Overview

Introduction to Bluetooth Wireless Technology

Bluetooth™ wireless technology allows you to make short-range wireless connections to Bluetooth devices, such as cellular phones, personal digital assistants (PDA), and desktop and notebook computers. Because Bluetooth wireless technology uses radio transmission, voice and data are transmitted almost immediately. Bluetooth transmission ensures both protection from interference and secure data transfers.

You might use Bluetooth wireless technology in these ways:

nDial up to the Internet on your notebook over your Bluetooth cellular phone.

nSend a fax from your notebook over your Bluetooth cellular phone.

nSynchronize your Bluetooth PDA with your notebook.

nSend your business card to anyone in a meeting who has a Bluetooth device.

nSend or receive ﬁles to or from anyone in a meeting who has a Bluetooth notebook or PDA.
