Optical Wireless is a non-coherent, near infrared NIR light source that can be uniformly projected into the far field. It is invisible and can be engineered to be eye safe at the output lens. It uses a small fraction of energy the microwaves use to close the same link. It can be very inexpensive as a tiny chip enables a link over a mile. The chip cost $1 in volume production and the margin can be >100x as patents are substantial. High powers can enable beams from space at much higher bandwidths using much less energy than Starlink or can form a meshed network to connect a community at Gbps inexpensively and quickly. Inexpensive high power high bandwidth LightGrid products will revolutionize the data center by replacing optical fibers with high power beams carrying >400Gbps by using 4 wavelengths and PAM woven in a wireless networked data center. The high power enables parallel connections to multiple locations without switching which fibers must have in their infrastructure. The non mechanical high bandwidth beam directing with NSF development grants have proven a data center with extremely low latency is possible.
