administrative staff.
Why Northwestern University Chose RADVISION:
RADVISION’s expertise and experience with large educational networks and multi-location businesses for
videoconferencing was a key factor in Northwestern University’s decision. The RADVISION products also
offered a low entry cost for the university’s videoconferencing needs while providing a complete line of
products.
According to Northwestern University’s Amiot, RADVISION’s ability to provide excellent product support
and access to new and emerging features were among factors in the RADVISION selection. The
RADVISION solution is highly scaleable and will be able to accommodate increases in demand and traffic
for the videoconferencing systems in the future. He also adds, “Most importantly (in the decision) was
RADVISION’s involvement with Internet 2 and other universities and organizations around the world.
RADVISION has adapted its product evolution to meets the needs of the educational community.”
Introduction:
Northwestern University is one of the country’s leading private research universities with campuses in
Evanston, Illinois, and Chicago. The university employs approximately 2,100 full-time faculty serving more
than 13,600 full-time students (including 7,700 undergraduates).
2. Northwestern University has always distinguished itself as an ambitious institution, combining innovative
teaching and pioneering research in a collaborative environment. It strives to be an institution that
encourages innovation and the integration of experience across many fields. To keep its position as a
forerunner in higher education, the university turned to RADVISION for its leadership and experience in the
videoconferencing space. RADVISION is a leading provider of products and technology for real-time voice,
video, and data communications over packet networks.

Northwestern University then selected RADVISION’s line of quality videoconferencing products. These
products include:
• viaIP Multipoint Conferencing Unit (MCU) has a high density and proven performance and gives
Northwestern University the ability to conduct conferences for voice, video and data between three
or more endpoints.
• Data Collaboration Server (DCS) is a dynamic and scalable solution for data collaboration. The
DCS allows real-time sharing of files and applications like Microsoft PowerPoint and Excel.
• Enhanced Communication Server (ECS) is an advanced call management application with
advanced H.323 gatekeeper technology that can set policies and control network resources, such as
bandwidth usage and traffic direction, to ensure optimal network performance.
3. • viaIP Gateway is a high-performance, scalable and cost effective solution for providing the ability
to connect ISDN-based H.320 systems to IP-based H.323 systems and endpoints. It seamlessly
translates between H.320 and H.323 networks to relay audio and video streams from one network to
another.
Results:
The installation of the RADVISION system gives Northwestern University the enhanced learning
environment needed to keep its foothold as a leader in the higher education space. Videoconferencing allows
distance learning, faculty and student collaboration, and the exchange of ideas between its two campuses. It
has also opened the door to a plethora of information and opportunities with other universities and businesses
globally.
“There are many collaborations between departments and schools and with other institutes and businesses,”
Amiot said. “For example, although Northwestern University's medical and undergraduate campuses are
only eleven miles apart, this distance really impedes communication, interaction, and collaboration. Our
ability to readily engage medical faculty in undergraduate teaching has become much easier, due to the
presence of videoconferencing. Similarly, we have appreciably enhanced two-campus faculty interaction for
seminars and research meetings.”
Videoconferencing will also reduce the university’s cost in travel expenses. “It is hard to attach a figure to
the savings,” he said. “Will the interactive meetings replace travel or would they just be meetings that
wouldn’t happen? Either way, the collaboration is beneficial.”
