Departmental News
CWT's Dr. Charles Bostian was named Virginia Tech Scholar of the Week by the Office of the Vice President for Research for February 20-24.
CWT's Dr. Charles Bostian, Alumni Distinguished Professor in the Bradley Department of Electrical and Computer Engineering, presented a special seminar for faculty titled "An Opportunity to Build a Large-Scale Cognitive Wireless Network" on Tuesday, Jan. 24, from 3 to 5 p.m. in room 219 of the War Memorial Gym.
This special presentation was related to an anticipated funding opportunity involving a large (>1000 nodes) cognitive wireless network on the VT campus.
Dr. Bostian described his group's current work in cognitive electronics and invited potential collaborators to join a proposal writing team.
The seminar was sponsored by the Institute for Critical Technology and Applied Science.
For more information on Cognitive Radio, and some suggested reading, please see CWT's Cognitive Radio web site.
Tom Martin, CWT affiliated faculty member, has received a
NSF CAREER Award titled "E-Textile-based Wearable Computing for Sensing User Motions".
The research aspect of the grant involves sensing the shape of
an e-textile garment, the wearer's motions, and the dynamic location of
sensors. If successful, this work will enable applications in physical
therapy, human-computer interfaces, and in-the-field bio mechanical
measurement. CAREER awards are one of the most prestigious endorsements
that an assistant professor can receive.
Two CWT alumni and a CWT PhD candidate presented papers at the
IEEE Wireless and Networking Conference, 2005.
- Tianmin Mo (PhD EE 2005 candidate) presented "PHY04-1: A Throughput Optimization and Transmitter Power Saving Algorithm for IEEE 802.11b Links",
co-written with CWT's Dr. Bostian, in the 802.11 MAC1 session
- Shyamal Ramachandran (MS EE 2004, currently with Mesh Networks) presented "NET11-4: A Link Adaptation Algorithm for IEEE 802.16",
co-written with CWT's Dr. Bostian and Dr. Midkiff, in the Wireless Metropolitan Area Networks session
- Nathan Ramasarma (MS EE 2002, currently with Bechtel Telecommunications, USA) presented "NET20-2: GPRS Measurement Methodologies and Performance Characterization for the Railway Environment",
co-written with Dirk Michel (Bechtel Telecommunication, UK), in the Experimental Evaluations session
- CWT's T. Rondeau presented
"Cognitive Radios with Genetic Algorithms: Intellient Control of Software Defined Radios" on 11/18 at the
SDR'04 conference (track 1.5) in Arizona.
Coauthored by B. Le, C. Bostian, and C. Rieser. A slide of Rondeau demonstrating the equipment is available
here; contact CWT for print-quality versions or further information.
CWT Director Dr. George Morgan has been named "Virginia Tech Researcher of the Week" for June 14-20, 2004.
The text of the announcement reads:
"The Office of the Vice Provost for Research recognizes Center for Wireless Telecommunications Director George Morgan for interdisciplinary research evaluating the financial viability of broadband wireless in rural communities."
CWT members Charles Bostian and Tom Martin received Teaching
Certificates from the Bradley Department of Electrical and Computer
Engineering. Tim Pratt received the Dean's Award for Service. Tom Martin
is also the 2004 winner of the Dean's Award for Teaching
Innovations.
Congratulations to these CWT faculty members on their well-deserved
recognition.
CWT would like to congratulate the following students, who have
graduated from Virginia Tech at the end of Fall or early this Spring,
and would like to thank them for their service to CWT.
- Suem Ping Loo,
- Shyamal Ramachandran,
- Vana Venkataramani, and
- Vani Viswanathan.
CWT faculty members Dennis Sweeney (CO-PI) and Bill Carstensen
(PI), of Geography, were awarded an $80k continuation on their
grant "A GIS Evaluation of Geographic Effects on Signal Propagation at
150 - 900 MHz. Frequencies" funded by Lockheed Martin Corporation.
CWT co-founder Dr. Charles Bostian, a professor of electrical and computer
engineering in the College of Engineering at Virginia Tech, was
appointed an Alumni Distinguished Professor by the university's Board of
Visitors.
The rank of Alumni Distinguished Professor is reserved for select
faculty who have made long-term and outstanding contributions to the
instructional program of the university, thus influencing the lives of
generations of alumni.

CWT director Dr. George Morgan attended the annual IOC Wireless
Symposium, held October 8-10 in Seattle. The symposium was sponsored by
the National Telecommunications Cooperative Association (NTCA).
His presentation "Why Wi-Fi? Will WiMax?" addressed the question of why
the popularity of Wi-Fi has grown, while other broadband technologies
have seen a decline in popularity.
Joseph Noronha attended the semi-annual Vehicular Technology Conference,
held October 6-9 in Orlando. The conference was sponsored by the
Institute of Electrical and Electronics Engineers (IEEE).
He presented a paper titled "A Parametric Study of Time-Domain
Characteristics of Possible UWB Antenna Architectures," which he
co-wrote with Stanislav Licul, William A. Davis, Dennis G. Sweeney,
Christopher R. Anderson, and Timothy M. Bielawa. The paper attempted to
define the potential characteristics of an antenna that could "exploit
the inherent advantages in pulsed communication systems,
specifically...ultra-wideband."
- The Center for Wireless Telecommunications has been awarded a
$150,000 sponsored project by Boeing to conduct a CDMA Technical
Feasibility Study. Dr. Charles Bostian is the principal investigator on
the project and is joined by faculty members, Dr. Liching Sung, Dr.
Scott Midkiff, Dr. Tim Pratt and Dr. Brian Woerner. The study will
investigate CDMA technologies for the mobile and fixed communications
market. The goal is to investigate and prototype a CDMA two-way terminal
for point-to-point, mesh and star networks. The project involves an
interdisciplinary effort that will look at regulatory and interference
issues, terminal characteristics, networking issues and modem design.
- The students in the cross-disciplinary course Commercializing
Network Technologies, taught by CWT Director and Finance Professor
Dr. George Morgan and CWT faculty member and Associate Professor of
Economics Dr. Sheryl Ball, benefited from interacting with several guest
speakers. IREAN Research Fellows
gained insights from a panoply of speakers whose expertise covered
aerospace, venture capital, investment banking, corporate research
parks, intellectual property, national information technology policy,
international regulation, and high technology marketing. Guest speakers
have included:
- Chuck Box, Business Development, Satellite Applications Center, Boeing,
- John Higginbotham, Founder and Chairman, SpaceVest,

Young Investigator Program for 2003. In announcing the awards, the ONR
called the recipients "the best and brightest young academic researchers
in this country." For more information, visit this
