Ultra Wideband Technology: Redefining Precision In Asset Tracking

Ultra-Wideband (UWB) is a radio frequency technology operating across a wide spectrum from 3.1 to 10.6 GHz. It functions by transmitting extremely short bursts of radio energy, typically lasting only a few nanoseconds. This pulse-based transmission enables precise distance measurement through techniques such as Time-of-Flight (ToF) and Time-Difference-of-Arrival (TDoA). ToF measures the time taken for a signal to travel between two UWB devices, while TDoA calculates location based on the differences in arrival times of a UWB signal at multiple fixed reference points. UWB technology is standardized under IEEE 802.15.4, with amendments 802.15.4a and 802.15.4z specifically enhancing its ranging capabilities with added security and robustness.

UWB systems provide highly accurate, real-time positioning data, particularly effective in indoor environments where Global Positioning System (GPS) signals are often unavailable or degraded. This capability renders UWB valuable in sectors requiring spatial awareness, including manufacturing, healthcare, and logistics.

Technical Characteristics

Frequency Range: 3.1 GHz to 10.6 GHz. The wide bandwidth allocated to UWB allows for the transmission of very short pulses, which is fundamental to its precise ranging capabilities. Regulatory bodies, such as the Federal Communications Commission (FCC) in the United States, permit UWB operation within this spectrum under specific power limits to ensure compatibility with other radio services.
Pulse Duration: Nanosecond-scale. The brevity of these pulses minimizes the impact of multipath interference, a common challenge in indoor environments where signals reflect off multiple surfaces. This characteristic enables UWB to resolve closely spaced signal paths, contributing to its high accuracy.
Location Accuracy: Typically 10–30 cm. This level of precision is achieved through the ability to timestamp UWB signals with sub-nanosecond resolution, directly translating to highly accurate distance calculations.
Core Standards:

IEEE 802.15.4: This foundational standard specifies the physical layer (PHY) and media access control (MAC) for low-rate wireless personal area networks (LR-WPANs).
IEEE 802.15.4a: This amendment introduced precise ranging capabilities to the standard, primarily through the analysis of the UWB signal’s Channel Impulse Response (CIR). This allows for high-resolution time measurements essential for accurate distance determination.
IEEE 802.15.4z: This amendment further enhanced UWB ranging by adding secure time-of-flight measurements and improving robustness. It includes cryptographic protection of ranging measurements to mitigate vulnerabilities such as spoofing and relay attacks, thereby increasing the integrity and trustworthiness of location data.

Industry Ecosystem:

The FiRa Consortium is an industry alliance dedicated to promoting interoperability and the widespread adoption of UWB technology across various applications. Member companies include Samsung, Bosch, Cisco, and NXP, among others.

UWB systems exhibit greater resilience than signal strength–based solutions like Bluetooth Low Energy (BLE) or Radio Frequency Identification (RFID), particularly in environments characterized by high levels of interference or the presence of metallic obstructions. This resilience is attributed to UWB’s wide bandwidth and low power spectral density.

Deployment Considerations

Parameter
Details

Infrastructure
UWB Real-Time Location Systems (RTLS) necessitate the deployment of fixed UWB anchors and mobile UWB tags. Anchors serve as reference points, often powered via Power over Ethernet (PoE) or battery, strategically placed within the tracking area.

Tags
UWB tags are battery-operated devices attached to assets, equipment, or personnel to be tracked. Their low duty cycle operation typically enables battery lifetimes ranging from 3 to 5 years, reducing maintenance requirements. Tag form factors vary based on application needs.

Software
UWB location data requires integration with various enterprise software systems. This includes Enterprise Resource Planning (ERP) for asset management and inventory reconciliation, Warehouse Management Systems (WMS) for optimizing picking paths and inventory flow, and Manufacturing Execution Systems (MES) for tracking work-in-progress materials and personnel within production environments. Integration with analytics platforms provides operational insights.

Cost
The overall cost of a UWB system deployment varies depending on the scale of the implementation, the size and layout of the facility, the desired accuracy level, and the density of anchors required. Specialized UWB components and installation labor contribute to the initial investment.

Security
UWB systems employ features from IEEE 802.15.4z for enhanced security. This includes cryptographic protection of ranging measurements and secure timestamping mechanisms. These features are designed to prevent malicious interference such as spoofing, relay attacks, and unauthorized access to location data.

