In today's hyperconnected world, seamless connectivity is no longer a luxury—it's an expectation. Yet despite the transformative impact of cellular and IoT technologies, much of the Earth's surface remains outside the reach of ground-based infrastructure. This gap underscores the urgent need for new solutions that can provide truly global coverage. Nonterrestrial networks (NTNs), particularly those leveraging low Earth orbit (LEO) satellites, represent a paradigm shift in global communications, extending connectivity to remote and underserved regions.
Major players such as SpaceX's Starlink, Amazon's Kuiper and OneWeb are investing heavily in satellite-based solutions to expand network access. Meanwhile, geopolitical tensions and national data security concerns are fueling an added sense of urgency to the evolution of satellite investment, deployment and ownership.
Delivering high-bandwidth, low-latency satellite communication presents formidable challenges, including spectrum efficiency, security, power consumption and seamless integration with terrestrial networks. Addressing these challenges is essential for NTNs to support next-generation applications and ensure global digital sovereignty.
The rapid deployment of LEO satellite constellations by private and government entities marks the beginning of a new phase in satellite communications. Unlike traditional geostationary satellites, which suffer from high latency and limited throughput, LEO satellites operate at lower altitudes—reducing signal travel time and improving data rates. These enhancements make NTNs a powerful tool for applications such as global IoT connectivity, disaster response, maritime and aeronautical communications and remote sensing.
Allied Market Research forecasts the NTN market will reach $93.6 billion by 2032 with a CAGR of 40.6%. Expect NTN-enabled LEO networks to support applications ranging from real-time environmental monitoring to direct-to-device (D2D) satellite connectivity for smartphones and wearables.
One of the critical advancements enabling NTNs is the development of 5G regenerative payloads—satellite-based base stations that process signals in orbit instead of simply routing them to a ground station. These payloads allow for greater network efficiency, lower latency and better spectrum utilization.
For NTNs to become truly viable, user terminals—whether smartphones, IoT devices or enterprise communication systems—must be adapted to support 5G NTN. Enhancements in 3GPP releases 17, 18 and 19 introduced critical upgrades, including satellite-based timing synchronization, power efficiency optimizations and signal adaptation techniques to maintain reliable communication even in high-mobility environments.
Furthermore, the adoption of millimeter wave (mmWave) spectrum (FR2), which offers higher bandwidth and throughput, can significantly enhance satellite communications. However, these frequencies also require advanced processing capabilities to manage increased data rates and mitigate interference effectively. This reinforces an even greater need for optimized power efficiency and signal processing.
As NTNs scale globally, security becomes a central concern for operators and governments alike. Satellite communications are inherently vulnerable to cyber threats, including eavesdropping, signal jamming and data interception. Future NTN deployments must incorporate advanced encryption protocols, AI-powered anomaly detection and quantum-resistant security measures to ensure safe and resilient communications.
Additionally, power efficiency remains a fundamental constraint, particularly for space-based systems with limited energy resources. Advances in semiconductor design, energy-efficient signal processing and intelligent power management solutions will be necessary to maximize the lifespan and efficiency of satellites, user terminals and ground stations. Processing-intensive tasks such as adaptive beamforming, real-time Doppler compensation and AI-driven interference mitigation must be optimized to balance performance with power consumption.
Satellite communications are undergoing a major shift as the industry moves away from proprietary technologies toward standardized 3GPP 5G NTN frameworks to enable greater interoperability, scalability and efficiency across space and terrestrial networks.
By adopting 3GPP 5G standards, NTN operators can create a unified ecosystem that allows satellite and ground-based networks to function seamlessly together. Standardization enhances service quality, expands global reach and ensures users in remote areas receive the same level of connectivity as those in urban centers.
Beyond interoperability, 3GPP 5G NTN introduces technical adaptations that improve satellite network performance. Given the long signal travel times and variable signal strengths inherent in NTN communication, 3GPP introduces enhancements such as advanced error correction, dynamic link adaptation and network slicing to ensure reliable and efficient satellite communications.
