My experience with mobile hotspots is that they work just like having a DSL or cable connected wireless router. You don't need a separate router but you will want to make sure everything that connects to it is firewalled. The one I tried out earlier this year was even running Linux "under the hood."
I have had good luck with cellular modems and Cradlepoint routers.
