There are many inconvenient truths about radio spectrum sharing and transceiver interoperability that require full ventilation and resolution. Spectrum users want exclusive access and - news flash - they do not like to share! Campaign events, like the Trump Bulter, PA rally, require short notice, forced cooperation between and among federal, state, and local law enforcement officers, as well as a variety of other government agencies. more
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
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
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
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
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
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 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
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
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
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
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
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
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
As was the case in the US during World War II, civilian volunteers are making important contributions to the Ukrainian war effort. On February 8, 2022, the first truckload of Starlink terminals arrived in Kyiv. A week later they were being used. By April 2022, there were 5,000 terminals in Ukraine, and 42,000 as of April 2023. (At this point, SpaceX and Ukraine have gone silent. Neither ChatGPT4, Gemini, Copilot, Perplexity, nor I could not find a current terminal count). more
