:What Comcast might do though is setup these WiMAX repeaters on top of apartment/condo buildings so that they don't have to wire up every unit. They can't do that with WiFi as reliably today for large buildings. They could even cover entire neighborhoods with one repeater.
And then you could have a WiMAX/WiFi router to cover all your devices.
I dont think Comcast will do any kind of equipment/antenna placements on building. Since they invested in Sprint/Clearwire, they will only (as of now at least) be doing resale. By providing femtocells to their end users, they can give them a seamless experience both in their homes (via the Comcast femtocell) and outside (via the Sprint/Clearwire network).
