omlox - the open locating standard

omlox is the world's first open locating standard which aims to implement flexible real-time locating solutions with elements from various manufacturers without requiring any project planning. The term omlox is derived from the Latin terms "omni" = omnipresent and "locus" = location. omlox is part of Profibus & Profinet International.

omlox enables unified access to location data

With the ability to integrate software such as Manufacturing Executive System (MES), asset tracking, and navigation with anti-collision, along with hardware such as drones, AGVs, and loading trucks within the domain of localization – omlox is setting a new benchmark in Industry 4.0. omlox enables interoperability and flexibility for different trackable providers within single or multiple tracking zones, which is achieved through two core components: omlox hub and omlox core zone.

omlox architecture – an holistic approach for locating systems
Overview omlox structure

The omlox standard as such is comprised of two main elements:



  • omlox hub: A lightweight middleware that provides standardized interfaces to location data and location services – across technologies and vendors.


  • omlox core zone: An open ultra-wideband system, that facilitates a plug-and-play, real-time tracking of hardware from multiple vendors.



Both elements of omlox already provide great value and flexibility while setting up a locating system or using location data for industrial use-cases individually. But the combination is even more powerful – especially in real-time use cases on a shopfloor or in a warehouse.

omlox core zone

For sure ultra-wideband (UWB) is the rising star of location technologies, being integrated in smartphones, laptops and cars these days. UWB is a radio-technology that uses short impulses on a broad frequency band. This approach is very robust when it comes to reflections on metallic surfaces and allows for a very fast and precise computation of location. But in an industrial setup UWB is even today a very fragmented landscape with small vendors that provide proprietary technologies.

This is about to change with

By specifying the wireless interface, how UWB-enabled devices like tags, tools or AGVs should communicate with an UWB infrastructure, an interoperable setup can be achieved. One omlox core zone can service multiple use cases and can locate hardware from multiple vendors. This allows for a much lower total cost of ownership and a faster return on investment.

omlox hub
omlox hub

An omlox hub is specified as a lightweight locating middleware with very easy to use APIs. It allows for seamless access to location data and services – no matter which location technologies are been used.


Software vendors and integrators do not have to implement custom interfaces for different vendors anymore. Location-technology providers can benefit from wide array of existing software.






An omlox hub is built on very powerful software concepts and functionalities:
Geo-ReferencingAn omlox hub provides location data in local and global coordinates – no matter wether something is inside or outside of a building.
Identity ManagementAn omlox hub provides consistent identy management for moving things – across locating technologies.
Geo-FencingAn omlox hub supports geo-fencing functionality – independent of the locating technology.
Distance computationAn omlox hub can compute distances between moving objects in local and global coordinates.


Track and trace applications

Track and trace applications locate all sorts of assets in various environment - ranging from shopfloor, warehouse to yards or even in-between different sites. The type of assets is very manifold, from products, to tools, humans or means of transportation like AGVs, forklifts, trucks, or ships. Main benefits of those track and trace applications are
the reduction of manual search times, more efficient asset usage, an up-to-date inventory, and less CAPEX.

Location-based automation

When things change their location, this is often also an indication of a certain step in a large process-chain, e.g., a product is been built in a step-based manner at different production station in a plant. Having access to location-data and been able to use geo-fencing and proximity events, can facilitate a location-based automation, for example by presenting the relevant information to a worker at a given station or by automatically generating shipment list, based on the goods on a truck.

Operation and maintenance

Maintaining and operating mobile assets can be a challenging task, especially when they are used in dynamic indoor environments or when compliance rules need to be applied. Having the flexibility of omlox to locate mobile assets precise via UWB or any other locating technology and using the some locating technology to give maintenance staff an orientation in unknown locations, can streamline the complete process. This especially true when applying modern user-interface technologies like AR, where workers can navigate and find things hands free.

Automized, optimized and sustainable material flow

In today’s production and intralogistics more and more autonomous robots are being deployed – stationary and mobile ones. It becomes a challenge to orchestrate the movements of all the mobile elements in a streamlined and safe manner. Omlox enables a holistic overview of the position and movements of all things in those environments and allows for an optimized material flow, beyond considering only one means of transportation or on asset type. In addition, this allows also to optimize the material flow considering energy consumption and carbon-footprint.
