Top 5 Posts for 2025

Connectivity Technology Blog may still be a relatively small and focused publication, but its scope is broad. The blog looks across the full spectrum of connectivity technologies, from fixed and mobile cellular networks such as 4G, 5G and 6G, through to Wi-Fi, IoT, Bluetooth, LoRaWAN, Sigfox and satellite communications. Since launching in 2019, the aim has always been to explain how these technologies work and why they matter, without hype or unnecessary complexity.

2025 turned out to be a standout year. The blog crossed a significant milestone, recording well over half a million views during the year. That growth has been driven entirely by reader interest and engagement, which makes it even more rewarding. As the year comes to a close, it feels like the right moment to look back and highlight the posts that resonated most strongly with readers.

As has become a bit of an annual tradition, here is a look at the most popular content from 2025.

Top 5 Most Viewed Posts of 2025

One interesting shift this year is that all of the most viewed posts were published during 2025 itself. In previous years, older evergreen articles often dominated the rankings, but this time new content clearly captured attention as it was published.

  1. Highlights from XGMF's Conference to Advance Millimetre Wave Technology, Jan 2025
  2. Testing, Refining, and Improving Stratospheric Connectivity: NTT Docomo’s HAPS Trials, Apr 2025
  3. How Do Apple AirTags Work?, Mar 2025
  4. The Internet Story: A Deep Dive into How the Internet Works, Apr 2025
  5. Seamless 5G Connectivity Across Germany on Deutsche Bahn, May 2025

What stands out here is the mix. Deep technical topics such as millimetre wave and HAPS sit alongside explainers aimed at a broader audience, as well as real world deployment stories. That balance seems to reflect what readers value most, understanding both the theory and how it plays out in practice.

Top 5 Most Viewed Posts of All Time

While 2025 content performed exceptionally well, some older articles continue to attract steady interest year after year. These posts have become long term reference pieces, regularly discovered by new readers.

The all time top five reflects enduring curiosity around satellite networking, Wi-Fi evolution and core mobile network architecture.

  1. Laser Inter-Satellite Links (LISLs) in a Starlink Constellation, Feb 2022
  2. IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8, Mar 2023
  3. CSI-RS vs SRS Beamforming, Mar 2021
  4. High-level Architecture Introduction of Mobile Cellular Networks from 2G to 5G, Aug 2019
  5. IEEE 802.11be Extremely High Throughput (EHT), a.k.a. Wi-Fi 7, Nov 2020

It is reassuring to see that well explained fundamentals continue to hold their value, even as the industry moves quickly from one generation of technology to the next.

Looking Ahead to 2026

As preparations begin for another year of writing and exploration, a big thank you goes to everyone who reads, shares, comments and challenges the ideas discussed on the blog. That interaction is what keeps the content grounded and relevant.

The plan for 2026 is to continue digging into connectivity technologies that are shaping networks today, while also keeping an eye on what is coming next. As always, suggestions and topic ideas are very welcome.

Wishing you a connected, curious and innovative year ahead.

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...
