Tutorial Session on Current Trends and Key Challenges of Satellite communications

The 2024 Global Forum on Connecting the World from the Skies, held on November 25-26, brought together policymakers, industry leaders, and technical experts to discuss the evolving landscape of Non-Terrestrial Networks (NTNs). Hosted by the International Telecommunication Union (ITU) and Saudi Arabia’s Communications, Space & Technology Commission (CST), the event highlighted NTNs' critical role in shaping the future of global connectivity.

The conference featured a rich lineup of keynote speeches, panel discussions, tutorial sessions, and an award ceremony. One standout session on Day 1 was the tutorial "Satellite Communications: Current Trends and Key Challenges," delivered by Professor Riccardo De Gaudenzi of the University of Parma.

This session explored the vital role satellite networks play in global communication, from video broadcasting to bridging connectivity gaps in underserved regions. Traditionally focused on broadcasting and professional applications, satellite networks are now increasingly essential for broadband and mobile services.

The video below reviews the evolution of satellite systems, key market drivers, frequency bands, system architectures, and emerging technologies. It covers innovations in:

  • Non-geostationary narrowband constellations like Iridium and Starlink
  • Geostationary mobile communication systems such as Inmarsat and Thuraya
  • High-throughput satellites, including Viasat and Eutelsat
  • Broadband mega-constellations like OneWeb and Amazon Kuiper

Video Highlights:

  1. Advancements in Satellite Technology: The video showcases innovations in satellite design, launch capabilities, and new technologies improving efficiency and expanding global coverage.
  2. Impact on Global Communications: It emphasizes how these advancements enhance connectivity in remote areas, support disaster response efforts, and drive the growth of the Internet of Things (IoT) and emerging technologies.
  3. Industry Challenges: The session also addresses critical industry hurdles, including regulatory complexities, the need for international collaboration, and technical challenges related to maintaining and upgrading satellite infrastructure.

Note: The presentation slides have not been shared.

This tutorial offers a comprehensive look into the future of satellite communications, providing valuable insights into how NTNs are revolutionizing global connectivity.

Highlights from XGMF's Conference to Advance Millimetre Wave Technology

On April 1, 2024, two of Japan's leading connectivity organizations—the 5G Mobile Promotion Forum (5GMF) and the Beyond 5G Promotion Consortium (B5GPC)—joined forces to create the XG Mobile Promotion Forum ( XGMF ). This merger symbolizes a pivotal step in accelerating the adoption of next-generation wireless technologies. In May 2024, XGMF's Millimeter Wave Promotion Ad Hoc (Millimeter Wave AH) hosted the International Workshop on Millimeter Wave Dissemination for 5G. This event aimed to foster the adoption of millimeter wave (mmWave) technology in Japan and beyond, drawing an audience of approximately 200 attendees and broadcasting in both English and Japanese. The workshop featured opening remarks by Mr. Naohiko Ogiwara, Director of the Radio Department, Telecommunications Infrastructure Bureau, Ministry of Internal Affairs and Communications (MIC). Key speakers included: Mr. Takanori Mashiko (MIC, slides ) Mr. Sam Gielges (Qualcomm, online - no slides) Mr. Christopher Pric...

Testing, Refining, and Improving Stratospheric Connectivity: NTT Docomo’s HAPS Trials

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...

How Do Apple AirTags Work?

Apple AirTags have steadily gained popularity in the smart tag market. A recent report highlighted that 69% of smart tag buyers in late 2024 chose an Apple AirTag. This marks a significant rise from 45% in early 2022. In contrast, Tile, the category pioneer now owned by Life360, has seen its market share fall to 11% from 17% during the same period. Samsung's Galaxy SmartTags now hold second place. Interestingly, the technology behind AirTags resembles concepts like Opportunity Driven Multiple Access (ODMA) or Multihop Cellular Networks (MCNs), which I have previously explored . A similar approach has also been discussed regarding Bluetooth-based Ad-Hoc networks . How Do They Work? AirTags primarily use Bluetooth Low Energy (BLE) to communicate with nearby Apple devices that are part of the Find My network. This vast network consists of millions of Apple devices, including iPhones, iPads, and Macs, which can detect AirTags and securely relay their location back to the owner. Addit...
