A:Answer A Hotspot is a cellular connection. It is the ISP, Modem, and router all in one. You would need an Internet Service Provider, and they might require a modem or they might use an ONT, that you can pair this router with.
If a Company is offering Fiber Optic Service then they give you an ONT and likely a router… That router is interchangeable with this device.
If the company offering Cable where the upload and download speed are dramatically different from each other, then yes you would likely have a Cable modem / router combo they provide to you.
Ideally Fiber is the best solution available right now.
