[RC232] Maybe you have some documents or test reports about the influence of the data rate to the range in the same system?

There are some general rule of thumbs that can be used.

Doubling the data rate give 3dB less sensitivity.
4x data rate give 6 dB less sensitivity.

6 dB less sensitivity is used as approximate 50 % range.

2.4 kb/s = x meters
9.6 kb/s = x/2 meters
38,4 kb/s = x/4 meters
