Definition — What is SSID and what it does?

You’ll often see the acronym “SSID” when wireless networks are involved. SSID is the name assigned to a wireless network.

For example, if you take your device to a coffee shop and you see a sign telling you to join a network with an SSID of “HotPot WiFi”, devices will look for all networks in range when you attempt to connect to local Wi-Fi, you just need to pull up the list of wireless networks nearby and join the “HotPot WiFi” network.

SSIDs can be up to 32 bytes long text string. They are also case-sensitive; "HOTPOT" is a different network than "hotpot".
