How Vodafone UK Prepares its Network for Storms and Heatwaves

Extreme weather is a growing concern for mobile network operators, and Vodafone is no exception. Storms and heatwaves can damage infrastructure, interrupt power supply, and delay repair work. To keep people connected during such events, Vodafone has developed a range of technical measures and operational strategies that help it prepare for and respond to disruption.

The most exposed part of the network is the mast, which is usually above ground and can be up to 25 metres tall. While it is not possible to make these completely immune to bad weather, Vodafone designs them with resilience in mind. Many mast sites are equipped with backup batteries and generator connection points, provided there is space to install them safely.

Vodafone operates around 18,000 masts across the UK. Each one is part of the wider Radio Access Network, with traffic routed through dedicated signalling controllers hosted in secure data centres. These centres are equipped to maintain at least one mobile service, even in the event of a power outage, by prioritising the use of backup power.

In rural areas, some masts rely on microwave links instead of fibre or copper connections. These links require a clear line of sight between masts, so engineers carry out preventative maintenance to remove any vegetation that might interfere with signal transmission.

The Network Operations Centre (NOC) monitors the network and directs field engineers. During weather alerts, Vodafone increases staffing levels to improve response times and ensure the right resources are in place. Temperature sensors at mast sites detect heat-related issues and automatically alert the NOC if thresholds are exceeded. This can lead to quick interventions, such as cleaning or replacing clogged air filters in cooling systems.

If a mast repeatedly shows signs of overheating, the NOC flags it for further investigation. Possible solutions include enhanced maintenance schedules or upgrading the cooling technology. Despite all these precautions, access and repair work after storms or floods can still be complicated by damaged roads or infrastructure. Engineers may need to assess fibre cables, antennas or even the structural integrity of masts.

Where power supply is disrupted for extended periods, Vodafone’s network planners must carefully manage the use of batteries and generators. Coordination with external bodies such as the National Grid is often essential.

By investing in resilient infrastructure and ensuring rapid response capabilities, Vodafone aims to keep its mobile network running reliably, even in the face of increasingly unpredictable weather.

FDD Tri-Band Massive MIMO: Unlocking Sub-3 GHz Potential for 5G Evolution

Huawei has begun commercial deployments of its FDD Tri-Band Massive MIMO solution, focusing on sub-3 GHz spectrum across Africa and several other global markets. Countries such as Nigeria, Angola, and Côte d'Ivoire are among the first to benefit, with deployments also expected across Asia Pacific, Central Asia, and Latin America.

This new technology is being positioned to solve two key challenges for mobile operators. First, it tackles the persistent increase in 4G traffic, which continues to grow year on year. Second, it enhances the user experience for 5G services without demanding vast new spectrum allocations. Huawei claims the solution delivers significant performance improvements over the conventional 4T4R setup, including handling almost twice as much 4G traffic during peak times, tripling user-perceived speeds, and halving the use of physical resource blocks.

Underpinning these benefits are innovations like Real Wide Bandwidth and Compact Dipole technologies. These allow multiple FDD bands such as 1.8 GHz, 2.1 GHz, and 2.6 GHz to be processed using a shared filter, antenna array, and power amplifier. This not only enables efficient spectrum use but also simplifies site deployments. Huawei reports that 5G network capacity can be boosted up to sevenfold with uplink coverage extended by 8 dB, both of which are especially important as mobile AI services increase the demand for higher uplink bandwidth and wider coverage.

The market conditions in Africa illustrate why this approach is timely. Rapid urbanisation and a large population base have created surging demand for mobile data, leading to congestion and degraded user experience. Many sites already host conventional Massive MIMO technology, but with traffic increasing by 50 percent annually, a more efficient capacity solution is urgently needed.

The broader role of sub-3 GHz FDD spectrum in 5G development is also coming into sharper focus. While early 5G investment emphasised the upper mid-band due to its wide contiguous spectrum, the sub-3 GHz FDD bands now represent a crucial part of the coverage and capacity equation. These bands collectively offer around 100 MHz of paired spectrum and are essential for extending 5G services beyond dense urban centres into suburban and rural areas. Their propagation characteristics provide better in-building penetration and a stronger uplink experience.

Operators have traditionally used these bands to complement mid-band deployments, but case studies suggest they can form the backbone of high-performance networks when optimised correctly. In the Netherlands, for example, delays in mid-band spectrum availability led operators to rely heavily on FDD spectrum. Despite these constraints, they achieved strong data rate and latency performance by tightly integrating 4G and 5G technologies.

One persistent issue is the fragmentation of spectrum across multiple bands, which can complicate radio access network design. Physical site constraints and antenna complexity remain challenges, particularly as physical cell site growth slows. This has led to a push for site simplification through wideband and multiband radio solutions. Many equipment vendors now offer radios that can support three FDD bands within a single unit, often using a shared power amplifier and filter. This not only reduces size and weight but also lowers power consumption and speeds up deployment.

