A communication system is disclosed herein. The communication system includes a master device that includes a master clock and is connected to a host through a communication network, and a plurality of nodes connected to the master device. The master device transmits one or more periodic beams that include a radio frequency. Each of the nodes includes a node clock that is configured and in synchronization with the master clock based on the one or more periodic beams. The communication system establishes a connection for communication between the master device and at least one node when the node clock of the at least one node is in synchronization with the master clock. The communication system further includes at least one repeater 104A operatively connected between the master device and at least one node.
