Bluetooth: Bluetooth® is the codename for a technology specification for low-cost, short-range radio links between mobile PCs, mobile phones and other portable devices, and connectivity to the Internet. The Bluetooth specification marks the first time that major players in the converging communications and computer industries have defined a radio standard that allows mobile phones, hand-held computers and PCs to communicate wirelessly with each other without manual intervention from the user. The specification's ability to meet cost/performance needs for a whole raft of applications will be a significant factor in its adoption. Bluetooth is lower in cost than alternative wireless standards and will also often allow a lower cost replacement for cables and connectors, particularly when accounting for installation and maintenance. It is about to revolutionize the personal connectivity market by providing freedom from wired connections.