Verified Real-World Implementations in Logistics

These use cases demonstrate UWB’s application and measurable impact within supply chain logistics:

Warehouse Optimization – Pozyx’s UWB solution was implemented at Bonduelle, a processed vegetable producer, to address the challenge of locating pallets in their large fresh salad factory. By leveraging real-time UWB tracking of pallets, the company achieved a 3% increase in warehouse efficiency. This precision in localization reduced manual search times, resulting in hundreds of hours saved annually per warehouse.
Employee and Forklift Tracking in Warehouses – Navigine deployed a UWB-based real-time tracking system across a 10,000 m² logistics warehouse. Employees and forklifts were equipped with UWB tags, enabling their precise location tracking. This implementation led to a 4% increase in daily task completion per employee and a 3% increase in overall warehouse productivity through optimized routes and workflow monitoring. Furthermore, the system integrated a collision prevention feature, enhancing worker safety within the operational area.
Real-time Goods Receipt and Transport Optimization – TB International collaborated with Inpixon/INTRANAV to integrate a smart warehouse module incorporating both RFID and UWB technologies. This multi-RTLS approach enabled precise localization with UWB and item identification with RFID. The system automated goods receipt processes, provided digital work instructions for sorting operations, and optimized transport orders for forklifts based on real-time location data. These improvements collectively resulted in a nearly 40% increase in operational efficiency, including scannerless storage and retrieval processes.

Standards and Ecosystem

IEEE 802.15.4 This is the foundational standard for low-rate wireless personal area networks (LR-WPANs), upon which UWB operates. Key amendments to this standard have specifically evolved UWB’s capabilities:

802.15.4a: This amendment introduced specific provisions for high-resolution ranging and location capabilities for UWB. It defines mechanisms for more accurate time-of-flight measurements by analyzing the UWB signal’s Channel Impulse Response (CIR).
802.15.4z: This amendment builds upon 802.15.4a, focusing on secure UWB ranging and enhanced robustness. It integrates cryptographic techniques to protect ranging measurements from manipulation and improves the reliability of ranging in challenging radio environments.

FiRa Consortium The FiRa Consortium is an industry alliance established to ensure interoperability among UWB devices from various manufacturers. Its activities include the development of common technical specifications, the establishment of certification programs, and the promotion of UWB technology for secure ranging and precise location. This concerted effort contributes to the growth and diversification of the UWB ecosystem, facilitating broader adoption across industries.

Limitations of UWB

Higher initial hardware and installation cost: Compared to technologies like BLE or passive RFID, UWB systems typically incur higher upfront costs. This is due to the specialized nature of UWB transceivers, antennas, and the precise calibration required for anchor placement during installation.
Tag size and cost may not suit very small or low-value items: The size and unit cost of current UWB tags, driven by component size and battery requirements, can render them impractical for tracking extremely small or disposable, low-value items where cost per tag must be minimal.
Performance may be affected in environments with dense physical obstructions: While generally robust, UWB signal propagation can experience attenuation or severe multipath effects in environments with numerous dense metallic structures or thick concrete walls. This may necessitate a denser deployment of anchors to maintain desired accuracy.
Integration with business software systems is necessary for full ROI: The raw location data generated by a UWB RTLS requires processing and integration with existing enterprise systems (e.g., WMS, ERP, MES) to transform it into actionable insights and enable automated workflows. This integration process can represent a significant portion of the total project cost and complexity.

Ultra-Wideband technology provides precision in indoor asset tracking capabilities. Its technical characteristics, supported by IEEE standards and fostered by the FiRa Consortium, position UWB as a solution for applications requiring accurate, real-time spatial awareness. From logistics terminals to industrial sites, UWB facilitates advanced automation, enhances safety protocols, and contributes to operational efficiency. Verified implementations in supply chain logistics underscore its application in optimizing material flow, improving productivity, and ensuring worker safety.

Walmart Ai Pricing Patents Signal Shift Toward Real Time Retail Execution

Walmart’s new patents and digital shelf rollout point to a more tightly integrated model linking demand forecasting, pricing, and store-level execution.

Walmart has secured two patents related to automated pricing and demand forecasting, drawing attention to how large retailers are evolving their pricing and execution capabilities.

