Five years ago, any discussion of 5G included a vision that we'd end up with smart cars that were all connected with a ubiquitous 5G network that was going to be built everywhere. We're still waiting to see a real 5G network anywhere instead of the 4G LTE networks that are still being touted by every cellular company as 5G. The idea of a ubiquitous network capable of supporting smart cars died, but there is still an effort underway to use wireless technology to make car travel safer. more
In his January 12 SpaceX update, Elon Musk said the biggest goal for Starlink from a technical standpoint is to get the mean latency below 20 ms. He expanded by saying that given the speed of light, 8 ms is the absolute minimum latency for a satellite at 550 km. He believes they can optimize terrestrial and inter-satellite links, and minimize queueing delays and dropped packets, to recude the the rest of the time to below 10 ms. more
You may recall a number of years ago when Google experimented with delivering broadband from balloons in an effort labeled Project Loon. The project was eventually dropped, but a remnant of the project has now resurfaced as Taara - broadband delivered terrestrially by lasers. more
Starlink recently launched a new webpage that advertises the future ability to deliver text, voice, and data to 4G cell phones via satellite. The texting service is supposed to be available in 2024, with voice and data coming in 2025. The service will require a user to have a view of the open sky. more
A recent invitation to participate in a webinar to discuss ICANN's Role in Satellite Internet Governance as an enabler of UN Sustainable Development Goal (SDG) 9 prompted me to consider this issue. As a legal scholar with expertise in telecommunications infrastructure, I had much to say and discuss about the new mega-constellation phenomenon and its potential role in achieving SDG9, which, for me, is a multifaceted and fascinating subject. more
In an earlier post, I asked whether electronically steered antennas (ESAs) would replace parabolic antennas in satellite ground stations. I did some research and concluded that it is likely that they will. Next, I discussed the same question with ChatGPT and, while it made several false statements, it made a relevant point that I had overlooked. The relevant addition was positive, but the errors were troublesome, so I decided to try ChatGPT's competitor Google Bard. more
Karl Bode recently wrote an excellent article highlighting the overhyping of wireless technologies. He's right, and for the last twenty years, we've been told that a world-changing wireless technology is coming soon, but none ever materialized. No wireless technology has been a bigger flop than 5G when comparing the hype to the eventual reality. The hype for 5G was amazingly over-the-top. more
I am often asked by cities about the option of building a municipal fixed wireless broadband network. As a reminder, fixed wireless, in this case, is not a cellular system but is the point-to-multipoint technology used by wireless Internet service providers (WISPs). My response has been that it's possible but that the resulting network is probably not going to satisfy the performance goals most cities have in mind. more
"Saint Elon" is a bit much but ... It started with a tweet from Ukraine's Minister of Digital Transformation. The quoted text below is excerpts from How Elon Musk's Starlink satellite internet keeps Ukraine online in The Kyiv Independent. "Among the Ukrainian military, Elon Musk, the richest tech entrepreneur in the U.S., is often half-jokingly referred to as 'Saint Elon.'. The reason is Starlink, Musk's satellite communication system that keeps many Ukrainians, most importantly the military... more
The NASA-sponsored Artemis program is the first step in the next era of human exploration. Together with a large number of international government and academic partners as well as businesses -- and based on international standards -- NASA will establish a sustainable presence on the Moon. more
We got a recent analysis of Starlink broadband speeds from Ookla, which gathers huge numbers of speed tests from across the country. The U.S. average download speeds on Starlink have improved over the last year, from an average of 65.72 Mbps in 1Q 2021 to 90.55 Mbps in 1Q 2022. But during that same timeframe, upload speeds got worse, dropping from an average of 16.29 Mbps in 1Q 2021 to 10.70 Mbps in 1Q 2022. more
The Arctic region has largely been left out of the broadband arena in the past due to the high cost of building last-mile broadband infrastructure. The primary broadband available in the region has been provided for decades by Iridium Communications, which provided only low-bandwidth connections capable of supporting satellite phones and low-bandwidth monitoring devices. more
It wasn't too many years ago when you couldn't read an article about broadband infrastructure without hearing about the need for smart highway infrastructure that was going to enable self-driving cars. There were various versions of how this would happen, but the predominant concept was that 5G networks along roads would communicate with cars and would enable efficient and safe travel by eliminating driver error by taking the driver out of the equation. more
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
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
