HPWREN receives new award from the National Science Foundation
The National Science Foundation (NSF) recently announced a four-year
award as a follow-up to the currently NSF-funded High Performance
Wireless and Research Network (HPWREN), which has been created and
expanded over the past four years. This new award, in response to
the Information Technology Reseach solicitation, has a strong
research agenda on quality of service, but is also viewed a followon
to the existing HPWREN award, and is titled "Integration and Analysis
of Reliable Networking for Remote Science, Education, and First

HPWREN's First Night Time Incident Response Deployment
On Tuesday, July 13, 2004 (at 4:45pm), the HPWREN staff received a
request for a data communications setup from the San Diego California
Department of Forestry and Fire Protection (CDF) Emergency Command
Center Chief. This ad-hoc connectivity would support firefighters
working to control the Mataguay Fire. This was HPWREN's first night
time ad-hoc deployment for incident communications.

HPWREN increases network robustness with a third FCC-licensed link
A new 6GHz-band licensed link beween Mt. Woodson and the Cuyamaca
mountains has replaced an earlier 5.8GHz license-exempt one. This
now extends HPWREN licensed connectivity from the coast to the
mountains in the San Diego region.

HPWREN and the Palomar Observatory - Lifting the Veil
on the Universe
One of the universe's most mysterious and explosive events is the
phenomenon known to astronomers as a Gamma-Ray Burst (GRB). They
are briefly bright enough to be visible billions of light years
away. They are difficult to study as they are short lived and take
place at seemingly random locations and times. To achieve an
understanding of what exactly a GRB is and why they occur, astronomers
need to act quickly to pin down their exact location and observe
them while they are exploding.

HPWREN Collaborates with the California Wolf Center
The recently installed California Wolf Center HPWREN connection,
as well as the new web-based digital camera, will allow the Center
to more broadly share valuable scientific and educational resources.
This near real-time feed showing gray wolf interactions posted on
publicly available web pages will help satisfy a critical component
of the Wolf Center's mission.
