Satellite services for telecommunications
The telecommunications sector is the largest customer segment in the satellite industry by revenue, consuming satellite capacity for infrastructure services that underpin terrestrial and mobile networks. Telecom satellite customers include mobile network operators (MNOs) using satellite backhaul, DTH broadcast platform operators, fixed-line ISPs purchasing wholesale satellite bandwidth, and submarine cable operators using satellite as a diverse backup route.
Cellular backhaul
In emerging markets — sub-Saharan Africa, South and Southeast Asia, rural Latin America — satellite backhaul connects mobile base stations in villages and towns where terrestrial fibre or microwave is uneconomical. A single Ka-band HTS or LEO satellite link can provide 20–100 Mbps per base station, enabling 4G/LTE services for communities of thousands of rural mobile subscribers at total connectivity costs competitive with alternative terrestrial options. MTN, Airtel, Bharti, and Viettel are major operators using satellite cellular backhaul.
DTH broadcasting infrastructure
Direct-to-home broadcasting platforms (Sky, Canal+, DIRECTV, DISH) are major GEO transponder lessees, maintaining multi-year contracts for C-band and Ku-band capacity to distribute hundreds of TV channels to millions of satellite dish subscribers. The broadcasting vertical has been disrupted by IP streaming (Netflix, Disney+, etc.) reducing DTH subscriber counts in developed markets — but remains the dominant TV delivery mechanism in emerging markets where streaming infrastructure is insufficient.
