What are the commonly used frequency bands for VSAT communication?

C-band is characterized by larger antennas and is preferred by a variety of full-time service providers.C-band ("compromise" band) is a portion of electromagnetic spectrum in the microwave range of frequencies ranging from4 to6 GHz -- normally downlink3.7–4.2 GHz, uplink5.9–6.4 GHz.Ku-band services generally use smaller antennas and have become more common for home use. The Ku-band ("kay-yoo" kurz-under band) frequencies ranging from to GHz.The new Ka-band frequencies represent the leading edge for advanced services. The Ka band (kurz-above band) ranges from to GHz.
