A Cool Simulation of SpaceX’s Revised Satellite Broadband Plan

On November 15, the FCC approved a revision to the plan for Starlink, SpaceX's forthcoming broadband satellite service. The new plan reduces the number of satellites from 4,525 to 4,409 and lowers the altitude of the phase-1 satellites from 1,100 to 550 km. Mark Handley, a professor at University College London, has created videos based on simulations he ran of both the original and revised phase 1 plans. more

Geely’s LEO Constellation for Mobile Vehicle Connectivity

The Geely Holding Group (GHG) is a private Chinese conglomerate that is highly diversified but best known as an auto manufacturer that envisions itself as a "global mobile technology group." GHG announced this week that it has begun construction of an intelligent satellite production and testing facility that will include modular satellite manufacturing, satellite testing, satellite R&D, and cloud computing centers.

Update Mar 2, 2024:

Geely launched eleven satellites in the same 50-degree inclination plane as the first nine, but there was a considerable delay between the two launches. The first nine were launched in June 2022 and the second 11 were launched in February 2024. The delay may have been caused by a satellite re-design -- The mass of these satellites is 130 kg whereas the first nine satellites had masses of 100 kg.

The launch cadence will have to speed up if they are to reach their goal of beginning service with 72 t satellites next year. more

The Importance of the FCC

My friend Om Malik, dean of the telecom bloggers, posted on the importance of the Federal Communications Commission Chair appointment Obama will make as President... Om is dead on about the importance of this appointment. Decisions made by the five member FCC commission have had and will have an enormous effect not only on the tech sector but on the entire US and even the global economy. more

FCC Grants ISPs Temporary Access to Wireless Spectrum to Help Handle Demand During Pandemic

The FCC's Wireless Telecommunications Bureau today granted temporary spectrum access to 33 wireless Internet service providers serving 330 counties in the U.S. to help them serve rural communities facing an increase in broadband needs during the COVID-19 pandemic. more

The Role of Chronic Radio Interoperability Impediments in the Butler, PA Assassination Attempt

There are many inconvenient truths about radio spectrum sharing and transceiver interoperability that require full ventilation and resolution. Spectrum users want exclusive access and - news flash - they do not like to share! Campaign events, like the Trump Bulter, PA rally, require short notice, forced cooperation between and among federal, state, and local law enforcement officers, as well as a variety of other government agencies. more

The Google Telephone Company?

Google has undertaken a beta-test of a telephony platform that includes the opportunity to route incoming calls to multiple devices and telephone numbers as well as free domestic long distance service. Google offers a service that fits somewhere between computer-to-computer, Internet telephony and Voice over the Internet Protocol telephony with access to and from the public switched telephone network. These service categories present polar opposites for U.S. regulatory purposes... 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

FCC Approves White Space Devices: The Dawn of the Age of Opportunistic Spectrum Reuse

Yesterday will go down in history as a bellwether moment. Few among us will soon forget the excitement of Obama's election. But there was an equally historic vote yesterday that for geeks, policy analysts, and technologists represents an entirely new trajectory in telecommunications. In essence, the FCC has begun the transition from command-and-control, single-user spectrum licensure to a more distributed system that holds the potential to eliminate the artificial scarcity that prevented widespread access to the public airwaves since 1927. more

A 5G Community Network Strategy for Cuba (and Other Developing Nations)

In a previous post, I suggested that Cuba might be able to leap over 4G to 5G wireless infrastructure using satellite and terrestrial networks for backhaul. While that would require political and policy change, it would be a good fit with Cuban culture and skills. Before talking about Cuba, let me say a bit about wireless generations. Each mobile technology generation used new technology and enabled new applications. more

Alphabet’s Loon Goes Live With Its Commercial Internet Service in Kenya

Why Businesses Aren’t Hanging Up Landlines Yet

There was a recent article in the Wall Street Journal that noted that the business world still uses a lot of landline telephones. Landline telephones have been steadily disappearing from homes, but are still not gone. I see ISPs still selling a telephone line to 10% or more of passings, and surveys show that the average residential landline penetration rate is still somewhere between 15% and 20%. more

Will 2008 be the WiMAX Year?

There has recently been some good and bad news about WiMAX. On the good news part, an announcement made by the WiMAX Forum this month regarding the launching of the Mobile WiMAX certification program through which vendors can get their IEEE 802.16e-2005 equipment tested and possibly certified... On the bad news part, there was the Sprint-Clearwire breakup after three months of announcing a plan to join forces in building a nationwide WiMAX network in the US. Although it is anticipated that each company would carry on with its own WiMAX plans, analysts believe that the breakup would have negative impact on WiMAX deployment in the US... more

EFF to FCC: ‘Restoring Internet Freedom’ Plan Riddled With Technical Errors and Factual Inaccuracies
