If a customer wants to broadcast a WLAN at a certain time and day of the week, SSID scheduling should be configured

According to the SSID Scheduling - Mist document1, SSID scheduling is a feature that allows you to customize your WLAN by choosing the exact days and times to broadcast the SSID. This feature can be useful for scenarios where you want to limit the availability of a WLAN to a certain time and day of the week.
