Message-ID: <3CA4A9D0.30340.1D9C433@localhost>
Dear IEEE ComSoc Member or friend of IEEE,
The IEEE Northern Virginia Communications Society's next few months' programs will be of great interest to you. Topics include XM
Radio (headquartered here in Washington, D.C.), IEEE 802.11b, the wireless LAN standard that promises to be the 'disruptive
technology' of the next few years, George Mason University's work on Project SOPRANO (Self-Organizing Packet Radio Ad-Hoc
Networks with Overlay), and NASA near-earth-orbit mission support by the Goddard Space Flight Center. I do hope you can attend
at least a few of the meetings.
All of the meetings will be held at the TRW building in Reston, VA. It's conveniently located right off the Dulles Toll Road (Rt. 267).
Directions are given at the bottom of this announcement. We'll serve a light dinner just before each talk. Dinner starts at 6 p.m. and
the speaker usually starts around 6:45 p.m. Do RSVP to me at fseelig@mitre.org or call at (703) 883-3223 so that I can get a head
count for our dinner arrangements. Dinner is optional, but it's free.
If you're not a member, you may wish to consider joining the IEEE. It has an exceptionally good set of monthly journals and
magazines that will keep you current on new technologies and trends in the ever-growing field of communications, modulation,
coding, and networking. Come to at least one of our monthly meetings to see if this group is right for you. We'll have information
you need if you want to join IEEE.
Title: The XM Radio Satellite System
Date: Tuesday, April 30, 2002
Location: TRW, Reston, VA. Corner of Sunset Hills Rd and Reston Town Parkway
Abstract: XM Radio provides 100 channels of CD-quality music, news, and sports channels across the entire United States.
It's been in service for a year. This talk will give a brief overview of the technical aspects of the system, including satellite coverage,
repeater locations in urban areas, receiver design, and cost and regulatory aspects. Brian will demonstrate XM Radio's music quality
in a demonstation at the end of his talk
Speaker: Brian Johnson, XM Radio systems engineering dept, Washington, DC
Speaker Bio: Brian received his BSEE from Virginia Tech and MSEE from George Mason University. Brian worked for 12 years
with Stanford Telecommunications, Reston, VA on a variety of NASA and FAA projects, including STARS, AMASS, ASTA, and ASR
radars. He's been with XM Radio since 2000, where he troubleshoots urban repeater site locations. He's always been musically
inclined, so he hangs out with the musicians and disc jockeys that visit XM as well as with his engineering team.
Speaker: Mike Vertal, VP of Engineering, Wireless Matrix USA, Reston, VA
Title: Real-World Experience with IEEE 802.11b Wireless LAN, and 802.11b Customization
Date: Tuesday, May 28, 2002
Location: TRW, Reston, VA. Corner of Sunset Hills Rd and Reston Town Parkway
Abstract: Wireless Matrix, formerly Norcom Networks, has been a pioneer in the use of industrial messaging using the new
IEEE 802.11 wireless local area network (LAN) technology. Its Mobile Base Station is a truck-top device the diameter of a pizza that
has an L-band geostationary satellite communications transceiver, a 900 MHz terrestrial wireless data network transceiver, and an
802.11 WLAN transceiver card at 2.4 GHz. It's used to communicate with a repairman at service calls in homes and businesses.
The 802.11 WLAN in the serviceman's ruggedized laptop must be battery conservative, so Wireless Matrix worked with Cisco and
Itronix to allow the 802.11 card to have a "wake-on-LAN" command that would only wake the laptop if an incoming alert message
was received. Mike will discuss this process, as well as give real-world performance perspectives on 802.11b.
Speaker Bio: Mike Vertal received his BSEE from Case Western University, Cleveland, OH. Mike has been with Wireless Matrix
USA since it was founded ten years ago.
Speaker: Bijan Jabbari, Professor, George Mason University Electrical and Computer Engineering (ECE) Dept.
Title: Project SOPRANO: Self-Organizing Packet Radio Ad-Hoc Networks with Overlay
Date: Tuesday, June 25, 2002, 6:00 p.m.
Abstract: Unlike the traditional cellular systems, in order to address wireless Internet services efficient and high capacity
packet radio technology in the form of multi-hop with features like self organizing and low power are needed while dealing with the
same problems of interference, multi-path fading and limited bandwidth. This presentation will provide an overview of the project
SOPRANO (Self-Organized Packet Radio Ad hoc Networks with Overlay) and its application to high data rate wireless Internet. We
will discuss aspects such as capacity enhancement and ways to achieve the maximum throughput, self-organization, resource
allocation, and adaptive routing, We will show how coordination among layers enable significant improvements in capacity and
quality of service.
Speaker Bio: Bijan Jabbari received the Ph.D. degree from Stanford University, Stanford, California, in 1981, in electrical
engineering. He has held positions with Hewlett Packard, Southern Illinois University Satellite Business Systems, and M/A-COM
Telecommunications. In 1988, he joined the faculty of the department of electrical and computer engineering at George Mason
University where he is now a professor. He is also an affiliated faculty with ENST- Paris, France. He is Editor for Wireless Multiple
Access for the IEEE Transactions on Communications and is on the editorial board of Proceedings of the IEEE and other journals.
He has served as guest editor for several IEEE publications. He is a coeditor of recent books on Multiaccess, Mobility and Teletraffic
(Kluwer Publishing, Vol. I, and IV through VI) and continues research on multiaccess and wireless communications and Internet and
traffic theory. He is the past Chairman of the IEEE Communications Society technical committee on Communications Switching and
Routing. In 1999, he founded the Advanced Internet Laboratory at George Mason University, through industry research grants and
support of the Internet industry. He received the IEEE Millennium Medal in 2000. Dr. Jabbari is on the advisory board of several
communications companies and serves as a consultant to government and industry.
Speaker: Mr. Roger Flaherty
Title: NASA's Near-Earth Communications Links for Hubble, Chandra, EOS, TDRS, Space Shuttle and ISS Support

the toll booth.
Once you're there, go into the main lobby. The receptionist will direct you to the conference room, which is just off the lobby.
The conference room has a great Audio-Visual staff. You can use a video port to hook up to your laptop. Anything visible to your
laptop's screen can be broadcast out the video port. An overhead color projector displays your graphics to a large screen in the front
of the room. If you want to show overhead transparencies there is an overhead projector.
