1. Introduction
1.1 Bluetooth Technol ogy
Bluetooth is an internationally standardized technology supporting short distance wireless communications. Any
two Bluetooth-compatible equipment, such as mobile ph one, PDA、PC, headset, mouse, keyboard, printer, etc. can
wirelessly communicate with each other via Bluetooth co nnection. To ensure worldwide compatibility, Bluetooth
operates on the globally avail able ISM (Industrial Scientific and Medical) frequency band. Within 2.4 GHz and
2.48 GHz, Bluetooth transmits data up to either 10 meters (CLASS II mode) or 100 meters (CLASS I mode) using
79 frequency hopping channels.
Though line-of-sight is not required, Bluetooth connections could be subject to interferences from obstructions such
as walls, human body, and other electronic devices. In addition, due to variations on product implementation, it is
likely that Bluetooth equipments from different manufactures have interoperability issues. In that case, you may
