Big moment for U.S. cities • 1920-2010 • 2011 forward • Fourth era for cities
– Steam engine – Electrical grid/public transportation – Cars – Fiber/data
Four Different Wires • [DSL: “The New Dialup”] • Hybrid fiber-coaxial – cable plant, some portion of pipe
allocated to Internet access, high capacity downstream, cramped upstream
• FTTN – fiber to node, copper between neighborhood node and home, capacity dependent on distance to central office
• FTTH – glass/lasers, potentially unlimited capacity, easily symmetrical (up/down), future-proof, just upgrade electronics
No national path to US upgrade to fiber
1. Comcast, Charter, New Frontier, CenturyLink, and Windstream don’t face competition in their footprints: complete pricing/service-level power
2. Mobile wireless is complementary, not a substitute (data caps, low capacity)
– 85% of people with smartphone also have wire at home; 95% of wireless is a wire
– WiFi becoming much larger portion of wireless use than mobile
Why Fiber • Google’s self-driving car will produce a GB of data
every minute • SMEs, science, agriculture… • Cloud storage, data processing • Sensor data will be overwhelming • Need no delays, unending increase in capacity…
Privacy Protect anonymity Ensure secure storage Forensics/accountability Increase transparency
