Have a look at meshmap.net. That shows people who have voluntarily put themselves on a map.
Although it can be a serious underestimation, for example in my area, I'm the only one who lists myself on the map, but there are about 10 other nodes that don't
Edit: Also, the number of nodes on MeshMap has pretty much doubled in six months since I started playing with it.
Hmm, more than I expected actually. None in my town but one in a nearby town and the nearest city.
Is there a limit to how far can you communicate through multiple nodes? Also is there anything special for setting up a repeater compared to just communicating on the network?
Though i don't know anyone else that would be likely to use something like this sadly.
They've set the maximum at seven hops, but depending on weather conditions, that can easily be several hundred miles.
Nothing special is needed for a repeater except that you probably will want a node with a solar panel such as the seeedStudio solar. You would put it up as high as you can get it. I generally say if it's more than 100 feet in the air, use router mode. If it is less than 100 feet but above 20 feet, use client. If it is less than 20 feet, use client mute.
Your node in your pocket or in your car should be on client mute mode since them broadcasting will not get the signal much farther and will just cause more channel utilization on high nodes.
Nice, 0 within 25 kilometers of me lol.
Remember, that map is volunteer and only shows nodes of a day or less.
For example, I am the only node in my area who voluntarily puts myself on the map, but there are 10 others who do not.
