Post-Quantum Cryptography in 3GPP
Quantum computing often appears in discussions about 6G, but one area where its impact is already influencing 3GPP work is security.Many of the public-key cryptographic algorithms used today rely on...
View ArticleEnergy Efficiency Improvements in 3GPP Technologies: From LTE to 5G-Advanced
Energy efficiency has become one of the most important topics in mobile networks. Operators need to support growing traffic, wider bandwidths, massive MIMO, better coverage and new services, while also...
View ArticleMulti-Panel UE (MPUE) in 5G and 5G-Advanced
With the introduction of millimetre-wave spectrum in 5G NR, antenna design at the UE became significantly more complicated. At these higher frequencies, increased propagation and penetration losses...
View ArticleNext Generation eCall Finally Moves to 4G and 5G
Back in 2022, I wrote about the transition from the original eCall system to Next Generation eCall, or NG eCall. At the time, one of the big concerns was what would happen to millions of vehicles...
View ArticleWhy Connectivity on Trains Is Still So Poor
Anyone who travels regularly by train will recognise the experience. The phone shows a mobile signal, sometimes even 5G, but webpages refuse to load, video calls freeze and messages remain stuck...
View ArticleFrom 3GPP MPS to Wi-Fi 7 EPCS
Back in January 2011, I wrote about Enhanced Multimedia Priority Service, or eMPS, in 3GPP Release 10. At the time, the focus was on extending priority treatment beyond basic voice calls to packet data...
View ArticleFrom Voice-Centric to Data-Driven Critical Communications
Back in 2024, I came across an excellent GSMA APAC webinar looking at the evolution of critical communications from predominantly voice-centric systems towards broadband, data-driven solutions. I had...
View ArticleRelease 19 Takes Satellite, NTN and Aerial Connectivity Further
3GPP Release 19 continues the evolution of 5G-Advanced and, among many other areas, brings important enhancements for satellite access, Non-Terrestrial Networks (NTN), Uncrewed Aerial Systems (UAS),...
View ArticleMid-Band Spectrum Still Matters for 5G and Beyond
Mid-band spectrum has become one of the most important parts of the mobile network story. Low-band spectrum is essential for wide-area coverage and better indoor reach, while high-band spectrum,...
View ArticleCBRS Comes of Age as a Shared Spectrum Success Story
The Citizens Broadband Radio Service, better known as CBRS, has often been described as an experiment in spectrum sharing. Based on the latest OnGo Alliance webinar on the state of CBRS, that...
View Article7 MHz Brings Much Needed Flexibility to 5G NR
The evolution of channel bandwidths in 5G NR has been relatively conservative compared to earlier generations, but recent developments in 3GPP Release 19 show that this is beginning to change. The...
View Article3GPP Release 19 Description and Summary of Work Items
As the journey towards 3GPP Release 20 and 6G (3GPP Rel-21) continues to gather pace, the recently concluded Release 19 comes with a clearer view of what the next phase of 5G evolution, often referred...

The development of each new mobile generation is not only about new technologies and capabilities. It also requires evolution in the way standards themselves are created, maintained and consumed. As...
View ArticleStrengthening Critical Infrastructure Security with OSINT
Cybersecurity conversations in telecoms often focus on IT systems, cloud platforms and enterprise networks. Yet beyond the data centres and mobile cores lies another domain that is arguably even more...
View ArticleSeven AI Concepts Shaping Network Intelligence
AI has become so deeply embedded in our everyday working lives that it is no longer limited to data science teams or research labs. In telecoms, AI now plays a central role in network planning,...
View ArticleTelecom Security Realities from 2025 and Lessons for 2026
Telecom security rarely stands still. Each year brings new technologies, new attack paths, and new operational realities. Yet 2025 was not defined by dramatic new exploits or spectacular network...
