A hidden Wifi display network is a wireless network that isn't broadcasting its network ID (SSID).
Typically wireless networks broadcast their name and your mobile listens for the name of the network that it wants to connect to. Because a hidden network doesn’t broadcast
your mobile can't find it so the network has to find your mobile. For this to happen
your mobile must broadcast both the name of the network it's looking for and its own name. In this situation
with Hidden wifi Display you can get acces to this taype of wifi.
