Tech News : First Video Call via Satellite in No-Signal Zone

Vodafone has successfully conducted the world’s first satellite-enabled video call using a standard 4G/5G smartphone from a location devoid of terrestrial mobile coverage.

The Call

Vodafone has reported that recently (the exact date has not been specified), an engineer from the company, Rowan Chesmer, initiated a video call from a remote mountainous area in mid-Wales, which is a region historically lacking mobile broadband access, i.e. it has ‘not spots’. Using a standard Android smartphone, Chesmer connected directly to a Low Earth Orbit (LEO) satellite operated by AST SpaceMobile, a partner of Vodafone. The call was received by Vodafone Group Chief Executive Margherita Della Valle at the company’s UK headquarters in Newbury, Berkshire. This event was further distinguished by the presence of British astronaut Tim Peake, who joined Della Valle to commemorate the achievement.

Vodafone is keen to highlight the call as being a milestone that could signify a significant leap towards universal connectivity, potentially bridging the digital divide in remote and underserved regions.

The Mechanism

The success of this endeavour hinges on the integration of standard smartphones with LEO satellites. Unlike traditional satellite phones, which are often bulky and require specialised equipment, Vodafone’s approach allows regular smartphones to connect directly to satellites without the need for additional hardware. The process involves the smartphone communicating with the satellite, which then transmits data to and from a ground-based relay station. This relay station is connected to Vodafone’s terrestrial network, facilitating seamless communication between the satellite and ground infrastructure.

Implications for Vodafone Users

This technological advancement promises to eliminate mobile coverage ‘not-spots’, i.e. the areas where traditional mobile signals are unavailable. For Vodafone users, this means the potential for uninterrupted connectivity, even in the most remote locations. The service aims to mirror the experience of existing 4G and 5G networks, enabling users to make video calls, access the internet, and use online messaging services without any noticeable difference. Importantly, users will not need to invest in specialised devices (their existing smartphones will suffice).

The Projected Rollout Timeline

While the initial test was successful, Vodafone says it plans to conduct further evaluations throughout the spring. The company says it’s aiming to progressively introduce the direct-to-smartphone broadband satellite service commercially in markets across Europe later this year and during 2026. It hopes that this phased rollout approach will ensure the technology is robust and reliable before widespread deployment.

The Broader Impact on the Telecommunications Industry

Vodafone’s achievement sets a new benchmark in the telecommunications sector, highlighting the feasibility of integrating satellite connectivity with standard mobile devices. This development is likely to prompt other mobile operators to explore similar technologies to enhance their coverage and service offerings. Notably, companies such as AT&T and Verizon have also partnered with AST SpaceMobile to develop satellite-based mobile broadband services, indicating a broader industry trend towards leveraging satellite technology for comprehensive coverage.

What’s Been Said About It?

All the key players at Vodafone and its partners have been keen to highlight the significance of this milestone and what it could mean. For example, Margherita Della Valle, Vodafone Group Chief Executive, said: “Vodafone’s job is to get everyone connected, no matter where they are” and that “This will help to close the digital divide, supporting people from all corners of Europe to keep in touch with family and friends, or work, as well as ensuring reliable rural connectivity in an emergency”.

UK Astronaut Tim Peake has also reflected on Vodafone’s achievement, saying: “Having spent six months on the International Space Station, I can fully appreciate the value in being able to communicate with family and friends from remote and isolated locations. I am delighted to join Vodafone and AST SpaceMobile in this significant breakthrough.”

Abel Avellan, Founder, Chairman, and CEO of AST SpaceMobile, highlighted the collaborative effort involved, saying: “This historic milestone marks another significant step forward in our partnership with Vodafone, a long-time investor in AST SpaceMobile and a key technology partner. Together, we have achieved several world firsts in space-based broadband connectivity.”

Technical Specifications and Capabilities

The satellite system employed in the test used AST SpaceMobile’s BlueBird satellites, which operate in Low Earth Orbit at approximately 500 km above the Earth’s surface. This proximity allows for lower latency and faster data transmission compared to traditional geostationary satellites. The system is designed to provide peak data transmission speeds of up to 120 Mbps, supporting a full mobile broadband experience. Also, the technology employs beamforming techniques to direct radio signals precisely, enhancing speed and minimising interference.