Although Massive MIMO is generally seen as more effective with TDD, Huawei believes its latest advancements in intelligent beamforming and multi-band serving cell configurations can change that narrative. By treating multiple FDD bands as a single carrier and applying advanced beamforming, spectral efficiency can be dramatically improved. According to Huawei, this combination can deliver a tenfold gain in throughput and a 10 dB improvement in coverage compared to standard 4T4R systems.

With the shift toward 5G Advanced on the horizon, operators must get the most out of their existing spectrum assets. Sub-3 GHz FDD spectrum may not be new, but with the right technology, it can provide the performance needed to meet modern data demands and support the next wave of mobile services.

Mobile Internet Setup for Vanlife: Infrastructure Insights from The Road Two Spoons

In today’s age of digital nomadism, mobile connectivity isn’t a luxury—it’s a necessity. For vanlifers like Jess and Marcus, better known as The Road Two Spoons, staying online while travelling full-time across Europe and Türkiye requires more than just a mobile hotspot. Their campervan serves as both home and office, meaning a robust and redundant internet setup is essential.

Their upgraded system offers a great case study into the infrastructure behind reliable van-based internet. It combines cellular and satellite connectivity with intelligent routing and efficient power use—demonstrating how mobile networking hardware can be optimised for life on the road.

The Core: A Multi-Path Internet Router

At the heart of the setup is the Teltonika RUTX50, a compact yet powerful 3G/4G/5G modem-router that supports multiple WAN inputs and advanced network management. Key features include:

  • Dual SIM support for redundancy (though only one slot is currently in use)
  • Auto-switching and load balancing capabilities
  • A low power draw suitable for off-grid living
  • 12V operation with physical on/off switching
  • Multiple antenna ports: 4 x SMA for 5G, 2 x ReSMA for Wi-Fi, and 1 x SMA for GPS
  • 5 x Gigabit Ethernet ports for flexible wired connections

The router integrates seamlessly with both a 5G antenna and a Starlink dish, offering connectivity even in the most remote regions.

Cellular Connectivity: Poynting Antenna Integration

For cellular signal reception, the van uses a Poynting MIMO-4-4 5G antenna. This external, roof-mounted unit connects directly to the RUTX50 to ensure strong signal acquisition, especially in fringe coverage areas.

This antenna enhances the performance of their ConnectPls Europe unlimited data SIM, providing primary connectivity when Starlink is unavailable or switched off. The setup allows automatic failover between cellular and satellite internet sources, keeping downtime to a minimum.

Satellite Support: Starlink Gen3 + Starvmount

Mounted securely on the van roof is a Starlink Gen3 (V4) dish, using the Starvmount DishyMultiMount. This combination ensures:

  • Flat, in-motion satellite connectivity via Starlink Roam
  • Fixed mounting at an optimal 8° angle, aiding both signal quality and weather resilience
  • Improved mechanical security over Starlink’s original mobility mount

Thanks to Starlink’s global coverage and low-Earth orbit satellite constellation, the couple can achieve 200+ Mbps speeds in locations where even sending a text would otherwise be impossible.

Power Considerations: 12V Starlink Conversion

To avoid reliance on inverters and 230V AC power, the Starlink system runs directly off the van’s 12V power system using a Starvmount Dishy NoAC DC power supply. This device:

  • Accepts a wide input voltage (9–36V), suitable for 12V or 24V installations
  • Offers plug-and-play integration between the Starlink dish and the RUTX50
  • Eliminates the need for Starlink’s original AC-powered router
  • Emits a minor static noise under load, so is ideally installed in a cupboard or enclosed space

A dedicated 12V switch allows the system to be powered down when not in use, contributing to overall energy efficiency.

Cabling and Waterproofing: Roof-Grade Sealing

Cables for both Starlink and the Poynting antenna are routed through the van’s roof using Scanstrut DS-H-MULTI-BLK cable seals. These seals are:

  • IP68-rated for waterproofing
  • UV-stable to withstand prolonged sun exposure
  • Trusted for roof penetrations in marine and automotive applications

This careful attention to weatherproofing ensures long-term reliability of the system, even in extreme environments.

One Wi-Fi Access Point, Seamless Switching

Because both Starlink and cellular data feed into the same RUTX50 router, the van operates a single internal Wi-Fi access point. The router automatically prioritises the Starlink connection when available, and falls back to the SIM card with minimal delay when Starlink is powered off.

This means no manual reconfiguration is required, simplifying the digital experience onboard and allowing Jess and Marcus to focus on their work, travel, and content creation.

