"high-speed, high-bandwidth wireless communication at terahertz frequency across long distances... able to form 2 km link... Instead of trying to fix information at receiver, pre-distort signal such that when goes through source, becomes error-free... frequencies and bandwidths that eclipsed 5G networks by more than two orders of magnitude... need to have line of sight so no obstacles to signal's path; great for connecting towers across farms, lands... eventually may beam from space"
