Culture Eats Networks for Breakfast sebastianbarros.substack.com Jan. 6, 2026, 7:55 a.m.
Mature assets, strong incumbents, high technical competence, and slow decision cycles. In that environment, advantage no longer comes from owning better infrastructure. It comes from how effectively the organization coordinates what it already owns. Analysts consistently find that, after asset normalization, operating model and decision velocity account for roughly 30-40% of performance variance. Network quality explains survival but does not explain outperformance. Once technical parity is reached, internal friction becomes the dominant tax. Culture here is not about kindness or slogans. It concerns incentives, permissions, ways of working, and coherence.
Telecom Built the World’s Best Weather Network: with $1T Locked Inside sebastianbarros.substack.com Jan. 4, 2026, 10:05 a.m.
The idea that telecom networks can be used for weather sensing is not new. GNSS-based atmospheric estimation, rain attenuation on microwave links, and radio refractivity effects have been studied for more than 20 years. The physics is well understood and already embedded in network planning and synchronization systems.
Starlink to lower satellite orbits in 2026 amid space congestion interestingengineering.com Jan. 2, 2026, 11:42 a.m.
Starlink’s decision also comes after the company disclosed in December that one of its satellites suffered an in-orbit anomaly, producing a “small” amount of debris and cutting off communications with the spacecraft at an altitude of about 260 miles. The company said the satellite, one of nearly 10,000 currently in orbit for its broadband internet network, rapidly lost 2.49 miles in altitude, suggesting an internal explosion, in what was described as a rare kinetic accident.
Les États-Unis veulent obliger les touristes à dévoiler leurs activités sur les réseaux sociaux www.lefigaro.fr Dec. 11, 2025, 10:53 a.m.
La proposition a pris corps mercredi avec la publication d’un avis au Federal Register, le Journal officiel américain : l’administration Trump veut désormais exiger des visiteurs bénéficiant du programme d’exemption de visa (ESTA) qu’ils fournissent l’historique de leurs comptes sur les réseaux sociaux sur cinq ans.
5G Was the Last Mobile Network Built for Humans sebastianbarros.substack.com Dec. 6, 2025, 4:31 p.m.
The next decade forces telecom to abandon human centric assumptions and design a network that can support continuous inference, real time robotics and machine generated traffic at global scale.
The Telco Organizational Black Hole sebastianbarros.substack.com Dec. 4, 2025, 10 a.m.
Why Telcos Are Spending Billions on Transformation, Only to Feed the Ghost of Yesterday... The industry is not just underperforming; it is actively using its massive capital expenditure to service the maintenance and complexity of its own past, leading to a permanent state of diminishing returns. The key challenge we are facing is that the problem is not the telco’s technology stack; it is the telco’s DNA.
A Sneak Peek at India’s Planetary Size Telecom Industry sebastianbarros.substack.com Nov. 20, 2025, 1:11 p.m.
India’s telecom market behaves like a digital continent. It carries volumes that rival entire regions, yet it runs on the lowest revenue per user among major economies. Two operators deliver world-class network performance at a national scale, one operator remains structurally distressed, and a state player anchors policy goals. This mix of extreme usage, thin margins, and relentless investment pressure creates a system that is both remarkable and unstable.
Confessions: 15 Brutal Truths in Telco sebastianbarros.substack.com Nov. 18, 2025, 4:26 p.m.
Every week, I collect private confessions from telco CXOs. This time, I pulled together fifteen short stories. Small moments that expose the truths our industry keeps quiet. Real voices. Real pressure. Real mistakes. Real opportunities. A clearer picture of telco emerges one confession at a time. A collection of honest reflections from the people who actually run networks and see the industry from the inside every day. 
WiFi and Cellular Are Not Friends sebastianbarros.substack.com Nov. 16, 2025, 7:05 p.m.
The reason these collisions keep appearing is that WiFi and cellular no longer occupy separate roles. They chase the same physics, the same mid-band capacity, the same enterprise environments, and the same edge compute opportunities. The Brussels decision is only the most recent signal that the two stacks are converging on the same territory, and every time that happens, the tension becomes visible.
Best Satellite Internet for RVs ubifi.net Nov. 5, 2025, 8:23 p.m.
