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

What this post added

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 development of custom-built, high-linearity RF components, high-efficiency power amplifiers using post-amplification spectrum multiplexing, and advanced antenna tracking techniques (sun tracking for bore-sight calibration and conical scanning for precision pointing). The post also discusses the technical challenges of MMW spectrum, including RF component technology, antenna design and tracking, and atmospheric attenuation, and outlines next steps for flight testing air-to-ground bidirectional links.
