I have the Verizon MiFi and it uses cell data and creates a WiFi network for the rig and at home. Easy to use but you get the monthly bill. We use it for 2 laptops, a tablet and printer, all wireless. Ditto for the same capability from a phone.
Information in the above link will allow you to use much more distance WiFi locations if they are free or you have their password. I'm considering one set of hardware for under $200 for those times when for various reasons I don't want to use the MiFi.
