What does SSID stand for in the context of WLAN?

SSID stands for Service Set Identifier. It is a unique identifier assigned to a wireless local area network (WLAN) that distinguishes one network from another. The SSID allows devices to connect to the correct network among multiple wireless networks that may be in the vicinity. Typically, the SSID can be up to 32 characters long and can include alphanumeric characters and special symbols.

Using the SSID, users can easily identify and connect to their preferred wireless network, which is essential for both security and ease of access. When devices scan for available networks, they display the SSIDs, allowing users to choose the one they wish to connect to.

In the context of wireless communications, understanding the distinction and purpose of SSIDs is crucial for effective network management, troubleshooting, and ensuring secure connections.
