Look up the DIY parabolic reflectors people used to use on their WiFi antennas, they did actually work! I used one and recorded a marked improvement in WiFi strength at the furthest point in my home that was previously a low connection quality spot.
Radio waves come out of an antenna and just go in every direction, so a router against your outer wall is wasting a lot of its energy just directed into the neighbour’s house. If you can reflect some of that back in, you get improved signal reception. It’s very cool :-)
But if waves transmit information, and the same information comes at all sides, won’t the signals that bounce off the reflector arrive after the waves with a direct line and thus transmit redundant information?
Waves can bounce off of everything, wifi/Bluetooth/cellular automatically compensate for this effect. There is a lot of signal processing involved with wireless data transmission to filter noise and correct errors. This is part of the reason why it’s taken decades to reach this level of wifi speeds and why Bluetooth has a real hard time matching wired audio.
