IEEE 802.16 is an emerging standard which is intended to allow for multiple
vendors to produce interoperable equipment for broadband wireless networks
while still allowing an extensive vendor differentiation. The tutorial covers
this topic which is extremely hot right now in academia, research
communities, and industries, due to the publications of the IEEE 802.16
standards.
The main goal of this tutorial is the analysis and discussion of the potentials of
IEEE 802.16 standard in the design of broadband wireless networks.
Fundamental issues related to 802.16 systems are investigated in order to
highlight the potentials of a technology which appears as one of the favorite
candidates in the definition of standards for next generation wireless
networks for the radio local loop connectivity.

Fethi Filali (Fethi.Filali@eurecom.fr) received his Computer Science Engineering and DEA degrees from
the National College of Informatics (ENSI) in 1998 and 1999, respectively. At
the end of 1999, he joined the Planète research team at INRIA (National
research institute in informatics and control) in Sophia-Antipolis to prepare a
Ph.D. in Computer Science which he has defended on November 2002. During
2003, he was an ATER (Attaché Temporaire d'Enseignement et de Recherche)
at the Université of Nice Sophia-Antipolis (UNSA) and he joined on September
2003 the Mobile Communications department of Institut Eurécom in Sophia-
Antipolis as an Assistant Professor. He is/was involved in several Frenchfunded
(Dipcast, Constellation, Rhodos, Cosinus, Airnet) and IST FP6 (Widens,
Newcom, Daidalos, E2R, Multinet, Unite, Chorist) projects. In the context of
some of these projects, he designed and developed an open, flexible and
efficient architecture for the support of heterogeneous radio technologies.
This architecture was integrated in Eurecom's wireless software-radio
platform. His current research interests include WIMAX (802.16)-related
communication mechanisms, QoS support in IEEE 802.11-based networks,
sensor and actuator networks (SANETs), vehicle adhoc networks (VANETs),
routing and TCP performance in wireless networks. He served as a technical
reviewer of several international conferences and journals and he is currently
a PC member of ACM/IEEE MSWIM 2006. Additionally, he is a member of IEEE
and IEEE Communications Society. Visit Fethi Filali’s web page for more information about his research
activities. |
