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.
IEEE 802.11n is an amendment to IEEE 802.11-2007 as amended by IEEE 802.11k-2008, IEEE 802.11r-2008, IEEE 802.11y-2008, and IEEE 802.11w-2009, and builds on previous 802.11 standards by adding a multiple-input multiple-output (MIMO) system and 40 MHz channels to the PHY (physical layer) and frame aggregation to the MAC layer.
A wireless network interface device with a USB interface and internal antenna A Bluetooth interface card. A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network.
Some of Ralink's 802.11n RT2800 chipsets have been accepted into the Wi-Fi Alliance 802.11n draft 2.0 core technology testbed. They have also been selected in the Wi-Fi Protected Setup (WPS) and Wireless Multimedia Extensions Power Save (WMM-PS) testbeds. Ralink was a participant in the Wi-Fi Alliance and the IEEE 802.11 standards committees. [1]
802.1X clients and servers developed by specific firms may support other EAP types. This certification is an attempt for popular EAP types to interoperate; their failure to do so as of 2013 [update] is one of the major issues preventing rollout of 802.1X on heterogeneous networks.
NDIS 6 supports exposing 802.11 frames to the upper protocol levels, [2] while previous versions only exposed fake Ethernet frames translated from the 802.11 frames. Monitor mode support in NDIS 6 is an optional feature and may or may not be implemented in the client adapter driver.
Diagram explaining conventional Wi-Fi (left) and Wi-Fi Direct (right) Wi-Fi Direct is a Wi-Fi standard for wireless connections [1] that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection.
For wider area communications, wireless local area network (WLAN) is used. WLANs are often known by their commercial product name Wi-Fi . These systems are used to provide wireless access to other systems on the local network such as other computers, shared printers, and other such devices or even the internet.
