Meshcore.

I've been running trace routes all day on these three repeaters. Getting excellent and consistent results. There's a repeater to the east of St Charles that is 20km away and I'm not hitting it. There's a tall one that is 30km away and I hit it yesterday but never today.

So when planning your network, I strongly recommend a repeater about every 15km. I'm getting excellent results with repeaters that are 100ft 33m up.

Given that meshcore can support up to 64 hops, if you put a repeater every 10 miles that's 640 mile radius from your location. Plenty.

I'm also considering that repeaters placed less than 50ft should run a transmit delay.

I'm learning the lessons that cell phone providers learned... you need more and you need smaller cells.
