Abstract: A communication network includes nodes configured into a wireless ring network operating at one or more millimeter-wave frequencies. At least one of the nodes is configured to send and receive millimeter-wave wireless signals through an obstruction. In accordance with an exemplary embodiment of the network, one or more of the nodes may include small, phased-array antennas and transceivers, configured with radio electronics to mitigate the path loss through certain obstructions, such as walls, floors, ceilings, and other barriers within buildings, as well as attenuation from free-space path-loss, including moisture in air (humidity). The network may include multiple pairs of nodes to form one or more wireless communication paths through various obstructions. This may allow a high-speed, wireless, multi-ring network to be established, for example, within a structure, such as a building, without requiring additional cabling or wiring.
