Abstract: Apparatuses, methods, and systems for synchronizing nodes of a wireless network are disclosed. One method includes identifying synchronization paths between synchronization reference nodes of the wireless network and each non-reference node of the wireless network, wherein each synchronization path includes one or more wireless hops between the synchronization reference nodes and the non-reference node, determining a number of timing slots needed for supporting each of the identified synchronization paths, and selecting at least one of the synchronization paths between each non-reference node and at least one of the synchronization reference nodes based on a number of wireless hops of each of the identified synchronization paths and the determined number of timing slots needed to support each of the identified synchronization paths.

Abstract: In one embodiment, a method includes accessing time series data of a wireless communication link between a first node and a second node on a millimeter-wave communications network; determining that an anomaly exists in the time series data; determining an anomaly type for the anomaly by inputting one or more features derived from the time series data into a machine learning module; generating a report comprising an indication that the anomaly exists and a description of the anomaly type, and determining one or more treatments for the determined anomaly.

Abstract: Apparatuses, methods, and systems for monitoring performance of a wireless network and assigning sectors of nodes of the wireless network are disclosed. A method includes monitoring a performance of links between sectors of wireless nodes of the wireless network, assigning or reassigning sectors of the wireless nodes to operate in a first mode based on the monitored performance of the links, wherein all of the sectors operating in the first mode are configured to transmit signals or simultaneously receive signals, and assigning or reassigning sectors of the plurality of wireless nodes to operate in a second mode based on the monitored performance of the links, wherein all of the sectors operating in the second mode are configured to transmit signals when all of the sectors operating in the first mode are receiving signals, or receive signals when all of the sectors operating in the first mode are transmitting signals.
