T-Mobile Sets New Uplink Speed Record with 5G Advanced
BELLEVUE, Wash.--(BUSINESS WIRE)--May 7, 2025--
While other carriers are still talking about download speed, T-Mobile (NASDAQ: TMUS) today announced a record-breaking 550 Mbps uplink speed in sub-6 GHz spectrum, which it achieved using 3GPP Release 17 UL Tx Switching in a live demo with Nokia and MediaTek. The Un-carrier just made history with the world's first live demo of R17 UL Tx Switching — not in a lab but a real commercial site in Seattle, proving once again that innovation lives at T-Mobile.
'Everyone obsesses over download speed, but at T-Mobile we see what's coming, and uplink is the next big thing,' said Ulf Ewaldsson, President of Technology, T-Mobile. 'Whether you're uploading 4K video, gaming in real time, or powering a VR headset, this record shows that T-Mobile is already building the network for that future and focused on bringing the best customer experience.'
T-Mobile achieved this record-breaking 5G Advanced uplink speed by implementing the 3GPP Release 17 UL Tx Switching feature. This feature provides smart multiplexing to maximize user throughput on the available device Tx chains by optimizing use of UL Carrier Aggregation and UL MIMO for TDD and FDD spectrum.
'It's significantly more challenging for carriers to enhance data speeds in the uplink — from a mobile device back to the network — compared to boosting downlink speeds. This is precisely what makes this achievement so impressive. As demand continues to rise for AI, XR and video uploads, exceptional uplink performance will become essential,' said Tommi Uitto, President of Mobile Networks at Nokia. 'Our partnership with T-Mobile keeps growing stronger, fueling innovation, shaping the network of the future and delivering extraordinary experiences to T-Mobile's customers.'
Uplink Speed in Action
In the T-Mobile live network demonstration, 100MHz of TDD spectrum (n41) and 35MHz of FDD spectrum (n25) was used to achieve the record breaking 550 Mbps total speed. The test was conducted using a MediaTek smartphone flagship test device with an integrated M90 modem.
'This groundbreaking 550 Mbps uplink speed achievement, using 5G Advanced features, is a thrilling example of the innovation that can take place when we work together,' said HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek. 'This milestone, a result of collaboration with T-Mobile, marks a significant leap forward for immersive VR and AR experiences, enabling creators and consumers to seamlessly interact, stream and share content with unparalleled real-time responsiveness.'
The Leader in 5G
T-Mobile has consistently led the charge in uplink innovation, setting a record of 275 Mbps in 2022, breaking it with 345 Mbps in early 2024 using Release 16 UL Tx Switching and this year, surpassing 500 Mbps with Release 17. This is just the beginning — as 5G Advanced evolves, so will the Un-carrier's lead.
This demo highlights T-Mobile's ongoing commitment to bringing customers the best in 5G Advanced , now available nationwide. With this record-breaking uplink speed, T-Mobile isn't just ahead of the pack in 5G; it's shaping what's next, always focused on giving customers the experience they deserve.

