Did you know that all members of the WASP community can access the WARA Ops portal free of charge? The platform is continuously expanding, with new features and datasets coming up for 2026.The portal provides access to real‑world operational data contributed by partners, along with CPU and GPU compute resources in a collaborative Jupyter environment. It includes commonly used data‑science packages, support for installing additional tools, a selection of Large Language Models (LLMs), and ready‑to‑use Jupyter notebooks to help researchers get started quickly. To use the portal, simply add a contact person who can vouch for your access.

New network simulator: CitySim

This spring, WARA Ops hosted a partner kick‑off focused on strengthening the platform’s data foundation. Partners presented their planned contributions for the coming years, including one of the most exciting upcoming additions: CitySim, a network simulator that models the dynamics of a real region or city by simulating how people and connected devices move, interact, and generate traffic.

At the event, Fredrik Rönn, project manager at Tieto introduced CitySim, which is planned for integration into the portal during 2026. The simulator enables researchers to run online experiments before moving to a live test network. By synthesizing traffic from user‑behaviour models, CitySim creates realistic scenarios that mirror the complexity of real‑world connectivity.

Tieto is currently exploring how CitySim will be integrated into the portal and what technical constraints need to be addressed to ensure a smooth user experience. Once implemented, the simulator will allow researchers and students to run experiments on datasets generated from the simulated infrastructure, opening new possibilities for studying network performance, user behaviour, and system‑level interactions.

“CitySim will make it possible to extract KPIs and logs from the simulated network. In its first phase, the tool will come with a predefined model, but we at Tieto have developed a web interface that will eventually allow users to create their own models directly within the WARA Ops environment,” says Fredrik Rönn.

In addition to CitySim, Tieto is also contributing datasets from the ARMC3 project, further enriching the data resources available through the portal.

Other news in the portal

Several partners also shared updates on their upcoming contributions during the kick‑off:

• Ericsson (Aitor Hernandez) presented the collaboration between KINET (Kista Innovation Network) and WARA Ops, highlighting past focus areas and future capabilities such as positioning, sensing, and 6G technologies within the testbed.
• European Spallation Source, ESS (Karin Rathsman) showcased past and ongoing student projects that will form their initial data contributions. Their MSc project with Computer Science at Lund University explores how partners, particularly ESS, can share data.
• Saab Kockums (Mikael Lindberg) outlined their plans for 2026, focusing on anomaly‑detection‑based system monitoring, log analysis for distributed mission‑control systems, and predictive maintenance of network infrastructure in high wear‑and‑tear environments.
• Digital Futures at KTH (Frank Jiang) introduced the Stockholm Digital Sandbox, which will use the WARA Ops platform for compute and storage of data from real‑world testbeds across Stockholm City.
