What is the purpose of an SSID?

SSID, which stands for Service Set Identifier, serves as a way to identify and distinguish wireless networks. The primary purposes of an SSID is to identifies a WLAN. An SSID is a unique name assigned to a wireless network. It helps users identify and select the specific network they want to connect to from the list of available wireless networks in their vicinity.

In areas with multiple wireless networks, each network typically has a different SSID. This differentiation prevents devices from accidentally connecting to the wrong network and helps users choose the correct network based on their intended access.

Different SSIDs can be used to separate and isolate wireless networks. For example, a home router might have a default SSID for the primary network and a separate SSID for a guest network. This segregation allows users to control access and apply different security settings to each network.
