Most of us use the Internet every day without giving much thought to how it actually functions behind the scenes. However, with growing debates about network costs, OTT content delivery, and the future of connectivity, understanding the structure of the Internet has never been more important. In our new video, The Internet Story, we explain the core components that make the Internet work, including: How Internet Service Providers (ISPs) connect users and businesses to the global network The importance of Transit Networks and how smaller ISPs rely on larger ones The concept of Peering—both public and private—and why it is usually settlement-free How Content Delivery Networks (CDNs) improve performance and efficiency The rise of Multi-access Edge Computing (MEC) and how it is reshaping real-time data processing We also explore real-world case studies such as: The 2016 Netflix and Swisscom peering dispute, often referred to as "NetflixGate" The more recent regulatory case involv...

At MWC 2025, NTT Docomo highlighted its latest initiatives under the NTT Group's "NTT C89" space-business strategy, such as mobile-connectivity services using unmanned vehicles, or high-altitude platform stations (HAPS), that fly in the stratosphere for days or months, using relays to provide mobile connectivity in mountainous and remote areas, including at sea and in the sky. A presentation on NTT C89 Aerospace Business Strategy is available here while a presentation on NTT DOCOMO's Non-Terrestrial Network (NTN) for Extreme Coverage Extension is available here . Stratospheric connectivity, enabled by High Altitude Platform Stations (HAPS), is emerging as a key solution for extending mobile coverage to remote and underserved areas. However, ensuring that these airborne platforms can provide stable, high-quality connectivity requires extensive testing and refinement. At MWC 2025, NTT Docomo showcased its progress in this domain, highlighting multiple real-world trials...
