First deep dive into Esri’s Telecom Domain Network – Rotterdam, April 8–10

Last month, I had the opportunity to attend Esri's Telecom Domain Network (TDN) Knowledge Transfer session in Rotterdam. While others from the 3-GIS team have attended two separate Knowledge Transfer sessions in Redlands, CA in 2025, this was my first exposure to the model at a deep technical level, working directly with the Esri team and other partners who are actively engaging in its evolution.

What’s new in the Lio 1 release of 3-GIS | Web

The latest telecom release of 3-GIS | Web, Lio 1, is here, bringing updates across the interface, equipment modeling, and day-to-day workflows.

From a redesigned interface to expanded equipment modeling and workflow improvements, Lio 1 focuses on making tasks simpler and more consistent across the network.

Here are a few highlights.

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.

Telecom industry pulse: March 2026 recap

Network news roundup

March’s telecom news cycle centered on rural fiber expansion, tribal connectivity, consolidation among major providers, and continued pressure to remove policy and permitting bottlenecks.

Providers pushed fiber into smaller and harder-to-reach markets, closed out state-supported projects, and continued pairing infrastructure investment with in-home performance improvements. At the same time, policy conversations focused on clearing legacy barriers slowing deployment.
