"fastest wireless data transmission ever demonstrated over this long a distance in an urban setting... using advanced interference-free optical antennas from Aircision... free-space optical communication... technique commonly used in fiber optics combines multiple wavelengths in single transmission... IR highly focused, enabling almost unlimited number of communication links existing side-by-side without interference in all weather conditions... 5G/6G antennas backhauling existing network where fiber impractical/ too costly"
