Department of Telecommunication and Signal
Processing

• The convergence of voice, data, and video -- in
  transmission and processing -- has created a
  demand for talented and well educated engineers.
• We, in the Department of Telecommunication and
  Signal Processing, provide the education of these
  engineers.

Academic Programs

• Undergraduate program
• Telecommunication
• Computer Engineering
• Signal Processing
• Internet Systems
• Graduate program
• Doctoral research in all programs

8
Driving Forces

• The increase in Internet traffic
• The increase in Mobile traffic
• The increase in the number of Internet
  applications
• This research is quite simply fun
• It is also challenging
• The return is great

In the beginning --It was easy
Telephone Network
10
Then we started to do more
IP ATM Internet MPLS
11
Factoids

• In the future Integrated Networks
• Large variety of network traffic
• Orders of magnitudes of different time scales
• Quality of Service requirements
• Mobility
• New and diverse applications

12
Growth and Revenue Forecast

• Explosive growth in IP traffic.
• Wireless traffic will continue to grow.
• Voice and connection-based data services will
  continue to generate the bulk of service provider
  revenue over the next three years.

13
Worldwide Wireless Research ForumWWRF

• Main goal Developing and maintaining a
  consistent Future Generation system vision among
  the wireless industry and leading universities
  who start looking beyond 3G
• Recommendations for future research priorities
• Open invitation to the research community to
  present and align their visions in order to get
  critical mass
