Abstract
A system that provides a redundant wireless broadband connection between a base station and customer sites is described. The system includes a redundancy system, for example, a standby modem interface card and a plurality of standby outdoor units that are incorporated into the base station. Upon receiving a fault message from a base station component, the redundancy system performs fault correlation to determine whether the fault is indicative of a system level fault. The system also determines whether the fault message affects system operation and performs a switch over based on the determination.
