Abstract
Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network, in particular an aggregation node (AGN). The AGN includes a plurality of spatially switched antennas and a transceiver configured to operate on the plurality of spatially switched antennas in a time divisional multiplexing (TDM) fashion to establish active connections with other network nodes in a hierarchical manner. The AGN is further configured to perform a bi-directional relay function for backhaul traffic with the other network nodes using at least one virtual circuit having an allocated bandwidth for delay sensitive traffic. The AGN may serve to aggregate and relay/amplify circuit traffic between network nodes in the up stream and down stream directions. If the AGN is interposed within a circuit between two other nodes, the AGN can switch the circuit traffic between the end-nodes of the circuit.