The future of satellite communication is intertwined with smart edge advancements and the evolution of 5G and 6G, which together enable more intelligent, adaptive networks that optimize connectivity in real time. In parallel, AI integration is transforming satellite constellations into distributed data centers—leveraging the low latency of LEO satellites to process data closer to users, reduce reliance on distant cloud infrastructure and offload compute demands from power-constrained edge devices.
As satellite constellations expand and NTN technology matures, truly global, high-speed, low-latency internet access is becoming a reality and a key enabler to future edge AI use cases. This shift will drive economic growth, enhance emergency response and advance digital inclusion—cementing NTNs as a fundamental pillar of modern communication infrastructure.
Satellite communications are at the forefront of the next era of global connectivity. By extending network access beyond terrestrial infrastructure, NTNs have the potential to revolutionize industries, bridge the digital divide and enhance emergency response capabilities. However, achieving this vision requires overcoming key technical, regulatory and environmental challenges through continued innovation and collaboration.
With advancements in processing technology, the adoption of 3GPP 5G NTN standards and the integration of AI-powered solutions, NTNs are rapidly becoming a necessity. As investment and development accelerate, the dream of seamless, global connectivity is no longer a distant aspiration; it is happening now. The future of communications extends beyond Earth's boundaries, creating new opportunities for people, industries and societies worldwide.

Elon Musk is not leaving Washington quietly
Elon Musk is not leaving the nation's capital quietly. The Tesla CEO confirmed his exit from Washington, D.C., in a post on X Wednesday night, saying that his scheduled time as a special government employee is coming "to an end." "I would like to thank President [Trump] for the opportunity to reduce wasteful spending," Musk wrote on X, referring to his work with the Department of Government Efficiency. The post came one day after telling CBS in an interview that is scheduled to air in full this weekend that he was "disappointed" by the price tag of Trump's "big, beautiful bill" that could produce over $3 trillion in new red ink if the bill is passed. The bill "increases the budget deficit ... and undermines the work that the DOGE team is doing," he said. White House adviser Stephen Miller said on X that the bill would in fact reduce the deficit and that DOGE cuts would have to be formalized in subsequent legislation. The world's richest man is making his views on a variety of subjects well known in Washington as he returns his attention to his many businesses, including Tesla (TSLA) and SpaceX ( He told Bloomberg last week that he is going to do less political spending in the future, saying "I think I've done enough," and acknowledged to Ars Technica that "I think I probably did spend a bit too much time on politics." His ongoing feud with OpenAI's Sam Altman even became part of the Washington conversation after the Wall Street Journal reported that Musk pushed back against a deal announced last week that has OpenAI ( and other tech giants building an AI data center in Abu Dhabi. The Wall Street Journal and the New York Times reported that Musk tried to include his AI company, xAI, in the deal, but that didn't happen. Musk also made it clear this week that he is returning to the office so he can focus on his businesses, including Tesla, SpaceX, and X. "Back to spending 24/7 at work and sleeping in conference/server/factory rooms," he said Tuesday on X, adding that he "must be super focused on X/xAI and Tesla (plus Starship launch next week), as we have critical technologies rolling out." Tesla itself is gearing up for crucial robotaxi trials in Austin, starting at the end of July. Musk and Tesla have bet the future of the company on self-driving and the ability for its cars to perform robotaxi services. Tesla's dedicated robotaxi — the Cybercab — is slated for a 2026 launch as well. And Tesla's long-awaited, more affordable EVs are expected to be revealed in the first half of the year. Musk's return to work has been teased since April, when he said his time in D.C. would be dropping. "Starting early next month, in May, my time allocation to DOGE will drop significantly," Musk told investors on Tesla's Q1 earnings call. But reports showed Musk was still spending time in D.C. in April. Last week, during two separate interviews with Bloomberg and CNBC, Musk reiterated his rededication to his companies. He also said he sees himself in the Tesla CEO chair for at least the next five years. Musk and his DOGE allies rode into Washington months ago with giant promises to cut "at least" $2 trillion from the government's annual budget, an effort that has shown little results even after causing chaos among the federal workforce and seeing Musk recently take a step back. A tracker of real-time government spending from the Brookings Institution shows that overall government spending in calendar year 2025 is actually slightly up from 2024 spending levels, even as the effects of DOGE can clearly be seen on smaller agencies like the US Agency for International Development (USAID). In an interview this week with the Washington Post, Musk lamented the criticism and opposition his cost-cutting project engendered, saying, "DOGE is just becoming the whipping boy for everything." Musk previously appeared to signal his opposition to the bill when he posted last week — as the bill was being debated — that "the profligacy of government means that only radical improvements in productivity can save our country." This week's CBS interview has seen him be much more specific. "I think a bill can be big or it can be beautiful, but I don't know if it can be both," he joked, adding, "My personal opinion." But in his post on X Wednesday night, Musk struck a note of optimism: DOGE's mission, he said, "will only strengthen over time as it becomes a way of life throughout the government."

