Bluetooth Performance Analysis in Personal Area Network (PAN)

Bluetooth is a telecommunications industry specification operating in an unlicensed frequency band of 2.4 GHz that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection. In this study, a personal area network (PAN) was set up using three personal computers, two Bluetooth universal serial bus dongles, one serial Bluetooth module and also a Bluetooth mobile phone. A graphical user interface (GUI) using Visual Basic 6.0 was built to display the system accessibility such as file and system properties, transferring text files, chatting program and network detection by Bluetooth's service discovery protocol (SDP). The Bluetooth system performance is observed between two Bluetooth devices using the GUI and analyzed in terms of types, sizes of file and separation distance (within 8 meters), which were measured against transmission delay. The findings show that the transmission delay varies exponentially with the types and sizes of file even with different types of Bluetooth devices and increases with separation distance
