Frequencies Ku, Ka, C. - three standouts among satellite frequency bands. Get your network "swinging" with the right one.
Ku band provides the best overall combination of available bandwidth, high-power transponders, and lack of terrestrial interference to support broadband applications into small antennas.
The VSAT illustrated below provides high data rate transmissions between a remote site and a hub, using Ku band satellites like Horizons-1 and Horizons-2.
- Throughput of 10 Mbps received by the VSAT and up to 2 Mbps transmit.
- Service availability with this equipment and satellites would be 99.9%
While susceptible to rain fade (interference from rain), reliability can remain strong with proper engineering. C band

C band services are among the most reliable because the frequency is less susceptible to rain attenuation. C-band, however, is susceptible to terrestrial interference which can often be mitigated with proper engineering and planning. Applications:
Ka band and Other
Ka band is useful for medium data rate service to small terminals; however, availability is generally lower than at Ku band due to greater effects from rain.
There are a few Ka band satellites in operation for North America - Spaceway and Telesat F2. Service is limited and capacity is not made available to the general user community.
