HPWREN Aids Firefighters on Palomar Mountain
For the past four years, astronomers at the California Institute of Technology's Palomar Observatory in Southern California have been using the High Performance Wireless Research and Education Network (HPWREN) as the data transfer cyberinfrastructure to further our understanding of the universe. During the recent firestorms in southern California HPWREN was used at the observatory for a much more down-to-earth purpose -- providing vital emergency communications when all other resources were cut off.
