Which is best C-band or Ku band?
Ku-band is preferred for cases where there is a limited area for installation, because a smaller dish size is needed and it is easy to install. From a commercial point of view, Ku-band is better for satellite applications that need smaller bandwidth, as the equipment is cheaper than C-band.
What is the difference between C-band and Ku band?
The Ku band frequency range is 11.7 – 12.2 GHz (or 11700 to 12220 MHz) Notice how these frequencies are higher than the C band frequency range. Because of the higher frequencies, Ku band waves have shorter wavelengths. Shorter wavelengths mean that you need a smaller dish to receive these frequencies.
Which band is used in VSAT?
VSATs are generally distinguished from the other types of earth stations by the use of smaller antenna apertures, which are nonetheless capable of operating with closely spaced satellites. They are most often designed to operate in the 6/4 GHz, 14/11-12 GHz and 30/20 GHz frequency bands.
What are the advantages of Ku band over C-band transmission?
Advantages of Ku-band because of its higher power, Ku band satellites (vary in size from 2′ to 5′ in diameter) are generally smaller than C band satellites. the power of uplinks and downlinks can be increased as needed. users with a C-band system in place can retrofit for Ku-band use.
Are C band satellites still used?
C-band is currently used for the “satellite downlink” for broadcast television distribution.
What is the range for C band and Ku band?
satellite communications …to operate in the so-called C band, which employs uplink/downlink frequencies of 6/4 gigahertz, or in the Ku band, in which uplink/downlink frequencies are in the range of 14/11 gigahertz.
What is Ku-band used for?
The Ku band is mainly used for satellite communications, especially downlink, used by direct-transmission satellites for satellite television and specific applications such as the NASA’s Tracking Data Relay Satellite used for both the space shuttle and for communications from the International Space Station (ISS).
What is C-band used for?
The C band is used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones as well as some surveillance and weather radar systems.
Why C band is widely used in satellite communication?
C-band refers to the portion of the electromagnetic spectrum allotted for satellite transmissions in the 4GHz to 8GHz frequency range. C-band satellite antennas are used frequently in areas of the world where signals can become degraded due to heavy rain or other intense climate-related conditions.
What is Ku band used for?
What is Ku band antenna?
Ku-band satellite antennas (which are smaller than C-band antennas but suffer from rain fade in monsoon-like downpours) are typically used in Europe and North America.
What is the difference between Ku band and C Band VSAT?
The frequency band 12.5 GHz to 18 GHz is referred as Ku Band. The VSAT which operates in this band is known as Ku Band VSAT. Following frequencies are used in uplink and downlink in Ku band VSAT. The frequency band 4 to 8 GHz is referred as C Band. The VSAT which operates in this band is known as C Band VSAT.
Why Ku-band for VSAT?
Due to higher power levels at new satellites Ku-band allows for significantly smaller earth station antennas and RF units to be installed at the VSAT location. At the inception of satellite communications in Africa, C-band was the only option.
What is a C band antenna?
The C band is primarily used for voice and data communications as well as backhauling. Because of its weaker power it requires a larger antenna, usually above 1.8m (6ft).
Which frequency band is better for VSAT communication?
The two main bands for VSAT communications are C-Band & Ku-Band. The question is which of them is better and when to use each of them? Here you will find a C band Ku band Comparison. C-Band & Ku-Band have their pros & cons. We will discuss the pros and cons of the two frequency bands here to provide a clear idea of each one’s suitable use.
