We are moving closer to a world where carriers can fill gaps in their 5G coverage by using signals from space (echo effect: space…space…space). This morning, AT&T and AST SpaceMobile announced the successful completion of a call placed from Maui, Hawaii, to a Vodafone engineer in Madrid, Spain. The call was made on September 8th using AT&T spectrum and AST SpaceMobile’s BlueWalker 3 test satellite using an unmodified Galaxy S22 handset in an area considered a “wireless dead zone.”
