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.

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.

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.

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.

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).

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.

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.

Can Satellite Broadband Be Affordable?

When we first heard of the possibility of broadband from low-orbit satellites, there was a lot of speculation that the technology could bring affordable broadband to the masses around the globe. The latest announcement from Starlink shows that affordable broadband is probably not coming in the immediate future. Starlink announced a premium tier of service with a $500 monthly fee for 150-500 Mbps.

Update on China SatNet’s GuoWang Broadband Constellation – Can They Do It?

In 2020, China applied to operate GuoWang, a constellation of 12,992 low-Earth orbit (LEO) broadband Internet satellites, and in 2021, it became clear that it was intended to become China’s global LEO broadband constellation. Can they do it? Maybe, but it will take a long time. China does not have the capacity to launch 12,992 satellites today. I don’t know the mass of their planned satellites, but GuoWang is informally referred to as China’s answer to Starlink.

The Battle for IoT

There is an interesting battle going on to be the technology that monetizes the control of Internet of Things devices. Like a lot of tech hype, IoT has developed a lot slower than initially predicted -- but it's now finally becoming a big business. I think back to a decade ago when tech prognosticators said we'd soon be living in a virtual cloud of small monitors that would monitor everything in our life. According to those early predictions, our farm fields should already be fully automated, and we should all be living in the smart home envisioned by the Jetsons.
