1. An apparatus comprising:
a plurality of antennas;
a plurality of Front End Modules (FEMs) coupled to the antennas;
an input for receiving Power over Ethernet (PoE);
a PoE detector for identifying a type of PoE received at the apparatus, wherein said type of PoE is associated with a PoE power budget; and
a power controller for applying a PoE power conservation policy based on said PoE power budget;
wherein applying said PoE power conservation policy comprises switching between a normal operating voltage and a reduced operating voltage at the FEMs, wherein the reduced operating voltage continues to apply power to the FEMs.
