Why do we have only 10% of Telcos with 5G SA? (Because it is hard) 5G Standalone promised a new value chain. Yet by mid-2025, only 10% of live 5G networks are SA. The rest rely on Non-Standalone overlays, where over 90% of connections still sit. Why? Because SA is not a software upgrade. It is a structural transformation. Operators face integration with legacy OSS/BSS stacks, migration of voice to VoNR, and stitching together multi-vendor cores in a fragmented supply chain. On 5G SA, the main challenge is not just mid-band deployment. You need nationwide, ubiquitous voice coverage, and mid-bands alone can’t deliver that. To make SA viable, operators must obtain and modernize 700 MHz (and similar low-band) spectrum to secure wide-area VoNR and indoor reach. Without this foundation, SA struggles to move beyond pilots, no matter how much mid-band capacity is in place. Device readiness adds another layer: in 2024, only about 40% of smartphones shipped supported SA out of the box, slowing mass adoption. Then comes the CFO. Between 2015 and 2024, operators burned through $1.6 trillion on spectrum and RAN, with little revenue uplift. Asking for another multi-billion-dollar push into SA, with an uncertain timeline to monetize slicing or URLLC, is a battle. Many boards see it as a cost without immediate ROI. SA is not failing because telcos don’t understand its value. They know it is the only path to industrial automation, cloud-based infrastructure, and differentiated enterprise contracts. It is failing because it collides with the hardest problems in telecom: system integration, spectrum access, device ecosystems, and investor patience. The tortoise is moving, but the gap between hype and delivery grows. The question is whether the race will be won in time to salvage the 5G business case. I dive deeper into these constraints here: https://lnkd.in/g9pP-8rz

On 13 Nov, the Cybersecurity and Infrastructure Security Agency & the Federal Bureau of Investigation (FBI) released a statement (https://lnkd.in/ezrFy_4j) on the US government's investigation into PRC targeting of telco infrastructure: “PRC-affiliated actors have compromised networks at multiple telecommunications companies to enable the theft of customer call records data, the compromise of private communications of a limited number of individuals who are primarily involved in government or political activity, and the copying of certain information that was subject to U.S. law enforcement requests pursuant to court orders. We expect our understanding of these compromises to grow as the investigation continues." With the investigation ongoing, folks should take basic steps now to protect their personal communications. With gratitude to CISA's Senior Technical Advisor Bob Lord (https://lnkd.in/e-WxWiFF) consider the below steps: - Enable FIDO authentication or FIDO https://lnkd.in/ezzyha7t for email & social media accounts - Migrate off SMS MFA for all other logins. Migrate to FIDO/passkeys if you can, otherwise to an authenticator app - Use a password manager for all passwords. Use a strong pass phrase (https://lnkd.in/ebPpTAU5) for the vault password. - Set a telco PIN to reduce chances of a SIM-swap attack - Update the OS and all apps and turn on auto update Additional tips: 1. Encrypt all text and voice communications (some options): - Signal works well on iPhones & Android phones. - iMessage is great if all your contacts are within the Apple ecosystem, though that’s limiting - Collaboration suites like Google Workspace or Teams can work but don’t always encrypt as you might assume. For example, Teams encrypts data point-to-point, meaning it’s decrypted on Microsoft’s servers before re-encrypting it to the recipient. If you want end-to-end encryption, there’s an option, but it’s off by default and only supports two people on the call. - WhatsApp might be ok for some people based on their threat model but understand metadata it keeps (https://lnkd.in/eQkP-Ety) & how it's used (https://lnkd.in/eiZmxgi4). 2. If you use an iPhone disable these carrier-provided services that increase the attack surface: - Disable: Settings > Apps > Messages > Send as Text Message - Disable: Settings > Apps > Messages > RCS Messaging > RCS Messaging 3. Protect DNS lookups (some options): - Apple iCloud Private Relay - Cloudflare’s 1.1.1.1 resolver - Quad9’s 9.9.9.9 resolver 4. Use recent hardware: Apple (13 or newer) or Google (Pixel 6 or newer) 5. Depending on your threat model, consider enabling Lockdown Mode on iPhones: It will disable some features, but it’s manageable

