24GHz will require line of sight. I can't see how this is going to work for anything more than cell backhaul or fixed wireless access in very rural areas (without trees)?
At relatively short distances (hundreds of meters), enough radio waves bounce around in the environment to still make it to the receiever. https://spectrum.ieee.org/telecom/wireless/smart-antennas-co.... You need beam forming antennas to take advantage of this fact.
