Long-distance Wi-Fi Transmission

I am engaged in Linux driver development. Now we need to implement the function of transmitting video data (omnidirectional antennas) over a long distance (about 1km) over wifi between two ends. The currently used platform is Atheros AR9342. I found some information on the Internet about disabling the 802.11 CSMA function to use TDMA Transmission for remote transmission. I modified the mac layer according to the method in it. One of the methods is to disable sending and wait for a response. Adding it will cause data transmission problems (video data transmission, you can see a clear screen ). At present, there is no good way to solve this problem, so I will post an article here, hoping that friends with similar experience can discuss it together. Thank you.
