What is Bluetooth?

Tim Rohaly

Bluetooth is a wireless point-to-point networking specification. It is short-range (10m), low-power (100mW), spread-spectrum (2.402-2.480 GHz), high-speed (1 Mbps), and low-cost. It is intended for use as a personal-area network - connecting devices such as cell-phones, PDAs, printers, and headsets together when they are near each other.

The Bluetooth consortium is led by 3Com, Ericsson, IBM, Intel, Lucent, Microsoft, Motorola, Nokia and Toshiba, and consists of almost 2000 member companies. More information can be found at the consortium web site, http://www.bluetooth.com/.
