Satellite Direct-to-Device Technology Aims to Eliminate Mobile Dead Zones by 2029

The mobile “dead zone” could soon be a relic of the past as satellites prepare to connect directly to standard smartphones, according to Space42. The UAE space technology company is currently developing direct-to-device technology engineered to keep regular, unmodified phones connected when users move beyond the reach of traditional mobile networks.

Viktor Stoyanov, chief operating officer of Smart Solutions at Space42, stated that the technology will offer connectivity in remote regions where 4G and 5G networks fail, such as at sea, in deserts, and across mountainous terrain. “In the near future, you'll be able to connect to the satellites and receive connectivity even if you're deep in the ocean, deep in the desert, high in the mountains,” he informed reporters at the company's headquarters in Abu Dhabi. The overarching goal is for the switch between terrestrial and satellite networks to be virtually imperceptible to the user.

Recently, Space42 and Viasat committed $1 billion to Equatys, a joint venture tasked with building a global direct-to-device satellite network, with commercial services slated to launch in 2029. This initiative expands upon a partnership announced last year aimed at eliminating communication black spots.

This innovative technology forms part of a broader strategy by Space42 to leverage satellites for comprehensive connectivity and earth observation. Its Foresight constellation is also capable of producing radar imagery featuring resolutions of up to 25cm. The Foresight constellation currently consists of five synthetic aperture radar, or SAR, satellites.

“What this means is you can capture an object that is the size of 25cm or larger and correctly visualise it on an image,” Mr Stoyanov explained. Unlike conventional optical satellites, SAR operates independently of sunlight, utilizing radar signals to capture imagery through challenging environmental conditions like cloud cover, smoke, and dust. Mr Stoyanov likened the capability to an “X-ray image of the Earth”.

Abdullah Sharif, senior manager of the Foresight Constellation at Space42, characterized the capacity to observe what standard optical satellites miss as a “superpower”. He presented SAR imagery of an explosion site where heavy smoke had blocked an optical satellite, noting that the radar image successfully enabled the location and assessment of damage on the ground.

Additionally, Space42 is pairing repeated observations with artificial intelligence to identify changes over time. Mr Sharif noted that integrating AI with sequential images of the same location transforms Foresight into a “change detection machine”. Christos Kolimenakis, chief executive of ICEYE UAE, which partners with Space42 on the Foresight programme, added that comparing successive images can successfully uncover underlying patterns.

Three of the five Foresight satellites currently in orbit underwent assembly, integration, and testing directly within the UAE. Furthermore, Space42 manages its own mission ground segment, while its downstream analytics and AI models are developed domestically. “Sovereignty is the key here for Space42,” Mr Sharif emphasized. “The UAE today is controlling its eye.”

For everyday consumers, however, direct-to-device connectivity will likely deliver the most apparent transformation. Nermeen Negm, vice president of communications at Space42, likened the intended user experience to a smartphone transitioning smoothly from home Wi-Fi to a cellular network. By the end of the decade, she suggested, people will look back at mobile dead zones much like they view life prior to the existence of Wi-Fi or Google Maps.
