Alpha ROV Brings Advanced Capability to Submarine Cable Maintenance

The Alpha ROV is designed and manufactured by Orange Marine at its facility in France. It has been developed specifically for telecommunications and power subsea cable operations, making it well suited for the demands placed on a modern cable repair fleet.

From a technical standpoint, the Alpha ROV features 450 kW of installed power, with 300 kW dedicated to jetting. It is capable of operating at depths of up to 3,000 metres and can carry out cable burial operations down to three metres, depending on seabed conditions. The vehicle uses a tracked configuration that can be adapted to a free-swimming mode, offering flexibility across different mission profiles.

The ROV supports a broad range of subsea operations. These include cable detection, inspection and survey, cutting and gripping, and burial and reburial. Importantly, the unit being supplied to Global Marine will be customized to meet the specific operational requirements of the company’s future cable maintenance vessel. This level of tailoring is expected to strengthen how the cable repair fleet performs across inspection, maintenance, protection and repair tasks on submarine cable systems worldwide.

New Hybrid Vessel Under Construction

The Alpha ROV is set to operate aboard Global Marine’s next-generation cable maintenance vessel, which is currently under construction at Colombo Dockyard in Sri Lanka. The vessel is scheduled for delivery in Q4 2029 and has been designed specifically for fiber-optic submarine cable repair operations. It is a hybrid-powered vessel, reflecting growing industry attention to fuel efficiency and environmental responsibility in subsea cable operations.

Once delivered, the combination of the new vessel and Alpha ROV will form a significant enhancement to the cable repair fleet. The pairing is expected to provide Global Marine with improved capabilities for submarine cable maintenance across inspection, protection and repair activities. This future capability positions the company to support long-term maintenance agreements with cable owners operating critical undersea infrastructure.

The collaboration between Global Marine and Orange Marine brings together decades of experience in subsea cable operations. Orange Marine has built specialized engineering and industrial expertise in the design and manufacture of subsea vehicles over several decades in France, supporting multiple operators in the submarine cable industry with vehicles, long-term maintenance support and, in some cases, dedicated operational teams. Global Marine’s decision to adopt the Alpha ROV for its cable repair fleet reflects the growing need for technologically advanced and operationally flexible assets as demand for submarine cable maintenance continues to rise alongside global network expansion.

The trial was led by ACO Solutions as systems integrator, with Hispasat acting as distribution partner alongside Eutelsat. Conducted on routes linking Kozłów, Warszawa and Tczew, the test used a Kymeta Kestrel u5 terminal that has received rail certification from TÜV Rheinland.

Testing Satellite Links on an Active Rail Network

The Kestrel u5 terminal is designed for mobile rail environments and carries an IP69K rating for protection in demanding operating conditions. It also has average power consumption of less than 100W. During the trial, Eutelsat evaluated LEO rail connectivity on a live railway network and collected performance data while assessing switching between satellite and terrestrial connectivity throughout the journey.

This approach is important for rail operators because communications requirements extend beyond passenger internet access. The tested solution is designed to combine OneWeb satellite connectivity with existing rail communications infrastructure, supporting passenger connectivity, operational communications and data services. LEO rail connectivity can also interface with onboard and trackside systems, helping maintain links between field operations and railway control centres.

Supporting Future Passenger and Freight Operations

The trial also tested the potential role of LEO rail connectivity across both passenger and freight rail services. By combining satellite links with existing communications infrastructure, the solution is intended to provide rail operators with additional connectivity options across routes where consistent terrestrial coverage can be challenging.

For passenger services, the technology can support connectivity needs while trains remain in motion. For railway operations, the same infrastructure can support communications and data exchange between onboard equipment, trackside systems and operations centres. The live test therefore provides a practical setting for assessing how LEO rail connectivity can function alongside established terrestrial networks. This is particularly relevant as rail operators expand digital services and require communications systems that can support both onboard applications and operational requirements across moving trains.

Eutelsat said the successful trial demonstrates the ability of its OneWeb network to support rail connectivity in real operating conditions. The company and its partners can now use the performance data gathered during the test to further assess the technology for rail applications in Poland and other markets.

The development remains a trial rather than a commercial rollout across Poland’s railway network. However, the completion of the test on an active long-distance service provides a concrete demonstration of how LEO rail connectivity can be evaluated for future rail communications and data requirements.

