Hotspot which can connect to either 4G or Wifi
I own a camper which is going to be installed with IOT devices shortly for heating, security and general internet access on the move.
I am looking for a device which can share internet access to the IOT devices, using Wifi first but then opting to use 4G network if no Wifi is found. The idea is when I’m on a campsite/resort with Wifi I will use that, but when wild camping or on the move, the 4G steps in.
Web searches don’t appear to find anything obvious and I wonder if its the terminology I’m using as the moment you say hotspot and wifi it presumes that you need wifi so as to be a wifi client when I want to use wifi in and wifi out of the device effectively.
Does such a product exist?
