Civilian Tech Mobilization in Ukraine

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

Supporting Rural Cell Towers

I work with a lot of ISPs that own rural fiber. Some rural network owners have been successful in providing fiber to cell sites near their networks over the last decade. A few sell directly to a cellular carrier, but most of these connections are sold to an intermediate carrier that bundles together cellular connections across a large geographic area. more

Amazon Project Kuiper vs SpaceX Starlink

In 2019, I wrote that Amazon would be a formidable satellite-ISP competitor. I still think so, but I didn't expect it would be over four years until they launched the first test satellites. In the meantime, SpaceX has put over 5,000 satellites in orbit and has over two million Starlink customers. Amazon has permission to launch 3,236 satellites. more

Wi-Fi Alliance Has Officially Confirmed Wi-Fi 7 Standard; Certification Now Underway for New Devices

The Wi-Fi Alliance has officially certified devices supporting Wi-Fi 7, the highly anticipated next generation of wireless home internet. Starting in 2024, phones, laptops, and routers equipped with this standard are expected to deliver significant speed and efficiency gains compared to Wi-Fi 6E. more

SpaceX Launches Starlink Satellites for Global Cellular Coverage

SpaceX successfully launched 21 satellites, including the first six Starlink satellites equipped with "Direct to Cell" capabilities. These advanced satellites aim to offer seamless global access to texting, calling, and browsing for mobile network operators worldwide, eliminating dead zones with a space-based cellphone tower. more

An Update on Satellite Broadband

Ookla recently published a blog that looks at the speed performance of satellite broadband, focusing mostly on Starlink. I haven't looked at this broadband sector for a while and thought it was time for an update. Starlink has had a busy year. At the end of November, the company had 5,500 satellites in orbit, up from over 3,200 at the end of 2022. The first constellation is still slated to reach almost 12,000 satellites, and the company has tentative permission from the FCC to extend to 42,000. more

Amazon’s Project Kuiper Successfully Tests Laser-Based Satellite Communication

Amazon's Project Kuiper has confirmed the use of laser-based inter-satellite links (OISL) for its satellite communication system. The technology has undergone successful testing in orbit, with data transmission speeds of 100 gigabits per second (Gbps) over a distance of 621 miles achieved.  more

Space-Ground Optical (Laser) Communication

SpaceX is equipping its new satellites with inter-satellite laser links (ISLLs). They now have over 8,000 optical terminals in orbit (3 per satellite) and they communicate at up to 100 Gbps. The other low-Earth orbit Internet service providers will follow SpaceX's lead. more

SpaceX Quietly Launches New Website for Cellular Starlink Service

SpaceX has unveiled its new "Starlink Direct to Cell" service, aimed at providing cellular connectivity globally via its Starlink satellite network. The newly launched website promotes the service with the promise of "Seamless access to text, voice, and data for LTE phones across the globe." more

Satellite Broadband Rivals: Beyond Starlink’s Dominance

Starlink gets almost all of the satellite press in the U.S., which is fair since the company now serves many homes and RVs with broadband. The company currently has over 4,600 active satellites in orbit, and if it sticks with its original business plan, it will eventually have 30,000. But there are a few other satellite companies working in the broadband space that don't get the press. more

Amazon Launched Its First Two Internet Satellites Into Orbit

Amazon launched its debut prototype satellites, Kuipersat-1 and Kuipersat-2, from Florida's Cape Canaveral on Friday. This marks the tech giant's initial foray into space, aiming to rival SpaceX's Starlink broadband network.  more

In Search of the Killer 5G App

AT&T and Comcast recently joined forces and joined the 5G Open Innovation Lab. This is a venture that has been funding start-ups and others working in 5G research. Along with looking to improve 5G edge technology, a primary goal of the OAI Lab is to search for killer apps for 5G. The two big companies join the other founding members of the effort, which includes Dell, Intel, Microsoft, Deloitte, and Nokia. more

Will Telesat Survive?

In 2017, Telesat, an established Canadian geostationary satellite operator, announced a planned low-Earth orbit Internet service constellation. The plan called for 117 satellites with inter-satellite laser links in a mix of inclined and polar orbits, enabling global coverage. more

Ukraine’s Increasing Dependence on Starlink Sparks Concern Over Musk’s Unilateral Control

Elon Musk's satellite internet technology, Starlink, has become an essential component of Ukraine's communication infrastructure, causing rising concerns among officials regarding their heavy reliance on this single source. Starlink, a product of Musk's SpaceX, has been instrumental in Ukraine's battle decision-making process amid the Russian invasion.  more

SpaceX Set to Launch Jupiter 3, the World’s Largest Commercial Communications Satellite, on Falcon Heavy Rocket

SpaceX is set to make history this Wednesday, July 26, by launching the largest commercial communications satellite to date, the Jupiter 3, using its Falcon Heavy rocket. more
