Moovera releases a Wi-Fi metro-scale node with 3g, WiMax backhaul: While this might seem like a specialized item, the folks a Moovera assure me that there are many markets in which conventional mesh (sharing frequencies to move packets around a set of nodes) and point-to-multipoint backhaul just won't work. 3G and WiMax are increasingly available, and thus reasonable options for a freestanding node or set of nodes. The Moovbox F100 has dual-band Wi-Fi, and can support all major flavors of 3G as well as mobile WiMax. The node pricing starts $1,200.