Final Thoughts: Engineering Freedom on Four Wheels

What makes this campervan internet setup impressive is not just the performance, but the thoughtful integration of multiple technologies: 5G, satellite broadband, power management, and rugged installation. By combining a modular approach with careful hardware selection, The Road Two Spoons have created a high-reliability infrastructure that could easily be adapted to off-grid cabins, remote workstations, or mobile command vehicles.

As connectivity becomes more critical in all forms of modern living, this vanlife case study offers valuable insights into how telecom infrastructure can be effectively deployed outside traditional settings—bringing reliable broadband to wherever the road leads.

Meta's Project Waterworth: The Next Evolution in Subsea Connectivity

Meta has unveiled its most ambitious subsea cable project to date — Project Waterworth, previously referred to as "W", because of it's shape. The multi-billion-dollar initiative is set to become the longest subsea cable in the world, spanning over 50,000 km and connecting five major continents, including the U.S., India, Brazil, and South Africa. With 24 fibre pairs delivering the highest capacity technology available, Project Waterworth will redefine global digital infrastructure and enhance connectivity for billions of users.

Subsea cables form the backbone of the internet, carrying more than 95% of intercontinental traffic and enabling global communication, financial transactions, and AI-driven innovations. With this latest venture, Meta aims to open three new oceanic corridors, ensuring high-speed, reliable connectivity that will power the next wave of AI advancements worldwide. By leveraging cutting-edge routing techniques, enhanced burial methods in high-risk areas, and deep-sea deployments up to 7,000 metres, Project Waterworth is designed for maximum resilience and security.

India at the Centre of Meta’s Connectivity Vision

India is central to Meta’s strategy, with its platforms—Facebook, Instagram, and WhatsApp—serving over a billion users in the country. With AI adoption accelerating, demand for data centre capacity and seamless connectivity is at an all-time high. Project Waterworth is expected to play a pivotal role in supporting India’s digital economy by providing the necessary infrastructure to handle AI workloads, cloud services, and high-speed internet demands.

The project also underscores Meta’s shift in subsea cable strategy. Unlike its earlier 2Africa initiative, which followed a consortium approach, Project Waterworth appears to be a fully owned and controlled system. This mirrors Google's model of securing dedicated infrastructure for strategic markets rather than relying on shared capacity. While this approach ensures end-to-end control and security, it diverges from the collaborative model that has been highly successful in previous large-scale subsea cable projects.

Bypassing Global Chokepoints

One of the key aspects of Project Waterworth is its avoidance of politically sensitive and high-risk regions. Meta has reportedly designed the cable to steer clear of the Red Sea, the South China Sea, Egypt, and the Malacca Strait—areas that have become significant geopolitical bottlenecks for global internet traffic. By taking a direct route between the U.S. and India with strategic stops in South Africa and potentially Australia, Project Waterworth aims to ensure long-term security and avoid the risks associated with conflict zones and regulatory challenges in transit countries.

However, this bypassing of traditional routes does come with a trade-off: increased latency. Despite this, Meta appears to prioritise long-term security and reliability over marginal improvements in data transmission speeds. The project will also likely face regulatory hurdles, particularly in India, where obtaining permits for marine surveys and installations is notoriously complex and time-consuming.

The Battle for AI Connectivity Dominance

Meta’s decision to fully own Project Waterworth could have wider implications for the subsea cable industry. If Meta excludes partners, it may push competitors like Google to develop their own dedicated infrastructure to serve India’s growing digital ecosystem. Given the scale of investment—potentially exceeding $10 billion over the next decade—this move signals a new era of tech giants building independent, AI-optimised connectivity solutions.

While Project Waterworth marks a significant leap forward in global connectivity, the challenge will be balancing rapid deployment with regulatory constraints. If successful, it will not only strengthen Meta’s position as a digital infrastructure leader but also cement India’s role as a global AI powerhouse in the decades to come.

Electric Vehicles as a Resilient Power Source for Telecom Infrastructure

In an era where reliable telecommunications infrastructure was critical, Japan’s telecom giant NTT DOCOMO, in collaboration with NTT Corporation and Nippon Car Solutions (NCS), launched a ground-breaking demonstration experiment to enhance base station power resilience during outages. This initiative explored the feasibility of using electric vehicles (EVs) as mobile power sources, supported by AI-driven dispatch planning.

Addressing the Challenge of Power Outages

Telecom networks rely on consistent power to maintain connectivity, especially during emergencies. Traditionally, base stations depend on backup batteries with limited capacity, supplemented by generators in prolonged outages. However, with the increasing adoption of EVs, their potential as mobile energy sources offered a novel and sustainable approach to bolstering telecom infrastructure resilience.

The experiment integrated multiple technological components:

  • DOCOMO’s Energy Management System (EMS): This platform monitored the charge status of base stations and coordinated power-sharing between EVs and telecom infrastructure.
  • NTT’s AI-Based Dispatch Planning: Leveraging deep reinforcement learning, this system dynamically optimised EV dispatch to ensure timely power delivery to affected base stations.
  • Real-time EV Data Collection: Provided by NCS, this component tracked EV location, stored power, and driving data to enhance operational efficiency.

