There are indoor 5G radio units for use in malls and large buildings (see Ericsson's Radio Dot products for example [1]). That's probably what they were thinkin

  Is that like a repeater or is there more to it?

    There is more to it. As I understand it (and please, correct me where I'm wrong, internet) as the frequency goes up, the range and ability to penetrate walls goes down. Each generation uses more spectrums, more ranges. So 5G is neat because it's got low frequencies with long-range towers in rural areas, but also high frequency short-range 'towers' in urban areas. This means instead of way too many people trying to share a limited spectrum over a huge area (IE: low frequency in the city), you can have short-range high frequency 'towers' every few hundred meters in a city. But now they're coming for our wifi routers, demanding that spectrum too. And that's kind of bullshit.

      Well to be fair, how many malls have you been in that actually have decent WiFi? The infrastructure already exists in the enterprise to provide it, but usually they cheap out at some point so it ends up being useless, and after going through the hoops to register and realise you are getting 500kbps, you switch to mobile data. If this ends up with large indoor areas (malls, airports, etc) having decent connectivity I'm all for it.

    An Ethernet cable plugs into the unseen side. Very similar to Wi-Fi but costs much more, is faster, does not require any user effort to connect, and is limited to just one telco's customers.
