TDMA in mikrotik world is the protocol NV2. It will work with nearly all routerboards models.
So you can't get TDMA using 802.11 or Nstreme protocols.
All you need is that the base station and clients must use mikrotik ROS.
TDMA of ubiquiti ap's/clients can't talk with mikrotik, is another protocol. (Really they did it before).
I operate a medium size ISP 100% mikrotik and I don't use NV2 at all cause it crashed all the times that i tried it. Randomly, a group of cpe's of a sector get freezed. No ping, no winbox, ... but they appear in registration list all the time. I didn't found the reason, not allways the same clients, different ROS, different routerboards and/or radios, ... Last try was with ROS v5.12.
I use only in a few point to point, and the ping is horrible, moving from 3ms to 25ms. With nstream in the same stations, ping is 0 or 1ms. But Nstream make a lot of interferences to my ap's 802.11, and nv2 don't do it.
