Facebook demonstrates record-breaking data rate using millimeter-wave technology

This post details the demonstration of a record data rate of nearly 20 Gbps over 13 km using millimeter-wave (MMW) technology. It highlights the use of custom-built, high-linearity RF components and custom-built MMW power amplifiers with high-efficiency power combining techniques. The post also describes the development of post-amplification spectrum multiplexing to improve power amplifier efficiency and the use of conical scanning for high-precision antenna pointing and calibration using sun tracking. The technology is intended for terrestrial backhaul, backup for optical solutions, and as a link between ground stations and the Aquila UAV.
