AT&T and Wiliot are expanding their collaboration around Wiliot’s Physical AI platform, with AT&T taking on systems integration, field deployment, device certification and operational support roles for enterprise supply chain environments.

For enterprises trying to digitize supply chains, the hardest part is often not collecting one more data point. It is building a repeatable operating model that can place sensing infrastructure across warehouses, vehicles, stores and distribution centers without turning every deployment into a custom engineering project.

That is the significance of Wiliot’s expanded work with AT&T Business. The announcement is less about a conventional connectivity resale arrangement and more about formalizing how Wiliot’s battery-free sensing platform can be installed, certified, operated and potentially delivered as part of AT&T’s enterprise service portfolio.

Wiliot describes its platform as Physical AI: a supply chain intelligence layer based on battery-free IoT Pixels that capture real-time information such as location, temperature and other attributes from physical goods and assets. AT&T’s role is to provide network infrastructure, cellular connectivity and the field execution needed to deploy and maintain these systems in large enterprise environments.

More than a connectivity agreement

What makes this collaboration distinct from many IoT carrier announcements is the distribution of responsibilities. AT&T is not simply providing wide-area connectivity for devices. According to Wiliot, the companies have moved toward a systems integration and device certification model, with AT&T supporting design, installation, asset tagging and ongoing maintenance across active deployments.

That distinction matters because Wiliot’s IoT Pixels are battery-free Bluetooth sensors, not cellular endpoints. In practical terms, cellular connectivity enters the architecture through gateway devices and the supporting network layer rather than through a SIM embedded in every tracked item. The work to certify Wiliot-ecosystem gateways on AT&T’s network is therefore a critical operational step: it can reduce deployment variability and give enterprises a more standardized path for connecting ambient IoT infrastructure back into cloud and enterprise systems.

The companies say this field model has already been used across multiple enterprise environments, including retailers, food and beverage companies and quick-service restaurants. Wiliot also says its platform is deployed across tens of thousands of sites and is approaching hundreds of millions of actively tracked assets, while working with the majority of Fortune 50 companies that have active supply chain initiatives.

Wiliot cites operational results from its deployments, including inventory accuracy of 99% or more, dock-to-stock time reductions from 24-48 hours to 2-6 hours, receiving labor reductions of 30-50%, mis-shipment reductions of up to 90%, and reductions in lost, damaged and delayed packages of 60%. As with all vendor-reported metrics, these should be read in the context of specific deployment conditions, but they indicate the type of process-level outcomes the platform is being positioned to address.

Why this matters for IoT providers

The broader relevance for the IoT ecosystem is the shift from device connectivity toward managed physical-world data operations. Supply chain visibility projects have long struggled with fragmented scanning processes, fixed RFID read points and inconsistent asset-level data. Wiliot’s model aims to create continuous, scan-free data streams from inventory and reusable assets, while AT&T brings the deployment and network operations capabilities required to make that model usable across distributed enterprise footprints.

For OEMs and gateway vendors, certification on AT&T’s network could become a practical requirement if they want to participate in Wiliot deployments delivered through AT&T-led enterprise programs. For systems integrators, the announcement signals that large carriers may increasingly compete for roles that extend beyond connectivity into installation, maintenance and monitoring of edge infrastructure.

Enterprises and industrial operators may see the most immediate impact in procurement and operations. Instead of assembling separate vendors for tags, gateways, cellular service, site surveys, installation and post-deployment support, customers could potentially engage through a more integrated delivery model. That does not remove integration complexity, particularly around enterprise workflows and data consumption, but it does address one of the recurring bottlenecks in scaled IoT adoption: who is accountable for making the physical deployment work across many sites.

AT&T and Wiliot are also exploring a longer-term path in which Wiliot-generated data becomes part of AT&T’s enterprise offerings. If that develops, the collaboration would position supply chain sensing data as a service layer on top of network infrastructure, rather than as a standalone IoT project. For the carrier market, that is an important signal: value is moving from connecting assets to operationalizing the data those assets produce.
