Beijing November 11, Facebook announced that they successfully using millimeter-wave technology to achieve 20Gbps data transfer rate, the rate also hit a world record. In recent years Facebook has been committed to the construction of communications and Internet infrastructure, especially in remote areas to provide Internet services rather pay attention. And Facebook's Aquila solar drone provides affordable Internet access in a 60,000-foot sky using laser communications and millimeter waves for a 30-mile radius. Wavelength of 1 to 10 mm of electromagnetic waves known as millimeter waves, millimeter waves can provide a very wide bandwidth, and the beam is narrow, with all-weather features, the system easier to miniaturize. However, millimeter waves also have serious attenuation in the atmosphere, device processing accuracy is too high and other issues. As a result, Facebook has achieved a staggering 20Gbps transmission rate over a distance of 13km, which translates into the simultaneous transmission of 1,000 ultra-clear video streams. With Facebook's custom components, the total dc power consumption of transmitters and receivers is only 105 watts. The technology will also continue to be used for the connection between the Aquila drone and the ground station. At present, almost all of the communication capabilities can reach 20 Gbps in the first generation of air-ground two-way communication links for flight testing.
