Abstract

A communications network is disclosed that includes one or more microwave backhaul nodes for routing communications between one or more near end mobile communications devices and one or more far end mobile communications devices. The communications network includes a central monitoring and control infrastructure, a remote monitoring and control infrastructure and/or a local monitoring and control infrastructure. The central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure can directly manage the one or more microwave backhaul nodes. Alternatively, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure can indirectly manage the one or more microwave backhaul nodes through the central monitoring and control infrastructure.
