Abstract
A battery pack comprises an enclosure; a plurality of network nodes that communicate with each other inside the enclosure and that generate a unique radio frequency (RF) signature; and a special-purpose computer processor that compares an incoming channel impulse response (CIR) of the unique radio frequency (RF) signature corresponding to an incoming packet to a plurality of stored valid RF CIR signatures and executes a resemblance metric to accept or reject the incoming packet.
