Distinguished Service Professor, Engineering
and Public Policy and Electrical
and Computer Engineering.
Research in technology public policy issues relevant
to wireless
communications and the development of new telecommunications
infrastructure.

Professor Alex Hills is the founder of Carnegie
Mellon's Wireless Initiative, a research program
which concerns mobile computers and their ability
to have continuous, high speed access to the Internet.
He is also the creator of Wireless
Andrew, Carnegie Mellon's groundbreaking campus
wireless network. Working with colleagues, Professor
Hills has developed a methodology for designing large
scale wireless LANs. He also recently invented a semi-automated
design tool called Rollabout,
which dramatically improves and speeds up the design
process.
In addition, Professor Hills works on technology
and policy issues relevant to establishing new telecommunications
infrastructure in developing and remote areas of the
world. His work with wireless local loop technology,
for example, has shown that it can be extremely cost
effective but that national decision makers must allocate
sufficient radio spectrum to guarantee its feasibility.
