You did not ask me :)
The formula you are referring to was posted by somebody else.
Also, to repeat, I am warning against calculating a "transmission range"
for wireless communications. How far you can send in theory has
absolutely no relation to how far you can send on a moderately busy
channel. This effect *is* modeled in Veins!
If you want to know more, you can do a small simulation study to
investigate packet reception rate vs. distance vs. channel load. The
results should tell you all you need to know.
Best,
Christoph
