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
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 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
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 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
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
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
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 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
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
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
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 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
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
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
