Anybody not involved in the telephone business will probably be surprised to find that the old TDM telephone networks are still very much alive and in place. The old technologies were supposed to be phased out and replaced by digital technologies. The FCC started talking about this before 2010. In 2013, Tom Wheeler, the FCC Chairman at the time, announced an effort to force the needed changes, which was dubbed the IP Transition. more
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
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
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
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
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
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
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
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
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
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
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
Broadband networks are stretched thin today due to the large numbers of adults and students working from home. There are many stories on the web that indicate that a lot of employees are not going to be going back to the office when the pandemic is over. Here are two stories about a trend towards more teleworking from the dozens that a Google search uncovered. more
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
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
