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!
