As we saw in the examples given earlier, PoW made identity forgery very impractical providing a mechanism to protect network participants fom Sybil attacks. The idea of NBPoW is to use the EM sprectrum in scenarios where radio waves are involved such as Wifi of Lifi, to control the way nodes interact with each others. This can be done because of the wat in which radio waves based networks work: the amount of neighbors you can have on a given location of the spectrum is limited and to take their place, as an attacker would want to do, is not easy at all.
