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/

Tribal Digital Village project

• Native American activity building up on HPWREN
• Funded by Hewlett Packard
• Awarded to the Southern California Tribal
  Chairmens Association
• HPWREN is collaborator, and not the service
  provider
• Objective of a utility architected and operated
  by Native Americans
