ORCA partner IMEC has launched an open source project: Openwifi!
It is a Linux mac80211 compatible full-stack Wi-Fi design based on SDR (Software Defined Radio). Connection with commercial Wi-Fi device as AP or station in IEEE 802.11a/g/n (mcs0-7) mode is working out of the box. In addition, openwifi also allows configuration of channel access priority and time sharing of the interface. The support of IEEE802.11ax is on our road map.