Musk Follows Harvard In Biting The Hand That Feeds
Elon Musk and Harvard Both Bite the Governmental Hand that Feeds Them From an early age, children are taught essential lessons: do not play with fire, do not pet strange dogs, and if one cannot swim, stay out of the deep end. Another timeless rule—often forgotten by those in positions of immense wealth and influence—is this: do not bite the hand that feeds you. This lesson, while simple, has profound implications in the real world. It applies just as readily to billionaires and institutions as it does to children on a playground. Yet recent actions by both Elon Musk and prominent academic institutions—most notably Harvard, but also Columbia, MIT, and others—suggest that even the most successful individuals and organizations are capable of ignoring foundational wisdom. Harvard set the tone. Amid growing political scrutiny and a shifting cultural landscape, the university has drawn intense criticism over its handling of campus protests, particularly those involving slogans such as 'from the river to the sea.' The administration's decision to defend even the most controversial speech—widely viewed by many as antisemitic—has triggered investigations and jeopardized billions in tax-exempt status and government research funding. This raises a critical question: is this truly the hill worth dying on? Is preserving the right to controversial protest slogans worth risking Harvard's institutional future? It is doubtful that most students and faculty would knowingly trade funding, grants, and prestige for this fight. Elon Musk, the world's richest man, has now followed suit—this time turning his attention toward President Donald Trump, with whom he has launched a high-profile and personal feud. What makes this move especially striking is that President Trump is not a distant figure or a fading influence. He is once again sitting in the White House, wielding executive authority over regulatory agencies, defense contracting, and infrastructure initiatives—all areas that directly affect Musk's companies. Tesla, SpaceX, and xAI have flourished in part because of government partnership. SpaceX alone holds multibillion-dollar contracts with NASA and the Department of Defense. Tesla has benefitted from years of energy subsidies and EV tax incentives. Picking a fight with the sitting president—regardless of personal conviction—puts this entire ecosystem at risk. And again the question must be asked: is this battle worth the damage? Whatever principle Musk may be defending, the consequences extend far beyond himself. Shareholders, employees, and retail investors—many of whom placed their trust and savings in his leadership—are the ones left exposed. The parallel between Harvard and Musk is striking: both have been immensely successful, aided in large part by government funding, favorable regulation, and public goodwill. And both have, for different reasons, chosen to confront the very institutions and leaders that have helped sustain their growth. There is precedent for how this ends. Jack Ma, once the most powerful entrepreneur in China, famously criticized the Chinese government. The backlash was immediate and absolute. His companies were dismantled. His IPO was cancelled. His wealth and influence evaporated almost overnight. Even in less authoritarian systems, the lesson holds: those who antagonize the systems that support them may not survive the consequences. While Musk's personal net worth has dropped from nearly $450 billion to approximately $300 billion, the impact is more symbolic than practical for him. But for millions of investors, employees, and stakeholders, these battles matter. Market volatility, regulatory backlash, and reputational risk all come with tangible financial costs—costs borne not just by Musk himself, but by those who have trusted and invested in his vision. The same applies to Harvard and peer institutions. Their leadership may believe they are standing on principle, but the price of alienating government agencies and key financial backers could reshape the long-term trajectory of these universities. The erosion of public trust, the loss of bipartisan support, and the potential withdrawal of federal funding pose existential threats. Leadership—whether in business or academia—requires more than conviction. It requires judgment, timing, and the discipline to separate personal ideology from institutional responsibility. Founder-led companies often outperform when leaders are focused, visionary, and measured. But when ego replaces strategy, the consequences can be swift and severe. No one is demanding absolute political alignment or silence in the face of controversy. No one is asking Elon Musk to wear a MAGA hat. But his recent actions have been so volatile, so self-destructive, that investors may soon be tempted to hand him something else entirely—a MEGA hat: Make Elon Great Again. In today's polarized environment, the margin for error has narrowed. And for those who owe much of their success to public support—whether in Silicon Valley or the Ivy League—biting the hand that feeds is not just unwise. It is unsustainable. ---------------------------------- Disclosure: Past performance is no guarantee of future results.

