Emulating real-world network conditions to verify applications & systems
Exploring the unique challenges and critical considerations in testing and optimization.
Non-Terrestrial Networks (NTN), including satellite communications, operate in highly complex environments with unique challenges such as rapid handovers, atmospheric interference, and fluctuating signal quality. These factors introduce significant difficulties in maintaining consistent application performance over long distances and high-latency links. Effective testing and optimisation of NTN and satellite networks require accurate replication of real-world conditions to address these complexities and ensure reliable operation in demanding scenarios.
Use cases
Testing applications and performance over satellite networks
Emulating moving objects in NTN and satellite networks
When working with networks involving fast-moving objects, such as LEO satellite constellations, fixed network parameters simply won’t capture the dynamic nature of these environments.
Calnex Network Emulation enables you to automate dynamic changes in network conditions over time, without the need for programming. This allows for realistic testing by simulating the rapidly changing network conditions experienced in real-world satellite operations.
Test applications over provider satellite network conditions
Validate the Quality of Service (QoS) of your applications by testing them over emulated satellite networks like Starlink, OneWeb, O3B, and Viasat.
With a controllable and repeatable environment, you can ensure consistent performance across multiple providers, mitigating risks before deployment.
Recreating complex NTN topologies for comprehensive testing
Accurate emulation of diverse network topologies is crucial for research and development. By recreating complex NTN environments—including 5G, LEO, MEO, GEO, VSAT, WAN, as well as UAS and HAPS platforms—you can thoroughly test your applications under the precise conditions they will face in real-world scenarios. Understand the interaction between terrestrial and non-terrestrial networks, optimise network performance, and validate the robustness of their solutions across multiple layers of connectivity.
Emulating these topologies allows you to anticipate potential issues, such as latency variations, handoff challenges, and the impact of environmental factors.
Controllable and repeatable satellite conditions on-demand
In the fast-evolving world of Non-Terrestrial Networks (NTN) and satellite communications, ensuring that your applications and services are resilient and ready for deployment is crucial. Calnex Network Emulation enables you to confidently test your solutions under real-world satellite conditions without the prohibitive costs associated with live satellite trials.
Recreate the exact conditions networks will face in orbit—whether it’s the latency challenges of GEO satellites or the dynamic conditions of LEO constellations. By simulating these environments in a controlled and repeatable manner, Calnex enables you to identify potential issues and optimize performance before your systems or applications go live.

Case study: European space agency
A prominent research institute had a requirement for a network emulator as part of a project sponsored by the European Space Agency. The project involved connections between 5G users and data centres or services, and they were looking for a real-time emulator to simulate part of a satellite constellation, specifically up to 10 low-earth orbit (LEO) satellites.
They aimed to control how these satellites communicated, accurately mimicking real LEO constellations, which are usually updated by a geostationary (GEO) master satellite. After searching the market and failing to find a solution that met their needs, they discovered the NE-ONE which allowed them to model the 10 orbital satellites and their interconnections, as well as the links to the ground stations. Moreover, the REST API and JavaScript updating capabilities enabled precise, real-time constellation behaviour changes down to the centi-second.
