Kring And depending on your router, the backhaul can be faster than wired.
I see speeds of around 400 Mbits/sec-ish between units if signals have good SNR. The "eero 6 pro" is a bit faster (4x4 radio for backhaul), but from my usage, does not appear to make that huge a difference.
Many people use wired backhaul to connect their eeros to get better speeds, and for greater stability. This will avoid the problem of eeros interfering with one another when they are close to one another -- you can't avoid that sometimes, when you have devices and computers that want to be directly wired.
For some reason, my ASIAIR based all-sky camera transfers data at no better than 50 Mbits/sec through its WiFi station mode. So, even wireless backhauls between mesh nodes will feel so much faster than connecting to ASIAIR through WiFi.
I have just started writing a macOS (Cocoa) framework for INDIGO, and at some point will have better data on how fast I can fetch camera data through INDIGO Sky (Raspberry Pi 4); hoping to get Bin1x multi-star autoguiding at 0.5 second exposure to reach 2 FPS -- the ASIAIR needs Binx2 to get a guiding frame rate of better than 1FPS with any of ZWO's cameras.
One thing I can say about INDIGO Sky is that it is absolutely solid, although I am just starting to write and test the code by going through a ZWO EAF (easiest device that can visibly test the API of my framework); no massive BLOB data transfer yet. The Raspberry Pi box has been on continuously for a couple of weeks now and don't even hiccup. I updated its firmware once a couple of weeks ago, where it went directly to the Internet to update itself, and then rebooted itself, and reappeared on the INDIGO bus as if nothing has happened :-). I am pretty certain that the next all-sky camera (using EOS lenses instead of CCTV lenses) that I am constructing will be using INDIGO Sky instead of ASIAIR.
Speaking of which, my GUI to test the framework uses a hold-mouse-button-down-to-keep-slewing the EAF, and it is so much easier to use than to keep pressing the one-move-per-tap interface that ZWO chose for ASIAIR's EAF control.
