Bluetooth enables users to connect a wide range of computing and telecommunication devices without any additional or proprietary cables. Bluetooth provides short-range, low-cost (_≤ $10 per device) connectivity between portable devices. Bluetooth is limited in range (_10 meters) and bandwidth (780 kbps compared to Home RF that goes to 1–2 Mbps and IEEE 802.11b that goes to 11 Mbps with 150 m and greater distance). Bluetooth radio characteristics [8–10] include low power, short range, and medium transmission speed. The low power consumption makes Bluetooth ideal for small, battery-powered devices like mobile phones and pocket PCs. Bluetooth is poised to capitalize on the emerging market of small mobile devices that is expected to grow. Bluetooth’s short range (≤ 10 m) is ideal for the concept of “personal operating space” and integrates the notion of using a device carried or worn on the body or otherwise located within immediate reach. Bluetooth’s transmission speed of 780 kbps works well for transferring small to medium-sized files. Bluetooth enables users to connect a wide range of computing and telecommunication devices easily and simply, without the need to buy additional or proprietary cables. The cable solution is complicated since it may require a cable specifi c to the device that is being connected. The infrared solution eliminates the cable, but requires line of sight. To solve all these problems the Bluetooth standard has been developed. The Bluetooth
