O2 UK and Cellnex Deal to Tackle 5G Mobile Not-Spots on Brighton Main Line | ISPreview UK

Original article ISPreview UK:Read More

Mobile operator O2 (Virgin Media) and wireless infrastructure firm Cellnex UK have today signed a 5-year agreement to join the Brighton Main Line (BML) connectivity project, which aims to expand “highspeed5G mobile (mobile broadband) connectivity and tackle mobile signal “not-spots” across the route.

The BML is a 108km long railway corridor in southern England that links London (Victoria and London Bridge) to Brighton on the south coast and handles 300,000 daily passengers (1,700 daily train movements). The route includes major commuter stations like London Bridge, London Victoria and Clapham Junction, as well as connecting into Gatwick Airport. The train operators on this line include Thameslink, Southern, Gatwick Express, Great Western Railway and London Overground Services.

NOTE: The Government’s 10 Year Industrial Strategy last year pledged £41m to help introduce Low Earth Orbit (LEO) broadband satellite connectivity “on all mainline trains” in order to tackle the issue of poor onboard connectivity. Meanwhile, Project Reach is separately working to deploy “ultra fast fibre optic cable” across 1,000km of major rail lines to help “eliminate mobile signal blackspots” in tunnels on “key rail routes”.

Under the plan, O2 will gain access to Cellnex UK’s purpose-built neutral host infrastructure, enabling the phased rollout of high-speed mobile connectivity, including 5G, to customers across the entire route over the “coming months“. The move follows Cellnex signing Three UK in 2023.

New indoor coverage solutions are now being deployed to enhance mobile phone connections in three of the most important London stations, London Victoria, London Bridge, and Clapham Junction, which account for roughly 19% of railway passenger traffic to and from the capital from outside London.

Steve Cray, Managing Director of Cellnex UK, said:

“Regular railway passengers will understand the frustration of losing signal mid-conversation or spending whole journeys with buffering videos. With O2 now on board, many more passengers are going to notice the difference on one of the UK’s most important commuter routes. This collaboration stands as one of the most significant end-to-end telecommunications infrastructure deployments in British railway so far, and we are proud to be setting a new standard for the UK’s entire rail network.”

Professor Robert Joyce, Director of Mobile Access Engineering at O2, said:

“Our £700m Mobile Transformation Plan is focused on delivering reliable connectivity in the moments that matter most, and railway lines are a key part of that. By working with Cellnex to improve connectivity along the Brighton Main Line, we’ll be bringing improved coverage and capacity to customers travelling from the coast to the capital over the coming months.”

Cellnex designed, planned, and built this infrastructure in partnership with Network Rail under a 25-year contract awarded in 2021, enabling all UK mobile network operators (MNOs) to access shared connectivity. As above, Three UK customers (VodafoneThree) can already access this and O2 will now join them, with related coverage improvements being brought live in stages across the route.

Once fully activated, the shared infrastructure is expected to deliver “high speed connectivity” across 99% of the 108 km route, “drastically reducing historical not-spots and ensuring passengers enjoy reliable calls, uninterrupted streaming and stable app performance” throughout their journey. The goal is to bring “seamless connectivity” to a route long challenged by deep cuttings, long tunnels and Victorian-era station infrastructure.

Spusu UK Gifts 5GB of Free Mobile Data to Celebrate Third Birthday | ISPreview UK

Original article ISPreview UK:Read More

The SIM-Only mobile operator Spusu, which holds a virtual operator (MVNO) agreement to harness EE’s 4G and 5G (mobile broadband) network, has today celebrated their third birthday since launch in the UK by gifting existing customers an extra 5GB (GigaBytes) of data for free until 30th June 2026.

Since entering the UK market in 2023, spusu has grown from a new entrant in a heavily populated industry, to a provider trusted by more than 150,000 customers. The new offer is intended to celebrate that and will be expressed in an automated customer text message, being sent out today.

The message will contain instructions on how to claim the 5GB of complimentary data. The offer is available to all customers, except those currently on an unlimited data plan, for obvious reasons. To redeem, customers just need to respond to the automated anniversary text from spusu and the data will then be automatically added to customers’ plans.

