On September 24, the world's first satellite-based 5G call was successfully dialed in Europe, jointly implemented by AST Space Mobile's satellite and telecom operator Vodafone. In addition, this test also achieved a data transmission rate of 14Mbps.
This 5G phone call was implemented using the BlueWalker3 test satellite, which was jointly built by Vodafone, AT&T, and Nokia. It used a chip designed by the British company EnSilica.
This 5G call was made from Maui, Hawaii, to a Vodafone engineer in Madrid, Spain. It used the spectrum provided by AT&T in the United States through the BlueWalker3 satellite. The mobile phone used to make the call was an original Samsung Galaxy S22. The test broke the previous data transmission speed record for space-based cellular mobile networks, achieving a download rate of 14Mbps.
Abel Avellan, CEO of AST Space Mobile, said, "This achievement represents another major technological progress we have made and marks a change in the way we obtain information." Since the launch of the BlueWalker3 satellite, the company has successfully achieved compatibility with all major mobile phone manufacturers and supports 2G, 4G LTE, and 5G networks.
Tommi Uitto, President of Nokia Mobile Networks, expressed congratulations. He said that space-based cellular mobile networks can provide important network connections around the world. He is proud of the key role played by Nokia's AirScale product portfolio in this network.
It is understood that ASTSpaceMobile has more than 2,600 technology patents, some of which are being applied for. The company has built a state-of-the-art research and development facility in Texas, USA.
