AT&T's successful test of a phone call on a regular cellular device between Texas and Japan via a low-orbit satellite has raised the possibility of a future with widespread satellite coverage and reduced reliance on traditional cell towers. The call was made on a BlueWalker3 satellite, which traveled on a low-orbit path.
AT&T's Successful Test of Satellite-Based Phone Call Raises Possibility of Widespread Coverage. AT&T's successful test of a phone call on a regular cellular device between Texas and Japan via a low-orbit satellite has raised the possibility of a future with widespread satellite coverage and reduced reliance on traditional cell towers.
The call was made on a BlueWalker3 satellite, which traveled on a low-orbit path.
The call, which lasted for several minutes and was of good quality, was made between AT&T's labs in Plano, Texas, and its office in Tokyo, Japan.
While AT&T has termed the test a proof of concept, it is still working on developing the technology for commercial use.
If AT&T succeeds in developing the technology, it could revolutionize the telecommunications industry.
Satellite-based cellular technology could be used to provide coverage to areas that are currently underserved by traditional cell towers, such as rural areas and developing countries.
Additionally, satellites could be used as a backup coverage in the event of natural disasters or other emergencies.
The development of satellite-based cellular technology is still in its nascent stages, but its potential impact cannot be overstated.
AT&T's success could mean a future where cell towers are not necessary everywhere.
