 more than 10 years ago some company was doing adaptive beam forming WiFi routers&#x2F;switches, and what i remember reading about them is that actual direction of the beam for a given connection wasn&#x27;t necessarily the geographical straight to the other end of the connection, instead it was whatever direction was adaptively found, and that frequently meant very non-straightforward mulitply reflected path. The beauty was that beam power at the &quot;total multi-segmented reflected&#x2F;bounced&quot; length of the path could still be much higher than onmidirectionally transmitted power even at the lesser distance.
