Public Safety Agencies Begin Work on an HPWREN-like System
for Southern California
For more than five years, the HPWREN team has been working with
first responders in the San Diego area to better understand how
high-speed wireless data networking can assist with public safety
aspects in hard-to-reach areas for both persistent and ad-hoc
connections. Now multiple agencies formed a formal consortium to
capitalize on the research findings of HPWREN's work in the public
safety arena and build a high-performance data network.

Prototype Fiber Optic Seismometer
Modern seismometers throughout the world, including those on HPWREN,
rely on electronic displacement transducers to sense motions of an
inertial mass, whenever the earth's surface moves. New advances in
optical fiber technology are providing an alternative to this type
of modern observatory grade seismometer.
