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

Elon Musk Interview: SpaceX, Starlink and His Motivation and Philosophy

Elon Musk packed a lot about SpaceX and Starlink into a 32-minute interview at the 2021 Mobile World Congress and ended with a discussion of his motivation and the roles of his three companies - SpaceX, Starlink, and Neuralnk. Let's start with the SpaceX and Starlink update and conclude with the philosophy and motivation. (Scroll to the end of the post for the video of the interview). more

An Attack on WiFi Spectrum

A little over a year ago, the FCC approved the use of 1,200 MHz of spectrum in the 6 GHz band for public use -- for new WiFi. WiFi is already the most successful deployment of spectrum ever. A year ago, Cisco predicted that by 2022 that WiFi will be carrying more than 50% of global IP traffic. These are amazing statistics when you consider that WiFi has been limited to using 70 MHz of spectrum in the 2.4 GHz spectrum band and 500 MHz in the 5 GHz spectrum band. more

The G7 and EU Join China in Call for Space Debris and Collision Regulation

Last month, the Chinese government published space situational awareness and traffic management regulations and procedures designed to guard against collisions in orbit and mitigate space debris, and this month, at the G7 summit, delegates from Canada, France, Germany, Italy, Japan, the USA, the UK, and the EU pledged to take action to tackle the growing hazard of space debris as our planet's orbit becomes increasingly crowded. more

Chinese Space Situational Awareness and Traffic Management Regulations and Procedures

In a recent issue of the Dongfang Hour Newsletter, Blaine Curcio pointed out that China's powerful State Administration of Science, Technology, and Industry for National Defence (SASTIND) had published a notice intended to promote the orderly development of microsatellites and strengthen safety management. The notice defines microsatellites as being below 1,000 kilograms, which would include those making up China's planned GwoWang/SatNet broadband constellation. more

SpaceX Starlink vs. Telesat Lightspeed

With 1,675 satellites launched and 500,000 requests for service in the United States alone, SpaceX Starlink clearly leads all would-be providers of low Earth orbit (LEO) internet service to consumers. However, it is arguable that Telesat Lightspeed is in the lead, or contending for the lead with SpaceX, in non-consumer enterprise, government, mobile backhaul, mobility and rural community markets. more

The Satellite Broadband is Heating Up

There is a lot of news recently about low-orbit satellite broadband. There is recent news concerning the three primary companies that will be vying in the space. First is Jeff Bezos Project Kuiper, which is still likely to get a brand name at some point. Project Kuiper has contracted with United Launch Alliance, a joint Boeing-Lockheed Martin venture, for the first nine broadband rocket launches. more

NSA Takes a Leadership Seat at the Global 5G Security Table

It has been a long time coming. In the world of global 5G security, there is only one principal forum. The somewhat cryptically named 3GPP SA3 is dedicated to 5G security and holding its 103rd meeting electronically next week from 17 to 28 May with 772 submitted documents and 189 participants registered. SA3 meets every 60 days and exists at the security center of an ecosystem of numerous technical groups encompassing many hundreds of companies, industry organizations, and government agencies worldwide. more

To 5.5G and Beyond

I recently saw an article in FierceWireless that reports that Huawei thinks we are going to need an intermediate step between 5G and 6G, something like 5.5G. To me, this raises the more immediate question about why we are not talking about the steps between 4G and 5G? The wireless industry used to tell the truth about cellular technology. You don't need to take my word for it... more

The $100 Billion National Broadband Plan for America

The new Biden Administration in the USA laid out a $100 billion proposal for broadband investment as part of its $2 trillion+ infrastructure plan. Under the proposal, the plan is to provide national broadband coverage. The Administration will use better competition measures, such as price transparency, the use of public utility infrastructure, and subsidies for low-income households to achieve its goals. more
