SSID Full Form

What Is The Full Form Of SSID?

The Full Form Of SSID is Service Set Identifier

The SSID is a 32 character unique ID and is used to provide a name to a wireless network. When a large amount of data travels in the network and when multiple wireless networks overlap at a certain location, there are high chances for the data to get lost. Thus, in such a situation, the SSID makes sure that such data should reach the proper and correct destination.

Sometimes, the SSID refers to a network name. When you have multiple independent networks existing in the same physical area, it helps to connect your device to a specific network. In the network, each set of devices communicating with each other is called (BSS) basic service set. When multiple BSS join, it forms one logical WLAN segment known as (ESS) extended service set. The ESS is given 1-32 byte alphanumeric names and is called (SSID) service set identifier.
