| Most wireless standards come from the IEEE (Institute of Electrics and Electronics Engineers) and, whose 802.11 category covers more than a dozen standards for specific wireless areas, but the Wi-Fi Alliance and WiMax industry group also develop related standards.

| 802.11a | IEEE standard, specifying 54Mbps in the 5Ghz license free band. |
| 802.11b | IEEE standard, specifying 11Mbps in the 2.4Ghz license free band. |
 | IEEE standard, specifying 54Mbps in the 2.4Ghz license free band. |
| 802.11n | New IEEE standard specifying 100Mbps maximum throughput, most likely in the 5GHz band. ( in ratification process, expected mid 2007) |
| Wi-Fi | The Wi-Fi Alliance’s Wi-Fi designation certifies interoperability among 802.11a/b/g devices because each standard has optional components that if not implemented would still technically fulfill the IEEE standards but might not permit interaction with other vendors’ devices. |
| 802.16d,
802.16e | Both are IEEE efforts to standardise wide-area, high-speed wireless zones. 802.16d covers fixed-wireless deployments, whereas the forthcoming 802.16e standard will permit mobile use, such as in trains or cars. |
| WiMax | An effort by the WiMax Forum industry group, this is an evolving certification for 802.16 interoperability standards, similar to the Wi-Fi Alliance’s efforts for 802.11 |
| Security |
| 802.1x | Port based authentication standard. |
| 802.11I | IEEE security standard, this encryption standard replaces the vulnerable static-key WEP standard. It allows for dynamic shared encryption keys. |
| WPA2 | The Wi-Fi Alliance’s WPA2 standard assures interoperability among 802.11i-based devices. (WPA1 was an interim standard issued before the final 802.11i standard) |
| Management, roaming and QOS |
| 802.11e | Defines prioritisation levels and provides basic levels of QoS for data, voice, and video traffic. |
| WME,
WSM | The interim Wireless Media Extensions and Wi-Fi Scheduled Media standards from the Wi-Fi Alliance are based on the draft 802.11e. They’re meant to ensure interoperability and consistent deployment across different vendors’ prestandard products. |
| 802.11f | This IEEE standard defines communication between APs for layer 2 roaming, but it does not support roaming across different WLAN segments |
| 802.11r | This is an IEEE effort to standardise handoff for fast roaming among APs, including authentication keys, to allow fast roaming that will support voice over wireless in addition to data over wireless. |
| 802.11s | Yet another IEEE effort, this standard is designed to wirelessly connect APs for back-haul communication and mesh networking. |
