Our key takeaways from Esri IMGIS International 2026

Last week, we attended the 2026 Esri International IMGIS conference in Frankfurt and joined GIS leaders, telecom operators, and industry partners, all facing the same shift in how networks are managed. The conference gave teams a chance to compare notes. What is working, what is not, and where things are breaking down between planning, field work, and operations. One thing stood out in every conversation. Now more than ever, GIS data needs to actively support the full network lifecycle. It can’t just sit idly in a system of record.

What migrating to the Telecom Domain Network actually involves

The Telecom Domain Network (TDN) introduces a new way to model telecom infrastructure within the ArcGIS Utility Network. As organizations begin planning for adoption, a common question comes up: what does it actually take to move existing network data into this new framework?

While much of the conversation focuses on the structure of the TDN itself, the reality is that migration is less about the model and more about how existing data is translated, adapted, and rebuilt within it.

Trace capabilities for the Telecom Domain Network in 3-GIS | Web

The Telecom Domain Network (TDN) provides a framework for modeling telecom infrastructure within the ArcGIS Utility Network. As organizations begin working with networks built on this model, an important question is how teams will interact with and analyze the connectivity inside those networks.

One of the most important capabilities for telecom analysis is network tracing. Tracing allows teams to follow connectivity across cables, splice points, and equipment to understand how infrastructure is linked and how services move through the network.

Our top takeaways from Esri IMGIS 2025

The Esri Infrastructure Management & GIS Conference (IMGIS) brought together telecom, utility, and infrastructure professionals looking to build smarter, more connected networks.

For 3-GIS, this year marked a milestone. With the addition of our full utility product line, both telecom and utility teams came together under one roof for the first time. That shared presence reflected what’s happening across the industry as fiber and utility networks converge, facing the same challenges in data accuracy, field coordination, and system integration.

What is Esri’s Telecom Domain Network (TDN)?

When Esri introduced the Telecom Domain Network (TDN), it marked an important step forward for modeling communication networks within the ArcGIS Utility Network (commonly referred to as the UN). At the same time, it also raises new questions about how the TDN relates to existing fiber asset management systems, including 3-GIS | Web.

3-GIS has long worked within the Esri ecosystem to help telecom providers get the most from GIS technology. With the TDN emerging, we’re helping lead the conversation on what it means for the future of network management.
