What Is Bluetooth?

Bluetooth is a wireless communication standard geared toward removing the wires between computers and their peripherals. For example, you can purchase a Bluetooth keyboard, mouse, and printer to eliminate the wires that typically connect these peripherals to your desktop or notebook PC. Similarly, Bluetooth has become popular in the mobile realm for using a mobile headset or hands-free car kit to communicate with a mobile phone. This is the most common application of Bluetooth to Treo devices.

Bluetooth effectively enables you to operate a wireless network limited to a very small area (usually up to 10 meters, or 32 feet). For a Treo device using Bluetooth, the “network” consists of your Treo and a Bluetooth headset, hands-free car kit, or GPS receiver, to name a few examples. Bluetooth devices communicate over a 2.45 gigahertz (GHz) radio connection, similar to the one used by baby monitors, garage door openers, and cordless phones. For this reason, interference is technically possible if you operate a Bluetooth headset with your Treo in the same area as other wireless equipment. However, the specific design of the Bluetooth communication protocol helps alleviate the problem.
