just a note so we don't confuse the terms:

Marek means with "range" where the communication can practically succeed, even 
over multiple hops. As you have some probablity to lose packets on each
hop, the communication becomes "practically" unusable over very long
distances, e.g. >10 hops (depending on your network setup and
environment ...).
Note that this range is not the single-hop range.
