I think you could approximate the phased array and frequency multiplexing with a bunch of dish antennas connected to separate radios, but the dishes would need to be connected to motors to follow moving targets. It would also require a lot more physical space.
The neat thing about phased arrays is that they are solid state, aka no moving parts, so they have a much faster response.
Here is a really good presentation on how they work and how to build one.

- mmooss 2y agoSorry, I wasn't clear with what I was saying - but now I understand what you meant anyway. Thanks.
- aeonik 2y agoGlad it helped, I just now see you are talking beamforming. Beamforming is achieved using phased arrays. I'm not sure if all beam forming uses phased arrays, but one of the terms is just talking about the wave itself (beamforming), while phased array is talking about how the beamforming is achieved. That being said, I don't want to presuppose that you can't beamform form without phased arrays.
- simonm21 2y agoTo complete what is has been said by the community, I suggest to look at the CWNA certification to begin your Wi-Fi journey. It explains perfectly all the base knowledge that all guys working on Wi-Fi should have. It's independent and not related to any vendors, that's why this certification is the best to begin with.
