The Blue Walker 3 satellite, which has been orbiting Earth for a year, recently achieved a significant milestone by establishing its first 5G connection. This breakthrough occurred when the satellite initiated a phone call to an ordinary smartphone in a cellular dead zone. The mobile user, situated in Hawaii, was able to converse with an engineer in Spain through the satellite’s connection for nearly two minutes. Abel Avellan, the CEO of AST SpaceMobile, the company behind Blue Walker 3, expressed enthusiasm for this achievement, stating that it represents a groundbreaking shift in access to information.
Furthermore, subsequent tests of the Blue Walker 3 satellite demonstrated its capability to attain download speeds of 14 megabits per second. Satellites with such high-speed capabilities have the potential to revolutionize various aspects of communication, including faster internet browsing, rapid file downloads, streaming video applications, and more. Avellan also highlighted that Blue Walker 3 now offers full compatibility with smartphones from major manufacturers, supporting not only 5G but also 2G and 4G LTE connections.
This advancement is part of a broader initiative to deploy more advanced satellites in space. Plans are underway to construct a total of 100 similar satellites, which will be larger and more adept at establishing advanced 5G connections. Many key players in the space industry are harnessing Low Earth Orbit (LEO) satellites to provide affordable 5G connectivity services over extensive areas.
Operating in Low Earth Orbit does present some challenges when it comes to achieving widespread 5G connectivity. While LEO satellites enable transmission through standard cellular radios, their range is limited, restricting the portion of the Earth they can cover. In contrast, geosynchronous satellites orbit much farther away and can encompass a significantly larger percentage of the Earth’s surface. This makes them more suitable for supporting numerous devices and delivering a robust 5G connection.
Currently, there are several geosynchronous satellites in orbit, including those used for weather monitoring and data transmission by organizations like NASA. However, it is estimated that it may take about a decade for the space industry to fully develop geosynchronous satellites optimized for 5G connectivity.
Brian Lavallée, Senior Director of Ciena, commented on the potential of future 5G connectivity, suggesting that it will eventually enable seamless connectivity. In areas with coverage, mobile phones will continue to utilize traditional cell towers, but as satellite technology advances, it will play a crucial role in expanding and enhancing global connectivity options.
