Bluetooth is a short-range wireless technology designed to replace wired connections between electronic devices. Named for a 10th Century Viking who united Norway and Denmark, Bluetooth makes it possible for Pocket PCs to connect to cell phones, printers, computers and more, all without wires.

Primarily, Pocket PC users benefit from Bluetooth for two reasons: The first is Bluetooth's ability to create a wireless Internet connection between a Pocket PC and Bluetooth-capable cellular phones, transforming a data-capable phone into a wireless modem. The second is Bluetooth's ability to establish a wireless connection between a Pocket PC and a computer -or even two Pocket PCs - for data exchange.
