology, enabled devices do not share all of the same profiles. The Bluetooth Handsfree System system is compatible with Bluetooth-enabled phones that have a hands-free profile. The standard allows a wide range of devices to communicate with each other, with minimal user effort.
Bluetooth allows you to make wireless connections between various devices. It works on a low powered radio connection and can connect laptops, phones and PDAs without the need for cables. Because Bluetooth acts in all directions, unlike Infrared, the devices don’t need to be pointing directly at each other. To create a secure connection between devices using Bluetooth, you will need to exchange Bluetooth passcodes with the device you are connecting to for the first time. This operation is called ‘pairing’. It ensures that your phone connects with the correct device and not another within the vicinity. When Bluetooth is activated on your phone, it gives out radio waves around the phone, which senses its partner Bluetooth device.
Bluetooth® is the name of a wireless technology standard for connecting devices, set to replace cables. It uses radio frequencies in the 2.45 GHz range to transmit information over short distances of generally 33 feet (10 meters) or less. By embedding a Bluetooth® chip and receiver into products, cables that would normally carry the signal can be eliminated. While entertainment centers, computer systems, handheld PDAs, digital cameras and MP3 players, continue to flourish, manufacturers and end-users alike are plagued by the growing complexity of connecting devices. Proprietary cables, protocols and cradles simply complicate things as companies seek a larger market share while buyers seek user-friendly gadgets that are compatible with other products. Enter the Bluetooth® standard. Idealized by a group of electronics manufacturers looking for a streamlined solution to a growing problem, it promises to uncomplicate the interconnectivity of devices, easing manufacturing woes and end-user
