Will Electronically Steered Antennas Replace Parabolic Antennas in Satellite Ground Stations?

Three recent developments make me wonder whether we are on the cusp of a shift in satellite ground station technology from parabolic to electronically steered antennas (ESAs). The U.S. Space Force operates the Satellite Control Network, with 19 parabolic antennas at seven locations around the world.

FCC Touts 6G

The U.S. Federal Communications Commission (FCC) has seemingly joined forces with the marketing arm of the cellular industry in declaring that the spectrum between 7-16 GHz is now considered to be 6G. Chairman Jessica Rosenworcel recently announced that the agency would soon begin looking at the uses for this spectrum for mobile broadband.

Australian Government Issues New Guidelines to Address 5G Security Concerns in Smart Cities

The Australian Signals Directorate (ASD) has issued a new set of guidelines warning about the security risks posed by the use of 5G technology in so-called Smart Cities. The ASD's concerns align with those of the Five Eyes security alliance, which has warned that the interconnected nature of a fully connected city makes it vulnerable to cyberattacks.

The Problem Of 5G Hype

I'm writing this as the 5G hype cycle reaches a new crescendo. What is most striking is how few of those touting 5G (or "private 5G") is how little technical detail there is beyond saying it is the next generation of cellular protocols. Yes, one can look at volumes of specifications with myriad options and flavors but no sense of 5G as such. That alone should make one suspicious - why does one have to eschew wires to get 5G?

An Extortionists Fire Sale of TikTok to a US Company Would Be Un-American and Futile

In the latest twist of the US-China spat, President Trump has his sights on TikTok, the short-form video-sharing platform and ByteDance subsidiary. On July 31, President Trump threatened to ban TikTok because it was a threat to US national security. On August 6, he made good on his threat when he signed an Executive Order to that effect. President Trump tightened the screws with an August 14 Executive Order requiring ByteDance to divest its assets in the US and destroy any TikTok data on its US users within 90 days.

Fixed Wireless in Cities

I am often asked by cities about the option of building a municipal fixed wireless broadband network. As a reminder, fixed wireless, in this case, is not a cellular system but is the point-to-multipoint technology used by wireless Internet service providers (WISPs). My response has been that it's possible but that the resulting network is probably not going to satisfy the performance goals most cities have in mind.

Starlink Comes to Africa - Markets and Competition

SpaceX Starlink Internet service will be available in several African nations in the second quarter of this year, and the price in Nigeria has been announced -- $600 for the "residential" terminal and a monthly fee of $43. Is there a market for Starlink at that price in Nigeria and other Sub-Saharan African nations? The IMF projects a GDP per capita of $2,580 for Nigeria this year (and $1,900 in Sub-Saharan Africa and $2,260 for Africa overall) so the market for individual consumer accounts will be much smaller than in what the IMF refers to as "advanced economies."

Getting Serious About Satellite Texting

One of the more interesting telecom announcements at the CES electronics show in Vegas was the announcement from the partnership of Qualcomm and Iridium of plans to bring satellite texting capability to many more cell phones and other devices. We've already seen a few other announcements recently of the ability to make emergency text calls when out of reach of cell coverage.

The Disappointment of 5G

Karl Bode recently wrote an excellent article highlighting the overhyping of wireless technologies. He's right, and for the last twenty years, we've been told that a world-changing wireless technology is coming soon, but none ever materialized. No wireless technology has been a bigger flop than 5G when comparing the hype to the eventual reality. The hype for 5G was amazingly over-the-top.

A New Definition of 6G

We now know how wireless carriers are going to continue the string of new G generations of cellular technology. 5G was originally defined to include spectrum up to 90 GHz or 100 GHz. In the last few years, international standards bodies have been developing new 6G standards in what is called the terahertz wavelengths between 100 GHz and 1 THz.
