The High Performance Wireless Research and Education Network (HPWREN), a University of California San Diego partnership project led by the San Diego Supercomputer Center and the Scripps Institution of Oceanography's Institute of Geophysics and Planetary Physics, supports Internet-data applications in the research, education, and public safety realms.

HPWREN functions as a collaborative, Internet-connected cyberinfrastructure. The project supports a high-bandwidth wireless backbone and access data network in San Diego, Riverside, and Imperial counties in areas that are typically not well-served by other technologies to reach the Internet. This includes backbone locations, typically sited on mountain tops, to connect often hard-to-reach areas in the remote Southern California back country.

The network supports a wide range of network application requirements, ranging from the high-volume astronomical data generated by the Palomar Observatory, to a steady output of continuous, low-volume traffic from many devices such as earthquake and other environment-observing sensors, which deliver real-time data. HPWREN includes permanent sites as well as those created temporarily and on short notice, such as firefighter Incident Command Posts (ICPs). HPWREN saw use in several of the major wild fires to hit San Diego County across many years.

The network spans from San Clemente Island in the Pacific Ocean, via the southern California coast to the inland valleys, east toward the mountain elevations of almost 9,000 feet, and the remote desert, reaching almost to the Arizona border. The network's longest link is 72 miles in distance, from the San Diego Supercomputer Center to San Clemente Island.

Augmented camera capabilities created by collaboration between multiple universities and private industry in support of fire watch activities

November 9, 2017

HPWREN, in collaboration with San Diego Gas and Electric (SDG&E), as well as the University of Nevada Reno (UNR), has begun to add cameras with optical zoom capability to its vast network of environment-observing cameras.

HPWREN Time Lapse Video - Dec 7, 2017 Lilac Fire in San Diego County multi-camera time lapse animation

HPWREN Time Lapse or

Live Stream Videos

Fires, weather conditions, flooding, and other public safety conditions are scenarios where real-time sensor data distributions can become important aspects for situational awareness. HPWREN can now provide live feeds from most of its cameras, in addition to the post-processed videos shown at:

This 4-camera time-lapse video starts at 9am on December 7, before the Lilac Fire ignition closer to noon. Significant dust blowing can be seen before the fire starts. The animation continues until about 6am on December 8, and is sped up about 1,000 times at 17 fps from once-per-minute collected images.
