Facebook says it has demonstrated a record point-to-point data rate of 36 Gbps over 13 km with millimeter wave technology, and 80 Gbps between those same points using its optical cross-link technology.
Facebook also demonstrated 16 Gbps transmission, simultaneously in each direction, from a location on the ground to a circling Cessna aircraft over 7 km away. Facebook believes that is important as a number of different connectivity solutions can be supported using the same fundamental platform.
It can serve as a terrestrial backhaul network to support access solutions like OpenCellular, or as a reliable backup to free space optical solutions such as the laser communications and optical detector in case of fog and clouds.
Ultimately, the point-to-point radio link also is expected to serve as the connection between a ground station and Aquila, the Facebook unmanned aerial vehicle.
In dense urban regions, Facebook assumes its Terragraph multi-node fixed wireless system can bring high-speed internet connectivity to dense urban areas.
Our idea is to extend fiber using wireless instead of more fiber, to build faster networks at a lower cost, said Facebook staffer Yael Maguire.
