Wireless Trondheim
as a research area
• TrT Access (or ”Broadband commons”)
– A wireless network in Trondheim city for ”everyone” (initial user groups
covers: NTNU, The County, The City administration Trondheim, The
Electric Power Company of the town and Adressa the dominant regional
newspaper). This gives a potential aggregated number of users in the range
40 to 50 000 (includes all students at the univ. and all high school students).
• TrT Network lab
– A full-sized outdoor lab suitable for testing new networking technologies.
• TrT Service Lab
– A lab for mobile service development and testing.

• Physical Infra structure
– Broadbands connections (Gb/s, fiber og Cat5+ kabel).
• NB: TrT Network lab has its own communincation links
(not shared by TrT Access)
– Power Supply,
– Mounting facilities and (agreements with property owners!)
– Climatic safe housing for experimental equipment, etc.
• Preinstalled servers and experimental equipment
– Measuring equipment
– Programmable routers and access points
– Servers to facilitate research, e.g a location server

Novel radio systems and technologies
• Antenna systems and implementation of MIMO ( Multiple input/output systems)
• Advanced modulation methods/systems
• Product design, cost efficient esthetical design and integration with other equipment
along roads and streets.

Novel systems solutions in wireless access networks
• Seamless handover between heterogeneous systems.
• Prioritised handling of emergency calls (and other important traffic) - testing of
principles to be utilised for crisis management.
• Pilot testing of new principles to ensure quality of service,, information security and
correct payment/charging..
• Principles of location determination and navigation, possibilities of comparing
technologies..
TrT Network Lab as a research area
for Intelligent Transport Systems
PROJECT EXAMPLES:
• Testing of the technology platform for ITS (6 th. framework project “Cooperative
Vehicle-Infrastructure System project”, ref. IST-2004-2.4.12-eSafety-Cooperative
Systems for Road Transport)
