Most WISPs are heavily using Ubquiti Geard (as well a Tranzeo, and Motorola). Many of the WISPs include the cost of a wireless router in the install price because they generally do double natting internally and they want something they've tested to work with their systems. It's better for them to spend a little more (even if it is billed to the customer) up front a make sure they know it will work/the customer should be happy. I can see this being heavily used for home connections with WISPs espcially since they can just power both the Outdoor AP and the router off the Passive POE. I'm not sure what they were thinking for the indoor AP. I think it would have done better if they put just a cheap 2.4/5ghz N AP into the router for the home users.
