Exploiting Non-Line-Of-Sight Links for Terahertz Signals to Enable Ultrafast Wireless Data Transmission

If a base station in a local area network tries to use a directional beam to transmit a signal to a user trying to connect to the network -- instead of using a wide area network broadcast, as base stations commonly do -- how does it know which direction to send the beam-
