802.11 and 802.11x refers to a family of specifications developed by the IEEE for wireless LAN (WLAN) technology. 802.11 specifies an over-the-air interface between a wireless client and a base station or between two wireless clients. The IEEE accepted the specification in 1997.
There are several specifications in the 802.11 family:
* 802.11 [...]
The name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. The Wi-Fi Alliance, the organization that owns the Wi-Fi (registered trademark) term specifically defines Wi-Fi as any “wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) [...]
A wireless LAN (WLAN) is a wireless local area network that links two or more computers or devices using spread-spectrum or OFDM modulation technology based to enable communication between devices in a limited area. This gives users the mobility to move around within a broad coverage area and still be connected to the network.
For the [...]
IEEE 802.11 is a set of standards carrying out wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands. They are implemented by the IEEE LAN/MAN Standards Committee (IEEE 802).
The 802.11 family includes over-the-air modulation techniques that use the same basic protocol. The most popular are those defined by [...]
The geographic boundary covered by a Wi-Fi (802.11) wireless access point. Typically set up for Internet access, anyone entering the hotspot with a Wi-Fi-based laptop, PDA or smartphone can connect to the Internet, providing the access point is configured to advertise its presence (beaconing) and authorization is not necessary. If authorization is required, the user [...]
The wireless version of Ethernet. Wi-Fi is the wireless equivalent of the wired internal local area networks (LANs) used in companies worldwide. A Wi-Fi logo from the Wi-Fi Alliance certifies that network devices comply with the IEEE 802.11 wireless Ethernet standards.
In the early 2000s, 802.11b became widely used, followed by 802.11a and 802.11g. The latest [...]
Wi-Fi is a trademark of the Wi-Fi Alliance for certified products based on the IEEE 802.11 standards. This certification warrants interoperability between different wireless devices.
In some countries (and in this article) the term Wi-Fi[1][2] is often used by the public as a synonym for IEEE 802.11-wireless LAN (WLAN).
Not every IEEE 802.11 compliant device is certified [...]
