In wireless networks, ESSID refers to which concept?

• A. a wireless network that can utilize multiple WAPs to a broadcast network
• B. The encryption protocol
• C. The MAC address
• D. The channel

Answer: (A)

ESSID stands for Extended Service Set Identifier, which is the network name used to identify a wireless network that spans multiple access points. When several APs broadcast the same ESSID, they form an Extended Service Set, so devices see one single network name and can roam between APs as they move around. Each AP still has its own MAC-based identifier (BSSID), but the user-facing network name remains the same, enabling seamless coverage over a larger area. This concept is not about encryption protocols, MAC addresses themselves, or choosing a particular channel, which is why the other options don’t describe ESSID.
