[13] [n 1] A null SSID (the SSID element's length field is set to zero [11]) is called a wildcard SSID in IEEE 802.11 standards documents, [14] and as a no broadcast SSID or hidden SSID in the context of beacon announcements, [13] [15] and can be used, for example, in enterprise and mesh networks to steer a client to a particular (e.g. less ...
When users chooses to hide the network name from the router's setup page, it will only set the SSID in the beacon frame to null, but there are four other ways that the SSID is transmitted. In fact, hiding broadcast of the SSID on the router may cause the Network interface controller (NIC) to constantly disclose the SSID, even when out of range. [2]
A broadcast address is a network address used to transmit to all devices connected to a multiple-access communications network. A message sent to a broadcast address may be received by all network-attached hosts. In contrast, a multicast address is used to address a specific group of devices, and a unicast address is used to address a single ...
The SSID is configured within the devices that are part of the network. A basic service set (BSS) is a group of stations that share the same wireless channel, SSID, and other settings that have wirelessly connected, usually to the same access point. [40]: 3.6 Each BSS is identified by a MAC address called the BSSID.
April 2019) (Learn how and when to remove this message) In a hierarchical telecommunications network , the backhaul [ 1 ] portion of the network comprises the intermediate links between the core network, or backbone network , and the small subnetworks at the edge of the network (like for example private networks , LANs , etc. [ citation needed ] ).
A wireless distribution system (WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them.
A broadcast storm or broadcast radiation is the accumulation of broadcast and multicast traffic on a computer network. Extreme amounts of broadcast traffic constitute a broadcast storm . It can consume sufficient network resources so as to render the network unable to transport normal traffic. [ 1 ]
Broadcast frames from all other sources are directed only to the provider nodes. Traffic from other sources not destined to the provider nodes ( peer-to-peer traffic) is blocked. The result is a network based on a nominally shared transmission system; like Ethernet, but in which client nodes cannot communicate with each other, only with the ...
