and geostationary orbit satellites into a framework
that can operate as standalone networks or be
integrated with terrestrial 5G services. The result is a
network that combines ground and space, ensuring
service continuity and reinforcing resilience. NTNs are
promising for direct-to-device (D2D) communications
in which smartphones and IoT devices connect without
relying on terrestrial cell towers.
There are compromises. High frequencies, including
the Ka and Ku bands used by the latest systems,
offer greater throughput but are affected by
atmospheric conditions. Lower frequencies provide
better penetration but offer lower data rates.
Summary
Satellite communications are integral to the future
of global connectivity. As LEO constellations
expand and AESA technology matures in commercial
applications, SATCOM will create resilient networks
beyond the reach of traditional, ground-
based infrastructure.

With low-cost LEO satellites,
you're looking at smaller, lighter
designs with three- to six-year
lifespans, making it possible
to launch many at once, unlike
traditional GEO satellites
that typically require one
payload per launch."
