In a groundbreaking achievement that marks a pivotal moment in the world of telecommunications, Vodafone and AST SpaceMobile recently completed the world’s first space-based 5G voice call using a standard smartphone. This technological leap has far-reaching implications, potentially bringing high-speed internet and mobile connectivity to the remotest regions on Earth.

The Space-Based 5G Call: A Remarkable Feat

The successful space-based 5G voice call, which originated in Hawaii and connected a Vodafone engineer in Spain using an unmodified Samsung Galaxy S22 smartphone, is a testament to the relentless pursuit of innovation in the telecommunications industry. This achievement was made possible through AST SpaceMobile’s BlueWalker 3 test satellite, the largest commercial communications array ever deployed in low Earth orbit.

This historic call represents a groundbreaking moment in space-based communication technology, pushing the boundaries of what was previously thought possible. Notably, it showcases the seamless integration of cutting-edge 5G technology with space-based infrastructure, ushering in a new era of connectivity.

Closing the Digital Divide: A Global Imperative

One of the most significant implications of this achievement is its potential to bridge the digital divide that persists in many parts of the world. Vodafone’s CEO, Margherita Della Valle, emphasised their commitment to closing the mobile usage gap, particularly in underserved regions of Europe and Africa. Space-based 5G technology can play a pivotal role in realising this ambition.

In remote and rural areas where traditional terrestrial networks are economically unviable, space-based 5G communication can provide a lifeline to communities by offering access to the internet, educational resources, telemedicine services, and economic opportunities. By leveraging existing mobile phones, millions of people who were previously disconnected can now be part of the digital age.

AST SpaceMobile’s Ambitious Goals

AST SpaceMobile, the driving force behind this technological breakthrough, has set ambitious goals for the future. The successful space-based 5G call is just the beginning of their journey. The company plans to launch five commercial BlueBird satellites in the first quarter of 2024. These satellites will further enhance the capabilities of space-based communication, making high-speed internet and mobile connectivity more accessible globally.

The expansion of space-based infrastructure goes beyond voice calls and basic connectivity. The achievement of nearly 14 Mbps in download speeds during a space-based cellular broadband data session record demonstrates the potential for high-speed data communication. This has far-reaching implications for industries such as telemedicine, remote work, and IoT applications that rely on seamless data transmission.

A Glimpse into the Future

Looking ahead, Vodafone and AST SpaceMobile’s collaboration promises even more exciting developments. Vodafone’s engineers are actively testing AST SpaceMobile’s services in Spain, intending to establish a robust satellite network infrastructure. This includes the management of customer traffic and extending coverage to remote land-based areas within Europe and the Mediterranean Sea.

Furthermore, Vodafone and Vodacom are exploring the use of Low Earth Orbit (LEO) satellites to connect geographically dispersed cellular antennas back to their core telecom networks. This approach holds the potential to enhance network coverage and connectivity in regions that have long struggled with connectivity challenges.

The successful space-based 5G call between Vodafone and AST SpaceMobile marks a significant milestone in the world of telecommunications. It represents a giant leap towards closing the global digital divide, offering the promise of connectivity and opportunity to even the most remote corners of our planet. With ambitious plans on the horizon and the relentless pursuit of innovation, the future of space-based 5G communication appears brighter than ever, heralding a new era of connectivity for all.