A Smart, AI-Driven Approach

One of the key innovations in this experiment was the use of AI-driven route planning to deploy EVs effectively. The AI system not only determined the fastest routes for EVs to reach power-downed base stations before backup batteries depleted but also ensured that vehicles were directed to charging stations before their own power ran low. By optimising travel and energy allocation, the AI model addressed logistical challenges that could otherwise hinder the feasibility of EV-based power support.

The trial, conducted in Chiba Prefecture, simulated wide-area power outages and assessed the effectiveness of the AI dispatch model in real-world conditions. By driving EVs according to AI-generated plans and measuring the charging effectiveness at base stations, the experiment aimed to refine this approach for broader adoption.

Sustainable and Scalable Solutions for Future Telecom Networks

Beyond immediate disaster response, this initiative aligned with broader sustainability goals. As a member of the EV100 initiative, NTT was committed to accelerating the adoption of electric vehicles within corporate fleets. Integrating EVs into telecom infrastructure resilience strategies not only enhanced disaster response but also contributed to reducing carbon footprints in the industry.

If successful, this model could be used as a blueprint for telecom operators worldwide, particularly in regions prone to natural disasters. By leveraging AI, energy management systems, and EV technology, telecom networks could build a more resilient, flexible, and sustainable power backup strategy.

This forward-thinking trial underscored how emerging technologies could be harnessed to address infrastructure vulnerabilities, ensuring uninterrupted connectivity when it mattered most. As the telecom industry continued to evolve, integrating intelligent, sustainable power solutions remained key to enhancing network reliability and disaster preparedness.

Decoding Starlink: The Technology Behind the Revolution

Starlink has been a regular feature on our blog. The race to provide global connectivity has seen remarkable innovation, and Starlink, SpaceX's satellite internet service, has been at the forefront. By utilising a network of low Earth orbit (LEO) satellites, Starlink promises faster speeds and reduced latency compared to traditional satellite internet. But what exactly sets Starlink apart? Let’s delve into the technical marvels behind this ground-breaking system.

Traditional broadcast satellites operate in geostationary orbits, approximately 35,000 kilometres above Earth. In contrast, Starlink's LEO satellites, orbiting at altitudes of around 550 kilometres, drastically reduce the distance signals travel. This significantly enhances performance and reduces latency, forming the foundation of Starlink’s technological advantage.

With Starlink internet, data is continuously exchanged between a ground dish and a Starlink satellite zooming across the sky at an incredible 27,000 km/h. How can the dish and satellite maintain a continuous connection? And how is data transmitted so efficiently? The video below delves deeply into the workings of the ground dish and satellites, revealing how a beam of data is formed, how it is swept across the sky, and what precisely is in that beam enabling incredibly fast internet speeds. This is a remarkable feat of technology and engineering!

Inside the Starlink Dish: Dishy McFlatface

At the heart of the Starlink system is its ground terminal, affectionately known as Dishy McFlatface. This device features an aperture-coupled patch antenna, a sophisticated design that allows it to efficiently emit and receive electromagnetic waves. Unlike traditional parabolic dishes, Dishy is compact, sleek, and meticulously optimised for Starlink’s specific needs.

How Does Dishy Work?

Dishy’s ability to send and receive data hinges on two critical technologies: beamforming and phased array beam steering.

  • Beamforming enables the dish to focus its electromagnetic waves into a directed beam, efficiently reaching Starlink satellites in orbit.
  • Phased Array Beam Steering introduces dynamism, allowing the beam to move across the sky by electronically adjusting the phase of signals emitted from various antenna elements. This agility is essential for maintaining a seamless connection with rapidly moving LEO satellites.

A Look at Signal Transmission

Once a beam is formed and directed, Dishy employs advanced modulation techniques, such as 64QAM (Quadrature Amplitude Modulation), to transmit data. This method combines amplitude and phase variations, maximising data throughput—a vital requirement for high-speed internet services.

Scaling Down: Electromagnetic Waves and Dishy’s Dimensions

Despite its advanced functionality, Dishy remains surprisingly compact. This miniaturisation is achieved by leveraging the properties of electromagnetic waves and employing innovative design principles, as outlined in Starlink’s patents.

The Bigger Picture

Starlink’s phased array technology represents a monumental leap in satellite communications, with implications extending beyond internet services. Its ability to dynamically steer beams has the potential to revolutionise fields such as autonomous vehicles, IoT, and remote sensing.

Conclusion

Starlink isn’t merely about providing internet access; it’s about redefining the very concept of connectivity. Through ground-breaking innovations in satellite placement, ground terminal design, and signal processing, Starlink sets a new benchmark for telecom infrastructure.
