When communicate with commercial device, tcp can achieve ~30M, UDP can achieve ~38M in 20MHz 11a/g non MIMO mode. We are still working hard to optimize the whole design, because we know it is not mature enough and there is still lots of work to be done. For example, the original PHY rx openofdm design is simplified a lot for a quite small fpga which means performance (like sensitive) is sacrificed. Now our FPGA is more advanced than the openofdm FPGA in USRP N210, so there is a chance to improve a lot on both performance and features (like MIMO and new standard). Recently nlnet.nl gives us a short term fund to complete the 802.11n feature: https://nlnet.nl/project/OpenWifi-80211n/index.html
There are lots of information (including throughout) in the readme and “project document” on GitHub (https://github.com/open-SDR/openwifi). Worth to read word by word.
