"Internet connectivity was delivered utilizing three 5.8 Ghz point-to-point microwave links including a single 20 km (12.42 miles) microwave hop. 802.11b wireless broadband was then delivered through a series of point to multipoint connections throughout the first phase of the community, creating a Wi-Fi (2.4Ghz) "hotspot.""
Yeah that sounds like more. At first I thought they set up ONE hot spot at the end of the link as a test of the link and it worked. Now with the "series of point to multipoint connections" language it sounds like they set up several local boxes and made a bigger hotspot, much bigger than a coffee shop's hot spot for example. It is not a 30km hot spot certainly though.
