Several radios and a so SSID

There is possibility to use several radios with a single SSID, ie, the client will appear for only an SSID.

yes you can do that ,

first set your all the radios in ap bridge mode use single ssid and make them wds enabled .

But I can put the same channel for all Router Boards?

Hi Nilesh,

If the wireless cards (you want to have a single SSID) are on the same mikrotik board, do you still do it with WDS?
And if so, with each other’s mac-addresses as well?

In WDS you have to put each AP on same channnel, same ssid and when you are configuring wds dynamic you don’t have to add any mac address manually. enable stp protocol on your bridge interface.
