London’s Tube network extends 4G/5G connectivity | Computer Weekly


One of the places in the UK capital where mobile connectivity is strongest is up to 30m underground, as more stations and tunnelled sections of the Tube network across London now have 4G and 5G mobile coverage as part of the ongoing development project between Transport for London (TfL) and Boldyn Networks.

TfL carries up to four million passengers a day on the London Underground network, and renewing and preparing the communications network for the future has long been regarded as essential to maintain and improve critical infrastructure. Before it carried out its first expansion work, TfL noted that legacy systems can slowly become unreliable and disrupt services, leading to delays and an overall negative impact on passenger journeys.

All of the three mobile network operators – VodafoneThree, EE and Virgin Media O2  – are taking part in the roll-out, as part of the Mayor of London’s and TfL’s stated commitment to bring mobile connectivity to the whole of London’s transport network.

The expanding coverage will host the new Emergency Services Network (ESN) which, when fully operational, is designed to give first responders immediate access to life-saving data, images and information in live situations and emergencies on the frontline.

Boldyn Networks was awarded a 20-year concession by TfL in June 2021 to deliver high-speed mobile connectivity across the entire London Underground network, creating a backbone of mobile and digital connectivity across the network to all ticket halls, platforms and tunnels on the Tube network, with total network coverage targeted for some time in 2026.

Around 400 engineers are regularly working on the project overnight, delivering the project during the limited overnight engineering hours on the Tube network. Boldyn is also committed to installing a fibre backbone across the capital to improve connectivity both above and below ground.

TfL and Boldyn are working to introduce high-speed 4G and 5G mobile coverage across the whole Tube, Docklands Light Railway (DLR), Elizabeth line network, and the Windrush line between Highbury & Islington and New Cross. Following full interoperability testing being completed across all Tube lines in 2025, design and initial testing work is now underway on the Windrush line and DLR, ahead of the tunnelled sections and stations getting coverage later in 2026.

Alongside the whole of the Elizabeth line, which was completed in December 2024, 62 out of 121 Tube stations which are located “underground” now have begun receiving mobile coverage in their ticket halls, corridors and platforms. Key stations including Euston Square, Cannon Street and Battersea Power Station have recently gone live with 4G and 5G mobile coverage, with more – including King’s Cross St Pancras, Gloucester Road, Warwick Avenue and Vauxhall – set to go live in the next few months.

TfL also revealed that work to extend coverage in the tunnels along Tube lines was continuing to “make good progress”, with the first sections of the Circle and District line between Blackfriars and Cannon Street, and between Notting Hill Gate and Bayswater, now live. TfL and Boldyn are working to introduce more sections as quickly as possible during 2026 and they expect “the vast majority” of the Northern and Metropolitan lines to have coverage in the tunnels by end of summer 2026.

Work to deliver mobile coverage across the whole Tube network will continue throughout 2026, with work focusing on sections of the Circle and District line, where a number of stations already have limited mobile coverage due to being closer to the surface, as well as along the Victoria, Jubilee, Bakerloo and Piccadilly lines. Installation work will also continue along sections outside of Central London, and where smaller tunnelled sections need to be treated individually.

Installation work is already taking place alongside the planned escalator works at Cutty Sark Docklands Light Railway station to help ensure that customers can benefit from mobile coverage at this station as quickly as possible.

Alongside installing mobile coverage across the Tube, TfL and Boldyn are also working to install small-cell mobile technology on TfL assets, such as lighting columns, to enhance mobile connectivity in high-footfall urban areas. Some of the capital’s busiest areas such as King’s Cross, Waterloo, London Bridge, Old Street, The Shard and Hyde Park Corner already have such connectivity.

Commenting on the network and the aims of the project as a whole, Isabel Coman, director of engineering and asset strategy at TfL, said: “It’s great to see further progress in our goal to introduce high-speed mobile coverage across our Tube network…We are on a clear path towards having 4G and 5G mobile coverage across the whole network by the end of 2026. Engineers are working hard overnight during the limited engineering hours to deliver this programme.”

Boldyn Networks UK & Ireland chief operating officer Nick Hudson added: “Our long-term partnership with TfL to extend reliable 4G and 5G mobile coverage across the London Underground is grounded in improving everyday journeys for millions of people. A project of this scale demands extraordinary engineering effort and close-knit collaboration with TfL, with work often carried out overnight in one of the world’s most complex transport networks.

