Abstract: Systems and methods for synchronizing subunits a multi-unit power distribution network contemplate selectively opening and closing a switch at the power source to disconnect and reconnect the power source to power conductors to send a synchronization signal to one or more remote subunits. Once the remote subunits are synchronized and able to disconnect from the power conductors, leak detection at the power source may be enabled to detect inadvertent loads on the power conductors (e.g., a human touching the power conductors). Further, the remote subunits may power off and on based on the synchronization signal thereby ensuring that an end device may receive power concurrently from multiple remote subunits so as to meet the power requirements of the end device. Enabling the leak detection improves the safety features of the power distribution network and synchronized power delivery to the end device prevents improper shut downs.

Specifically, the wireless node is configured to dynamically group multiple coverage points (e.g., user equipment, high user density area, etc.) into multiple coverage clusters. Accordingly, the wireless node can form and steer a respective reference beam toward each of the coverage clusters.