Christian Banhans, UK MD at spusu, said:

“Three years ago, spusu entered the UK market with a goal to offer a fairer alternative to complicated mobile contracts and hidden costs. While we’ve grown significantly since 2023, what matters most is that we’ve remained true to the values that brought us to the UK market in the first place – transparency, affordability and exceptional customer service.

The trust and loyalty from our customers have been instrumental to our success. This 5GB giveaway is our way of saying thank you. As we enter our fourth year in the UK, our focus remains on delivering straightforward, great-value mobile services backed by the personal customer support that has helped us build lasting relationships with customers across the country.”

Survey Claims 1 in 5 UK Sports Fans Suffered Buffering and Freezing During Live Events | ISPreview UK

Original article ISPreview UK:Read More

A new survey of 2,000 British adults, which was commissioned by broadband ISP Zen Internet (vested interest), has claimed that one in five UK sports fans have missed key moments due to buffering and freezing while watching live sport at home, while almost half (47%) have experienced some other form of internet-related problem while watching.

The survey found that, in terms of those other connectivity issues that can occur, some 14.2% have had their internet slow down because multiple devices were connected, while 12.8% have experienced delays compared with live TV or social media updates (streaming lag vs terrestrial live TV is par for the course), 12.7% have had streaming apps crash or fail to load and 11.6% have suffered poor picture quality or lag.

Suffice to say that the reliability of home broadband connectivity is “becoming a growing concern for sports fans“, particularly during live events like the FIFA World Cup 2026. Zen’s survey also found that around seven in ten respondents intend to watch at least some of the 2026 FIFA World Cup, compared to 52% who said the same ahead of the 2022 tournament.

In addition, around 13-14% will be heading to a pub or public screening to view the live action. Of those watching matches at home, almost half will rely on the internet and 14% will be checking their internet connection before kick-off.

The good news is that most modern home broadband connections should be significantly better at handling live-streaming than those that came before, particularly if you’re on a full fibre (FTTP) line. The catch is that problems can still occur within your home devices, network setup (e.g. weak Wi-Fi signals) and via the remote streaming service itself (inc. content delivery partners, routing/peering arrangements etc.), which might also suffer unexpected hiccups.

As for the issue of broadcast lag between live streams and live terrestrial TV, there are ways to reduce that delay (example), but the inherent nature of streamed content means that some lag is often inevitable when streaming.

17 Primary Schools in Blaenau Gwent to Get Gigabit Broadband Upgrade | ISPreview UK

Original article ISPreview UK:Read More

The Welsh Government’s (WG) Tech Valleys programme has announced that 17 primary schools in Blaenau Gwent to be upgraded to gigabit-speed internet as part of their new partnership with Blaenau Gwent County Borough Council and the Shared Resource Service.

The new service for the Blaenau Gwent region, which is said to be “up to ten times faster than some of the current connections” used by the schools (listed at the bottom of this article), is being funded by the WG and should deliver more reliable use of digital whiteboards, video conferencing, online learning platforms and resource-heavy applications all at once.

Many of the schools are said to have already received the upgrade, with full completion expected in time for the start of the new school year in September 2026.

Adam Price MS, Minister for Enterprise, Connectivity and Energy, said:

“This investment builds on the solid foundations already laid through the Public Sector Broadband Aggregation programme, taking the existing fibre network in these schools and unlocking its full potential with gigabit-speed capability.

The difference this makes in the classroom is real and immediate. Lessons are more dynamic, engaging and better equipped to develop the digital skills that young people will need throughout their lives and careers.”

Rural Broadband Network Quickline Launch Business Support Programme | ISPreview UK

Original article ISPreview UK:Read More

Rural UK broadband ISP Quickline, which is building a new full fibre (FTTP) and fixed wireless (FWA) network across parts of Yorkshire and Lincolnshire, have today announced that they’ve teamed-up with Enterprise Cube CIC to launch a new business support programme for start-up and early-stage companies across North Yorkshire.

