The FCC said it has approved a license for T-Mobile and SpaceX's Starlink to provide supplemental coverage to cover internet dead zones. Reuters reports: The license marks the first time the FCC has authorized a satellite operator collaborating with a wireless carrier to provide supplemental telecommunications coverage from space on some flexible-use spectrum bands allocated to terrestrial service. The partnership aims to extend the reach of wireless networks to remote areas and eliminate "dead zones." T-Mobile and SpaceX announced a partnership in 2022 and in January the first set of satellites supporting the partnership was launched into low-Earth orbit with SpaceX's Falcon 9 rocket. "The FCC is actively promoting competition in the space economy by supporting more partnerships between terrestrial mobile carriers and satellite operators to deliver on a single network future that will put an end to mobile dead zones," said FCC Chair Jessica Rosenworcel.

The Rich Country With the Worst Mobile-Phone Service

15 novembre 2024 à 19:25
Economist: Britain has long been a pioneer in telecoms. In 1837 it built the world's first commercial telegraph; the first transatlantic call was placed from London in 1927; in 1992 a British programmer sent the first text message to a mobile phone. Today it lags rather than leads. According to figures provided to The Economist by Opensignal, a research firm, Britain ranks 46th for download speeds out of the 56 developed and developing countries for which there are data. That gives it the worst mobile service in the rich world. Some of this is due to demand. Over the past three years data usage on mobile devices has doubled as people stream films and play games. The busiest parts of cities often lack mobile reception because the system is at capacity. But mainly it is an issue of supply. British users of 5G are only on it 11% of the time. That puts Britain 43rd out of the 56 countries. This lacklustre performance is caused by a combination of government U-turns, insufficient investment and sclerotic planning.

Somebody Moved UK's Oldest Satellite, No-One Knows Who or Why

The UK's oldest satellite, Skynet-1A, mysteriously shifted from its original orbit above East Africa to a new position over the Americas, likely due to a mid-1970s command whose origins remain unknown. "The question is who that was and with what authority and purpose?" asks the BBC. From the report: "It's still relevant because whoever did move Skynet-1A did us few favours," says space consultant Dr Stuart Eves. "It's now in what we call a 'gravity well' at 105 degrees West longitude, wandering backwards and forwards like a marble at the bottom of a bowl. And unfortunately this brings it close to other satellite traffic on a regular basis. "Because it's dead, the risk is it might bump into something, and because it's 'our' satellite we're still responsible for it," he explains. Dr Eves has looked through old satellite catalogues, the National Archives and spoken to satellite experts worldwide, but he can find no clues to the end-of-life behaviour of Britain's oldest spacecraft. It might be tempting to reach for a conspiracy theory or two, not least because it's hard to hear the name "Skynet" without thinking of the malevolent, self-aware artificial intelligence (AI) system in The Terminator movie franchise. But there's no connection other than the name and, in any case, real life is always more prosaic.

A pre-dawn statewide alert about an officer shooting in Hall County triggered over 4,500 complaints to the Federal Communications Commission. The 4:52 a.m. "Blue Alert" on October 4 awakened millions of Texans, many living hundreds of miles from the incident location, to notify them about suspect Seth Altman. Air traffic controllers, healthcare workers, and other professionals reported safety concerns from sleep disruption, according to records obtained by 404 Media. Multiple residents told the FCC they disabled all emergency notifications in response, potentially compromising public safety for future alerts.

Starlink Enters National Radio Quiet Zone

Starlink has launched home Internet service to 99.5% of residents in the National Radio Quiet Zone (NRQZ) after a multi-year collaboration with the National Radio Astronomy Observatory to minimize interference with radio telescopes. "The vast majority of people within the areas of Virginia and West Virginia collectively known as the National Radio Quiet Zone (NRQZ) can now receive high speed satellite Internet service," the National Radio Astronomy Observatory and Green Bank Observatory announced said. "The newly available service is the result of a nearly three-year collaborative engineering effort between the US National Science Foundation (NSF), SpaceX, and the NSF National Radio Astronomy Observatory (NSF NRAO), which operates the NSF Green Bank Observatory (NSF GBO) in West Virginia within the NRQZ." Ars Technica reports: There's a controversy over the 0.5 percent of residents who aren't included and are said to be newly blocked from using the Starlink Roam service. Starlink markets Roam as a service for people to use while traveling, not as a fixed home Internet service. The Pendleton County Office of Emergency Management last week issued a press release (PDF) saying that "customers with the RV/Roam packages had been using Starlink for approximately two years throughout 100% of the NRQZ. Now, the 0.5% have lost coverage after having it for two years. This means that a large section of southeastern Pendleton County and an even larger section of northern Pocahontas will NOT be able to utilize Starlink." PCMag wrote that "Starlink is now live in 42 of the 46 cell areas around the Green Bank Observatory's telescopes." Pendleton County Emergency Services Coordinator Rick Gillespie told Ars today that Roam coverage was cut off in the remaining four cell areas. "After the agreement, we all lost effective use within the four cells," Gillespie told Ars in an email. Gillespie's press release said that, "in many cases, Starlink was the only Internet provider option residents and emergency responders had. This is unacceptable."