Why Is Direct-To-Phone Satellite Different?

While some smartphones, such as recent iPhone models, offer emergency SOS features via satellite, these services are limited to text messaging and require clear line-of-sight to the sky. In contrast, Vodafone’s direct-to-phone satellite service aims to provide a comprehensive mobile broadband experience, including video calls and internet access, without the need for specialised equipment or ideal environmental conditions.

Drawbacks

While Vodafone’s satellite-enabled smartphone video call marks a major breakthrough, several challenges remain. Early tests revealed issues with connection quality, including choppy video and noticeable lag due to higher latency and lower bandwidth than traditional networks. Regulatory hurdles could also slow progress, as securing spectrum approvals and navigating complex legal frameworks take time. Also, some critics argue that eliminating mobile ‘not-spots’ may reduce opportunities for solitude and digital disconnection. Astronomers have raised concerns about the increasing number of satellites interfering with space observations and asteroid detection. Lastly, Vodafone has yet to disclose pricing details, raising questions about affordability, as satellite communication has historically been costly. Addressing these issues will be key to ensuring a smooth and responsible rollout of the technology.

Looking Ahead

The successful demonstration of satellite-enabled video calls using standard smartphones could open new avenues for global connectivity. As Vodafone and its partners continue to refine this technology, it holds the promise of connecting underserved and remote regions, thereby enhancing emergency response capabilities and ensuring that users remain connected regardless of their location. However, the widespread adoption of this technology will require substantial investment in satellite infrastructure and careful coordination with existing terrestrial networks to ensure seamless service delivery.

What Does This Mean For Your Business?

Vodafone’s successful satellite-enabled video call marks a significant step towards a future where mobile connectivity is no longer restricted by geography. By demonstrating that a standard smartphone can make a video call via satellite without additional hardware, Vodafone has shown the potential to bridge the long-standing gaps in mobile coverage. For those living in or travelling through remote areas, this could mean reliable access to communication services where traditional networks have struggled to reach. In emergency situations, where connectivity can be a matter of life and death, the ability to make calls and access the internet via satellite could prove invaluable.

However, while the achievement is impressive, there are still challenges to overcome before this technology becomes widely available. Issues with connection quality, including latency and bandwidth limitations, need to be addressed to ensure a seamless user experience. Regulatory approvals and the logistical task of deploying enough satellites to provide consistent coverage remain significant hurdles. Vodafone’s timeline for a full commercial rollout, set for later in 2025 and 2026, suggests that further development and testing are required before the service can be reliably offered to the public.

There are also broader concerns to consider. The expansion of satellite connectivity raises questions about its impact on the night sky, with astronomers warning that an increasing number of satellites could interfere with space observations. Others have questioned whether eliminating mobile ‘not-spots’ entirely is beneficial, as some value the ability to disconnect in remote locations. The issue of cost is another key factor, as Vodafone has yet to confirm how much customers will need to pay to access the service. If pricing is too high, the benefits of satellite connectivity may be limited to specific industries or wealthier consumers rather than the wider public.

Despite these challenges, Vodafone’s innovation signals a shift in how mobile connectivity is delivered. Rather than replacing existing terrestrial networks, this technology is likely to act as a complementary solution, ensuring coverage in places where it has previously been unfeasible. For Vodafone, it cements its position as a leader in mobile network evolution, following on from its historic role in launching the UK’s first mobile call 40 years ago. For the wider industry, it sets a precedent that other telecoms providers will inevitably follow, as companies explore ways to integrate satellite connectivity into their networks.

This breakthrough is essentially a glimpse into the future of mobile communications. While it is not yet a complete solution, it has the potential to reshape the way people stay connected, providing mobile broadband access to areas that have long been left behind. If Vodafone and its partners can overcome the technical and regulatory obstacles, satellite-to-smartphone connectivity could redefine what it means to be online, anytime, anywhere.
