Wake-up radio ranges: a performance study
Wake-up radio technology helps to attenuate unnecessary power consumption by allowing a node to keep its main radio off until it is woken up by a signal to an auxiliary low-power radio receiver. In this paper, we evaluate the range performance of an ultra-low power wake-up radio receiver (WuR) integrated into a wireless device suitable for wireless sensor networking deployments. We run several ranging experiments, both indoors and outdoors, where a transmitter sends wake-up sequences to a receiver positioned meters away.
