Hi Ben,
TDMA doesn't require synchronization between the radios. This would be
Ubiquiti's AirSync technology and that's for another usage. When you
have two or mode radios colocated in a tower receiving and transmitting
at the same time so it avoids them do it at the same time and
synchronizes Receive and Transmit.
TDMA is more to be used in PtMP environments where you have multiple
customers talking to the AP and they don't see each other, so the AP is
able to organize more correctlly the time each one sends data. That's
probably why it was only implements on proprietary systems usede by
WISPs with different names.
Regards,
Fernando

In an old thread on the Battlemesh listserv about strategies for
dealing with a mix of strong / weak clients for PtMP, someone offered
this pointer for JaldMAC, an open 802.11 polling implementation in ath9k:

https://github.com/shaddi/jaldimac/commits/master
Unfortunately, that repo has sat idle for over 2 years, and I believe
it it was more a proof of concept rather than a usable implementation.
Also, i believe TDMA requires very tight synchronization between all
radios, hence the inclusion of GPS modules on proprietary implementations.

Hi all,
Is anyone aware of any implementation of TDMA mode support in
OpenWRT (similar to Ubiquiti's AirMAX, Deliberant's iPoll or
MikroTik's NV2, etc)
Would that have to be implemented having in mind the radio driver
or could it possible also be implemented in any router ?
This is certanlly something significant for more throughput
demanding and crowded environments.
Best regards,
Fernando
