1. A communication network, comprising:a plurality of nodes capable of wirelessly communicating with each other by way of millimeter-wave signals, wherein the nodes are configured to communicate with each other by transmitting or receiving one or more millimeter-wave beams through a physical obstruction that attenuates the millimeter-wave beams passing therethrough, wherein each of the nodes includes:
a first phased array antenna configured to transmit a first millimeter-wave beam through the physical obstruction;
a second phased array antenna configured to receive a second millimeter-wave beam through the physical obstruction; and
wherein the first phased array antenna and the second phased array antenna are each configured, respectively, to mitigate path loss experienced by the first and second millimeter-wave beams passing through the physical obstruction.
