The Fight Over 12 GHz Spectrum

For an agency that has tried to wash its hands from regulating broadband, the FCC finds itself again trying to decide an issue that is all about broadband. There is a heavyweight battle going on at the FCC over how to use the 12 GHz spectrum, and while this may seem like a spectrum issue, it's all about broadband. 12 GHz spectrum is key to several broadband technologies. First, this is the spectrum that is best suited for transmitting data between the earth and satellite constellations. more

Meet the Metaverse

I had already written this blog before Facebook announced it would be hiring at least 10,000 programmers to start moving the company towards the metaverse. I see the metaverse as one of the next big drivers of increased bandwidth usage. Wikipedia defines the metaverse as a collective virtual shared space created by the convergence of virtually enhanced physical reality and physically persistent virtual space, including the sum of all virtual reality worlds, augmented reality, and the Internet. In the most basic sense, the metaverse consists of online worlds where people interact through avatars. more

5G for Cars – an Idea That Won’t Die

An industry group calling itself 5G Americas has published a whitepaper that touts the advantages of a smart auto grid powered by 5G and the C-V2X technology. This technology is the car connectivity standard that much of the industry has gelled around, replacing the older DSRC standard. Over a decade ago, the FCC became so enamored over the idea of self-driving cars that the agency dedicated the 5.9 GHz spectrum band for the sole use of smart cars. more

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

Quantifying the Benefits of Fiber

Dr. Bento J. Lobo, an economist at the University of Tennessee at Chattanooga undertook a study to quantify the benefits of the municipally-owned fiber network in Chattanooga. Any citywide fiber network brings economic development to a community, but a municipally-owned system brings additional benefits because of the way that the business is more deeply integrated into the community. 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

What Does an Administration Change Mean for the FCC?

Just as the last change in administration changed the course of the FCC, so will the swing back to a Democratic administration. If you've been reading me for a few years, you know I am a big believer in the regulatory pendulum. Inevitably, when a regulatory agency like the FCC swings too far in any direction, it's inevitable that it will eventually swing back the other way. more

The Upload Speed Lie

In the 2020 Broadband Deployment Report, the FCC made the following claim. "The vast majority of Americans -- surpassing 85% -- now have access to fixed terrestrial broadband service at 250/25 Mbps". The FCC makes this claim based upon the data provided to it by the country's ISPs on Form 477. We know the data reported by the ISPs is badly flawed in the over-reporting of download speeds. Still, we've paid little attention to the second number. more

Is 5G a Race We Want to Win?

There is an interesting article recently published in the English version of a South Korean newspaper, the ChosunILBO, that talks about 5G in China. According to the article, the Chinese 5G rollout is an expensive bust. There are a number of interesting facts disclosed about the Chinese 5G rollout. First, it's clear that the rollout is using millimeter wave spectrum. more

Are Cable Companies a Broadband Monopoly?

One of the products my consulting firm offers are statistically valid surveys and conducting surveys has let us get a close look in many communities at the mix between cable broadband and telco DSL. In the last few years, the percentage of DSL subscribers in towns with a good cable company network has plummeted. It's not unusual to see DSL market penetration in bigger towns of 10% or less, meaning in most cases that the cable company has essentially won the competitive battle. 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
