Natural-language deployment of cellular networks

Fri, 05 Jun 2026 09:00:00 -0500

The 5th Colombia OpenInfra User Group event took place on 5 June 2026 at Pontificia Universidad Javeriana in Bogotá, and I gave a talk there.

Talk (Spanish): Despliegue automatizado de redes celulares usando lenguaje natural
Topic: turning plain-language instructions into 4G and 5G network deployments with LLMs and the ngntelco CLI.

The recording is on the Colombia OpenInfra User Group channel:

From Chaos to Control: managing apps on private cellular networks

Thu, 26 Mar 2026 09:00:00 -0500

I spoke at KubeCon + CloudNativeCon Europe 2026 in Amsterdam.

Talk: From Chaos to Control: A Prescription for Managing Apps on Private Cellular Networks
When: Thursday, 26 March 2026, 11:00 to 11:30 CET
Where: Hall 7, Room C
Track: Emerging + Advanced, intermediate level

What the talk is about

Private cellular networks are where cloud-native software meets physics. The talk covers managing that application complexity: tuning latency through antenna and transmission settings while working within regulatory requirements, and what those lessons from telecommunications engineering mean for Kubernetes deployments in general.

It shows how cloud-native tooling (Helm, FluxCD and Kubernetes operators) tames the operational complexity of running 4G and 5G network functions on commodity clusters.

FluxCD to reconcile cellular network applications

Thu, 11 Sep 2025 09:00:00 -0500

I was a guest speaker at La Hora de Kubernetes, an online community meetup in Spanish, on 11 September 2025.

Talk: Beneficios de usar FluxCD para reconciliar aplicaciones de redes celulares en Kubernetes
Idea: practical GitOps. FluxCD’s continuous reconciliation keeps Open5GS and OpenAirInterface gNB workloads converging to their desired state without manual intervention.

KCD Colombia 2025: cloud-native capabilities for private cellular networks

Fri, 29 Aug 2025 09:00:00 -0500

KCD 2025 was the first gathering of its kind in Colombia: KCD, OSPO-TODO and the Colombia OpenInfra User Group joined in one event on 29 August 2025 at Pontificia Universidad Javeriana in Bogotá (Auditorio Alfonso Quintana, hybrid, free admission). I helped organize it and spoke.

Talk: Enhancing Stability and Enabling Cloud-Native Capabilities for Private Cellular Networks
Idea: bring cloud-native resilience patterns (health probes, rolling upgrades and GitOps reconciliation) to private 4G and 5G running as containerized workloads on Kubernetes.

How I passed the 5 CNCF certifications to become a Kubestronaut

Thu, 10 Jul 2025 09:00:00 -0500

I received the Kubestronaut title, and I wrote up how it went on Medium.

It started with a real project: migrating a telecom private cellular network from Docker Compose to Helm on Kubernetes without a complete Kubernetes background. The cluster did not behave as expected and I did not know which resources to create or how to structure a Helm chart. I turned that into a learning mission, and the certifications gave me a clear mental map of Kubernetes.

A few of the 20 recommendations from the article:

Do not follow anyone’s study method blindly. Each person learns differently.
Master the Linux command line. It saves time in the exam.
Use the Kubernetes documentation and CLI help. Many questions are inspired by them.
Build your own labs and use mock exams, and work on real projects alongside the study.
Failing once or twice is fine. Reflect, study and retake it.
Teach what you have learned, because it reinforces your knowledge.

Read the full article on Medium. You can verify the credentials on Credly and in the CNCF Kubestronaut directory.

C-RAN Emulation Methodologies (IEEE SPAWC 2019)

Tue, 02 Jul 2019 09:00:00 -0500

Paper presented at SPAWC 2019, the 20th IEEE International Workshop on Signal Processing Advances in Wireless Communications, Cannes, France (2 to 5 July 2019).

Authors: Luis Felipe Ariza Vesga, Raymond Knopp, Sebastian Eslava Garzon
Platform: OpenAirInterface, developed at EURECOM

The work presents real-time emulation techniques for testing Centralized Radio Access Network (C-RAN) components using frequency-domain processing on general-purpose processors. From the abstract: the proposal exhibits an improvement of one order of magnitude on generic x86 computers in the average computation time of the multipath channel, compared to the existing time-domain approach in downlink and uplink transmissions.
