Satellite internet (Viasat, HughesNet, Starlink) provides universal coverage as a last-resort option for addresses outside wired broadband service areas. Low-Earth-orbit (LEO) satellite from Starlink has improved latency to 20-60 ms, a significant improvement over geostationary services (600+ ms), making it a practical alternative for rural households without viable fixed-line options.
