Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards. Location of the network device drivers in a simplified structure of the Linux kernel.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:2.4 GHz Wi-Fi channels (802.11b,g WLAN).svg|lang=en]] for the
IEEE 802.11s is a wireless local area network (WLAN) standard and an IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create a wireless LAN mesh network, which may be used for relatively fixed (not mobile) topologies and wireless ad hoc networks. The IEEE 802.11s task group drew upon volunteers from ...
Ralink Technology, Corp. is a Wi-Fi chipset manufacturer mainly known for their IEEE 802.11 (Wireless LAN) chipsets. Ralink was founded in 2001 in Cupertino, California, then moved its headquarters to Hsinchu, Taiwan. On 5 May 2011, Ralink was acquired by MediaTek.
The 802.11w amendment is implemented in Linux and BSDs as part of the 80211mac driver code base, which is used by several wireless driver interfaces; i.e., ath9k. The feature is easily enabled in most kernels and Linux OS's using these combinations. OpenWrt in particular provides an easy toggle as part of the base distribution.
It has seen widespread worldwide implementation, particularly within the corporate workspace. While the original amendment is no longer valid, the term "802.11a" is still used by wireless access point (cards and routers) manufacturers to describe interoperability of their systems at 5.8 GHz, 54 Mbit/s (54 x 10 6 bits per second).
IEEE 802.11u-2011 is an amendment to the IEEE 802.11-2007 standard to add features that improve interworking with external networks.. 802.11 is a family of IEEE technical standards for mobile communication devices such as laptop computers or multi-mode phones to join a wireless local area network (WLAN) widely used in the home, public hotspots and commercial establishments.