An AI Film Festival And The Multiverse Engine
In the glassy confines of Alice Tully Hall on Thursday, the third annual Runway AI Film Festival celebrated an entirely new art form. The winning film, Total Pixel Space, was not made in the traditional sense. It was conjured by Jacob Adler, a composer and educator from Arizona State University, stitched together from image generators, synthetic voices, and video animation tools — most notably Runway's Gen-3, the company's text-to-video model (Runway Gen-4 was released in March). Video generation technology emerged in public in 2022 with Meta's crude video of a flying Corgi wearing a red cape and sunglasses. Since then, it has fundamentally transformed filmmaking, dramatically lowering barriers to entry and enabling new forms of creative expression. Independent creators and established filmmakers alike now have access to powerful AI tools such as Runway that can generate realistic video scenes, animate storyboards, and even produce entire short films from simple text prompts or reference images. As a result, production costs and timelines are shrinking, making it possible for filmmakers with limited resources to achieve professional-quality results and bring ambitious visions to life. The democratization of content creation is expanding far beyond traditional studio constraints, empowering anyone with patience and a rich imagination. Adler's inspiration came from Jorge Luis Borges' celebrated short story The Library of Babel, which imagines a universe where every conceivable book exists in an endless repository. Adler found a parallel in the capabilities of modern generative machine learning models, which can produce an unfathomable variety of images from noise (random variations in pixel values much like the 'snow' on an old television set) and text prompts. 'How many images can possibly exist,' the dreamy narrator begins as fantastical AI-generated video plays on the screen: a floating, exploding building; a human-sized housecat curled on a woman's lap. 'What lies in the space between order and chaos?' Adler's brilliant script is a fascinating thought experiment that attempts to calculate the total number of possible images, unfurling the endless possibilities of the AI-aided human imagination. 'Pixels are the building blocks of digital images, tiny tiles forming a mosaic,' continues the voice, which was generated using ElevenLabs. 'Each pixel is defined by numbers representing color and position. Therefore, any digital image can be represented as a sequence of numbers,' the narration continues, the voice itself a sequence of numbers that describe air pressure changes over time. 'Therefore, every photograph that could ever be taken exists as coordinates. Every frame of every possible film exists as coordinates.' Winners at the 3rd Annual International AIFF 2025 Runway was founded in 2018 by Cristóbal Valenzuela, Alejandro Matamala, and Anastasis Germanidis, after they met at New York University Tisch School of the Arts. Valenzuela, who serves as CEO, says he fell in love with neural networks in 2015, and couldn't stop thinking about how they might be used by people who create. Today, it's a multi-million-user platform, used by filmmakers, musicians, advertisers, and artists, and has been joined by other platforms, including OpenAI's Sora, and Google's Veo 3. What separates Runway from many of its competitors is that it builds from scratch. Its research team — which comprises most of the company — develops its own models, which can now generate up to about 20 seconds of video. The result, as seen in the works submitted to the AI Film Festival, is what Valenzuela calls 'a new kind of media.' The word film may soon no longer apply. Nor, perhaps, will filmmaker. 'The Tisches of tomorrow will teach something that doesn't yet have a name,' he said during opening remarks at the festival. Indeed, Adler is not a filmmaker by training, but a classically trained composer, a pipe organist, and a theorist of microtonality. 'The process of composing music and editing film,' he told me, 'are both about orchestrating change through time.' He used the image generation platform Midjourney to generate thousands of images, then used Runway to animate them. He used ElevenLabs to synthesize the narrator's voice. The script he wrote himself, drawing from the ideas of Borges, combinatorics, and the sheer mind-bending number of possible images that can exist at a given resolution. He edited it all together in DaVinci Resolve. The result? A ten-minute film that feels as philosophical as it is visual. It's tempting to frame all this as the next step in a long evolution; from the Lumière brothers to CGI, from Technicolor to TikTok. But what we're witnessing isn't a continuation. It's a rupture. 'Artists used to be gatekept by cameras, studios, budgets,' Valenzuela said. 'Now, a kid with a thought can press a button and generate a dream.' At the Runway Film Festival, the lights dimmed, and the films came in waves of animated hallucinations, synthetic voices, and impossible perspectives. Some were rough. Some were polished. All were unlike anything seen before. This isn't about replacing filmmakers. It's about unleashing them. 'When photography first came around — actually, when daguerreotypes were first invented — people just didn't have the word to describe it,' Valenzuela said during his opening remarks at the festival. 'They used this idea of a mirror with a memory because they'd never seen anything like that. … I think that's pretty close to where we are right now.' Valenzuela was invoking Oliver Wendell Holmes Sr.'s phrase to convey how photography could capture and preserve images of reality, allowing those images to be revisited and remembered long after the moment had passed. Just as photography once astonished and unsettled, generative media now invites a similar rethinking of what creativity means. When you see it — when you watch Jacob Adler's film unfold — it's hard not to feel that the mirror is starting to show us something deeper. AI video generation is a kind of multiverse engine, enabling creators to explore and visualize an endless spectrum of alternate realities, all within the digital realm. 'Evolution itself becomes not a process of creation, but of discovery,' his film concludes. 'Each possible path of life's development … is but one thread in a colossal tapestry of possibility.'
