The cities of San Francisco and San Jose are merging their two municipal Wi-Fi networks; at least on the virtual level. The two cities are using a new technology — Hotspot 2.0 — to let smartphones automatically connect and roam between their two networks as well as provide a layer of security on what wouldn’t normally be available in wide-open public hotspots.
Hotspot 2.0 is a bit of a strange technology to highlight because when it’s working you never notice anything happening. The public Wi-Fi network behaves very much like the cellular network and your phone automatically connects to the nearest hotspot access point with a secure WPA2 connection – just as it would connect to your home router.
According to San Francisco Department of Technology CTO Flavio Aggio, security is the main reason why San Francisco decided to upgrade its Ruckus Wireless(s rkus) access points to Hotspot 2.0.
