A Person Centered Network Concept: WPAN

Authors : D Vijaya kumar , B Krishna Mohan and M S R Shekar

Abstract: A Wireless Personal Area Network (WPAN) is a new wireless technology, which provides short-range (up to 10m) connectivity between the personal devices such as sensors, laptops, digital cameras, digital audio and video players etc., without cables. The wireless personal area network is new standard under development, as a part of the IEEE 802.15 standard. The IEEE 802.15 working group has concentrated on three classes of WPAN that are differentiated by data rate, power consumption and quality of service (QoS). The activity with in IEEE 802.15 is divided into four tasks groups i.e., 802.15.1 to 802.15.4 concentrated on different issues. Basically the WPAN uses two technologies to provide wireless connectivity among the personal devices. Those are IrDA-Data and Bluetooth. IrDA-Data (Infrared Data Association) is based on infrared (IR) communication and provides a simple, inexpensive means of short-range fast data rate for wireless data communication. Where as Bluetooth is based on radio frequency (RF) communication and provides short-range, low power, and high bandwidth wireless communications. The bluetooth radio operates in the 2.4 GHz ISM band. Bluetooth and IrDA technologies are compared based upon their wireless medium, mobility, and cost.
