Meet the Start-Up That Wants to Turn Your City Into One Big WiFi Hotspot

You've heard of the "internet of things." Get ready for the "internet of moving things."

That's how a start-up called Veniam describes its mission to transform all the cars, trucks, and buses on city streets into a mobile WiFi network connecting anything and anyone around it. Veniam has already brought a version of this free public network to Porto, Portugal, where it's using some 600 vehicles to test the technology in a "living lab."