One patent, System and Method for Dynamically Updating Prices on an E-Commerce Platform, covers a system that can dynamically update online prices based on changing market conditions. A second, Walmart Pricing and Demand Forecasting Patent Classification, relates to demand forecasting technology designed to estimate what customers will buy and recommend pricing accordingly. At the same time, Walmart is expanding digital shelf labels across its U.S. stores, replacing paper labels with centrally managed electronic displays.

Individually, none of these elements are new. Retailers have long used forecasting models, pricing tools, and store execution processes. What is notable is the combination.

Walmart now has three capabilities aligned:

Demand forecasting tied to predictive models

Price recommendation based on that demand

Store-level infrastructure capable of rapid execution

That combination reduces the operational friction historically associated with pricing in physical retail.

Pricing Moves Closer to Execution

Traditional store pricing changes required coordination across multiple steps: analysis, approval, printing, distribution, and manual shelf updates. That process introduced delay and inconsistency.

Digital shelf labels materially change that constraint. Prices can be updated centrally and executed across stores with significantly less manual intervention.

This does not change the underlying logic of pricing decisions. Retailers have always adjusted prices based on demand, competition, and margin targets. What changes is the speed and consistency of execution.

As a result, pricing moves closer to real-time operational control.

Implications for Supply Chain Operations

Pricing is not an isolated commercial function. It directly influences demand patterns, inventory flow, replenishment timing, and markdown activity.

When pricing becomes faster and more responsive, those linkages tighten.

Three implications are clear:

1. Increased Execution Speed
Retailers can align pricing decisions more quickly with current demand conditions, reducing lag between signal and action.

2. Stronger Dependence on Forecast Accuracy
When pricing recommendations are driven by predictive models, the quality of demand sensing becomes more consequential. Forecast errors can propagate more quickly into sales and inventory outcomes.

3. Closer Coupling of Merchandising and Supply Chain
Pricing decisions influence demand. Demand impacts inventory, replenishment, and store execution. Faster pricing cycles compress the distance between these functions.

Centralization and Control

Walmart has positioned its digital shelf label rollout as an efficiency and accuracy initiative. Centralized price management improves consistency between systems and store execution while reducing labor tied to manual updates.

That positioning aligns with the operational realities of large-scale retail. At Walmart’s footprint, even small improvements in execution efficiency translate into material cost and accuracy gains.

At the same time, the shift toward algorithm-supported pricing introduces standard enterprise control requirements. Organizations need clear governance around how pricing recommendations are generated, reviewed, and executed, particularly as systems become more automated.

A Broader Technology Pattern

Walmart’s patents are best understood as part of a broader shift in supply chain and retail technology.

AI and advanced analytics are moving closer to operational decision points. Forecasting models are no longer confined to planning environments; they are increasingly connected to systems that can act.

In this case, that connection spans:

Demand sensing

Price recommendation

Store-level execution

The result is a more tightly integrated operating model in which commercial decisions and supply chain execution are linked through software.

What This Signals

The significance of Walmart’s move is not tied to public debate over surge pricing scenarios. The underlying development is structural.

Retailers now have the ability to connect demand forecasting, pricing logic, and execution infrastructure into a faster decision loop.

For supply chain leaders, that represents a clear direction:

Execution is becoming more digital, more centralized, and more tightly coupled to predictive models.

The companies that benefit will be those that can align forecasting, pricing, and operational execution within a controlled, coordinated system.

This week’s installment of Supply Chain and Logistics news includes stories about record increases in oil prices, Rivian’s autonomous taxis, and much more. Firstly, the Trump administration has issued a 60-day waiver of the Jones Act, a century-old regulation that requires goods moved between US ports to be transported by US-built vessels, etc. Additionally, this week Uber & Rivian announced a partnership for Rivian to build 50,000 autonomous robotaxis by 2031 with over a billion dollars in investment from Uber. Schneider Electric and EcoVadis announced a partnership to target emissions in the health care sector. Lastly, DHL announces 10 warehousing sites to be used for data center manufacturing capacity, and Mind Robotics raises 100 million in series A funding.

