I am saying that when using wireless links, a node should be aware
that his communication could interfere with other communication.
Less powered is the transmission signal, less noise is seen by
neighbours.
It also means that it's more greatly affected by interference from
neighbors: there is no free lunch.
A low powered node will also need less energy to communicate in a
less noisy environnement.
In low-power wireless chipsets, CMOS dominates power costs. E.g., a
chip that draws 60mW transmits at 1mW. Reducing transmit power
typically does not conserve much energy.
