Amazon’s Project Kuiper Successfully Tests Laser-Based Satellite Communication

Amazon's Project Kuiper has confirmed the use of laser-based inter-satellite links (OISL) for its satellite communication system. The technology has undergone successful testing in orbit, with data transmission speeds of 100 gigabits per second (Gbps) over a distance of 621 miles achieved.  more

Space-Ground Optical (Laser) Communication

SpaceX is equipping its new satellites with inter-satellite laser links (ISLLs). They now have over 8,000 optical terminals in orbit (3 per satellite) and they communicate at up to 100 Gbps. The other low-Earth orbit Internet service providers will follow SpaceX's lead. more

SpaceX Quietly Launches New Website for Cellular Starlink Service

SpaceX has unveiled its new "Starlink Direct to Cell" service, aimed at providing cellular connectivity globally via its Starlink satellite network. The newly launched website promotes the service with the promise of "Seamless access to text, voice, and data for LTE phones across the globe." more

Satellite Broadband Rivals: Beyond Starlink’s Dominance

Starlink gets almost all of the satellite press in the U.S., which is fair since the company now serves many homes and RVs with broadband. The company currently has over 4,600 active satellites in orbit, and if it sticks with its original business plan, it will eventually have 30,000. But there are a few other satellite companies working in the broadband space that don't get the press. more

Amazon Launched Its First Two Internet Satellites Into Orbit

Amazon launched its debut prototype satellites, Kuipersat-1 and Kuipersat-2, from Florida's Cape Canaveral on Friday. This marks the tech giant's initial foray into space, aiming to rival SpaceX's Starlink broadband network.  more

In Search of the Killer 5G App

AT&T and Comcast recently joined forces and joined the 5G Open Innovation Lab. This is a venture that has been funding start-ups and others working in 5G research. Along with looking to improve 5G edge technology, a primary goal of the OAI Lab is to search for killer apps for 5G. The two big companies join the other founding members of the effort, which includes Dell, Intel, Microsoft, Deloitte, and Nokia. more

Will Telesat Survive?

In 2017, Telesat, an established Canadian geostationary satellite operator, announced a planned low-Earth orbit Internet service constellation. The plan called for 117 satellites with inter-satellite laser links in a mix of inclined and polar orbits, enabling global coverage. more

Ukraine’s Increasing Dependence on Starlink Sparks Concern Over Musk’s Unilateral Control

Elon Musk's satellite internet technology, Starlink, has become an essential component of Ukraine's communication infrastructure, causing rising concerns among officials regarding their heavy reliance on this single source. Starlink, a product of Musk's SpaceX, has been instrumental in Ukraine's battle decision-making process amid the Russian invasion.  more

SpaceX Set to Launch Jupiter 3, the World’s Largest Commercial Communications Satellite, on Falcon Heavy Rocket

SpaceX is set to make history this Wednesday, July 26, by launching the largest commercial communications satellite to date, the Jupiter 3, using its Falcon Heavy rocket. more

Amazon Propels Into the Satellite Internet Race With New $120 Million Florida Facility

In an ambitious move, Amazon, in collaboration with state officials, has declared its plans to erect a high-tech satellite processing facility at NASA's Kennedy Space Center in Florida. Backed by $120 million budget, this expansive 100,000-square-foot complex will be the keystone of Amazon's Kuiper initiative. more

Using 42 GHz Spectrum for Broadband

The U.S. Federal Communications Commission circulated draft rules to govern the lower 42 GHz spectrum (between 42-42.5 GHz). This is within the range of spectrum referred to as millimeter wave spectrum. This is one of the more unusual FCC spectrum deliberations because this spectrum is totally empty -- there is nobody currently authorized by the FCC to use the spectrum band. The FCC is starting this deliberation with a clean slate. more

IEEE Approves 802.11bb Standard, Boosting Global Adoption of Light-Based Li-Fi Communications

The Institute of Electrical and Electronics Engineers (IEEE) has announced the inclusion of 802.11bb, a standard for light-based wireless communications. This new standard is seen as a major boon to global Li-Fi companies as it promises to expedite the rollout and acceptance of this innovative data transmission technology. more

Scientists Transmit Terabits Per Second Through Air, May Replace Undersea Cables

Scientists from ETH Zurich and their European partners have demonstrated a groundbreaking capability for transmitting several tens of terabits per second, despite considerable air turbulence. This feat was accomplished with lasers over a distance between the Jungfraujoch mountain peak and the city of Bern in Switzerland. The technology could potentially eliminate the need for expensive undersea cables, currently forming the backbone of the Internet. more

Satellite Spectrum Showdown: Musk’s Starlink vs. Ambani’s Reliance Jio in the Race for India’s Broadband Future

Elon Musk's quest to expand his Starlink satellite broadband service into India faces significant pushback from Mukesh Ambani, Asia's wealthiest individual and head of Indian telecom giant Reliance Jio. more

Will Electronically Steered Antennas Replace Parabolic Antennas in Satellite Ground Stations? (ChatGPT-Assisted Version)

In a previous post, I asked whether electronically steered antennas (ESAs) would replace parabolic antennas in satellite ground stations. I read a few articles suggested by others and by Google search, used some common sense, produced a list of advantages of ESAs, and concluded that it was likely they would eventually replace parabolic antennas for many applications. more
