Hoi Miguel, I have aligned the antenna in the direction of the radio mast (location of the radio masts in the online portal).
The antenna has a LAN with POE (power connection) and SIM slot. The best way to program the antenna is via the Zyxel App. The antenna only has WLAN for programming for the mobile, not for Google! To do this, order a TP Link router and then set up a WLAN. Are the answers helpful? Greetings Michel

Zyxel Air App. And Google "Name of your SIM card supplier" and tower near city postcode.
