Mobile display on TV without Wi-Fi?

We have an allotment and the (old) residents were against the fact that there's Wi-Fi… (you would not have to use it but no matter). But to my question: Is it possible to transfer the mobile phone display on the TV without WLAN? Would then follow me at home netflix follow download and then transferred from the phone to the TV… Does anyone know if that is possible?

Simply install W-Lan and hide the SSID.

If they ask you how you did that, you say magic

Alternatively HDMI

We had planned but outside there's no wireless connection…

What is the W-Lan connection.

and what about a repeater?

Also goes by cable.

Called MHL cable