Arecibo Collapsed Because of Engineering Failures That Inspectors Failed To Spot

Par : BeauHD
31 octobre 2024 à 10:00
An anonymous reader quotes a report from Behind the Black: According to a new very detailed engineering analysis into the causes of the collapse of the Arecibo radio telescope in Puerto Rico in 2020, the failure was caused first by a surprising interaction between the radio electronics of Arecibo and the traditional methods used to anchor the cables, and second by a failure of inspections to spot the problem as it became obvious. The surprising engineering discovery is illustrated [here (PNG)]. The main antenna of Arecibo was suspended above the bowl below by three main cables. The figure shows the basic design of the system used to anchor the cable ends to their sockets. The end of the cable bunches would be inserted into the socket, spread apart, and then zinc would be poured in to fill the gap and then act as a plug and glue to hold the cables in place. According to the report, this system has been used for decades in many applications very successfully. What the report found however was at Arecibo over time the cable bunch and zinc plug slowly began to pull out of the socket, what the report labels as "zinc creep." This was noted by inspectors, but dismissed as a concern because they still believed the engineering margins were still high enough to prevent failure at this point. In fact, this is exactly where the structure failed in 2020, with the first cable separating as shown in August 2020. The second cable did so in a similar manner in November 2020. The report concluded that the "only hypothesis the committee could develop that provides a plausible but unprovable answer to all these questions and the observed socket failure pattern is that the socket zinc creep was unexpectedly accelerated in the Arecibo Telescope's uniquely powerful electromagnetic radiation environment. The Arecibo Telescope cables were suspended across the beam of 'the most powerful radio transmitter on Earth.'"

Federal Communications Commission Chair Jessica Rosenworcel outlined a vision for universal connectivity last week that merges satellite and ground-based networks. The FCC recently became the first regulator to establish a framework for supplemental coverage from space (SCS). "Satellites may be in our skies, but they are the anchor tenant in our communications future," said Rosenworcel, calling for seamless integration of fiber, cellular, wireless, and satellite infrastructure into a unified network. The vision comes as the FCC's Affordable Connectivity Program recently ended due to funding depletion.

"Boeing has had a series of issues over the past few years," writes Slashdot reader quonset. "From planes crashing, lost service records, to a recent strike which cost them $6 billion, now comes word a satellite they made has exploded in space." CBS News reports: The Intelsat 33e satellite, which was launched in 2016 and provides communications across Europe, Asia and Africa, experienced "an anomaly" on Saturday, Intelsat said in a news release. Attempts were made to work with Boeing and repair the satellite, but on Monday, the U.S. Space Force confirmed that the satellite had exploded. The satellite's breakup left some customers without power or communications services. Intelsat said it is working with third-party providers to limit service interruptions, and is in communication with customers. Since the breakup, the U.S. Space Force is now tracking "around 20 associated pieces" of the satellite in space. The agency said that there are "no immediate threats" and routine assessments to ensure safety are ongoing. Russia's space agency, Roscosmos, said it had recorded "more than 80 fragments" of the destroyed satellite. Analysis of the pieces' trajectory determined that the destruction of the satellite was "instantaneous and high-energy," Roscosmos said.

Longtime Slashdot reader schwit1 shares a report from Via Satellite: SpaceX submitted a request to the FCC to modify the second generation, Gen2, of its Starlink satellite system with changes that SpaceX said will allow the constellation to deliver gigabit-speed broadband. SpaceX submitted the filing to the FCC on Oct. 11, and it was made public on Tuesday. The operator wants to make changes to the orbital configuration and operational parameters, and requests modifications for its Gen2 frequency authorization. These modifications "will enable the Gen2 system to deliver gigabit-speed, truly low-latency broadband and ubiquitous mobile connectivity to all Americans and the billions of people globally who still lack access to adequate broadband," Jameson Dempsey, SpaceX director of Satellite Policy said in the filing. For comparison, Starlink's current statement on service speeds is that users typically experience download speeds between 25 and 220 Mbps, and a majority of users experience speeds over 100 Mbps. In 2022, the FCC partially approved SpaceX to deploy a Gen2 Starlink constellation of up to 7,500 satellites for fixed satellite services (FSS) in the Ku- and Ka-bands, then later authorized Gen2 operations using additional frequencies in the E- and V-bands. SpaceX reported that since then, it has deployed more than 3,000 satellites in the Gen2 system and the full Starlink constellation serves more than four million people.

India Agrees With Musk in Satellite Spectrum Allocation Row

India announced on Tuesday it would allocate spectrum for satellite services through administrative means rather than auction, a decision that aligns with recent comments by Elon Musk and rebuffs lobbying efforts by the country's largest telecom operators. From a report: Jyotiraditya Scindia, India's Communications Minister, stated on Tuesday evening: "Spectrum for satcomm is shared spectrum, and cannot be auctioned. The administrative allocation of satellite spectrum is practised worldwide." This move favors Musk's Starlink and Amazon's Project Kuiper, who have advocated for shared spectrum allocation. It contradicts Reliance Jio's position, led by India's richest man Mukesh Ambani, which has pushed for auctions to ensure a "level playing field." Musk had warned on Monday that satellite spectrum auctions "would be unprecedented," citing long-standing ITU designations of shared satellite spectrum.

