Professor
Peha's research addresses social and policy issues
that are inseparable from the technological evolution
of computer and telecommunications networks. One such
area is wireless systems. The allocation and regulation
of radio spectrum affects the evolution of technology,
possibly determining whether novel services and technologies
will emerge, and the extent of competition, standardization,
and mutual interference.
In the
area of electronic commerce, Professor Peha has investigated
payment system technology and the complexities of
bringing financial services to people without bank
accounts, enforcing tax law on electronic commerce,
protecting privacy, enhancing security, and combating
fraud.
Professor
Peha also does research on integrated-services networks,
which simultaneously carry voice, video, and computer
traffic. This technology blurs the distinction between
telephone networks, cable TV, and the Internet, which
face radically different regulation. The resulting
services, prices, and industry structure depend on
the complex interplay between technology and policy.
Another
critical issue is bringing the benefits of information
technology to everyone. Professor Peha's research
addresses telecommunications issues in developing
countries, like serving rural and low-income areas
with little installed infrastructure. Reaching schools,
community centers, libraries, and health care providers
is also important in both the US and developing countries.
