George: Well...it is a pilot project. :) But one of the 2.4 GHz radios uses the MEA (Mesh Enabeled Architecture) and the other 2. 4Ghz radio uses the normal 802.11. The same for the 4.9 GHz. See weblink.
http://mrtmag.com/mag/radio_motomesh_not_public/index.html The real issue is many utilities and munis are seeking ways of automating their utilities into a "smart grid" and wireless is part of the strategy. Let's say you are owner of a muni and you've just installed a "muni wifi". They city manager immediately thinks of ways to "leverage" the "WiFI" system (802.11 whatever) in 2.4 GHz or other. Granted there exist the usual interference challenges with teh 2.4 GHz and all of the other access points and such in homes etc. Some are incorporating near field "zigbee" into utility meters and then meshing those zigbee enabled meters onto a mesh system/collector then backhauling that to fiber POP.
