HPWREN Adds Another Node to its 45 Mbps Backbone: Toro Peak Antennas Provide Remote Scientists and Educators with High-Speed Network Connectivity
Last month, the HPWREN team completed a 70-kilometer link using 45 Mbps radios between Toro Peak and Mount Laguna to provide Internet connectivity to Toro Peak and beyond. Not only does the Toro node allow field seismologists and ecologists access to a high-speed network, but it will also provide educators on the rural Santa Rosa Native American Reservation with a broadband connection to the Internet.

UCSD Department of Structural Engineering Partners with HPWREN for Connectivity at Camp Elliott Field Laboratory: Broadband Installation Supports CalTrans and NSF NEES Research
The HPWREN team recently worked with UCSD Department of Structural Engineering field researchers for an installation at Camp Elliott. The facility, which is located about eight miles east of UCSD, is currently being used by the engineering researchers as a seismic test facility and is now linked to the 2.4 Ghz portion of HPWREN.

HPWREN Study Examines Impact of Broadband Connectivity Upon Ecological Field Research
The HPWREN team recently completed a social science study focused on the diffusion of the network within the 4500-acre Santa Margarita Ecological Reserve (SMER). Recently deployed sensors and high-resolution cameras allow researchers from throughout the world to conduct their studies at SMER≠and receive their sensor and camera data via the Internet. That is, the collected ecological data travels via the Internet (originating with the HPWREN connection) from dataloggers and cameras in the field directly to the researcherís computer.

HPWREN Users Workshop Focuses on Current and Future Network Applications
On May 18, HPWREN users ranging from astronomers to educators met to discuss their current uses of the network and how they plan to utilize the connectivity for future applications as well. The meeting was hosted by San Diego State University's Mount Laguna Observatory director Paul Etzel, who also spoke at the workshop. Additional speakers included HPWREN PI Hans-Werner Braun, HPWREN co-PI Frank Vernon, Greg Aldering from the Palomar Observatory, Dan Cayan from the Scripps Institution of Oceanography, Mike Peralta from the Tribal Digital Village Network, and Pablo Bryant from the SDSU Santa Margarita Ecological Reserve.

Wireless Connectivity Enables Sensors on Coronado Bridge
On May 15, the HPWREN and ROADNet teams participated in a UCSD activity that demonstrated an ad-hoc and temporary multi-media installation of seismic and visual instrumentation at the Coronado Bridge. The installation provided wireless IP access, using off-the-shelf 802.11b technology, from the bridge to the UCSD campus, where participants examined and discussed the feasibility of a permanent networked monitoring system of this type. The system would specifically be used for UCSD research aimed at the crisis management community.

HPWREN Collaborates with UCSD Academic Computing Services for Wireless Connectivity at 2002 CENIC Conference
For the second year in a row, the HPWREN team worked with UCSD Telecommunications to provide the Corporation for Education Network Initiatives in California (CENIC) annual conference with wireless connectivity. Additional collaborators in the activity included UCSD Media Services and Cisco Systems.

SDSU Collaborates with HPWREN to Test High Performance Wireless Connection with Airplane
San Diego State University's Global Change Research Group (GCRG) and Field Station Programs recently collaborated with HPWREN to develop and test a high performance data communications link between a research airplane and a ground station. Rommel Zulueta, a doctoral student in the GCRG's program as well as the airplane pilot; along with Pablo Bryant, research technologist from SDSU's Field Station Programs; and HPWREN's Todd Hansen and Hans-Werner Braun ran their first flight test in a San Diego inland area on April 9.

Swiss Botanist Studies Southern California Wildlife Using HPWREN-Connected SMER Camera
When Rolf Baumberger, a biology researcher at the University of Zurich in Switzerland, studies southern California wildlife, he no longer has to buy a plane ticket to San Diego. Instead, he logs onto a computer. Together with Santa Margarita Ecological Reserve Director Claudia Luke, Education and Outreach Coordinator Adrienne Marriott, and Student Conservation Association Intern Maria Wiehe, Baumberger will use HPWREN's camera stations at the Santa Margarita Ecological Reserve to determine the role of hummingbirds, bees, and moths in the pollination of bush monkey flower, Mimulus aurantiacus.

San Diego Native American Communities Continue Transition from HPWREN to Tribal Digital Village Network
The Southern California Tribal Chairmen's Association (SCTCA) recently completed additional milestones in their efforts to transition HPWREN to their Tribal Digital Village Network (TDVNet), which continues its expansion to reach all 18 San Diego County reservations. Earlier this month, the tribes added another antenna on a Palomar Mountain relay station. This relay, which is often referred to as Cluster 1, connects three Native American tribes to broadband telecommunications - allowing the tribal communities to have the same access to high-speed Internet as their urban counterparts.

Wireless Tests Aboard US Navy Ship Include Exploration of USN/SIO SeaLab II
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.

HPWREN Team Experiments with Small, Low-Power Network Performance Measurement Machines for User Sites
While network measurement machines typically consist of relatively large desktop or rack-mountable computers, the HPWREN team is currently experimenting with a 3"x3"x3" computer that examines the quality of links at user sites. An early deployment includes the Pala Native American Learning Center, which is connected to HPWREN. This machine allows for reachability as well as throughput tests and is available for additional applications, such as weather stations.
