what's the bluetooth
Bluetooth is the name of a wireless technology standard for connecting devices that is 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 hassles. With embedded Bluetooth® technology, all sorts of devices including cell phones, headsets and earpieces, digital cameras and computers, can easily communicate with each other without cables or setup.
