Signal through walls

Wondering if anyone has experience flying behind concrete walls / in caves / other dense signal-blocking materials? I'd like to explore some old mines, caves, and brick buildings without being inside (due to legal and physical dangers). How well does Tello's signal punch through rock and concrete? Does adding a wifi extender help?

Thanks!

Tello splelunking? Gutsy. (y)

Extender may help but would be more leery of low light environment, uniform surfaces and over bodies of water.

Check this out. No description of setup though.

Oh that's fun. Follow up question: what kind of wifi extender and how do they work with Tello?

One of many threads on extender/repeaters. Start with this:
