The best of both worlds: AoA & Mesh technology combined in one day

AoA and Cavea Mesh Working Together: The Optimal Location Solution for Your Applications

Location technologies such as AoA (Angle of Arrival) and Cavea Mesh play a central role in making processes across various industries more efficient, transparent, and digital. Whether in factories, modern warehouses, or hospitals—the question often arises as to which technology is better suited: AoA, with its high precision, or Cavea Mesh, a flexible, scalable, and wireless solution with long battery life. But you don’t have to make that decision. 

With our Tribrid® tag, we combine both technologies into a single system. This means you can use AoA precisely where the highest precision is required while simultaneously benefiting from the cost-effective, low-maintenance, and easily scalable Cavea Mesh technology for the rest of the area. No additional tags, no compromises—simply a seamless tracking solution that adapts perfectly to your applications. 

In this article, we not only compare both technologies on a technical level, but also highlight their practical benefits in industrial applications. Learn how you can efficiently and cost-effectively meet your location tracking needs with the right combination of AoA and Cavea Mesh. 

What is AoA (Angle of Arrival)?

Angle of Arrival (AoA) is a positioning technology that has been specially developed for precise real-time indoor localization. It enables very precise localization of objects or people with an accuracy of less than one metre. This makes AoA particularly suitable for applications where exact position data is required – whether in industrial production, healthcare or logistics.

A key advantage of AoA is its comparatively low latency, which enables movements to be detected almost immediately. However, the technology requires a more complex installation, as antennas need to be strategically positioned and connected to the infrastructure via cables. This makes AoA less flexible in terms of scaling, but extremely reliable for scenarios with high precision requirements.

Technical overview

AoA is based on measuring the angle from which a radio signal arrives at an antenna. This technology uses Bluetooth Low Energy (BLE) and combines the energy efficiency of this standard with advanced signal processing. Several permanently installed antennas receive the signals from BLE tags and calculate the exact position of the object based on the different angles of incidence. By continuously analyzing these signals, movements can be tracked in real time. This enables reliable indoor localization with high precision – a decisive advantage for companies that require seamless traceability of their assets.

What is Cavea Mesh?

Cavea Mesh is a high-performance indoor positioning technology characterized by easy installation, high scalability, and reliable network capabilities. Unlike AoA, which relies on fixed, wired antennas, Cavea Mesh uses battery-powered devices that form their own network and efficiently relay data. This eliminates the need for wiring, which significantly reduces the installation effort and enables quick and flexible commissioning, even during regular operation.

A key advantage of this technology lies in its virtually unlimited scalability: Cavea Mesh can connect hundreds of thousands of devices within a single network. In addition, the network is self-organizing and self-healing—it dynamically adapts to changes in the environment and remains stable even when individual nodes fail. The positioning accuracy is 5–7 meters, which is sufficient for many industrial applications. Compared to AoA, the latency is higher at approximately 30 seconds; however, it offers a very good solution for many processes—such as transactions in warehouse systems—since a delay of a few seconds is usually not critical in these cases. 

Technical overview

Cavea Mesh is based on a decentralized communication principle (mesh), in which each device functions as an independent node. These nodes communicate directly with one another and relay data across the network without the need for a central infrastructure. The result is a robust, energy-efficient system that can be flexibly adapted to various environments.

Thanks to its wireless operation and long-lasting batteries, Cavea Mesh can be used virtually anywhere—from manufacturing facilities to warehouses to hospitals. Businesses benefit from easy integration, rapid deployment, and reliable, wide-area coverage without high infrastructure costs.

Which technology for which application?

The choice of the right positioning technology depends heavily on the specific requirements of the respective application. While some industries rely on maximum precision, others focus on simple scalability and comprehensive coverage.

AoA for high-precision tracking in sensitive environments

AoA is the preferred solution when centimeter-precise positioning is required. Especially in factories or warehouses, where exact positioning of equipment, tools or goods carriers is required, the technology shows its full potential. RTLS systems with AoA make it possible, for example, to track work equipment in real time. AoA can also help to minimize delays and make efficient use of production capacities in the manufacturing industry, where material flows and production processes need to be optimally coordinated.

However, the installation effort is higher, as AoA infrastructures work with permanently installed antennas and cabling. However, companies that value maximum accuracy and are prepared to invest in a stable infrastructure benefit from reliable real-time localization.

Typical use cases for AoA:

• • Tool and material tracking in production environments

• • Security and access control in sensitive areas

• • High-precision positioning for machine control

• • Automation for booking processes of e.g. goods carriers in small areas with high selectivity

Cavea Mesh for Flexible and Scalable Location Solutions

Cavea Mesh technology is ideal for companies that need a simple, scalable, and cost-effective solution for asset tracking. Especially in warehouses, logistics centers, and large industrial facilities, Cavea Mesh offers a robust, wireless infrastructure that can be implemented with minimal installation effort. Thanks to our extremely efficient mesh protocol, millions of objects can be tracked seamlessly — whether it involves tracking pallets, containers, or tools.

Although the positioning accuracy of 5–7 meters is not as high as that of AoA, it is more than sufficient for many applications. Cavea Mesh stands out for its ease of implementation and reliable data transmission, particularly in supply chain operations or industrial facilities where large areas need to be covered efficiently.

Typical use cases for Cavea Mesh:

• • Asset tracking in large warehouse and production halls
    
    

• • Load carrier tracking on company premises and automatic booking to storage locations
    
    

• • Tool and machine localization in industrial facilities
    
    

• • Tracking of production orders and components

• • Comprehensive Inventory Management in Logistics Centers

Which tracking technology is right for you?

There is no one-size-fits-all solution when it comes to location technologies—and with our Tribrid® tag, you don’t have to choose between different technologies. Our solution combines AoA and Cavea Mesh in a single tag, allowing you to make the most of both technologies in your environment.

When is AoA used?

• • When centimeter-level positioning is required in certain areas

• • When critical processes require real-time localization with minimal latency.
    
    

• • When a wired infrastructure can be provided for these specific zones.

When does Mesh technology show its strengths?

• • When a simple, fast, and wireless installation is crucial.

• • If an accuracy of 5 to 7 meters is sufficient

• • When a cost-effective and energy-efficient solution is required.

With our Tribrid® tag, you get the best of both worlds: precision where it’s really needed, and a flexible, scalable tracking solution for everything else. This allows you to optimize your processes without having to choose between two technologies or use duplicate hardware.

But that’s not all—our Tribrid® tag also offers BLE and RFID technology. If only basic identification is needed in certain areas, such as in goods receiving, RFID can be used. This ensures that your tracking solution remains as flexible and cost-effective as possible. In outdoor settings, simple BLE solutions are often the best choice for tracking vehicles or monitoring the route to the customer.