Many avid travelers, campers, and RVers settle on satellite Internet as a solution to the losses in connectivity they experience while traveling through rural and highly remote areas of the United States. However, depending on your needs, satellite Internet plans can be too pricey to be practical. Furthermore, satellite Internet often comes with problems such as high latency and data caps. Before you search for “satellite internet providers near me” again, consider switching to renowned rural 5G/4G LTE Internet provider UbiFi.
Telcos, Hardware Is Sexy Again  sebastianbarros.substack.com Nov. 3, 2025, 8:59 a.m.
For more than a decade, the telecom industry has been busy trying to reinvent itself as something it is not. “Techco,” “Servco,” “Digital Operator”, all elegant slogans for an age that believed value came from software and platforms. Telcos sold towers, outsourced data centers, and trimmed engineering ranks to chase cloud partnerships and brand adjacency. It looked modern; it was strategically backward. While telcos were distancing themselves from hardware, the world quietly re-industrialized. AI transformed computing from a software abstraction into a physical process, a factory operation that consumes electricity, produces tokens, and generates cognition. The bottleneck is no longer spectrum or subscriber growth but the energy-to-intelligence ratio: how many joules it takes to deliver a decision. Every major technology company is now an energy company in disguise. Global CapEx tells the story.
How to Get Our Telco Mojo Back (We’re Doing It All Wrong) sebastianbarros.substack.com Oct. 29, 2025, 11:37 a.m.
Telco used to be the most exciting place on Earth. We were the people who made the impossible happen. We connected continents, carried the first digital signals, and built mobile networks that turned communication into a human right. We were the engineers who bent physics to our will. Then something happened. We turned into administrators of connectivity. The industry that invented the digital age now spends more time in regulatory filings than in labs.
WoW: Nvidia Buys Into Nokia  sebastianbarros.substack.com Oct. 28, 2025, 5:09 p.m.
When Nvidia takes a billion-dollar stake in an old-guard telecom vendor, it’s not a financial gesture but a signal. A signal that the AI arms race is moving from datacenters into the network fabric itself. On October 28, 2025, Nokia announced that Nvidia will invest $1 billion in newly issued shares, acquiring roughly 166 million shares, or about 3.5% of the company, and forming a deep strategic alliance to co-develop 6G and AI-native networking technologies. Nokia’s stock jumped 18 % within hours.
Everyone Talks About AI. Few Understand What It Means for Telcos. sebastianbarros.substack.com Oct. 23, 2025, 4:05 p.m.
Most telcos still haven’t come to terms with what AI truly means for their future. This is a 2007 iPhone moment on steroids, not another radio upgrade, not a “TechCo” rebrand, and certainly not a digital transformation checklist. AI is changing the very physics of how humans, and now machines, connect and interact across the digital and physical world.
The Telco identity crisis sebastianbarros.substack.com Oct. 20, 2025, 3:12 p.m.
Before 2007, Telcos knew precisely who they were.They built networks. They connected nations. They carried the weight of communication with pride. Telcos were infrastructure institutions: disciplined, engineered, predictable. Then, in 2007, everything changed. The iPhone turned connectivity into an afterthought. The network disappeared behind the screen, and the center of gravity shifted from infrastructure to experience. For the first time, the telco wasn’t the main act; it was the invisible stagehand behind the digital revolution.
Confessions of a Telco Executive: What Vendors Know (and We Deny) sebastianbarros.substack.com Oct. 13, 2025, 12:56 p.m.
This week, the confession comes from the other side of the table. From the people who have built our systems, sat through our meetings, and quietly watched the same story repeat across continents: the vendors.They have seen how decisions are made, how timelines are invented, and how politics replaces logic. They know when a project will fail before the first contract is signed. They understand that most telcos no longer innovate; they negotiate. Procurement has replaced product. Compliance has replaced creativity.
The Evolution of the Telco CEO: 2000–2025 sebastianbarros.substack.com Oct. 8, 2025, 3:30 p.m.
Telco CEOs have changed as much as the networks they run. Two decades ago, most were engineers obsessed with coverage maps; today, they’re diplomats managing politics, investors, and cloud partners.
Telco Culture is diverging: Traditionalists vs. Technologists sebastianbarros.substack.com Aug. 27, 2025, 11:54 a.m.
Post-COVID, telcos share a baseline of compliance, security, and sustainability, but now split between traditionalist office-first cultures and technologist AI-first models.
