You're not gonna harvest enough energy to transmit over LTE. I actually had a patent in energy harvesting. It's good for much lower power operations. My design here killshots the capacitor charge str...

LTE is not the only possible transport.
5G has some low power IoT mode and actually, why restrict ourselves to mobile networks?

You could just broadcast a Bluetooth beacon intended to be transported by devices on the find my network, which means basically any iPhone or android around can do the internet hop for you.

I still think LTE is the most likely attack vector, and there's a reason the attackers chose it. Even purpose-built "low-power" cellular IoT chips draw hundreds of milliamps during transmission, well within the detection envelope of the proposed circuit. Bluetooth is a more interesting counterargum...
