Beamforming can&#x27;t overstep the physical limitations of a carrier wave, it just adapts the radiation pattern of the antenna array to improve range and reduce interference. This is useful to extend the range of high-band signals, because they operate in object-dense space with a high density of clients. It is also useful at the lower frequencies, because it allows an improvement in spectrum…</p><p><a href="https://hackerpaper.kaipfister.de/p/1902.07678/">Paper and discussion history</a>.
