C-Band VSAT — Superior Availability in All Climates

C-Band VSAT at 3.7–4.2 GHz offers the best link availability of all VSAT frequency bands. Its large wavelength makes it virtually immune to rain fade, which is critical in tropical regions across Africa, Southeast Asia, and Latin America. GCCSAT C-Band solutions are favoured for government networks, broadcast backbones, and remote enterprise sites where 99.9%+ uptime is mandatory.

Frequently Asked Questions

C-Band offers the highest link availability — typically 99.9% or better — because its longer wavelength is less affected by rain. This makes it ideal for Africa, South Asia, and other tropical regions where Ka-Band and Ku-Band experience significant rain fade outages.

C-Band antennas are larger (1.8m–3.7m) due to the longer wavelength, making them less suitable for maritime or mobile applications. They require more installation space and structural support than Ka-Band or Ku-Band systems.

Yes. GCCSAT provides C-Band VSAT across all 54 African countries through partnerships with regional satellite operators. C-Band is the recommended option for sub-Saharan Africa where monsoon rains significantly impact higher frequency bands.

C-Band VSAT typically delivers 1–20 Mbps for enterprise customers, though dedicated (CIR) circuits at higher speeds are available. C-Band is optimised for reliability over throughput, making it ideal for backup links and mission-critical applications.
