Is 5G Faster than 4G?

Ookla recently tackled this question in one of its research articles. Ookla compared the time it takes to load pages for Facebook, Google, and YouTube on cellphones using 4G LTE networks versus 5G networks. Ookla thinks that page load speed is a great way to measure cellphone experience. The time needed to load a web page is directly impacted by latency, which measures the lag between the time a phone requests a website and that website responds. more

Chinese Company Launches First Satellites for Massive Network to Rival Starlink

A Chinese state-backed company has successfully launched its first 18 satellites, marking the initial phase of a significant project to establish a vast orbital network intended to compete with Starlink, according to The China Securities Journal. more

Broadband Anywhere: The New Trend Bringing Connectivity to Campers and Remote Locations

A new broadband trend has quietly entered the market. Both Starlink and T-Mobile are advertising broadband that can be used practically anywhere and are aiming new products at campers, hikers, and others that go to remote locations. According to T-Mobile, this is a huge market, with 15 million households taking RV trips yearly and 59 million people camping. more

Geely Geespace Update - Global Centimeter-Level Positioning Services

Chinese automobile conglomerate Geely has made significant strides since I last wrote about their Geesat LEO constellation for mobile vehicle connectivity. They launched the first nine satellites in June 2022 and a second batch of eleven satellites in February 2024. The mass of the first nine satellites was 100 kg, and the mass of the second eleven was 130 kg, so they are not identical. more

Loving and Hating Starlink

I'm such an industry nerd that I sometimes read customer reviews of large ISPs just to see how the public perceives them. Most ISPs have more negative reviews than positive ones, and that's to be expected since people are more likely to complain when things go wrong than give praise when things are working as promised. more

Two New Chinese Internet Service Constellations and Their Market

China’s plans for low-Earth orbit Internet service constellations began with two projects, Hongyun (156 satellites) and Hongyan (864 satellites). These were eventually sidelined for Guowang, an ambitious, 12,992 satellite constellation that is expected to begin launching satellites this year. But, that is old news. China’s five-year plan designates satellite Internet as a strategic emerging industry and two new constellations have emerged, G60 (12,000 satellites) and Honghu–3 (10,000 satellites). more

Satellites Directly to Cellphones

AT&T and satellite company AST SpaceMobile announced a partnership to provide satellite cellular service directly from satellites to cellphones. This will provide a service that is much needed for the billions of remote users who are not in the range of a cell tower. This is an emerging industry that is still being referred to by different acronyms. more

Solar Storms Threaten Broadband and Power Grids: Understanding the Impacts and Preparations

Many readers will have seen recent news that the aurora borealis, or northern lights, were visible deep into the South for several days. This phenomenon is caused by a geomagnetic storm that is caused by strong solar flares. Solar flares can cause problems on Earth by emitting clouds of magnetized particles and hot plasma. more

Researchers Expose Privacy Risks in Apple and Starlink’s Geo-Location Data, Uncovering Military and Civilian Tracking

Researchers from the University of Maryland have revealed significant privacy and security concerns related to the way Apple and Starlink geo-locate devices. Their study found that Apple's Wi-Fi Positioning System (WPS) collects and publicly shares precise locations of Wi-Fi access points. more

A Transport Protocol’s Perspective on Optimizing Starlink Performance

Digital communications systems always represent a collection of design trade-offs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium. more

Starlink Service Is Great on (Some) Cruise Ships

I recently used Starlink on a cruise along the coast of Northwest Africa, and I'll summarize my experience below, but first let me explain why I put some in the title of this post. I posted the following request on the Reddit Cruise group: "What has been your experience of Starlink Internet service on Seabourn or other cruise lines? How was latency? Do video chats work smoothly? Games? etc." more

The Rise of WiFi Sensing and Its Implications for Home Security and Surveillance

It's incredibly hard to keep things private in the new digital age. There are far too many stories circulating about people who talked to a friend on the phone or texted about something and almost instantly got hit with ads for the subject of the conversation. And that happens without malware - no telling what information you're giving out if your devices have been infected with malicious software that is spying on you. more

Another G Generation: The Promise of 5.5G

I've read several articles coming out of the Mobile World Congress trade show in Barcelona, Spain, and one of the common threads is that there was a lot of talk about 5.5G (or 5G Advanced) - the next iteration of 5G. My first question on reading about this was to ask what new features are being discussed that were not part of the original announced promises of 5G. I went back and read a few of my blogs and other articles that were written when 5G was first announced. more

6G Collaboration by U.S. and Allies Against Authoritarian Control

The United States, along with key global partners, has formally committed to principles guiding the development of 6G technology, as announced by the White House. This move comes amidst a strategic contest to shape the future of wireless communication standards, driven by concerns over authoritarian regimes exerting greater control over the internet within their borders. more

China’s Satellite Internet Ambitions: A Quest to Rival SpaceX

launched a notable 67 commercial rockets in a single year, marking a significant effort to catch up with the United States, which led with 116 launches, primarily for SpaceX's Starlink project. more
