A video call to space may change mobile coverage forever

Global telecommunications company Vodafone has successfully tested a “space video call” using a standard mobile phone and commercial satellites. It’s an important step towards eliminating mobile coverage black spots, and the carrier hopes to offer the first commercial direct-to-smartphone broadband satellite service in the U.K. later this year, and elsewhere in Europe sometime in 2026. To get here, however, various obstacles must be overcome.

In recent years, companies like Apple, Samsung, and T-Mobile have begun offering satellite communication capabilities for smartphones and smartwatches. However, this feature is limited to specific devices and is intended for emergency use only. More importantly, it only allows users to send text messages to emergency services in areas without cellular or Wi-Fi coverage.

Vodafone is working to offer a complete mobile broadband experience for anyone without cellular or Wi-Fi coverage. Its first successful test came through a video call from a mountain in Ceredigion, west Wales. The team didn’t call the International Space Station though. Instead, Vodafone’s call, made in an area without any coverage, connected to a satellite which then sent it down to the terrestrial network, ready to connect to another device. The video below shows the call itself.

As Vodafone CEO Margherita Della Valle explains, this service could eliminate “not spots,” sometimes called “blackspots,” where there’s currently no coverage.

“It’s a really important moment because we are opening the door to universal connectivity, to connecting people in the U.K., wherever they are,” she said.

The British-based Vodafone partnered with satellite company AST SpaceMobile to do the test.

Despite the company’s claims, Vodafone’s successful test doesn’t necessarily mean it will be available to consumers this year.

As the BBC explains, Vodafone must overcome key regulatory issues before it can proceed. Additionally, astronomers warn the increasing number of satellites in orbit that might be required for direct-to-smartphone broadband satellite service could make it harder to study space.

There’s also the question of price. To date, Vodafone has not mentioned what this type of service will cost. Typically, satellite communication can be expensive, making it cost-prohibitive to some users.

Other obstacles have less to do with regulations and costs. For example, satellite connections typically have higher latency and lower bandwidth than terrestrial networks, affecting video call quality. Additionally, weather conditions can affect satellite signals, potentially disrupting video calls.

Satellite-enabled smartphone video calls have immense potential to revolutionize communication, provided that any existing obstacles can be addressed. One of the most significant advantages is the ability to bridge the digital divide, ultimately giving everyone access to the internet. This increased connectivity could promote social inclusion, stimulate economic development, and improve access to essential services such as education and healthcare.

Additionally, these capabilities would enable travelers, explorers, and researchers in remote areas to stay connected with family, colleagues, and emergency services, enhancing their safety and peace of mind. Satellite-enabled smartphone video calls could facilitate better real-time communication in emergencies or disasters. They would allow for the transmission of visual information about the situation on the ground, helping emergency responders make informed decisions and allocate resources effectively.

Vodafone isn’t the only company trying to perfect satellite video communication. In the U.S. T-Mobile is testing a satellite service along the same lines as Vodafone’s, while Apple introduced a satellite messaging feature with the iPhone 14, and MediaTek parterned with Motorola and the (now defunct) Bullitt Group to make the Defy Satellite Link dongle designed for emergency use.
