That is consistent with both scenarios that I suggested.
wifi does not mean hotspot, portable or otherwise. Wifi is simply local wireless communication - nothing to do with internet. Hotspot generally means a place where internet is provided. A portable hotspot is a device that typically has cellular WAN capability and wireless LAN capability.
the type of travel router being discussed typically has wireless WAN capability (sometimes wired as well) and wireless LAN capability. No cellular involved/no internet of its own.
