I'd say this won't work, because of roaming issues (ie. handover issues) and interference issues

You might be better using Ubiquity's Zero-Handoff APs
or Meru's (now Fortinet) Seamless Roaming approach.

With Microcell architecure and without extended Roaming support you're lost here.

I am not familiar with the Upiquity products. I just know that there is support for zero-handoff roaming.

Mikrotik Hotspot works as long as you establish a Layer-2 Connection between End-User and Hotspot Gateway.
This might include ordinary bridging, tunneling with EoIP/L2TP or MPLS/VPLS

Scan-list in stations, limit to APs frequency.
And use mode=station-roaming for zero handoff

Use device like OmniTik for AP; because when approach the AP and when getting away AP, don't lose connection to AP

can omnitik roaming fast wireless network from ap to ap (dynamic WDS )? for example I installing OMNITIK on train and many OMNITIK on the tunnel, is roaming fast between the two omnitik's ? the train speed is 32 km/h up to 70 km/h

OmniTik better than SXT for AP in this solution, because SXT cover one side but OmniTik cover two side of AP.
In configuration no deference between SXT and OmniTik.

Sorry for delay as my time to spend here on forum is quite limited during last weeks... Do you have any progression in this interesting area?