8 octobre 2024 à 00:02
An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission gave Starlink and T-Mobile emergency authority to provide satellite-to-phone coverage in areas hit by Hurricane Helene. "SpaceX and T-Mobile have been given emergency special temporary authority by the FCC to enable Starlink satellites with direct-to-cell capability to provide coverage for cell phones in the affected areas of Hurricane Helene," SpaceX said yesterday. "The satellites have already been enabled and started broadcasting emergency alerts to cell phones on all networks in North Carolina. In addition, we may test basic texting (SMS) capabilities for most cell phones on the T-Mobile network in North Carolina." SpaceX warned of limits since the service isn't ready for a commercial rollout. "SpaceX's direct-to-cell constellation has not been fully deployed, so all services will be delivered on a best-effort basis," the company said. Starlink is being used to provide wireless emergency alerts to cell phones from all carriers in North Carolina, according to Ben Longmier, senior director of satellite engineering for SpaceX. "We are also closely monitoring Hurricane Milton and standing by ready to take action in Florida," he wrote. The FCC said (PDF) the approval "enabl[es] SpaceX to operate Supplemental Coverage from Space (SCS) in the 1910-1915 MHz and 1990-1995 MHz frequency bands leased from T-Mobile in areas affected by the Hurricane Helene." An FCC spokesperson told Ars that the approval is for all areas affected by Hurricane Helene, although it's only active in North Carolina so far. The FCC also said (PDF) that it is granting "special temporary authorities to licensees and issuing rule waivers to help communications providers maintain and restore service, support emergency operations, and assist public safety, including search and rescue efforts." Separately, the FCC last week waived (PDF) certain Lifeline program eligibility rules to help people in disaster areas (PDF) apply for discounted phone and broadband service.

30 septembre 2024 à 18:41
DirecTV has agreed to acquire struggling rival Dish Network, creating a satellite TV behemoth with nearly 20 million subscribers. The complex transaction, announced Monday, involves private equity firm TPG acquiring a majority stake in DirecTV from AT&T for $7.6 billion. DirecTV will then purchase Dish for $1 and assume its debt. The deal provides a lifeline for Dish, which faces $2 billion in debt due November with only $500 million in available cash. EchoStar, Dish's parent company, will retain its wireless spectrum investments and operate independently. Subject to regulatory approval and creditor agreement, the merger is expected to close in late 2025. DirecTV and TPG will provide $2.5 billion to cover Dish's immediate financial needs. The deal's fate remains uncertain, as a similar 2002 merger attempt was blocked on antitrust grounds.

Longtime Slashdot reader penciling_in shares a report from CircleID: Starlink, SpaceX's satellite-based internet service, has hit a major milestone by surpassing 4 million subscribers worldwide. SpaceX confirmed the news on Thursday after company President Gwynne Shotwell hinted earlier in the week that the service would reach the mark within days. Since its beta launch in October 2020, Starlink has rapidly scaled, growing from 1 million subscribers by December 2022, to 2 million by September 2023, and now 4 million just months later. The service operates through a vast constellation of nearly 6,000 satellites, providing satellite internet to users in almost 100 countries, including expanding into previously underserved regions like Africa and the Pacific islands. [While competition from OneWeb and Amazon's Project Kuiper looms, Starlink remains the market leader. However, challenges like slowing U.S. growth and concerns over satellite interference with radio astronomy persist.] Starlink is coming to United Airlines' entire fleet and Hawaiian Airlines Airbus flights. Air France also announced yesterday that it, too, will support free Starlink Wi-Fi on all its aircraft.

Hot on the heels of United Airlines' Starlink announcement, Hawaiian Airlines said it, too, is offering "fast and free Starlink Wi-Fi" across its entire Airbus fleet. CNET reports: Hawaiian Airlines is now the first major carrier to use Elon Musk's satellite internet service, which taps more than 7,000 satellites in low earth orbit to deliver high-speed internet worldwide. "In Starlink's low earth orbit constellation of advanced satellites, the latest of which utilize a revolutionary laser mesh network, we found an ideal solution to ensure reliable, high-speed, low-latency Wi-Fi on transpacific flights," a Hawaiian Airlines representative told CNET. "Working with Starlink has allowed us to offer a fast and consistent in-flight connectivity experience that meets our high standard for guest service." The company first debuted Starlink on its planes in February on a flight from Honolulu to Long Beach, California. It first struck a deal with Starlink in 2022 and has now completed installation across its entire Airbus fleet, which includes 24 A330 planes and 18 A321neos. Hawaiian Airlines will also deploy the service on its two Boeing 787-9 planes, but not its Boeing 717 aircraft, which are used on shorter flights between the Hawaiian Islands.