Voice Fraud is Moving from Spoofed Numbers Toward Synthetic Identities

Caller-ID spoofing can make a call appear familiar, while a synthetic voice can make the conversation itself more convincing. An attacker can combine these techniques with social engineering to create a compound attack that is harder to assess through conventional caller cues.

INTERPOL’s 2026 Global Financial Fraud Threat Assessment reports that convincing voice clones can be created from as little as 10 seconds of audio in some circumstances. The report also identifies AI-enabled fraud services offering synthetic identity capabilities.

The security challenge is therefore moving beyond whether a number appears trustworthy. synthetic voice telecom fraud can exploit the gap between verified caller information and the apparent authenticity of the speaker.

Caller Authentication Does Not Establish Voice Authenticity

Caller authentication and voice authenticity answer different security questions. Network controls can help establish whether a calling number has been legitimately presented, while voice analysis can assess whether audio has characteristics associated with synthetic generation or manipulation.

A legitimate number can therefore still be used with a convincing cloned voice to persuade a recipient to disclose information or authorise an action. As telecom security expands across network infrastructure and identity controls, caller identity controls, voice security is becoming another layer in the wider security lifecycle.

Synthetic voice telecom fraud consequently creates a need for multiple independent signals rather than relying on a telephone number or voice impression alone.

Key Takeaway: Synthetic voice is making impersonation more convincing, increasing the need for layered caller authentication and network-level voice security.

Voice Security is Moving Toward Layered AI and Caller Verification

The emergence of synthetic audio is pushing telecom security beyond traditional caller screening. A network can establish information about a calling number, but that does not necessarily establish whether the voice itself is authentic. This is making synthetic voice telecom fraud increasingly dependent on multiple security signals, including caller identity, signalling information, call behaviour and AI-based audio analysis.

AI Detection is Moving into the Voice Network

Traditional approaches to unwanted calls have relied on reputation databases, known-number lists and traffic patterns. Synthetic voice creates a more adaptive threat because the audio can be generated or modified for each interaction. Detection systems therefore need to identify suspicious combinations of network and behavioural signals rather than relying on a single indicator.

GSMA’s 2026 case study on network-level voice protection describes AI-based systems analysing billions of call events and adapting to changing scam patterns. Hiya’s current voice-security network analyses approximately 28 billion calls per month across more than 40 countries, illustrating the scale at which automated call-risk analysis is increasingly being performed.

For synthetic voice telecom fraud, this creates a shift from static blocking toward continuous analysis. A suspicious call can potentially be assessed using the calling number, network characteristics, calling behaviour and other available signals before the recipient decides whether to trust the interaction.

Caller Verification is Adding Another Security Layer

AI-based audio detection is not the only response. Telecom and industry initiatives are also working on stronger ways to establish who is authorised to make a call.

Open Verifiable Calling, for example, is designed around cryptographically verifiable caller identity, allowing organisations to demonstrate that a number is associated with an authorised entity before the call reaches the recipient. This approach addresses a different part of the problem from synthetic-voice detection: rather than asking only whether the audio sounds genuine, it establishes whether the caller has a verifiable identity.

These approaches can therefore complement each other, Caller Verification, Who is making the call?, Voice Analysis, Does the audio show signs of manipulation and Network Intelligence, What additional context surrounds the call?

Together, these layers can provide more information for security decisions than any single control.

Synthetic Voice is Increasing Pressure on Detection Systems

Voice-security models also face a moving target. New synthesis techniques can produce different acoustic characteristics, while compression, background noise and network conditions can alter genuine and synthetic audio. Recent research on voice-authentication threats notes that anti-spoofing systems can struggle with previously unseen attack techniques, reinforcing the need for continuous evaluation and adaptation.

This makes synthetic voice telecom fraud a wider network-security problem rather than a problem that can be solved only through an audio classifier. Detection, caller verification and network-level intelligence increasingly need to operate together.

Voice Security is Becoming a Network Responsibility

Telecom voice security is increasingly moving beyond caller-ID protection toward a layered model that combines identity verification, signalling intelligence and analysis of the voice itself. Synthetic voice telecom fraud highlights the limits of relying on any single indicator, particularly when attackers can combine legitimate-looking numbers with AI-generated speech and social engineering.

Protecting voice services therefore requires cooperation between network operators, technology providers and the organisations receiving calls. Cryptographically verifiable caller identity, network-level monitoring and adaptive detection can provide complementary signals while maintaining appropriate controls over sensitive communications data.

