By works I mean, doesn't cut out permanently and from then on at every small hill or rise in the ground. I've done a lot of real implemention of 900 MHz and 2.4 GHz mesh wireless networks.

I currently operate a 5 MHz channel at 910 MHz using broadband hamnet firmware on ubiquiti transceivers. This is for between home (custom antenna up on a tall 10m pole on my apartment) and my car (custom antenna popping up through the sunroof). By work, I mean, work at all for more than the first slight change in elevation. I've even tried using custom FPV narrowband solutions (56k SLIP) at 433 and 900 MHz and those do not better. The first slight rise in the ground kills you after a block or two. And I'm not in a super-hilly region.

I have no confidence than any ad-hoc deployed mesh network of 2.4 GHz is going to be good for anything but within a single home or building.