Your Biggest Stories in Supply Chain and Logistics here:

Trump Administration Issues Pause on Century-old Maritime Law to Ease Oil Prices

The Trump administration has issued a 60-day waiver of the Jones Act. This century-old regulation typically requires goods moved between US ports to be carried on vessels that are US-built, US-owned, and US-crewed. However, with oil prices surging toward $100 a barrel due to escalating conflict in the Middle East, the suspension aims to ease logistics for vital commodities like oil, natural gas, and fertilizer. While the move is intended to lower costs at the pump and support farmers during the spring planting season, it has sparked a debate between those seeking immediate economic relief and domestic maritime unions concerned about the long-term impact on American shipping and labor.

Uber and Rivian Partner to Deploy up to 50,000 Fully Autonomous Robotaxis

Uber and Rivian have announced a massive strategic partnership that signals a major shift in the future of autonomous logistics and urban mobility. Under the terms of the deal, Uber is set to invest up to $1.25 billion in Rivian through 2031, a move specifically tied to the achievement of key autonomous performance milestones. The primary focus of this collaboration is the deployment of a specialized fleet of fully autonomous R2 robotaxis, with an initial order of 10,000 vehicles and an option to scale up to 50,000 units. From a supply chain perspective, this represents a significant commitment to vertical integration; Rivian is managing the end-to-end production of the vehicle, the compute stack, and the sensor suite, including its in-house RAP1 AI chips, while Uber provides the scaled platform for deployment. Commercial operations are slated to begin in San Francisco and Miami in 2028, eventually expanding to 25 cities globally by 2031.

Schneider Electric and EcoVadis Announce Partnership to Decarbonize Global Healthcare Supply Chains

Schneider Electric, a major player in the digital transformation of energy management and automation, and EcoVadis, a provider of business sustainability ratings, have announced a strategic partnership aimed at accelerating decarbonization within the healthcare industry. “Energize” is a collective initiative to engage pharmaceutical industry suppliers in climate action. The collaboration focuses on addressing Scope 3 emissions, those generated within a company’s value chain, which often represent the largest portion of a healthcare organization’s carbon footprint. By combining Schneider Electric’s expertise in energy procurement and sustainability consulting with EcoVadis’s supplier monitoring and rating platform, the partnership provides a structured pathway for pharmaceutical and medical device companies to transition their global suppliers toward renewable energy.

Mind Robotics, a Rivian spin-off, raises $500 million in Series A Funding

RJ Scaringe, CEO of Rivian, is positioning his new $2 billion spin-off, Mind Robotics, as a technological solution to the chronic shortage of manufacturing labor in the Western world. By developing a “foundation model” that acts as an industrial brain alongside specialized mechatronic bodies, the company aims to move beyond the rigid, fixed-motion plans of traditional robotics toward systems capable of human-like reasoning and adaptation. Scaringe emphasizes that while these machines must perform with human-level dexterity, they don’t necessarily need to be humanoid in form; instead, the focus is on creating a data-driven “flywheel” within Rivian’s own facilities to lower production costs and help domestic manufacturing remain globally competitive.

DHL Expands North American Logistics Infrastructure Amid Growing Global Demand for Data Center Logistics Services

DHL is significantly scaling its data center logistics (DCL) footprint in North America, announcing the addition of 10 dedicated sites totaling over seven million square feet of warehousing capacity. This expansion is a direct response to the explosive demand for AI-driven infrastructure and the specific needs of hyperscale and colocation data center operators. By offering specialized services like rack pre-configuration, white-glove handling of sensitive IT hardware, and warehouse-to-site transportation, DHL is positioning itself as an end-to-end partner in a sector where 85% of operators express a preference for a single logistics provider. This move not only addresses the logistical complexities of moving high-value components like GPUs and cooling systems across global borders but also underscores the critical role of integrated supply chains in maintaining the build speed of the digital backbone.

How To Capitalize Quickly To Address Hyperconnected Industrial Demand

This first in a blog series offers a review of discussion that occurred during ARC Advisory Group’s 2026 Industry Leadership Forum. Specifically, it details a keynote conversation held with senior executives from Rolls-Royce, BTX Precision, and MxD.

The New Fabric of Demand: Modernizing Collaboration and Transparency for Real-Time Production

Industrial leaders have been talking about tearing down workflow and data silos for decades. Yet here we are again. For most, the reality is that most operations and supply chains today typically don’t indicate much progress. A few leaders have figured out how to use digital tools to scale and build pathways forward, a whopping 12.9% according to our latest data (yes, that’s sarcasm). However, even as they struggle to coordinate, orchestrate, and innovate across their operations and enterprise, much less tightly collaborate outside their four walls. In a digital world, this continued capability gap, the inability to closely link market signals to responsive production and external supply chains, is very quickly becoming a liability.

