In this paper, we validate a novel augmentation to the PHYsical layer (PHY) of the IEEE 802.15.4 standard for wireless sensor networks. This augmentation implements interleaving and Forward Error Correction (FEC) encoding within the transmitting sensor nodes, facilitating a significant reduction in their transmission energy. We detail the design, parameterisation and implementation of this FEC encoder and show that is has only an insignificant energy consumption compared to the transmission energy reduction that it affords. Our analysis shows that net energy savings of 24.8 -- 31.4% can be achieved by the augmented PHY
