Walmart has unveiled plans to expand its deployment of ambient IoT technology across its supply chain.
In collaboration with Wiliot, Walmart aims to integrate millions of battery-free Bluetooth sensors—referred to as IoT Pixels—to effectively track pallets throughout its supply chain operations. The ambitious goal is to install a total of 90 million sensors by the end of 2026.
As one of the world’s leading omnichannel retailers, Walmart emphasizes that this partnership is “designed to dramatically enhance supply chain efficiency, inventory accuracy, and cold chain compliance.”
The technology is already operational in 500 Walmart locations, with plans for expansion to encompass 4,600 Walmart Supercenters, Neighborhood Markets, and over 40 distribution centers by 2026.
Tal Tamir, CEO of Wiliot, remarked that this nationwide deployment in the U.S. introduces “a new layer of digitalisation to Walmart’s supply chain.” This innovation provides real-time insights and automation capabilities that significantly boost efficiency, accuracy, and responsiveness.
Wiliot claims this initiative represents “one of the largest ambient IoT deployments to date,” presenting a vital new source of supply chain data to support Walmart’s growing use of AI technologies.
The collaborative technology is already yielding substantial benefits by reducing manual tasks and providing automated alerts. Furthermore, it enhances inventory visibility, resolves discrepancies, and ensures smoother operations, ultimately leading to improved customer experiences.
“With Wiliot’s ambient IoT technology, coupled with our AI systems, we’re not only optimising our supply chain to make faster, smarter inventory decisions, but we’re also tackling one of the hardest problems in retail—knowing exactly what we own and where it is at any given moment.”
