New HPWREN Link Redundancy Significantly Increases Network Robustness
After a year of planning and preparation, the southern loop of HPWREN wireless connectivity is now complete. "The completion of this connection significantly increases the robustness of the network, in case of node outages and link weaknesses - such as when we are under interference situations," explains Hans-Werner Braun, HPWREN PI. "It also provides needed extra bandwidth for demanding applications, such as the astronomy observatories that HPWREN connects."

Earlier this month, the U.S. Navy Deep Submergence Unit (USN-DSU) brought their ship, the Kellie Chouest, as well as the Remotely Operated Vehicle (ROV) Scorpio, to the waters off Scripps pier. Their mission: to locate and dive the site of SeaLab II, a USN/SIO undersea habitat that operated in August-October 1965. This would be the first return to the site since the habitat was pulled up. This cruise was a regularly scheduled training exercise for the USN-DSU personnel; however, several guests (including UCSD faculty and staff) were able to join the crew for a day-long excursion.

Local Agencies Team with Researchers for Crisis Management Exercise
Imagine this.

A truck hauling hazardous chemicals crashes in an urban environment, causing a poisonous plume to penetrate the area. Multiple government agencies ranging from the Police Department to the Department of Transportation are called onto the scene. All agencies involved have capabilities to dispatch information to one another via voice systems; however, the ability to transfer descriptive maps and images between the agencies is not possible.

This scenario is not uncommon in urban areas, and a group of local San Diego government agencies recently collaborated with Space and Naval Warfare Systems Center San Diego (SSC San Diego) and HPWREN researchers to demonstrate the feasibility of incorporating real-time images and maps into such incident management situations.

HPWREN Provides Seismologists with Improved Seismic Data Collection and Distribution Methods
Today's seismologists can view activity from the earth's interior as it occurs - enabling scientists from around the world to gain extensive insight into the often elusive patterns of seismic waves. However, current seismic research techniques only allow researchers to look at rather broad datasets, which is not always enough information to determine the exact cause and effect of an earthquake.

Frank Vernon, a researcher at SIO's Institute of Geophysics and Planetary Physics (IGPP), is taking real-time data collection and distribution one step farther with HPWREN.

Mount Laguna Observatory December 13, 2000
Mount Laguna Observatory Astronomers Benefit from HPWREN
Situated at an elevation of about 6100 feet, San Diego State University's Mount Laguna Observatory (MLO) is 35 air miles from the SDSU campus (on a direct line of sight) and 45 miles from metropolitan San Diego. With telescopes that achieve maximum resolution, an astronomer at the observatory typically generates 200 images on a long winter night. In order to transfer the data from Mount Laguna to on-campus facilities, digital audio tapes (DATs) are currently used. However, high-speed Internet access provided by UC San Diego's HPWREN project will soon open up a world of opportunities for MLO astronomers.

HPWREN High Speed Backbone November 29, 2000
HPWREN Backbone Nears Completion
Significant progress has been made within the past few weeks toward the NSF-funded High Performance Wireless Research and Education Network backbone installation in remote San Diego county. Specifically, a 45Mbps full-duplex wireless backbone is being established between the San Diego coastline and the county's eastern mountains, which exceed 6000 feet in height.

The initial high-speed application will be the Mount Laguna Observatory, which is operated jointly by San Diego State University Astronomy Department and the University of Illinois at Urbana-Champaign. Another immediate application includes earthquake sensors deployed by UCSD's Scripps Institution of Oceanography.

The HPWREN backbone consists of four nodes: SDSC, Mount Woodson, Cuyamaca Mountains, and Stephenson Peak.

HPWREN Backbone Installation Begins November 13, 2000:
Backbone Installation Begins for UC San Diego's High Performance Wireless Research and Education Network
Though brisk temperatures and harsh winds stalled the backbone installation for a few days, significant progress is being made this week. Two antennas have now been mounted at Stephenson Peak, one pointing toward SDSU's Mount Laguna Observatory (MLO) and another toward Cuyamaca Mountains; the heliax cables will soon be attached as well. Meanwhile, installation of the MLO antenna has also been completed. Special thanks to Glen Offield and Bud Hale for their hard work on the towers!
