This course has been designed for people developing products and services that leverage Wi-Fi, as well as people considering the use or expanded use of WLAN technologies in their own organizations. Unlike recent IEEE course programs on WLANs which are directed at IT managers who must deploy, manage and support the technology, this course is intended for people needing to make fundamental decisions about how to use or respond to the technology, as well as wanting to understand the nature of the technology. Peter explains in detail the key advantages and disadvantages of wireless local-area technologies compared to wide-area technologies. He examines in detail the capabilities and mechanisms of the evolving IEEE standards, including 802.11b, 802.11g and 802.11a. As important are the supporting standards such as IEEE 802.1x and 802.11i for security, 802.11e for quality of service to support voice and video and 802.11n for yet higher speeds. Included are timetables and the implications for new applications and markets. The session also considers Bluetooth, and whether wireless personal-area networking technologies are on a collision course with WLANs. The course takes a hard look at hotspot developments, examines deployments, how cellular operators are integrating hotspots, common authentication schemes, how hotspot operators are working with each other, how the Wi-Fi Alliance is supporting roaming through its Wireless ISP Roamer (WISPr) specification, and just how many hotspots are needed for truly ubiquitous service. Peter also examines the business model challenge, along with other related market developments such as Wi-Fi efforts by key players in the computer industry. Part of the big picture are spectrum considerations. The FCC has already assigned more spectrum for Wi-Fi than all of cellular and PCS. Peter discusses what this means for the wireless industry overall, and what the broadband future of wireless may look like. As someone who has been involved at deep technical levels and also in market analysis of wireless technologies since 1990, Peter Rysavy provides unique insights into a complex and rapidly evolving area.

Instructor's Biography Peter Rysavy is the president of Rysavy Research, a consulting firm that provides clients both details and insight into wireless networking. His broad experience working with carriers, infrastructure vendors, applications developers, investors, market research firms and standards organizations gives him a unique and comprehensive perspective on the industry. Since 1993, his firm Rysavy Research, has helped clients develop strategic directions, conduct market research, and develop wireless applications. >From 1988 to 1993, Peter was vice-president of engineering and technology at LapLink.com where projects included LapLink, LapLink Wireless and connectivity solutions for a broad variety of mobile platforms. Prior to that, he spent seven years at Fluke Corporation where he designed communications hardware and software for data acquisition products. Peter is the chair of the Standards and Architecture Committee and executive director of the Portable Computing and Communications Association (PCCA), a group that promotes wireless-data interoperability. Peter graduated with BSEE and MSEE degrees from Stanford University in 1979.
