Supply Chain Visibility: How Real-Time Location Technology Closes the Data Gap

Walk through most warehouses or production facilities, and you'll find the same quiet frustration: someone looking for something that the system says should be there. A pallet that was logged in yesterday. A container that left the supplier two days ago. A piece of equipment that was returned last week.

The records are accurate. The asset is simply somewhere else.

This is the visibility gap, and the scale of it is striking. For organisations that want full visibility into supply chain logistics, it is the predictable result of building operations on systems designed to record decisions rather than track continuous physical movement.

Transactional records vs. physical reality

ERP, WMS, and TMS platforms form the backbone of modern supply chain management. But they share a fundamental design constraint: they update when something is logged, not when something moves.

Between those logged events, materials are staged on production floors longer than expected. Inventory gets repositioned within a warehouse. Containers sit at partner sites well past their scheduled return. Work-in-progress stalls between production steps. Returnable packaging circulates across supplier networks with no reliable way to track where it is or how long it has been sitting idle. None of this generates a system update, and all of it quietly erodes the accuracy of the data that operations teams rely on to make decisions.

The gap between what systems show and what's physically happening is where delays are born, assets disappear, and costs accumulate. Usually invisibly, until the problem is too large to ignore.

Supply chain visibility technology: from limitation to convergence

Achieving full supply chain visibility has never been just a data problem. It has always been a technology problem.

For a long time, the available tools simply weren’t designed to provide continuous, reliable location data across complex environments. RFID, for example, is widely used across supply chains, but because it relies on fixed checkpoints and manual or automated scanning, it only confirms where an asset was last seen, not where it is now. When something moves outside those checkpoints, the system goes dark.

More recently, cellular-based positioning technologies like 5G and future 6G have been positioned as a potential answer, promising seamless indoor-outdoor tracking through a single network. But in practice, these technologies are still evolving. As explored in Is 5G ready or not for industrial asset tracking?, challenges around power consumption, cost, and infrastructure requirements limit their applicability to higher-value assets like vehicles, AGVs, or handheld devices, rather than the thousands of lower-cost assets that typically move through a supply chain. ABI Research also highlights that enterprises continue to face significant barriers in deploying RTLS at scale, with 87% of organizations yet to fully implement such systems.

At the same time, other positioning technologies have matured significantly. Bluetooth Low Energy (BLE), Ultra-Wideband (UWB), and GPS have each evolved to solve specific parts of the visibility problem more effectively.

BLE enables scalable indoor tracking across large facilities with low infrastructure cost and long battery life, making it practical to deploy across thousands of assets. UWB tracking provides consistent centimetre-level accuracy using time-of-flight positioning, even in complex industrial environments where interference would typically degrade performance. And GPS continues to improve as a reliable outdoor layer, with innovations in power efficiency and hybrid positioning expanding its role in asset tracking beyond traditional fleet use cases. (For a deeper look at recent advancements, see 5 innovations in GPS asset tracking.)

What has changed is not just the performance of individual technologies, but the ability to combine them. At a higher level, the omlox Hub standardizes location data across different positioning systems into a unified, technology-agnostic data layer. This makes it possible to use the right technology for each environment (UWB for precision, BLE for scale, GPS for outdoor tracking) while maintaining a single, consistent view of asset location, movement, and events across the entire supply chain.

Together, this convergence of technologies and standardization is what finally makes continuous, end-to-end supply chain visibility feasible—from the production floor to the logistics network and back.

What changes when visibility improves

The shift from reactive supply chain monitoring to real-time visibility changes what operations teams can act on.

The operational case is well documented. McKinsey research on next-generation supply chain operations projects up to 30% lower operational costs, a 75% reduction in lost sales, and inventory reductions of up to 75% for organisations that act on real-time location data. A more recent McKinsey analysis found that one aerospace company that restructured around improved supply chain visibility reduced expedited-service costs by 30 to 50% and achieved a 15 to 20% improvement in inventory turns.

When teams can see where assets actually are, search time drops, bottlenecks surface before they become delays, and asset cycles tighten across the network. Historical movement data compounds that value over time, showing not just where things are, but how they move, where they slow down, and where the process has room to improve.

The shift is from managing based on what was recorded to managing based on what's actually happening.

Where Pozyx fits

Pozyx builds real-time location systems designed specifically for the indoor-outdoor visibility gap. The platform layers UWB, BLE, and GPS into a single unified view, so organisations can track assets continuously regardless of where they are in the supply chain.

Inside a facility, Pozyx delivers manufacturing visibility at the precision that makes location data genuinely useful for operational decision-making. UWB handles environments where exact positioning matters, giving production managers a live view of exactly where a component is on the floor, whether a tool has been returned to the right station, or how long a pallet has been sitting in a staging area. BLE extends that coverage across broader areas where zone-level awareness is sufficient, without requiring the same infrastructure density. Together, they ensure nothing inside a facility goes dark.

Outdoors, GPS takes over. Vehicles and containers moving between sites are tracked continuously, with location data flowing into the same platform that handles indoor positioning. But the capability doesn't stop at the facility gate. Pozyx GPS-enabled devices can also scan for BLE signals from tagged assets, meaning that when a tagged container or pallet is loaded onto a tracked vehicle, the system knows which assets are on which truck and where that truck is at any point in transit. An asset doesn't disappear the moment it leaves the building. It stays visible through the entire journey, from the production floor to delivery and back again.

All of that data surfaces in the Pozyx platform, which gives operations teams a single place to see every tracked asset across their network. Live floor maps show asset positions in real time, while reporting tools let teams dig into movement history, dwell times, and utilisation patterns. Analytics built on top of that data make it straightforward to spot recurring bottlenecks, track asset availability over time, and build the kind of operational picture that informs better planning. Rather than pulling information from multiple disconnected systems, teams get end-to-end supply chain visibility, one view of what's happening, and the tools to act on it.

The platform is built around the omlox Hub, which standardizes location data across technologies and devices into a single, consistent data layer. This makes it possible to apply geofencing, track asset movements, and trigger events in a uniform way, regardless of whether the data comes from UWB, BLE, or GPS. Through its standardized APIs, the omlox Hub enables out-of-the-box connectors to major ERP and WMS systems, including SAP and Oracle, ensuring that real-time location data flows directly into the tools operations teams already rely on.

The bottom line

Most supply chains are managed on a version of reality that's already out of date by the time it reaches a dashboard. That gap is where efficiency leaks, assets disappear, and decisions get made on incomplete information.

Closing it doesn't require replacing existing infrastructure. It requires adding the physical layer that those systems are missing. Organisations that do that stop reacting to problems that have already compounded and start managing operations as they actually unfold.
