The availability of WiFi bandwidth downtown varies widely–several private companies and even public agencies charge for access, but hot spots in some plazas and parks are free. Some believe WiFi should be considered a public good–like streetlights–and thus always be available gratis. Today Jimm Dispensa of Friends of Downtown, Stelios Valavanis, of the IT company onShore, and Spiro Papadopoulos of ePrairie.com will have a conversation about how other cities have offered WiFi access for free, give some estimates of the costs involved, and discuss other ways Chicago could integrate the technology into city services. WiFi in Downtown Chicago runs from 12:15 to 1:15 PM in the Claudia Cassidy Theater at the Chicago Cultural Center, 78 E. Washington in Chicago. It’s free; call 773-744-6630.