Trump Administration Live Updates: President to Hold Oval Office News Conference With Elon Musk
Elon Musk left his government position on Wednesday, after weeks of declining influence and increasing friction with President Trump and shareholders of his own private companies. Just three months ago, Elon Musk stood before a crowd of roaring conservatives and held up a chain saw. He was at the height of his influence, swaggering in a self-designed role with immense power inside and outside the government. 'We're trying to get good things done,' he said, using the chain saw as a metaphor for the deep cuts he was making in government. 'But also, like, you know, have a good time doing it.' Mr. Musk's time in government is over now. His good time ended long before. Mr. Musk is leaving his government position after weeks of declining influence and increasing friction with both President Trump and shareholders of his own private companies. But Mr. Trump on Thursday suggested that he was still aligned with one of his chief political patrons, saying that he would appear with Mr. Musk at the White House on Friday afternoon for a news conference. 'This will be his last day, but not really, because he will always be with us, helping all the way,' Mr. Trump wrote in a post on his social media site. 'Elon is terrific!' Mr. Musk's time in Washington has brought significant benefits to his fastest-growing company, SpaceX, the rocket and satellite communications giant. Musk allies were chosen to run NASA and the Air Force — two of SpaceX's key customers — and one of the company's major regulators, the Federal Communications Commission. But Mr. Musk never came close to delivering on the core promise of his tenure: that he could cut $1 trillion from the federal budget. His Department of Government Efficiency was full of government newcomers who struggled with both the law and the facts. They posted error-filled data and made procedural mistakes undercutting their credibility. They also rushed through cuts without seeming to understand what they were cutting. On the group's website, 47 percent of the contracts they canceled are listed as saving taxpayers nothing. The group eviscerated agencies and laid off thousands of federal employees, disrupting services — and workers' livelihoods — without providing the payoff Mr. Musk promised. When he left, DOGE said it was only 18 percent of the way toward his savings goal. Mr. Musk's team also saddled the government with dozens of ongoing lawsuits, including several in which judges have paused the cuts. So just months after Mr. Musk wielded the chain saw, playing the villain in Washington's nightmare, he left claiming another role: Washington's victim. He departed complaining. 'The federal bureaucracy situation is much worse than I realized,' he told The Washington Post. 'I thought there were problems, but it sure is an uphill battle trying to improve things in D.C., to say the least.' Mr. Musk has said he is leaving because he has reached the legal limit for how long he can work as an unpaid 'special government employee.' He said in a post on X, his own social media platform, that his budget-cutting group's 'mission will only strengthen over time as it becomes a way of life throughout the government.' He did not respond to requests for comment from The New York Times. Image Elon Musk stood before a crowd of roaring conservatives and held up a chain saw during a conference in February. Credit... Eric Lee/The New York Times His departure brought another sign of his waning influence in Washington. Mr. Musk publicly bashed a bill backed by Mr. Trump that recently passed the House. Karoline Leavitt, the White House press secretary, thanked Mr. Musk for his service, but said Mr. Trump still supports the bill. 'The president is very proud of the One Big Beautiful Bill, and he wants to see it pass,' she said, referring to the legislation's name. Mr. Musk, a former ally of President Obama's who had been drifting right for years, became Mr. Trump's biggest donor during the 2024 presidential election. During the campaign, he suggested himself as head of a 'Department of Government Efficiency' — taking the name from an internet meme about a Shiba Inu. It was an example of the way Mr. Musk mixed the serious and the ridiculous during his time in power: The most fearsome force in Washington, for several months, was a small group of casually dressed young people named after a dog. Yet Mr. Musk was a highly useful ally for Mr. Trump during the 2024 campaign, and he remained so once he became an official adviser to the president. Mr. Musk's social media presence became a potential weapon against cabinet officials and administration staff members who might have voiced concern about his aggressive measures against the work force. Mr. Musk's power was clear on Feb. 26, when Mr. Trump held his first cabinet meeting. It was Mr. Musk — an unpaid employee with little formal power — who spoke before any of the cabinet secretaries. 