Openwifi code has dual licenses. AGPLv3 is the opensource license. For non-opensource license, please contact Filip.Louagie@UGent.be. Openwifi project also leverages some 3rd party modules. It is user’s duty to check and follow licenses of those modules according to the purpose/usage. You can find an example explanation from Analog Devices for this compound license conditions.

Features:
802.11a/g
802.11n MCS 0~7 (Only PHY rx for now. Full system support of 802.11n will come soon)
20MHz bandwidth; 70 MHz to 6 GHz frequency range
Mode tested: Ad-hoc; Station; AP, Monitor
DCF (CSMA/CA) low MAC layer in FPGA (10us SIFS is achieved)
Configurable channel access priority parameters:
duration of RTS/CTS, CTS-to-self
SIFS/DIFS/xIFS/slot-time/CW/etc
Time slicing based on MAC address
Easy to change bandwidth and frequency:
2MHz for 802.11ah in sub-GHz
10MHz for 802.11p/vehicle in 5.9GHz
On roadmap: 802.11ax
Performance (AP: openwifi at channel 44, client: TL-WDN4200 N900 USB Dongle):
AP —> client: 30.6Mbps(TCP), 38.8Mbps(UDP)
client —> AP: 17.0Mbps(TCP), 21.5Mbps(UDP)”