“We’re immensely proud of what’s been achieved so far, and each section completed brings us closer to our goal of creating a more connected London for those who visit the city and those who call it home.”

Tackling the housing shortage with robotic microfactories

Tackling the housing shortage with robotic microfactories



A national housing shortage is straining finances and communities across the United States. In Massachusetts, at least 222,000 homes will have to be built in the next 10 years to meet the population’s needs. At the same time, there are numerous challenges in traditional construction. There’s a shortage of skilled construction workers. Most projects involve multiple contractors and subcontractors, adding complexity and lag time. And the construction process, as well as the buildings themselves, can be a major source of emissions that contribute to climate change.

Reframe Systems, co-founded by Vikas Enti SM ’20, uses robotics, software, and high-performance materials to address these problems. Founded in 2022, the company deploys microfactories that bring housing fabrication and production closer to the regions where the homes are needed. The first homes designed and manufactured in Reframe’s first microfactory have been fully built in Arlington and Somerville, Massachusetts. 

Enti’s experiences in MIT System Design and Management (SDM) shaped the company from its start. “Learning how to navigate the system and finding the optimal value for each stakeholder has been a key part of the business strategy,” he says, “and that’s rooted in what I learned at SDM.”

Better tools for system-level problems

Enti applied to SDM’s master of science in engineering and management while he was working at Kiva Systems, overseeing its acquisition by Amazon and transformation into Amazon Robotics. He found that the SDM program’s fundamentals of systems engineering, system architecture, and project management provided him with the tools he needed to address system-level problems in his work.

While he was at MIT, Enti also served as an associate director for the MIT $100K Entrepreneurship Competition, which offers students and researchers mentorship, feedback, and potential funding for their startup ideas. He realized that “there isn’t a single formula for how businesses start, or how long it takes to get them started,” he says, which helped shape his plans to start his own business.

Enti took a leave of absence from MIT to oversee the expansion of Amazon Robotics in Europe. He returned and completed his degree in 2020, writing his thesis on developing technology that could mitigate falls for elderly people. This instinct to use his education for a good cause resurfaced when his daughters were born. He wanted his future business to address a real-world problem and have a social impact, while also reducing carbon emissions.

Growing housing, shrinking emissions

Enti concluded that housing, with immediate real-world impact and a significant share of global carbon emissions, was the right problem to work on. He reached out to his colleagues Aaron Small and Felipe Polido from Amazon Robotics to share his idea for advanced, low-cost factories that could be deployed quickly and close to where they were needed. The two joined him as co-founders.

Currently, the microfactory in Andover, Massachusetts, produces structural panels, with robotics completing wall and ceiling framing and people completing the rest of the work, including wiring and plumbing. Eventually, Reframe hopes to automate more of the building process through further use of robotics. The modular construction process allows for reduced waste and disruption on the eventual home site. And the finished homes are designed to be energy-efficient and ready for solar panel installation. The company is set to start work soon on a group of homes in Devens, Massachusetts.

In addition to the Andover location, Reframe is setting up in southern California to help rebuild homes that were destroyed in the area’s January 2025 wildfires. The company’s software-assisted design process and the adjustability of the microfactories allows them to meet local zoning and building codes and align with the local architectural aesthetic. This means that in Somerville, Reframe’s completed buildings look like modernized versions of the neighboring three-story buildings, known locally as “triple-deckers.” On the other side of the country, Reframe’s design offerings include Spanish-style and craftsman homes.

“Housing is a complex systems problem,” Enti says, explaining the impact SDM has had on his work at Reframe. The methods and tools taught in the integrated core class EM.412 (Foundations of System Design and Management) help him tackle systems-level problems and take the needs of multiple stakeholders into account. The Reframe team used technology roadmapping as they devised their overall business plan, inspired by the work of Olivier de Weck, associate head of the MIT Department of Aeronautics and Astronautics. And lectures on project management from Bryan Moser, SDM’s academic director, remain relevant. 

“Embracing the fact that this is a systems problem, and learning how to navigate the system and the stakeholders to make sure we’re finding the optimal value, has been a key part of the business strategy,” Enti says.

