The abbreviation SSID stands for Service Set Identifier. This is the unique name that identifies a wireless network. It is in the packet header when a data packet is transmitted. The devices on the Wi-Fi network use this identifier for communications via the network. The name is up to 32 alphanumeric characters in length and case sensitive. A company in one physical location may have several WLANs, and that means the business will also have wireless access points using different SSIDs.

Beaconing or SSID Broadcasting

A wireless network access point will broadcast its availability using its service set identifier. This SSID broadcast displays the Wi-Fi network name, though access to the network can be limited through security measures. The broadcasting of an SSID may also be called beaconing. Password-protected wireless networks broadcast the SSID but require the correct password for network access. SSID broadcasting can also be disabled, when required.

A Service Set Identifier Is the WLAN Name

The wireless network name, the Service Set Identifier, is the reason that data is delivered to the proper destination. The SSID differs from a router name. When looking for a wireless network, users will usually see the router or station name, which should not be confused with the 32-character SSID. Every packet that moves over a WLAN has the network service set identifier. Without this identification, data delivery might not reach the correct destination when multiple wireless networks are operating in one area.
