...or the service will be used like Sprint is using Clear AT&T won't have as much spectrum in WCS as Clearwire has in EBS+BRS. The spectrum is also paired, which isn't as good of a bit for download-intensive cellular data traffic. However it's the best AT&T can get for spectrum that focuses on capacity more than coverage, and WCS *will* reach a little farther than BRS/EBS.
While AT&T could in theory launch something like VZW HomeFusion, using a combination of 700, AWS and WCS spectrum for LTE, my bet is that they will focus on the same thing Sprint will focus on when utilizing Clearwire spectrum: offloading some macrocell traffic to smaller, higher-capacity cells in areas where demand is very high. Look for microcells supporting WCS a few years from now where AT&T is trying to use WiFi offloading now. You won't be able to pull a signal more than a mile away from a WCS site outdoors (or half a mile indoors), however within that radius the network will be nice and fast.
