Low-Power Edge Device for Wireless Communication Range Extension

An enhanced, ultra low power passive wake-up radio-based sensor includes a passive wake-up radio-based sensor node having an energy harvester and low power wake-up circuit to improve the wake-up range for passive wake-up radio sensor nodes without the need for local power. The wake-up sensor may additionally include a transmitter for providing a wake-up signal to nodes that are outside the wake-up range of a base.
