WhatsAppPower interface is just a fancy name for the connector RJ45. During detection, PSE is sending a series of low-voltage pulses of different levels within the so-called detection range, which is between 2.70 V and 10.1 V. If the PSE is designed to provide power over four pairs in the cable, it has to do detection on both pairsets.