Recently, at the 30th Annual ARC Industry Leadership Forum in Orlando, I had the privilege of leading a keynote discussion entitled The New Fabric of Demand: Modernizing Collaboration and Transparency for Real-Time Production. As part of that, I moderated an excellent conversation that included Global Commodity Executive Greg Davidson of Rolls-Royce, CEO Berardino Baratta of MxD, and CRO Jamie Goettler of BTX Precision.

In this four-part series, we will explore that conversation fully, digging into how the “fabric of market demand” has fundamentally changed, and why structural modernization, both human and technological, is no longer just an option. It is an industrial imperative that will increasingly determine who wins in disrupted markets.

Why Legacy Workflow Will Actually Get Modernized

If we examine the present through the lens of the past, the fundamental laws of supply and demand haven’t really changed. What has changed is the hyperconnectivity of the world and our compressed time to both reward and volatility.

The hard truth is that legacy linear workflows simply do not work in hyperconnected, digitally-driven environments, which are non-linear by nature. As our industrial environments become more digital, they naturally open up countless new ways for how things can get done and how risk can enter the organization. As a result, disruption has shifted from a rare event to a fairly continuous and pervasive reality. In this new reality, responsiveness differentiates you from the competition, and lag time kills.

To survive and thrive in non-linear environments, tighter, integrated ecosystems are required, where silos are actively torn down or redesigned so that barriers to value can be continuously identified and quickly eliminated. At the core, this concept is unfolding around data access, contextualization, and sharing. It provides the urgency behind the need for building industrial data fabrics.

This rewiring certainly extends beyond operations and enterprise processes, enabling the entirety of the supply chain to be judged on its collective responsiveness to the market, all the way down to the individual company level. In this scenario, data can quickly point out laggards who limit value. As the orchestrators of these supply chains identify these limitations on value, they quickly break off and discard the connection and move on without these weak links.

Pillars of the New Fabric of Demand

To achieve necessary level of operational and supply chain responsiveness, the roles of every entity within an ecosystem must be rethought. In the subsequent three blogs of this series, we will take a deep dive into the three distinct pillars that make up this modern architecture, but I’ll begin by laying them out here:

The Market Signal is the catalyst of the entire ecosystem. It dictates the “what” and the “when,” defining what value, success and risk look like in real-time. In blog 2, I’ll explore how to move from reactive assumptions to proactively capturing the market signals that actually matter.
The Demand Architect is moving beyond traditional order-taking. The Demand Architect designs and orchestrates the ecosystem, aligning external partners as true extensions of the enterprise. In blog 3, I’ll discuss the structural agility required to lead this response, rather than just manage a process.
The Agile Partner is the engine of execution. The Agile Partner links supply chain dynamics directly to the shop floor, differentiating themselves through their responsiveness to the market signal. In the final blog in the series, I’ll tackle how data transparency and trust become technical requirements, not just buzzwords, without exposing mission-critical IP.

Building the Modern Industrial Enterprise

Legacy workflows cannot survive in a non-linear world. Industrial organizations must re-architect operations and ecosystems for real-time responsiveness and secure, transparent collaboration. To do so, they will need to:

Improve the measurement of responsiveness: Efficiency and margin-squeezing are important, but they aren’t game-changers. Your competitive edge now relies on how quickly you can adapt to market signals.
Embrace transparency over secrecy: Modern collaboration requires providing a contextualized “lens” into production status without compromising proprietary IP or cybersecurity. Industrial data fabrics are key.
As always, view technology as a tool, not an outcome: Industrial data fabrics are needed to break silos and AI to manage complexity and improve accuracy and speed of decisions. However, the age-old adage remains true. Just because you can apply AI to something doesn’t mean you should. It must be grounded in measurable Value on Investment (VOI), not just return.

The New Fabric of Demand Blog Series

This is the first in a series of four on The New Fabric of Demand: Modernizing Collaboration and Transparency for Real-Time Production. Over the coming days, I’ll publish a perspective from each of the three pillars of the new fabric of demand:

Pillar 1: The Market Signal
Pillar 2: The Demand Architect
Pillar 3: The Agile Partner
