Research Overview
Major focus is on high-performance wireless
networks. Transmission technology for networks
are millimeter-wave frequencies (30-300 GHz)
which provides broadband rates up to 5 gigabits
per second.

• Millimeter-wave networks
• Ideal for indoor wireless LANs, line of sight
  (LOS)
• Shorter wavelengths imply smaller antenna and
  circuit dimensions
• Broadband applications (interactive multimedia)
• Mobile Wireless Networks
• Network control and management
• Channel and source coding for wireless
  communications
• Signal processing algorithms
• Applications (broadband access everywhere)
  commercial and military
