Starlink to Go - Stress Tested in Ukraine and Now Available to You

Russians have targeted Ukrainian electricity and communication infrastructure. In some areas, there may not be any utility poles left standing, and underground conduits may have been bombed to oblivion. Starlink has been an important tool for these brave people to coordinate their resistance to Putin's brutal invasion. Satellite communication doesn't require any middle-mile infrastructure. more

Using LEOs and GEOs

Once you head away from the areas serviced by modern terrestrial cable infrastructure, the available digital communications options are somewhat limited. Some remote areas are served using High-Frequency radio systems, using radio signals that bounce off the ionosphere to provide a long-distance but limited bandwidth service. Or there are satellite-based services based on spacecraft positioned in geostationary orbital slots. more

The Unprecedented Role of the Internet in the War in Ukraine

The impact of the Internet in the Russia-Ukraine war is unprecedented in speed and scope. The most visible example of this has been President Zelenskyy's use of social media and teleconferencing in his roles as Commander in Chief of the armed forces, a global diplomat, and a leader of the Ukrainian people. more

The Death of Millimeter-Wave Cellular?

Apple recently announced that it is not building millimeter-wave spectrum antennas into the next generation SE iPhone. Interestingly, this is a phone sold by Verizon, which spent a year advertising on TV and showing us speed tests on cellphones that were receiving gigabit speeds. more

Five Thousand SpaceX Starlink Terminals for Ukraine

On March 1, I wrote that a small number of SpaceX Starlink terminals had arrived in Ukraine, and they would be an important asset for distribution to selected government and resistance leaders and journalists. I didn't know who would get the terminals or how many there were, but it was a single truckload. A week or so later, we learned that two more shipments of terminals had arrived and fifty of them went to DTEK, a company struggling to repair Ukrainian electrical infrastructure. more

SpaceX to Launch Satellites for Competitor OneWeb

On March 2, Russia covered the US flag on the Roscosmos Space Agency rocket that was scheduled to launch 36 OneWeb broadband satellites on March 5. The Russians made two obviously untenable demands -- that OneWeb guarantee that the satellites would not be used for military purposes and the United Kingdom government remove its investment in the company. OneWeb declined, and the satellites were removed from the rocket. more

SpaceX Starlink in Ukraine – a Week Later

Last week I wrote about the arrival of a truckload of SpaceX Starlink terminals in Ukraine and their potential value to government and resistance leaders. A lot has happened in the ensuing week - this is an update. Last week, using Mike Puchol's Starlink tracking service, I found that users in Kyiv would have 100 percent uptime with connections through as many as nine satellites to ground stations in Turkey, Poland, and Lithuania. more

SpaceX Starlink Service in Ukraine Is an Important Government Asset

At 4:04 AM on February 26 Mykhailo Fedorov, Vice Prime Minister and Minister of Digital Transformation of Ukraine requested Starlink service from Elon Musk and at 2:45 PM on the 26th, Elon Musk tweeted "Starlink service is now active in Ukraine. More terminals en route." On February 28 at 12:29 PM Fedorov posted a photo of a truck load of terminals. (Kyiv is 10 hours ahead of California). more

SpaceX Is Testing Starlink Roaming

Last April, Elon Musk tweeted that Starlink "should be fully mobile later this year, so you can move it anywhere or use it on an RV or truck in motion." It is good to know that mobility with a standard dish is in the works, but it's not yet available. David Lang had been able to connect his Starlink terminal about fifteen miles from his home in Simi Valley, California, but when he brought it to my place in Carpinteria, California, about forty-three miles away and in a different coverage cell, it failed to connect. more

Starlink’s zoomready Rating Is Going Down

zoomready is open-source shareware I wrote to measure the suitability of an internet connection for teleconferencing. As you can see above, Starlink had an average zoomready rating of 2.66 out of a possible 3.0 over the four measured days. The problem is NOT bandwidth, which has fluctuated but stayed above the minimums needed for good teleconferencing. The problems are failures (most of them short), latency, and jitter. more