Reframe Systems is set to continue learning through iteration as they plan to expand their network of microfactories. The company remains committed to the core vision of sustainably meeting the country’s need for more housing. “I’m grateful we get to do this,” Enti says. “Once you strip away all the robotics, the advanced algorithms, and the factories, these are high-quality, healthy homes that families get to live in and grow.”

Framework Has a Better, More Take-Apart-Able Laptop


Framework, the company that makes laptops designed for optimal repairability, announced a new version of its main product, a 13-inch screen laptop. It’s called the Framework Laptop 13 Pro, and it has far better battery life, a touchscreen, a haptic touchpad, and is fitted with Intel processors.

At an event in San Francisco today, Framework CEO Nirav Patel showed off the company’s new tech, opening with a joke about making Framework AI—something the company is very much not doing. Framework’s whole thing, after all, is aiming to give users control over the physical tech they use.

“That industry is fighting for you to own nothing, and they own everything,” Patel said about the AI industry. “We’re fighting for a future where you can own everything and be free.”

Framework used the event to detail other updates coming to its 16-inch laptop. It also showed off previews of an official developer kit and a wireless keyboard for controlling your rig from the couch.

As the name implies, the 13 Pro is a step up from the company’s last version, the Framework 13. It’s also pricier, starting at $1,199 for a DIY Edition that requires assembling the computer yourself. Pre-built units start at $1,499 but can be upgraded with more features. Framework says it will start shipping the 13 Pro in June.

Framework’s signature move for its products is the ability to take the thing apart. The 13 Pro is made with that ethos in mind, so its parts can be easily swapped out, upgraded, or replaced. Four Thunderbolt 4 interfaces let you pick which ports (USB-C, HDMI, etc.) you want and then choose where to place them. Framework says it planned the laptop with cross-generation compatibility in mind, so current Framebook 13 laptop owners will be able to use new 13 Pro parts like the mainboard, display, and battery, and put them into their existing machine.

The big changes in the guts of the 13 Pro come from Framework’s shift away from using an AMD processor to Intel’s Core Ultra Series 3 processors, which Framework described in its press release as “just insanely efficient.” That efficiency, along with a bigger battery, translates to more than 20 hours of battery life while streaming 4K Netflix videos, at least that’s the claim. That’s almost 12 hours longer than the Framework 13.

OpenAI Beefs Up ChatGPT’s Image Generation Model

OpenAI Beefs Up ChatGPT’s Image Generation Model


OpenAI launched a new image generation AI model on Tuesday, dubbed ChatGPT Images 2.0. This model can generate more than one image from a single prompt, like an entire study booklet, as well as output text, including in non-English languages, like Chinese and Hindi. This release is available globally for ChatGPT and Codex users, with a more powerful version available for paying subscribers.

When any major AI company releases a new image model, it can revive interest and boost usage, especially if social media users adopt a meme-able trend, transforming images of themselves. Last year, Google’s launch of the Nano Banana model was a major moment for the company, especially when users started posting hyperrealistic figurines of themselves online. Earlier this year, ChatGPT Images made waves on social media as users shared AI-generated caricatures.

What’s Different?

Since the new model can tap into ChatGPT’s “reasoning” capabilities, Images 2.0 can search the internet for recent information and generate more than one image at a time. In essence, the bot can use additional steps to output more thorough generations from a single prompt. Images 2.0 also has a more recent knowledge cutoff date: December 2025.

This also means that outputs from the new model are more granular. For example, I generated an infographic with San Francisco’s weather forecast for the next day, as well as activities worth doing. The image ChatGPT generated included accurate weather details for the rainy day, along with accurate-looking drawings of the Ferry Building, Castro Theater, Painted Ladies houses, and Transamerica Pyramid.

Additionally, Images 2.0 is more customizable for users who want unique aspect ratios for image outputs. The new model can generate images, ranging from 3:1 wide to 1:3 tall, and users can adjust the image’s size as part of their prompt to the AI tool.

First Impressions

After a few hours of generating images with the new model, I was generally impressed with the text rendering capabilities, in English at least. Not that long ago, image outputs featuring text, from any of the major models, often included numerous malformed characters or words with errant extra letters. ChatGPT struggled to label images accurately two years prior, so the cleaner, more complex outputs from Images 2.0 are a sign of continued improvement. Google has also focused on improving image outputs featuring text in its recent iterations of Nano Banana.
