- WAPI - (2003-2011) Chinese Wi-Fi standard; officially, the implementation was mandatory for Wi-Fi products in China;
- rarely used in practice; withdrawn in 2011 WLAN Authentication and Privacy Infrastructure on Wikipedia
- WirelessHD aka UltraGig - (2008) Proprietary 60GHz standard by SiBeam (became Silicon Image, later Lattice)
