Why is it called SSID?

The term SSID stands for Service Set Identifier. It is the name given to a wireless network, which is used to identify and differentiate it from other networks in the vicinity. The SSID is essentially a unique identifier that allows devices to connect to a specific wireless network.

The term “SSID” was coined to describe this identifier because it serves as a means of identifying and distinguishing different wireless networks. It is similar to how a person’s name helps us recognize and differentiate them from others.

Think of it this way – when you walk into a crowded room, you may notice several people, but you can easily identify and call out a specific person by their name. Similarly, when you search for available Wi-Fi networks on your device, you see a list of network names or SSIDs, and you can select the one you want to connect to.

The SSID is broadcasted by wireless routers or access points, allowing nearby devices to detect and connect to the network. It is important to note that the SSID by itself does not provide any security to the network. It is merely a label that identifies the network. To secure the network, additional measures such as encryption and password authentication are required.

The SSID can be chosen by the network administrator during the initial setup of the wireless network. It can be any combination of letters, numbers, and symbols, typically limited to a certain length. The administrator may choose a name that reflects the purpose or location of the network, making it easier for users to identify and connect to the correct network.

For example, a coffee shop may set its SSID as “CoffeeShopWifi” so that customers can easily identify and connect to the Wi-Fi network provided by the establishment. In a residential setting, the SSID could be something like “SmithFamilyNetwork” to indicate that it belongs to the Smith family.

Having a unique SSID is particularly important in areas where multiple wireless networks are available. Without a distinct identifier, it would be challenging for users to determine which network is theirs or which one they intend to connect to.
