Spreading factor affects how far apart the radio's transmissions
are, across the available bandwidth. Radios with different spreading
factors will not receive each other's transmissions. This is one way you
factors will not receive each other's transmissions. This is one way you
can filter out radios you want to ignore, without making an addressing scheme.
Spreading factor affects reliability of transmission at high rates, however,
so avoid a hugh spreading factor when you're sending continually.