'They will follow the orders,' Mr. Trump said. Image In the weeks following President Trump's first cabinet meeting, Mr. Musk became less of a help and more of a magnet for headlines that Mr. Trump's advisers considered damaging. Credit... Doug Mills/The New York Times But in the weeks that followed, Mr. Musk became less of a help and more of a magnet for headlines that Mr. Trump's advisers considered damaging, particularly in how he described the social safety net, such as claiming he had found 'massive' fraud in Social Security spending. Mr. Musk's budget-cutting group, despite promising transparency, was secretive. It provided one public window into its work: an online 'Wall of Receipts' that listed all the contracts, grants and leases the group had canceled. In early March, it already showed $105 billion in savings, more than one-tenth of the way to Mr. Musk's goal. 'Unless we're stopped, we will get to a trillion dollars of savings,' Mr. Musk said on Fox Business on March 10. But from the start, the site inflated what the group had achieved, and often seemed to show that DOGE did not understand the bureaucracy it was cutting. The group double-counted the same cuts, posted a claim that confused 'billion' with 'million,' and boasted about killing contracts that had been dead for years. Some claims were deleted, but the group never solved its problem with errors. More recently, the group's site has shown that Mr. Musk's frenetic cutting fell far short of its goal. On the day he left Washington, it showed his group had cut $175 billion. That may be swamped at the behest of Mr. Trump himself: House Republicans recently passed a domestic policy bill endorsed by the president that could add trillions in new debt. 'The intent and spirit of DOGE were excellent,' said Dominik Lett, a policy analyst at the libertarian Cato Institute. 'But it clearly fell far short of its goals.' The cuts did have the effect of causing fear and disruption within agencies and reducing the federal work force. It is not yet clear how many employees have been fired at the direction of DOGE. Around 20,000 probationary employees were dismissed in February. But because of legal challenges, many are still getting paid in a leave status. Tens of thousands more have left the government through voluntary departure options. Image Mr. Musk's budget-cutting group had the effect of causing fear and disruption within agencies and reducing the federal work force. Credit... Tierney L. Cross for The New York Times It is also difficult to measure the impact of another project taken on by Mr. Musk's group: accessing and centralizing huge amounts of data about average Americans, including Social Security numbers, immigration records and documents about bank accounts and employment. This information had been kept in separate databases, to limit what any government employee could learn about one person. But Mr. Musk's group sought to collect the data and merge it, alarming privacy and security experts and profoundly refashioning the way government data is used. Already, this newly assembled data seems to have been used in immigration enforcement. The Social Security Administration agreed to provide the addresses of nearly 100,000 people to Immigration and Customs Enforcement. The Internal Revenue Service's decision to provide taxpayer data to the Department of Homeland Security to help it deport immigrants prompted some longtime I.R.S. officials to resign. Some of the efforts to access and share data have been temporarily held up in court. But DOGE has won key cases that have allowed it to make real progress on a top priority of the Trump administration. Even while he led the government's budget-cutting effort, Mr. Musk also sought to shape public opinion from the outside — using his social media platform X to pressure Republicans and rally public opinion. It worked, at least at first. In December, before Mr. Trump even took office, Mr. Musk convinced House Republicans to block a spending bill. Even after Mr. Musk took on his official role, he regularly weighed in on other matters before the administration, voicing his personal frustrations with tariff policy and Mr. Trump's tax bill in a way that Mr. Trump would not tolerate from others on his staff. In April, Mr. Musk got a harsh lesson in the limits of his power. He and an allied group spent