      NIST Finds Wireless Performance Consistent Across 5G Millimeter-Wave BandsNational Institute of Standards and Technology
      
            Wireless transmissions can take many routes to the intended receiver. The colored lines are reconstructions of measured paths of millimeter-wave signals between a transmitter (not visible) and receiver (lower middle) in a NIST industrial control room. Each path is precisely characterized in terms of length and angle to the receiver. These paths are all secondary, meaning reflected or diffracted signals.
