SciNet, a volunteer group, will build a massive network to support the SuperComputing Conference in Phoenix next week: Volunteers will build the network in a week then tear it down in two days. It sounds massive--the network will support 150 aggregate gigabits per second and will use more than $16 million in donated gear. Apparently that amount of bandwidth is more than some countries, including Germany, have available in total. As for the Wi-Fi component, the volunteers will deploy 67 access points to distribute the bandwidth around the conference.
