Today I am going to talk about the structure of wireless networks such as SSID (Service Set Identifier), BSS (Basic Service Set), and ESS (Extended Service Set.) <\/p>\n\n\n\n
SSID-<\/strong> An SSID (Service Set Identifier) is the name of a wireless network that a user sees when they scan for available WiFi connections\/networks on their devices. An SSID is used to identify and distinguish one wireless network from another and typically is broadcast by a router or WAP (Wireless Access Point) so client devices can discover the wireless networks available and connect to them.\u00a0<\/p>\n\n\n\n BSS- <\/strong>A BSS (Basic Service Set) is a group of wireless network devices that communicate through a single AP. The characteristic of a BSS is that it is solely for one AP, and operates in a star topology. A BSS includes the AP and all associated client devices such as laptops, smartphones, and tablets, that are connected to it. Just like a star topology, communication from one end device to another end device must first go through the AP. End devices communicate through the AP rather than directly.\u00a0<\/p>\n\n\n\n BSSID-<\/strong> A BSSID (Basic Service Set Identifier) is a unique identifier assigned to a specific BSS in a wireless network. It is typically the MAC address of an APs radio interface and is used to distinguish one BSS from another.<\/p>\n\n\n\n BSA- <\/strong>A BSA (Basic Service Area) is the physical coverage region area where multiple wireless devices can communicate with a specific AP. Think of a 3500 sq foot home with one SOHO router, the whole house is essentially the BSA, since the wireless network is reachable to all areas of the home. The BSA represents the geographic area where the RF signal is strong enough for client devices such as laptops, smartphones, and tablets, to connect and maintain a reliable connection to the wireless network.<\/p>\n\n\n\n ESS-<\/strong> An ESS (Extended Service Set) is a wireless network consisting of multiple BSSs interconnected through a common DS, typically a wired ethernet network. In an ESS, multiple APs broadcast the same SSID, while each AP has a unique BSSID. An ESS enables roaming, allowing a wireless device to move from one AP to another without losing network connectivity. For example, when you are using a mall WiFi you only connect to the wireless network once. But as you move through a giant building, you are associating with a different AP depending on where you are standing. In an ESS, you will typically connect to another AP when they determine a neighboring AP can provide a better connection.\u00a0<\/p>\n\n\n\n DS-<\/strong> A DS (Distribution System) is the underlying infrastructure that interconnects multiple BSSs to form a unified ESS. Although wireless clients can communicate with an AP over the air using the 802.11 protocol, without a DS APs are unable to communicate with one another. The DS provides the communication path that allows APs to exchange traffic with one another and with the broader wired network. The DS usually consists of switches and cables to connect to the APs.\u00a0<\/p>\n\n\n\n DS Traffic Flow: <\/strong><\/p>\n\n\n\n Client > AP > DS > AP > Client\u00a0<\/p>\n\n\n\n IBSS-<\/strong> An IBSS (Independent Basic Service Set) which is also known as an \u201cad hoc network,\u201d is a decentralized wireless network architecture that allows network devices to communicate wirelessly with one another without the need for a central AP. Devices can talk directly with one another without a network infrastructure. IBSS is commonly used for temporary peer to peer connections, such as sharing files between two laptops.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":" Today I am going to talk about the structure of wireless networks such as SSID (Service Set Identifier), BSS (Basic Service Set), and ESS (Extended Service Set.)
