Razer Sila

I have a question.
Being in Australia and having a modem where if the internet does for some reason drop out, the current modem that i have would instantly revert to the 4G network. (Yes, i know, we are miles behind the rest of the world, but that is the price you pay for being so isolated from everyone else.)
Now, if the modem would kick into 4G, how would the Sila cope with the network, and will it be able to cope with the speeds at all??
Just asking, since i need to put it into the pc room, as the WIFI in that area of the house is a bit shit. In turn, it would allow me to utilise the WIFI outside in the front of the joint as well, blaring music while the street has a bonfire and a massive drinking session.