over $25 million to help the conservative candidate in a race for the Wisconsin Supreme Court — turning the race into a referendum on himself at the peak of DOGE's influence. Mr. Musk's candidate lost badly. Mr. Musk appeared chastened by the experience, signaling to others close to him that he realized his public role in the race had become a political liability. At the same time, Mr. Musk's companies began to feel the impacts of his new, polarizing political identity. Tesla sales have slumped in the United States and overseas, as backlash to Mr. Musk's politics combined with greater competition from other electric vehicle makers. In the United Kingdom, one anti-Musk poster showed a picture of the world's richest man emerging from a Tesla's roof with his hand pointing upward in a straight-armed salute. 'Goes from 0 to 1939 in 3 seconds,' the ad read, referring to the year that Britain declared war on Nazi Germany. Mr. Musk has said that his gesture, made at an event for Mr. Trump in January, was not intended to echo a Nazi salute. Image People gathered outside a Tesla dealership earlier this month in Austin to protest Mr. Musk. Credit... Desiree Rios for The New York Times Even as Mr. Musk departs, his companies still have their friends — and their business — in Washington. Sean P. Duffy, the transportation secretary, agreed at his confirmation hearing to re-examine $633,000 in safety fines against SpaceX delivered by the Biden administration. The Federal Aviation Administration, meanwhile, has continued to approve launch licenses for SpaceX, even after two recent incidents in which its newest rocket called Starship exploded over the Caribbean, forcing airplanes to divert to avoid falling debris. Asked if Mr. Musk's presence in the Trump administration has affected how the F.A.A. treats SpaceX, the agency on Thursday had a one-word response: 'No.' SpaceX, already one of the biggest NASA and Pentagon contractors, could win billions of dollars in new contracts if Mr. Trump's budget proposal is approved by Congress, particularly plans to build a new missile defense system he has called a 'Golden Dome,' and to accelerate an effort by NASA to bring astronauts to Mars. The Justice Department in February also disclosed that it was moving to dismiss a case against SpaceX, first filed in 2023, that accused the rocket company of discriminating against people based on their citizenship status. Three days before Brett Shumate, a senior Justice Department official, submitted the document to dismiss the case against SpaceX, he filed a separate legal memo on behalf of the government defending Mr. Musk's work at DOGE. 'He is an employee of the White House office,' Mr. Shumate wrote in his Feb. 17 memo to a federal court in Washington, referring to Mr. Musk. 'And he only has the ability to advise the president, or communicate the president's directives, like other senior White House officials.' Image Mr. Musk's SpaceX, already one of the biggest NASA and Pentagon contractors, could win billions of dollars in new contracts if President Trump's budget proposal is approved by Congress. Credit... Gabriel V. Cárdenas for The New York Times Another thorn in SpaceX's side was also curtailed while Mr. Musk worked in government. The Fish and Wildlife Service had two local staff members who routinely monitored SpaceX activities in South Texas. They had raised questions since testing operations started there in 2019 about harm that SpaceX had caused to an adjacent state park land and a National Wildlife Refuge, including fires from launch mishaps and damage to nests of threatened bird species. One of those wildlife biologists retired, and a second was transferred late last year to a new post. 'There is not any real oversight going on now there on a regular basis,' said Jim Chapman, a board member at SaveRGV, an environmental group in South Texas. An email sent to the spokeswoman still listed on the agency website as the regional contact bounced back, saying she no longer worked for Fish and Wildlife.

Musk's Drug Use on Campaign Trail Generated Concern, Report Says
Elon Musk was using drugs more heavily than previously known while on the campaign trail to help elect Donald Trump president, worrying some people close to the mercurial billionaire, the New York Times reported. The chief executive officer of Tesla Inc. and SpaceX traveled with a medication box that held about 20 pills and was taking so much ketamine that it was affecting his bladder, according to the report, which cited private messages and interviews with people who know or work with Musk. He also took Ecstasy and psychedelic mushrooms on occasions, the New York Times said.