The programme – called ‘Better Business‘ and forming part of the provider’s social value commitment under their Project Gigabit broadband roll-out contracts – will offer free “expert-led” workshops, practical training, tools and peer-to-peer learning for entrepreneurs who want to move from ‘starting up’ to building sustainable, resilient businesses.

NOTE: Quickline is funded by c.£500m from Northleaf Capital Partners, as well as c.£300m of public subsidy from four Project Gigabit contracts (here, here and here), plus c.£225m in term loans and debt guarantees from the National Wealth Fund and a £25m term loan from NatWest.

The goal is to help local founders turn Quickline’s new full fibre network into growth by building the skills, confidence and networks needed to grow.

The Better Business programme offers:

• Expert-led workshops covering core business essentials (including strategy, marketing, finance and operations)

• Practical tools and templates founders can use immediately

• Peer-to-peer learning with other local business owners

• Guidance to help entrepreneurs build confidence and create a plan for sustainable growth.

The programme is already said to be supporting a wide range of businesses across the region – from creative retail and community studios to specialist e-commerce.

Amelia Williamson, Social Value Lead for Quickline in North Yorkshire, said:

“At Quickline, our mission is about more than delivering fast, reliable broadband. Through Project Gigabit, we’re committed to creating meaningful social value in the communities we serve.

Better Business is helping local entrepreneurs access the skills, support and networks they need to grow, so the benefits of connectivity are felt in everyday lives and local economies.”

Richard Lanning, Co-Founder of Enterprise Cube CIC, added:

“Rural founders often have great ideas but fewer opportunities to access tailored advice and a strong peer network. Better Business brings people together with practical, hands-on support, helping entrepreneurs build momentum and stay rooted in their communities as they grow.”

At the end of 2025 Quickline’s full fibre broadband network covered 200,000 premises (excluding fixed wireless coverage, which also covers c.200,000 premises – not all gigabit-capable) – mostly across rural parts of Yorkshire and Lincolnshire. The operator currently aims to extend gigabit-capable broadband to a further 360,000 UK premises.

Broadband ISP Exascale Nears Completion of 288-Core Fibre Spine in Telford | ISPreview UK

Original article ISPreview UK:Read More

Internet provider and UK network builder Exascale, which have already deployed their own gigabit speed full fibre (FTTP) network to a few thousand premises in the Telford and Wrekin area (Shropshire), has today revealed that they’ve almost completed the build of a new high-capacity 288-core fibre spine cable across Telford.

The project, which is expected to be completed “within the coming week” and forms part of the provider’s strategy to expand their independently owned telecommunications infrastructure – across Shropshire and the wider West Midlands, should provide substantial additional capacity and resilience across their network for customers.

The new fibre route originates in the business-dense Hortonwood area, before traversing Trench Lock, Wellington, Ketley, Lawley, Horsehay and Madeley – ultimately terminating at Halesfield.

Thomas Bibb, CEO of Exascale, said:

“This investment further reinforces our commitment to building high-quality digital infrastructure for the communities and businesses we serve. By increasing both network capacity and resilience, we are ensuring that our platform is ready to support future demand while continuing to deliver the high-performance connectivity our customers expect.”

The entire project has been funded directly by Exascale without reliance on public subsidies, government grants or taxpayer funding.

Government Confirms UK Internet Social Media BAN for Children Under 16 | ISPreview UK

Original article ISPreview UK:Read More

The Prime Minister of the UK Government, Sir Keir Starmer, has today confirmed that they will introduce an internet Social Media Ban for children under the age of 16 against ten popular platforms (TikTok, Snapchat, Instagram, YouTube, Reddit, Twitch, X, Threads, Facebook and Kick). But that’s not the only restriction they’ll be introducing.

Just to recap. The recently passed Children’s Wellbeing and Schools Act 2026 (CWSA) had effectively already handed the government the legal powers to introduce new mass Social Media censorship measures, although the exact approach was due to be decided by a consultation (here).

NOTE: The Growing Up in an Online World consultation, which closed on 26th May 2026, attracted responses from more than 116,000 people across the UK – this included over 14,000 young people aged 10-21 and over 54,000 parents.

