Backhaul: Why [Not] Wi-Fi?
The MetroFi experience (2004 – 2008)
→ Free Wi-Fi & sell ad space model
→ Metering? - not our business model
→ SVP Purchase of SkyPilot WAN
→ The Trilliant test (and marriage)
Santa Clara Free Wi-Fi
→ It’s ours -- for better, for worse
→ Two years of operation
→ It Works (mostly)
→ Customer Love - Loathe it

Security
• Security issues are a threat to the entire IT space
• Stuxnet shows us that all systems can be vulnerable
• Smart Grid is both “wired” and wireless
• Biggest security issue remains at the staff/human
interface level.
• Active system monitoring and critical system
redundancy
• Design security and privacy into the system from the
start – and TEST IT!
