The Mach Node Slum is my take on a wireless cloud build-out. (DonPark)
The Mach Node Slum is a network of HotZones.
A HotZone is an area of wireless coverage larger than a HotSpot.
The core of a HotZone is a unix server with routing capabilites and at least one network interface. A HotZone can be expanded at the layer 2 level with repeater access points.
A HotZone is powered by a soekris box has an extended layer 2 region with single or back-to-back DWL-900AP+.
A HotZone is linked to another HotZone by participating in the same VPN. All HotZones communicate via IPv6 only, using IPv4 tunnels where necessary.
