I'm not an expert in 5G, but I was under the impression that the antennas and protocol support far more advanced beamforming than is available to other wireless tech. I remember reading somewhere that it has a lot on common with phased array radar systems. Here is a Wikipedia link: https://en.m.wikipedia.org/wiki/Smart_antenna https://en.m.wikipedia.org/wiki/Smart_antenna What I can't square away is I also remember learning about beamforming in my Wireless engineering course, and I thought WiFi had some similar too. But for some reason my brain is telling me 5G can beam really narrow "spotlights" of signal to the client devices. Sorry for the vagueries but it's all I can recall.