Satellites generate more data in an hour than we can download in a day. Here's why that's about to change. Modern satellites collect an overwhelming amount of information - far more than we can transmit back to Earth quickly. But this isn't just a technical problem. It's potentially costing lives. Here's what's happening right now: When wildfires threaten homes: ↳ Satellite images showing their spread sit trapped for hours During hurricane season: ↳ Vital storm trajectory data reaches emergency teams late - when every minute counts Military operations rely on several-hour-old satellite intelligence ↳ In situations where seconds matter Think about that: We have the data to: • Protect lives • Mitigate disasters • Optimize operations But much of it's stuck in space, waiting to be downloaded. This is why AI-powered satellites are transforming space operations. Take the European Space Agency's new Φsat-2 satellite. Instead of blindly collecting and slowly transmitting back to Earth, it: • Processes images in orbit • Identifies what's actually important • Only sends down actionable intelligence The early indications are game-changing: • 80% reduction in transmission needs • Real-time disaster monitoring • Faster threat detection • Rapid weather pattern analysis Of course, AI in space faces challenges: → Cybersecurity risks → Regulatory constraints → Complex international coordination But the potential rewards are immense for those focusing on: • Reducing data transmission bottlenecks • Providing real-time, actionable insights • Solving critical infrastructure and monitoring challenges This goes beyond a “tech upgrade”. It's a powerful transformation in how we protect communities, save lives, and understand our planet. The old approach: Collect everything, transmit slowly, analyze later. The emerging reality: Think in orbit, send what matters, act immediately. Earth’s early warning systems are getting smarter.

Mario Draghi's analysis of the future of European competitiveness highlights the changes that I have long considered necessary and urgent. Draghi points out that the telecom sector is overcrowded: "Today, the EU has dozens of telecom players serving around 450 million consumers, compared with a handful in the US and China, respectively," and adds, "as a result, in Europe both revenues per subscriber and capital expenditure per capita (...) are less than half the US’ and Japan’s levels," reaching the conclusion that "the declining profitability of the telecom sector now may represent a risk for industrial companies in Europe." There couldn’t be a more authoritative confirmation of the perfect storm I also described on stage at the GSMA Mobile World Congress in Barcelona in 2023 (https://lnkd.in/dfi5yQss). That’s where I showed how it was necessary and urgent to change the rules of the game, because #InactionIsNotAnOption. Some may have thought I was being provocative, but step by step, we are all converging on the same positions. First, there was the report "Much More than a Market" by Enrico Letta and Jacques Delors Institute, then the White Paper by the European Commission with Thierry Breton "How to master Europe’s digital infrastructure needs?". Now, Mario Draghi's perspective joins them, recommending to "reform the EU’s regulation and competition stance to complete the digital single market for telecommunications, harmonizing rules and favoring cross-border mergers and operations," and he adds in more detail: • "reduce country-level ex ante regulation and favor rather ex post competition enforcement • facilitate cross-border integration and the creation of EU-wide players • introduce a ‘same rules for same services’ principle across the EU • encourage the definition of commercial contractual agreements for terminating data traffic and infrastructure cost-sharing • incentivize the deployment of new infrastructures by defining cut-off dates for older technologies". Well, let’s continue down this path, united as we are already doing, thanks to the work of organizations such as the Confindustria team led by Emanuele Orsini, GSMA, and Connect Europe, with the indispensable contribution of the Ministero delle Imprese e del Made in Italy by Adolfo Urso, Alessio Butti, Agcom, and AGCM. We are ready to do our part, aware that the game we are playing is one of the most important: without #TLC, there is no digitalization.

A full-circle moment, 22 years in the making. Back in the summer of 2003, while considering a move to the UK for my PhD, I stumbled upon a visionary article in Science by Professor Philip Russell. It introduced a radical concept: optical fibres that could guide light through air. Among its bold predictions was the idea that such fibres might one day be used in optical communications. I remember thinking, “Wouldn’t it be amazing to work on something so potentially groundbreaking?” At the time, the technology was far from meeting telecom requirements—more dream than reality. But it was compelling enough to spark a journey. Fast forward two decades, through countless prototypes, setbacks, and breakthroughs. Today, I am proud to share that our latest work—published in Nature Photonics—marks a major milestone. In collaboration between Microsoft Azure Fiber and the Optoelectronics Research Centre at the University of Southampton, we have demonstrated an optical fibre with the best combination of loss and bandwidth ever achieved. Arguably, the best optical fibre ever made—and yes, it has an air core! For all of those who dedicate their careers to a vision, moments like this are priceless. A heartfelt thank you to everyone who contributed—whether in small or big ways—to this achievement. And to the next generation: don’t be afraid to chase bold ideas. Sometimes, dreams do come true—and when they do, they can be truly ground-breaking. 👉https://lnkd.in/epqdgWam #Photonics #OpticalFiber #AirGuidingFiber #HCF #HollowCoreFiber #TelecomInnovation #ScientificBreakthrough #MicrosoftAzureFiber #OptoelectronicsResearchCentre #UniversityOfSouthampton #VisionDrivenResearch #FollowYourDreams #EngineeringExcellence
