Rural Broadband Subsidy – What’s the Rush?

The Federal Communications Commission (FCC) has adopted procedures for Phase I of the Rural Digital Opportunity Fund (RDOF) auction, which will award up to $16 billion in support over ten years for the deployment of fixed broadband networks to homes and businesses in census tracks that are unserved by voice and broadband with download speeds of at least 25 Mbps.

Can SpaceX Launch 30,000 Second-Generation Starlink Satellites? Maybe

The bottom line is that success is not guaranteed, but neither is failure -- there is a non-zero probability of success. On May 26th, SpaceX applied for permission to launch 30,000 "second-generation" Starlink broadband Internet satellites. (Note that the software on Starlink satellites is updated about once a week). The application narrative states that the second-generation satellites will be configured...

Hassle Over LEOs

Every second, 4.5 billion people using computers and other electronic devices send 100,000 gigabytes of information to each other. Around 60% of the world's population has an Internet connection. North America and Europe have penetrations of 95% and 87%. But Asia and Africa do not yet get beyond 54% and 40%. On those continents, there are many remote areas where there is no Internet yet. At least no affordable Internet.

Canada Caves to the US, Blocks Huawei 5G (Inference)

Huawei is the strong favorite of Canadian network builders, for good products and extraordinary support. It displaced the incumbents at Bell Canada years ago and has a joint "Living Lab" in Vancouver with Telus. Huawei had already won the 5G contracts. It has a thousand researchers and spends a quarter billion dollars on Canadian R&D. It was a government decision.

The Costs of Trump’s 5G Wall

Over the past three years, Trump and his followers around Washington have begun to erect the equivalent of his Southern Border Wall around the nation's information network infrastructure - especially for 5G. The tactics are similar - keep out foreign invaders who are virtually sneaking across the borders to steal the nation's information resources and controlling our internet things. The tactics and mantras are almost identical.

Emerging Communications Technologies

A "New IP" framework was proposed to the ITU last year. This framework envisages a resurgence of a network-centric view of communications architectures where network-managed control mechanisms moderate application behaviors. It's not the first time that we've seen proposals to rethink the underlying architecture of the Internet's technology (for example, there were the "Clean Slate" efforts in the US research community a decade or so ago) and it certainly won't be the last.

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.

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.

SpaceX Applies for a Constellation Re-Design and Announces Beta Test Dates

This week SpaceX petitioned the FCC to reconfigure their Starlink constellation and Elon Musk outlined their beta testing plan. As shown below, the most significant configuration change is reducing the altitude of four of the five groups of orbital planes by around 50%. The total number of satellites and the number orbiting at a 53-degree inclination, which gives good coverage over relatively affluent regions, are not changed very much.

5G Security – Metrics of the Engaged

This past month on 03-06 March, the global industry sub-group that exists at the center of 5G security met virtually. It is known as SA3 within the 3GPP organization, and it met over a period of five days to deal with some of the most important 5G security requirements. 3GPP is a "partnership" created among all the world's major standards bodies, which over several decades has cooperatively developed and evolved by far the largest and most successful global electronic communications network.
