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 Wide range of services ranging from
  Local Multi-point Distributed Systems (LMDS) to
  mobile broadband access.

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.
• Personal communication systems.
• Mobile, wireless network architectures.
• Hand held devices moving from voice to
  integrated services.
• Interoperability seamless interconnection to the
  internet.

Infrastructure (Partnership)

• Center Personnel
• Director (need to hire leader in
  telecommunications with academic, industrial and
  administrative experience)
• Members
• Existing members (support and retention)
• New members (augment expertise and bridge
  technologies)
• UH Administration (positions, infrastructure,
  budget)
• State Government (financial support)
• Industrial Partners (annual fees)
• Each partner to have members as focal contacts.
• Joint work with focal contacts on research
  projects.
• Federal Government (Joint collaborative
  research with members, other institutions, and
  industry)

12
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).
• Ad Hoc Wireless Networks
• Network control and management
• Channel and source coding for wireless
  communications
• Signal processing algorithms
• Applications (broadband access everywhere)
  commercial and military

Education

• Attract quality students and researchers (reverse
  brain drain).
• Provide multidisciplinary education to prepare
  students for careers in telecommunications.
• Fundamental and cutting edge classes.
• Research instruction and experience.
• Information Technology Alliance (Engineering,
  Computer Science, Business, Education)
• Work to establish educational programs with
  industry (life-long learning).
• Coop programs (undergraduate and graduate
  students).
• Distance learning programs.

15
Industrial RelationshipsA key to Center
development and growth is close working
relationships with industry. (Industrial
Partners)

• Startup companies
• Adtech started by UH EE Professors.
• Verifone started by UH EE graduate.
• EE Professors starting high tech companies.
• Attracting companies to Hawaii (Uniden).
• Relationships with local companies Adtech, GTE
  Hawaiian Tel, Oceanic Cable, military.
• Special relationships with TRW and Boeing.
• Other industrial ties ATT, Fujitsu,
  Hewlett-Packard, Hughes, LSI Logic, Microsoft,
  Motorola, Sony, Sun Microsystems, Texas
  Instruments, Xilinx

Center Benefits to the State of Hawaii
A well funded Center with quality personnel will
provide

• a significant boost in federal and industry
  funding to the University of Hawaii.
• a large increase in students who will be well
  prepared for careers in telecommunications.
• technical knowledge to the State for development
  of a telecommunications industry.
• an increase in skilled technical people and high
  technology industry that will come to Hawaii.
• an increase in the number of high technology
  conferences and workshops held in Hawaii.

17
Why develop the Hawaii Center for Advanced
Communications?

• Personnel diversified members with expertise in
  a broad range of 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.
• State and industry interest Diversification of
  Hawaiian economy.
• Timing Industry time-scale is short (need to act
  now).
