For more information about standard-compliant (IEEE 802.11) Wi-Fi protocols, see IEEE 802.11 on Wikipedia.

Standard and non-standard (proprietary) Wi-Fi protocols and extensions:

NCR / AT&T / Lucent proprietary, 900MHz / 2.4GHz ISM
2.4GHz 1, 2Mbps only, DSSS / FHSS, aka IEEE 802.11-1997 or IEEE 802.11-1999
  • Whitecap - Cirrus Logic / ShareWave proprietary extension to 802.11, QOS oriented
  • 802.11a (1999) - 5GHz, 54Mbps, OFDM
  • 802.11b (1999) - 2.4GHz, 1, 2, 5.5, 11Mbps, DSSS, CCK
  • 802.11b+ - Texas Instruments proprietary extension to 802.11b. 22Mbps.
Also known as Packet Binary Convolutional Code (PBCC) technology, PBCC-22, b+ [1]
different MAC (dynamic TDMA similar to modern LTE standard)
Also marketed as: 108G Technology, 108Mbps 802.11g, and Xtreme G, Turbo G. A similar concept became part of 802.11n (HT 40MHz).
Also known as: 125HSM, Afterburner, 125Mbps 802.11g, SpeedBooster, Turbo G, G Plus, MAXg.
A similar concept became part of 802.11n (WME).
  • G++ Technology - Texas Instruments proprietary 802.11g extension, 125MBps, packet bursting etc.
Also marketed as: g+ SuperSpeed [3]
Frame bursting, etc. 140Mbps, also marketed as: DirectLink
  • True MIMO - Airgo Networks proprietary MIMO extension to 802.11g. A similar concept became part of 802.11n.
Also marketed as: SRX (Speed and Range eXpansion). Not compatible with pre-n / draft-n / final 802.11n standard.
  • 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rarely used in practice; withdrawn in 2011 WLAN Authentication and Privacy Infrastructure on Wikipedia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)
  • pre-n - (2005-6) an even earlier version of draft-n...
  • draft-n - (2007) Compatible with the final IEEE 802.11n standard up to MIMO 2x2
  • 802.11n - (2009) 72Mbps (20MHz), 150Mbps (HT 40MHz), 300Mbps (HT 40MHz MIMO), 450Mbps (MIMO 3x3)
  • 802.11ac - (2013) 450/600Mbps (2.4GHz) & 1300/1750Mbps (5GHz), MIMO up to 4x4, 80MHz channel
  • 802.11ac Wave 2 - (2014) MU-MIMO, MIMO up to 8x8, 160MHz channel
  • 802.11ad aka WiGig - (2012) 6.75 Gbps (60GHz) Wireless Gigabit Alliance on Wikipedia

Unless noted, proprietary protocols are not compatible with each other (for example TI G++ 125Mbps is not compatible with Broadcom 125Mbps HSM).
