This sounds like what RNode devices for Reticulum networks appear to be able to do. (I haven't tried it for myself yet.)

> RNodes can be made in many different configurations, and can use many different radio bands, but they will generally operate in the 433 MHz, 868 MHz, 915 MHZ and 2.4 GHz bands. They will usually offer configurable on-air data speeds between just a few hundred bits per second, up to a couple of megabits per second.

> [...]

> While speeds are lower than WiFi, typical communication ranges are many times higher. Several kilometers can be acheived with usable bitrates, even in urban areas, and over 100 kilometers can be achieved in line-of-sight conditions.

> Reticulum is the cryptography-based networking stack for building local and wide-area networks with readily available hardware. Reticulum can continue to operate even in adverse conditions with very high latency and extremely low bandwidth.

That does look fascinating. I hadn’t seen this yet, thank you.