According to the Government, some 9 in 10 parents who responded to the Growing Up in an Online World parents’ consultation back a minimum age of 16 before platforms can offer their services to children. Parents also made clear they want restrictions on certain features children use every day – from stranger contact to explicit image sharing. Finally, three quarters said families would face fewer disagreements if social media was restricted.

Young people were also found to echo these concerns – some 62% who responded to the consultation said restricting the high-risk features would make them safer online. They also raised concerns about addictive design with 52% saying they wanted infinite scrolling restricted. However, children and young people are clear-eyed about the challenges too, with 72% being worried about feeling left out if restrictions came in.

The government’s decision

In response to the above, and wider political pressures, the Government has confirmed that they now intend to “go further” than the Australian model, which also recently banned social media access for under 16s.

Key Changes – UK Social Media Ban

➤ Under-16s to be banned from using ten popular platforms (i.e. existing accounts to be suspended and no new accounts allowed) – TikTok, Snapchat, Instagram, YouTube, Reddit, Twitch, X, Threads, Facebook and Kick.

➤ The government said they would be looking in more detail at overnight social media curfews and breaks in infinite scrolling for under-18-year-olds – they will set out more detail in July 2026.

➤ Restrictions on access and use of AI chatbots are to be introduced. So-called AI ‘romantic companion’ chatbots – designed to simulate sexual relationships or roleplay with users – will, for example, have to enforce a minimum age of 18. Similar intimate functionalities will be restricted for under-18s on AI chatbots more widely.

➤ Children will be stopped from being able to livestream and from chatting with strangers using online gaming apps – “these restrictions – which together with the ban go further than any other country – will apply to a wider range of online services, including on gaming sites.”

➤ Restrictions on these functionalities will also be on by default for under 16- and 17-year-olds to prevent a cliff-edge at 16.

➤ Messaging services like WhatsApp and Signal are NOT intended to be included in the social media ban.

➤ The Gov said they will “learn the lessons from Australia’s experience” by introducing more highly effective age assurance (HEAA) measures to support compliance, making it far harder for children to bypass safeguards. Ofcom will first need to conduct a rapid study on what is HEAA for verifying whether someone is over 16 (doing this in an accurate, privacy conscious and practical way remains extremely difficult).

➤ Ofcom will also be tasked with conducting an urgent review its enforcement capabilities with a clear enforcement strategy to be published as soon as possible. The government said they would ensure Ofcom has the funding it needs to carry out its new responsibilities – as well as continue its vital work to enforce the existing provisions of the Online Safety Act.

However, it’s worth noting that this change will also inhibit children from being able to fully engage with other young people across the country, and indeed the world, in order to raise awareness about issues they care about, either in terms of education, politics or on more sensitive subjects. For example, the likes Greta Thunberg or Malala Yousafzai may have found it much harder to get their views heard with a social media ban in the way. Not to mention that it treats 14-16 year olds with the same brush as much younger children, which some may find insulting.

The Australian attempt to introduce a similar ban also showed how difficult it is to do, with children frequently finding ways around the restrictions so they can stay engaged with their friends and family. According to the Molly Rose Foundation, some 61% of Australian 12-15 year-olds who had accounts on restricted platforms before the ban came into force still have access to one or more of them.

Sir Keir Starmer, Prime Minister, said:

“Parents want to keep their kids safe and happy, but the online world has made that harder than ever.

I’ve heard first hand from families crying out for change and we will do right by them.

That’s why we’re going further than any country in the world by banning social media for under-16s and putting wider protections in place to give kids their childhood back.

This is a line in the sand. Tech giants had their chance and failed, but we’re stepping in to protect children, back parents and set a new normal for future generations.”

An Ofcom spokesperson said:

“So far, Ofcom has driven some of the strongest changes of any online safety regulation in the world, from widespread age checks to grooming protections for children. But the industry needs to go much further to make people safe. The Government has entrusted us to build on this progress with new measures to protect children, and we’re ready to work closely with them as the detailed regulations take shape.”

