I want to use a RUT-955 in my campervan, I am hoping to use it for connecting to both 4G and wifi hotspots. My external antenna on the roof of my van has 2x4G cables and 2xWiFi cables, if I connect these to the RUT955 I don't understand how I will get the wifi inside the van, am I missing something? it seems that I will also need an antenna inside the Van in order to get wifi inside? so I also need some sort of wifi device or am I limited to only using the RUT955 with the RJ45 ports?
