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.
