Re: [OpenWrt-Devel] IEEE 802.11 TDMA mode support in OpenWRT

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

2014-07-03 Thread Fernando Frediani
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

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: http://matthias.vallentin.net/papers/nsdr10.pdf