Tele Info Today notes that the broader challenge is restoring trust in voice communications as synthetic audio becomes more accessible. As telecom networks strengthen caller verification and real-time detection, voice security is becoming an increasingly integrated part of the wider cybersecurity architecture supporting digital communications.

Telecom Networks are Becoming Sources of Fraud Signals

A financial institution can identify an unusual login or transaction, but it may not independently know whether a customer’s SIM was recently replaced or whether the mobile number is still associated with the device being used. Telecom operators can provide those signals because the network has direct visibility into subscriber and device relationships.

This creates an additional layer of risk intelligence. Number Verification can help confirm whether the mobile number being used by an application matches the number associated with the mobile connection. SIM Swap can indicate whether a recent SIM change has occurred, while Device Swap can identify a change in the relationship between a mobile number and physical device.

These capabilities do not determine that fraud has occurred. Instead, they give an external service another security signal that can be combined with transaction behaviour, account history and authentication data. Network API fraud prevention therefore works as part of a broader risk-assessment process rather than as an isolated fraud-detection tool.

Network APIs are Making Security Signals Accessible

The development is being supported by the GSMA Open Gateway and CAMARA ecosystems, which are creating standardised interfaces for exposing selected mobile-network capabilities to authorised applications. In March 2026, GSMA reported that its Open Gateway framework covered 86 operator groups and more than 300 networks, representing 80% of global mobile connections.

The scale of the ecosystem matters because fraud-prevention applications become more practical when they can access consistent network capabilities across multiple operators and markets. Standardised APIs can reduce the need for separate integrations while allowing operators to retain control over how network information is exposed.

For network API fraud prevention, this creates a new relationship between telecom cybersecurity and external digital services. Network security signals can move through controlled interfaces into fraud-management systems, where they can help determine whether an interaction requires additional verification or intervention.

Key Takeaway: The expanding global network-API ecosystem is creating a wider infrastructure through which trusted telecom security signals can support fraud prevention beyond the operator’s own network.

Telecom Equipment is Entering a Wider Security Perimeter

Mobile and fixed networks depend on hardware, software and firmware supplied by third parties, meaning a weakness in one component can create security implications across connected infrastructure. The UK’s revised Telecommunications Security Code of Practice 2026 requires public telecom providers to manage supplier security risks and contractually require third-party network-equipment suppliers to maintain vulnerability disclosure policies. It also requires suppliers to support investigations and remediation when their products contribute to a security compromise.

This is making telecom vulnerability reporting part of a wider supplier-governance process. Operators need timely information on affected products, while suppliers need processes for communicating security incidents, identifying root causes and supporting corrective measures throughout the equipment lifecycle.

Reporting Requirements are Becoming More Time-Bound

The regulatory direction is also becoming more explicit around reporting speed. Since 11 September 2026, manufacturers covered by the EU Cyber Resilience Act have been required to report actively exploited vulnerabilities and severe incidents affecting products with digital elements through ENISA’s Single Reporting Platform. The framework requires an early warning within 24 hours and a fuller notification within 72 hours.

As disclosure becomes more structured, security attention also moves toward network signalling mechanisms, where weaknesses in network communication and fallback processes can create additional exposure. Telecom vulnerability reporting is consequently becoming part of a security lifecycle linking manufacturers, suppliers and operators.

Key Takeaway: Vulnerability management is becoming more time-bound, with reporting, supplier notification and remediation increasingly built into telecom security responsibilities.

Supplier Vulnerability Management is Becoming More Structured

The expansion of vulnerability reporting requirements is changing how telecom operators manage relationships with equipment suppliers. Security expectations increasingly extend into procurement, contractual controls, disclosure procedures, patch management and incident response. Suppliers are being asked to provide clearer information about vulnerabilities and support operators in addressing issues that could affect live networks.

This is making telecom vulnerability reporting more closely connected with supplier governance. A notification has limited operational value if an operator cannot determine which products are affected, how exposed they are or what remediation is available. The process therefore needs to connect vulnerability information with asset inventories, software versions and remediation workflows.

Supplier Security Requirements are Moving into Contracts

Contracts can translate security expectations into specific responsibilities. The UK’s revised Telecommunications Security Code of Practice 2026 requires public telecom providers to contractually oblige relevant third-party suppliers to report certain security incidents within 48 hours, support investigations and identify root causes. It also requires providers to verify that network-equipment suppliers maintain vulnerability disclosure policies.

