Abstract
Broadband
wireless access
is the third wireless revolution, after cellphones (1990s) and Wi-Fi
(2000s).
It is viewed by many carriers and cable operators as a
“disruptive” technology
and rightly so. The broadcast nature of wireless transmission offers
ubiquity
and immediate access for both fixed and mobile users, clearly a vital
element
of next-generation quadruple play (i.e., voice, video, data, and
mobility)
services. Unlike wired access (copper, coax, fiber), a large portion of
the
deployment costs is incurred only when a subscriber signs up for
service.
is poised to exploit new wireless access technologies capable of
pervasive
high-speed connectivity despite lagging behind developed Asian
countries in
broadband access deployment for many years. An increasing
number of U.S.
municipal governments are financing the deployment of multihop wireless
networks with the overall aim of providing ubiquitous Internet access
and
enhanced public services. This
presentation will provide a comparative assessment of the key issues
and
technologies underpinning promising broadband wireless access solutions
such as 802.16 (Wi-Max), long-range/multihop 802.11 (Wi-Fi), wireless
DOCSIS,
3G/4G, 802.20 (mobile broadband), 802.21 (media independent handoff and
interoperability), and the emerging 802.22 (wireless regional area
networks)
standard. Key topics include licensed and unlicensed spectrum
consideration,
reliable physical layer transmission using multiple antennas,
multichannel
medium access protocols with QoS provisioning, wireless access
topologies:
point-to-point, point-to-multipoint, peer-to-peer multihop (mesh),
wireless
multimedia services: wireless IP-TV, wireless VoIP, cognitive radio
technologies, advanced wireless security, wireless/wireline integration.
Bio:
Benny Bing is a research faculty member with the School of Electrical
and Computer Engineering at the Georgia Institute
of Technology (Georgia Tech), USA. He is also an associate director of
the Georgia
Tech Broadband Institute. He has published over 40 papers, 8 books, and
1 book
chapter. His publications have also appeared in the IEEE Spectrum. His
books on wireless networks are highly regarded by many technology
visionaries.
They contain forewords from both chairmen of the IEEE 802.11 Working
Group
since its inception, the inventor of Internet technology, and the
inventor of
the first wireless protocol. In
early 2000, his groundbreaking book on wireless LANs was adopted by
Cisco
Systems to launch the Cisco-Aironet Wi-Fi product. The product has
since
enjoyed phenomenal success, dominating the corporate arena and
capturing over
60% of the Wi-Fi market share. He was subsequently invited by Qualcomm
Inc. in San
Diego, CA to
conduct a customized course on wireless LANs for its engineering
executives. He
was again invited to conduct a similar course for the Office of
Information
Technology. In 2002, his edited book on wireless LANs was extensively
reviewed
by the IEEE Communications Magazine, IEEE Network, and ACM
Networker, the first time a book has been reviewed by all three
journals.
He
is currently an editor for the IEEE Wireless Communications Magazine,
and has also guest edited for the IEEE Communications Magazine and the
IEEE
Journal on Selected Areas on Communications. In addition, he was
featured
in the MIT Technology Review in a special issue on wired and wireless
technologies as well as the Atlanta Business Chronicle. He has served
on
the wireless networking panel for National Science Foundation (NSF) and
was
selected as one of the 10 best wireless designers in the United States
by Building Industry Consulting Services
International (BICSI), a 22,000-industry member telecommunication
association
based in Tampa, Florida. He was invited by NSF to participate in an
NSF-sponsored workshop on “Residential Broadband Revisited:
Research
Challenges in Residential Networks, Broadband Access and
Applications”, held on October 2003. He is also a frequent
tutorial
presenter at several IEEE Communications Society flagship conferences
such as IEEE
Infocom and IEEE Globecom. Among the industry sponsors for his
research include Comcast, Cox, Arris Broadband, Panasonic, and
Broadcom. He
is a recipient of the Lockheed-Martin Fellowship and a best paper award
at the 1998
IEEE International Conference on ATM. He is a Senior Member of IEEE and
has
over 100 international research citations to his name. His current
research
interests include broadband access, wireless LANs, distributed
multichannel
protocol design, and queueing theory.
