Solution Overview

Ambient IoT

As digital transformation and global sustainability goals accelerate, connecting billions of physical assets demands a fundamental breakthrough in power and cost efficiency. Ambient IoT (A-IoT) has emerged as a pivotal enabler to realize the vision of massive IoT. By harvesting cellular RF energy, the innovative solution eliminates the need for batteries or wiring, offering advantages over active solutions: maintenance-free, zero-carbon, and ultra-low cost. Unlike range-limited passive technologies, A-IoT leverages ubiquitous cellular networks to provide wide-area, reliable connectivity—offering a scalable, commercially viable, and green foundation for smart logistics, asset management, and energy monitoring.
