high performance wireless research and education network
Network architecture
• high performance backbone network• commercially available 45Mbps duplex point-to-point radios• backbone nodes at “quality” locations, including UPS• fairly large antennas (8’, 6’, or 4’)• network performance monitors at backbone sites
• high speed access links• commercially available 802.11b radios• some 45Mbps access links• access nodes at individual sites• point-to-point or point-to-multipoint• small (~2’ X ~3’) grid antennas• some sites include local performance monitors
• network statistics available at http://stat.hpwren.ucsd.edu/