These requirements make telecom vulnerability reporting part of an ongoing relationship between operators and suppliers rather than an isolated notification event. A supplier may need to identify affected products, provide technical details, support impact assessments and help determine corrective action.

Remediation is Becoming Part of the Reporting Lifecycle

The next step after disclosure is determining how quickly and safely a vulnerability can be addressed. Telecom networks can contain large numbers of distributed equipment instances, and operators may need to test patches, schedule deployments and maintain service continuity while remediation takes place.

The UK’s 2026 code states that patches addressing exposed, actively exploited vulnerabilities should be deployed as soon as reasonably achievable and at most within 14 days of release. Asset visibility is therefore important because operators need to know where affected products are deployed.

Coordinated Disclosure is Connecting the Mobile Ecosystem

Security researchers, manufacturers, operators and industry bodies can hold different pieces of information about a vulnerability. The GSMA Coordinated Vulnerability Disclosure programme provides a structured route for researchers to report vulnerabilities affecting the mobile ecosystem and supports collaboration among operators, suppliers and standards bodies on fixes and mitigating actions.

The wider objective is to make vulnerability information actionable across the industry. Telecom vulnerability reporting increasingly needs to connect discovery with assessment, communication, remediation and verification, creating a lifecycle that extends from a supplier’s development environment to equipment operating inside a live telecom network.

The upgraded cloud native 5G core is designed to deliver a planned capacity of 9 terabits per second, positioning it among Europe’s largest mobile packet cores. That level of throughput is critical for meeting the growing data demands driven by streaming, gaming, Fixed Wireless Access home broadband and other bandwidth-intensive services across VodafoneThree’s base of 28.6 million customers.

Deployed on Ericsson’s Cloud Native Infrastructure Solution, the new core provides a simplified, more resilient and automated network environment. By unifying 4G and 5G core functions on a single platform, the architecture reduces complexity while laying the groundwork for 5G Standalone capabilities and advanced services such as network slicing.

Differentiated Connectivity Through Network Slicing

The cloud native 5G core underpins VodafoneThree’s introduction of differentiated connectivity services, including the recently launched Vodafone SuperMobile. The service delivers up to four times faster speeds and a minimum download speed guarantee of 15 Mbps when customers are within 5G Standalone coverage.

Two dedicated network slices support these capabilities. The 5G+ FastTrack slice gives consumers access to a dedicated portion of the network, helping data move faster and more reliably during periods of high demand. The National Business Slice separates business traffic from consumer demand, enabling up to four times faster speeds and committed performance targets so that employees, applications and critical workflows remain connected and productive.

VodafoneThree’s network slicing strategy builds on the 5G+ Local Slicing service launched by Vodafone Business earlier in 2026. That offering delivers contracted performance at specific high-density sites such as entertainment venues, travel hubs and logistics facilities. Looking ahead, VodafoneThree plans to launch a National Critical Slice in 2027, designed to give blue-light organisations and critical public services priority connectivity and assured performance for mission-critical operations.

From Shared Infrastructure to a Dedicated Core

The upgraded cloud native 5G core represents the second major phase of VodafoneThree’s ambitious network transformation. Earlier in 2026, VodafoneThree completed a world-first network upgrade that unified core-level sharing through Multi-Operator Core Network technology with its existing Multi-Operator Radio Access Network across a multi-vendor 4G and 5G network. That step enabled Vodafone and Three customers to automatically connect to the best available coverage from either network at no extra cost. The current deployment advances that work from shared infrastructure to a single, dedicated and highly advanced Ericsson 5G Core.

The core network project was originally contracted by Three UK in January 2025 to support increasing data demand. It has since been seamlessly integrated into the wider VodafoneThree network strategy. Ericsson serves as VodafoneThree’s sole vendor for the nationwide core network and provides the significant majority of its radio access network, as part of the eight-year partnership announced in September 2025. The ongoing modernisation also includes deployment of Ericsson’s latest energy-efficient radio hardware and smart multi-band antennas across major population centres.

Hrvoje Jerkovic, Network Engineering Director at VodafoneThree, said: “The activation of our new cloud-native 5G core network is a major milestone in our journey to build the UK’s best network. Following the successful integration of our radio networks earlier this year, we are now taking the next step by creating a single, highly advanced core network that will underpin the future of connectivity for consumers and businesses across the UK. Together with Ericsson, we are building a network designed for the demands of tomorrow, delivering greater capacity, resilience and performance, while creating the foundation for innovations such as network slicing and new AI-powered services.”
