Lisbon’s Parque das Nações becomes massive Wi-Fi zone with 100 mesh access points covering 100 hecatres/250 acres: The park was the site of the 1998 World’s Fair, and access will be free for the first six months. It then moves into a vendor-neutral host position in which any wireless ISP can resell access. The network will divide itself into VLANs with unique SSIDs for each WISP — a very clever idea, indeed, because VLANs with unique SSIDs can run as an overlay on a single infrastructure. The project is backed by the government and the agency running the park.
