satellite communications
Orbiting relay links
Satellite communications refers to the transmission and reception of signals using artificial satellites orbiting Earth as relay stations.
This technology enables television broadcasts, telephone calls, internet service, and data transfer across vast distances where ground-based infrastructure is impractical or unavailable.
Rural areas often depend on satellite communications for internet access.
The term encompasses both the equipment involved and the broader industry of space-based telecommunications.
