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 with the NSF-funded High Performance Wireless Research and Education Network (HPWREN). The HPWREN team is creating, demonstrating, and evaluating a non-commercial, prototype, high-performance, wide-area, wireless network in San Diego county. Specifically, HPWREN includes a 45Mbps full duplex wireless backbone, using 5.8GHz radios, while the access lines will commonly use inexpensive and off-the-shelf 2.4GHz 802.11 spread spectrum radios.
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.
The NSF-funded network includes additional backbone nodes at UCSD and a number of "hard to reach" areas in San Diego county. The next installation locations for the high speed backbone will include Cuyamaca Mountains, Mount Woodson, and SDSC.
