Mission Statement
The University of Hawaii Center for Advanced
Communications is a multidisciplinary research
center bringing together researchers from diverse
areas to work together on advanced communication
systems (wireless).

• Joint collaborative research among members of the
  Center and with external researchers from
  industry and academia.
• Provide students with a rich and diversified
  education to prepare them for careers in the
  telecommunications industry and academia.
• Encourage industrial interactions, promotion of
  entrepreneurial activities, and providing
  technical leadership and expertise to the
  University and State of Hawaii.

Broadband Communications
Within a decade, most people in developed
countries will have access to Internet
connections that are tens if not hundreds of
times faster than the ones in common use today.
Scientific American, Oct. 99.

• Cable Consumer, coaxial cable to home.
• Copper Digital Subscriber Line (DSL), use
  existing phone network.
• Fiber Expensive to home, highest available
  bandwidth.
• Satellites Low earth orbit systems, satellite
  deployment costs high.
• Wireless Local Multi-point Distributed Systems
  (LMDS), offer multiple services, easily
  deployable, line-of-sight communications.

Broadband Wireless Communications

• Wireless cable MMDS now deployed in many parts of
  the world.
• New multi-point systems such as LMDS (28GHz
  carrier frequency) (1.3GHz total bandwidth)
  offer multiple services with same network.
• Deployment can be phased to cover desired
  customer base.
• LMDS data rates will serve business access
  needs.
• Lower cost access than fiber to the home or
  office.
• Short wavelengths imply small antenna and circuit
  size resulting in more compact modules for mobile
  communications.
• Line-of-sight communications useful for satellite
  cross-links and secure communications.

Center Benefits to the State of Hawaii
How will the Center benefit development of
wireless communication industry in Hawaii?

• Center will get funding from Federal government,
  State government, and industry to work on
  wireless communication research. Research will
  generate knowledge necessary to help develop
  future generation wireless communication
  systems.
• Center will create industrial affiliates program
  where member companies work with Center to work
  on research, education, and development of
  wireless communication technology.
• Center will create a multidisciplinary education
  program. Students that graduate from program
  will provide backbone of work force for wireless
  communication industry in Hawaii.
• Center will take advantage of contacts and
  location in Pacific rim to attract leading
  researchers and top quality students from Pacific
  rim countries.

12
Why an Advanced Communication Center inHawaii?

• Personnel diversified members with expertise in
  a broad range of wireless communications
  technology.
• Existing backbone infrastructure Optical fiber
  backbone in place can work well with local
  wireless system for broadband access for
  consumers and business.
• Geographic location Pacific Rim location can
  bring wireless technologies from Asia (Japan)
  and North America (USA) together.
• Timing Industry time-scale is short (need to act
  now).

13
What does the Center need?

• Personnel (University support)
• Director world-class researcher in wireless
  communications.
• Faculty need faculty to bridge gaps in expertise
  (devices, signal processing, computer software
  and hardware).
• Staff
• Continued support from government and industry.
• Laboratory infrastructure upgrades and equipment
