ABSTRACT: Most of the published wake-up radios propose low energy design at the expense of reduced radio range, which means that they
require an increased deployment density of sensor networks. In this article, we introduce a design of a high sensitivity 916.5
MHz wake-up radio using low data rate and forward error correction (FEC). It improves the sensitivity, up to -122 dBm at a
data rate 370 bit/s. It achieves up to 13 dB of coding gain with symbol error rate (SER) 10-2, and up to 4 times the range of the data radio, rendering it more suitable to sensor networks. Our design can receive wake-up
signal reliably from any IEEE 802.15.4 transmitter and achieves a low packet error rate (PER) 0.0159 at SNR 4 dB. Furthermore,
our design encodes the node ID into a wake-up signal to avoid waking up the undesired nodes.
