Computing Clouds in Orbit – A Possible Roadmap

Last week, I predicted that much of the Internet and most cloud datacenters would launch into space in the next ten years. Today the only part of the Internet in space is a very small amount of "bent-pipe" access: signals which go from a user to a satellite and bounce back down to a ground station which feeds them into the terrestrial internet where all processing is done and all queries answered by internet-connected servers, many of them in cloud data centers. more

New Innovations in Free Space Optics

I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings. more

Avoiding Low-Earth Orbit Collisions – the Clock Is Ticking

There was a recent dispute between OneWeb and SpaceX regarding the possibility of a collision between two of their low-Earth orbit (LEO) satellites. OneWeb's satellite (OneWeb-1078) was launched on March 25 and headed for its orbit at an altitude of 1,200 km when, in early April, it passed near a SpaceX satellite (Starlink-1546) in orbit at about 450 km. There was no collision, but subsequently, OneWeb's government affairs chief Chris McLaughlin said... more

Telling the Truth About 5G

I still run across articles that extol the supposed wonders of 5G. The most recent, published in Gizmodo asks "How 5G Could Replace Your Home Broadband Connection". I was surprised to see an article like this in a tech-oriented site because the article gets most of the facts wrong about 5G - facts that are not hard to verify. This article talks about 5G having "faster download speeds, faster upload speeds, more bandwidth, and lower latency" than landline broadband. more

Trump’s Parting NTIA 5G Debacle

As Trump's horrific Administration of non-stop debacles and self-serving gambits headed toward the exit over the past few weeks, one last regulatory grab after another has been pushed out the door while the toddler-in-chief rants. Sure enough, the last of the 5G debacles just appeared in the Federal Register courtesy of the President's policy instrument, the National Telecommunication and Information Administration (NTIA). It was titled the 5G Challenge Notice of Inquiry. more

Is Laser Going to Be the Next Telecoms Frontier?

When I became involved in the telecoms industry back in the late 1970s, we were just seeing fiber optic cables being commercially developed by Corning. Over the following decades, I have been asked many, many times -- do we need fiber cables or wireless technologies, and what is next? During all that time, my answer has been that there was no other communication technology available in any commercial sense that would make either fiber optical or mobile technologies obsolete. more

An Update on LEO Satellites

A lot of rural America continues to hope that low orbit satellite (LEO) service will provide a broadband alternative. It's been a while since I've covered the status of the companies proposing to deploy constellations of satellites for providing broadband. In March, OneWeb filed for Chapter 11 restructuring when it was clear that the company could not raise enough cash to continue the research and development of the satellite product. more

SpaceX Launches Another Batch of 60 Starlink Internet Satellites

SpaceX launched its eighth Starlink mission via the Falcon 9 rocket on Wednesday, carrying 60 more satellites for its Internet satellite constellation, bringing the total in operation on orbit to 480. more

China Will Remember the U.S. Huawei War for a Generation

Only an idiot would believe that the U.S. is blocking TSMC manufacture of Huawei cell phone chips because of security fears. This is a commercial rivalry. The U.S. wants to put China's leading technology company out of business. We will fail, of course, at a price far higher than D.C. understands. The U.S. is ready for China's immediate countermeasures, even if Apple's stock price falls $hundreds of billions. But the long-run price will be devastating. more

The Evolution of 5G

Technology always evolves, and I've been reading about where scientists envision the evolution of 5G. The first generation of 5G, which will be rolled out over the next 3-5 years, is mostly aimed at increasing the throughput of cellular networks. According to Cisco, North American cellular data volumes are growing at a torrid 36% per year, and even faster than that in some urban markets where the volumes of data are doubling every two years. The main goal of the first-generation 5G is to increase network capacity to handle that growth. more

Broadband in China

For years I've been hearing how we are losing the broadband battle with China, so I decided to take a look at the current state of broadband in the country. The China Internet Network Information Center (CNNIC) publishes statistics about the state of broadband in the country, and I used the Statistical Report on Internet Development in China from August 2019 in writing this blog. more

Can 5G Replace WiFi?

Verizon recently posted a webcast with investors where Ronan Dunne, EVP and CEO of the Verizon Consumer Group said that he believed that 5G hotspots using millimeter wave spectrum would eventually displace WiFi in homes. He cites major benefits of 5G over WiFi. He believes that a 5G network will be more reliable and more secure. He thinks that people will value the safety that comes from having traffic inside their home being encrypted... more

5 Broadband Predictions for 2020

The 2010's have been nothing short of transformative in the broadband space. Despite disappointing deployment rates across the U.S., the past decade has been a period of exponential change and innovation. As we look toward the new decade, here are five key predictions based on current trends and developments in the broadband industry. more

Starlink Making a Space Grab

SpaceNews recently reported that Elon Musk and his low-orbit space venture Starlink have filed with the International Telecommunications Union (ITU) to launch an additional 30,000 broadband satellites in addition to the 11,927 now in the planning stages. This looks like a land grab and Musk is hoping to grab valuable orbital satellite paths to keep them away from competitors. more

The Myth of 5G and Driverless Cars

A colleague sent me an article that had been published earlier this year in MachineDesign magazine that predicts that driverless cars can't be realized until we have a ubiquitous 5G network. When looking for the original article on the web I noticed numerous similar articles like this one in Forbes that have the same opinion. These articles and other similar articles predict that high-bandwidth, low-latency 5G networks are only a few years away. more
