In IEEE 802.11 wireless local area networking standards (including Wi‑Fi), a service set is a group of wireless network devices which share a service set identifier ( SSID )—typically the natural language label that users see as a network name. (For example, all of the devices that together form and use a Wi‑Fi network called "Foo" are a service set.) A service set forms a logical ...
The term has also been used to refer to wireless security by hiding the network name ( service set identifier) from being broadcast publicly. Many routers come with this option as a standard feature in the setup menu accessed via a web browser.
In an infrastructure mode network the WNIC needs a wireless access point: all data is transferred using the access point as the central hub. All wireless nodes in an infrastructure mode network connect to an access point. All nodes connecting to the access point must have the same service set identifier (SSID) as the access point.
IEEE 802.11r-2008. IEEE 802.11r-2008 or fast BSS transition ( FT ), is an amendment to the IEEE 802.11 standard to permit continuous connectivity aboard wireless devices in motion, with fast and secure client transitions from one Basic Service Set (abbreviated BSS, and also known as a base station or more colloquially, an access point) to ...
Traffic Identifier. In a WLAN, packets can be a stream of video, voice, or data, which each have different priorities to be served by an access point. The Traffic Identifier (TID) is an identifier used to classify a packet in Wireless LANs. When a base station receives an 802.11 frame with the TID set for audio, for example, the priority given ...
A network manager may consider the requirements of power consumption and communication throughput of client devices in a particular wireless network when determining which DTIM period to configure for which service set.
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 standards allow for channels to ...
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
