Why is SSID broadcast important in wireless networks?

The importance of SSID broadcast in wireless networks primarily lies in its role in making the network visible for clients to connect. When SSID broadcasting is enabled, the network's identifier (SSID) is transmitted as part of beacon frames and can be detected by wireless clients in the vicinity. This visibility allows clients to see the network when scanning for available connections, making it easier for users to join the network without needing to manually enter the SSID.

When networks do not broadcast their SSID, they become hidden, which can create connectivity challenges for users who are trying to access the network, as they must know the exact SSID to connect. While some might consider hidden SSIDs to be more secure, this method does not actually prevent unauthorized access and can complicate legitimate user connections. Thus, broadcasting the SSID facilitates a straightforward connection process for authorized users and enhances the overall user experience when accessing the network.
