Abstract

Devices and methods are provided for providing wireless coverage redundancy in case, for example, the backhaul of an access point (AP) base station is not available. In one embodiment, the method involves monitoring the backhaul, and in response to the backhaul being available, facilitating communication between an access terminal (AT) and the macro network via the backhaul. In addition, or in the alternative (e.g., when the backhaul is not available), a communication signal between the AT and a macro base station (or another AP base station) may be boosted.
