What is service set identifier?

A Service Set Identifier (SSID) is a unique name assigned to a wireless local area network (WLAN) that distinguishes it from other networks. It allows users to identify and connect to the desired network among multiple available options. The SSID can be up to 32 characters long and is typically broadcasted by the wireless access point, making it visible to devices searching for Wi-Fi connections. Users can also configure their devices to connect automatically to a specific SSID when in range.