Announcing the new measures is one thing, but actually introducing them is going to be extremely difficult, particularly given the diversity and complexity of the internet (i.e. there are many ways to get around Age Verification measures). Not to mention the risk of pushing younger users into underground groups and services, away from the big social media platforms.

Restricting access to common online services will also inhibit their use by adults and could this risk significant unintended consequences, particularly if restrictive rules are later applied to website and online services of all sizes with user-to-user platforms (e.g. smaller sites / forums and services often have no viable way of adding Age Verification). The result could be censorship by the backdoor of excessive legal liability.

At the same time many adults may be uncomfortable with being blocked from accessing communication / chat services until such time as they agree to share their personal biometric or financial data with often unknown, unfamiliar and unregulated third-party Age Verification organisations. Some of this has already occurred under the existing Online Safety Act (OSA).

James Baker, Freedom of Expression Programme Manager (Open Rights Group), said:

“Every failed attempt to make children safer online is followed by more surveillance and censorship.

Children have rights too and these policies will harm their free expression and privacy rights, and push them into less regulated spaces.

Meanwhile the business models driving harms are untouched.”

Today’s action also builds on the government’s work to date. Last week, the Prime Minister said Britain will be the first country in the world to make it “impossible for children to take, share or view nude images” – with a 3-month deadline to make meaningful progress. But not everybody will like the idea of the Government having such control over individual devices (Smartphones etc.). As usual, the focus is on children, but it may also impact adults.

The reality is that, whatever the government introduces, children who go seeking access to such systems and content will always find a way to circumvent any measures that are introduced – just as they always have done. Instead, it often ends up being the innocent and harmless online services, games and security systems that could be hurt the most by a sledgehammer approach to age-gated internet censorship.

The government appear to be trying to balance some of these concerns by directly focusing most of their efforts on the largest social media platforms, but it remains to be seen how workable all these changes are and how many smaller online sites and services it could actually end up catching.

The first set of regulations are intended to be brought into effect in Spring 2027.

Faster Onboard WiFi Coming to Lumo’s East Coast Main Line Trains this Autumn | ISPreview UK

Original article ISPreview UK:Read More

Open access rail operator Lumo has announced that they’re working with satellite broadband operator Starlink to deploy faster “next-generation” Wi-Fi for passengers onboard their fleet of 100% electric East Coast Main Line trains in time for this Autumn (2026) – travelling between London King’s Cross, Stevenage, Newcastle, Morpeth, Edinburgh Falkirk and Glasgow.

The Starlink system will provide the backhaul data capacity for the new service via their mega constellation of ultrafast and low-latency broadband satellites in Low Earth Orbit (LEO). The upgrade project will also be supported by train manufacturer, Hitachi, integrated connectivity provider Icomera and rolling stock lease provider Beacon Rail.

NOTE: The Government’s 10 Year Industrial Strategy last year pledged £41m to help introduce Low Earth Orbit (LEO) broadband satellite connectivity “on all mainline trains” in order to tackle the issue of poor onboard connectivity. Meanwhile, Project Reach is separately working to deploy “ultra fast fibre optic cable” across 1,000km of major rail lines to help “eliminate mobile signal blackspots” in tunnels on “key rail routes”.

According to the announcement, the new system is designed to “provide faster, more reliable connectivity throughout customer journeys“, although it’s not clear how they plan to tackle tunnelled sections (some ECML tunnels have already benefitted from a 4G mobile system being deployed).

Paul Jackson, Head of Customer and Stakeholder Engagement, said:

“Providing a high-quality, reliable Wi-Fi experience is vital for our customers, whether they’re travelling for business or leisure. We know people want to stay connected and work effectively while onboard.

The introduction of Starlink technology on our East Coast Main Line services marks a significant step forward in connectivity. Working with Hitachi and Icomera, we’re committed to delivering a modern, seamless experience that helps customers get the most out of their journey with Lumo.”

Lumo has previously also demonstrated a 5G-enabled Wi-Fi solution on its new West Coast services, operating between London Euston and Stirling, one of few offerings of its kind in the UK rail industry. Credits to Jamie for the news tip.
