Abstract After twenty years, the "S-curve" of building out the wired internet with hundreds of millions of PCs as its end points is flattening out, with corresponding lowering of the growth rates of the major suppliers of that global infrastructure. At the same time, several new "S-curves" are reaching their steep slope as ubiquitous computing begins to sweep the planet. Leading this will be a vast expansion in heterogeneous end-points to a new wireless internet, moving IP throughout the physical world. Billions of internet connected cell phones, embedded processors, hand held devices, sensors, and actuators will lead to radical new applications in biomedicine, transportation, environmental monitoring, and interpersonal communication and collaboration. The combination of wireless LANs, the third generation of cellular phones, satellites, and the increasing use of the FCC unlicensed wireless band will cover the world with connectivity. The resulting vast increase in data streams, augmented by the advent of mass market broadband to homes and businesses, will drive the backbone of the internet to a pure optical lambda-switched network of tremendous capacity. Finally, peer-to-peer computing and storage will increasingly provide a vast untapped capability to power this emergent planetary computer.

Urban Areas Have WLAN Node Movements to Create “Free” Internet Connectivity “If you have a broadband or DSL connection in your home or office, buy an access point, hook it up, and you are a node operator.” “The project grew out of a skepticism towards the claims of the telecom industry regarding the usefulness and success of the future "third generation mobile telephone systems" as the only means to implement "the wireless Internet". “ “We envision a cloud of free Internet connectivity that will cover most inhabited areas. The coverage might be spotty, vary over time, and be hard to control or predict, just like a fog or smog. “ 369 members in Sweden as of June 1,
