UCSD Telecommunications Works with HPWREN for Wireless Connectivity at May's CENIC Conference
The HPWREN team collaborated with UCSD Telecommunications to provide the recent Corporation for Education Network Initiatives in California (CENIC) conference with wireless connectivity. The connection provided a temporary two-day link from SDSC to Mount Soledad to Paradise Point, which was the location of this year's CENIC 2001 – A Network Odyssey.
Several HPWREN collaborators also presented at the conference, focusing their talks on the range of applications that benefit from wireless connectivity. Presenters included Hans-Werner Braun, Todd Hansen, Frank Vernon, Sedra Shapiro, and Paul Etzel.
The HPWREN grid antenna atop San Diego Supercomputer Center pointed to a tripod-mounted yagi antenna on Mount Soledad, approximately 3.1 miles away. From there, another yagi antenna pointed to the conference facilities at Paradise Point, approximately 4.5 miles from Soledad.
The radios used in the demonstration utilized direct sequence spread spectrum technology at 2.4GHz, and provided an Ethernet bridging functionality. Both the grid and yagi antennas were also equipped with power amplifiers.
Perhaps the most interesting aspect of the CENIC 2001 demonstration was the rapid deployment. That is, the decision to deploy this wireless network was made less than 24 hours prior to installation; however, UCSD Telecommunications worked diligently with the HPWREN team to ensure successful implementation.
