For two devices communicating at ground level, you can expect a half mile to about a mile.

If you can get connected to a router, though, at some height, you can get a seriously good distance.

There's a guy in my local area who's 17 miles away who had his node 30 feet up on a pole and was communicating with our router 200 feet up on a tower from 17 and a half miles away.

I think the farthest achieved distance is over 300 km, mountain top to mountain top.

As far as bitrate goes, the default long fast is like 1.9 kbps and I think the short fast is like 10 kbps. There's a faster setting called Short Turbo, that's like 20K BPS, but it's not available in all regions due to legal restrictions, so I don't count it.
