Hot spot integration to existing WiFi ?

    Has anyone explored using your T-Mobile hot spot wireless router and integrate it with an existing home WiFi router system. The T-Mobile device apparently does not have a Ethernet output that one could plug into existing router....any ideas?  Reason for wanting to do this is that my existing Ubiquiti WiFi system connected to my current ISP is customized system that broadcasts through 3  transmitters needed to cover my large area.  My ISP is not only expensive but slow (10 mbps) goes down when the local grid goes down.  Thought about dumping that system (and loose the many security and analytics functions)  and possibly using a repeater in conjunction with the T-Mobile hot spot device (router)
