What is the primary purpose of an ESSID?

The primary purpose of an ESSID (Extended Service Set Identifier) is to represent the name of a single wireless network. This identifier allows devices to connect to the correct wireless network within the vicinity, distinguishing it from other networks that may be present. The ESSID acts as a network name that is broadcasted by access points to help users select the desired network.

While the ESSID may seem similar to a collective name for all wireless networks, it specifically refers to the name of an individual network rather than encompassing all networks in an area. Additionally, it does not serve the primary function of identifying individual devices on a network or being used exclusively for data encryption, as these functions are handled by other networking protocols and mechanisms.
