Tutorial Proposal Title: - “Broadband Wireless: WiMAX” Abstract: BWA is promising to make ubiquitous broadband wireless access a reality. Emerging technologies like Worldwide Interoperability for Microwave Access (WiMAX) and UMTS Long Term Evolution (UMTS-LTE) are good candidates to deliver last mile broadband connectivity over large geographic areas. IEEE 802.16e (Mobile WiMAX) is part of ITU’s IMT-2000 family of standards and promises to provide high data rates over large geographic areas. WiMAX can enable pervasive, high speed data access to range of mobile devices. Over the years the volume of data handled by wireless networks has grown exponentially but at the same time the revenues have flattened. Hence next generations standards have to look for ways to reduce capital and operational expenditure. WiMAX is the first all IP solution that has the potential to provide an efficient and scalable network to support multimedia applications. With 500+ network deployments in 140+ countries, WiMAX today is a realistic option for ubiquitous broadband access. WiMAX forum has already submitted its proposal to IMT-A based on IEEE 802.16m standards and will no doubt be a strong competitor to LTE, specifically in the developing world. This tutorial presentation would provide a detailed view of the important technologies behind WiMAX systems and how they are proposed to be implemented.
Duration: - Half day (210 Minutes) Goal and Objectives: The objective of the proposed tutorial is to provide an in depth understanding of the key technical concepts behind WiMAX. With the conference aim to foster research in ultra modern wireless communication, the topic of this presentation would be of great interest to all the participants.
Scope: This tutorial would be suitable for academicians and practitioners with exposure to any cellular or broadband wireless technology.
Teaching Method: It is proposed to be organized as a three hour and thirty minutes long session divided into two halves. Multimedia presentation is proposed to be used.
