If you operate a modern AP (802.11ac/ax, e.g. Aruba 518) with external antennas and the antennas are 50m away from each other, what are the consequences?
Let us assume that the connectors and the cable length do not cause too much attenuation.
Background:
A customer wants to provide the outside of a house with WLAN. He thinks that an AP with 4 external antennas is a good solution. One antenna at each corner of the house.
I contradicted him out of intuition.
But I can't really justify it technically, except that it wouldn't be a good idea to lay antenna cables next to power cables.
My main argument to the customer was that the cost would be almost as high as just taking 4 cheap APs. Which would allow a higher client density.
