  1. Wireless, Etc. UW Computing Support MeetingDecember 18, 2002 Terry Gray

  2. Project 172 • Concept: route 172.x addresses on campus • Target: devices with no Internet access need • DNS and DHCP mods needed • Consideration of NAT: later (would allow “one-way” access for desktops) • Standard “big perimeter” security caveats apply • Pandora’s box?

  3. Wireless Technology News • 802.11a products available • Intel delays 802.11a in Banias chip • DOD worried about 802.11a interference • FCC approves 802.11b phased-arrays • Cisco extends 802.1x for user authentication • Bluetooth interference still a question • 5.8GHz phones appearing!! • 22Mbps “turbo mode” now showing up • BUT: “It’s not done yet…”

  4. Agenda for 1/03 IEEE meeting

  5. Networking Comparison From www.extremetech.com

  6. Coexistence Guidelines (DAWG) • See www.washington.edu/networking • Coordinate frequencies with C&C • Use a unique SSID (avoids trapping users; clarifies support source) • Use *some* security • Recognize tradeoffs vs. centrally-managed service
