TV can see through walls

Just toss a doppler laser interferometer on a window, mirror, etc. At least with fiber-optics you need physical access. Single mode (I think that's most of FTTH) is pretty insensitive to vibration and hard to localize so you'd really have to install something.

Ah, but of course. How could I forget about my trusty pocket doppler laser interferometer!

Yours is not built in to your watch? You should go and have words with Q.

This is a "high school project funded with pocket money" level of DIY, with €25 of parts.

Microwave beam-forming says what?

I didn’t hear it say that. I guess I’m not the target. :P

You'll need that to intercept fibers as well, plus a pocket fusion splicer to boot!

In this context, is line of sight with the ability to emit and receive laser radiation at the target not ‘physical access’?

Not for an exterior window.
