What is the reason for shifting from c band to ku band in satellite communication?
A
Lesser attenuation
B
Less power requirements
C
More bandwidth
D
Overcrowding
Explanation: 

Detailed explanation-1: -6. What is the reason for shifting from c band to ku band in satellite communication? Explanation: Most new communication satellites will operate in the Ku band. This upward shift in frequency is happening because the C band is overcrowded.

Detailed explanation-2: -These are some of the advantages of choosing Ku-band: because of their 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.

Detailed explanation-3: -Ku-band satellite antennas are smaller than C-band antennas, but they are susceptible to rain fade during heavy rainfall (their signals can be affected by rain absorption). Ku-band is commonly used for broadcast and VSAT (Very Small Aperture Terminal) systems on ships and vessels.

Detailed explanation-4: -The major differences between the Ku-band and the C-band receive-only systems lies in the frequency of operation of the outdoor unit and the fact that satellites intended for DBS have much higher EIRP. This consists of a low noise amplifer/converter combination.

Detailed explanation-5: -C Band Frequencies are from 4 to 8 GHz. Ku Band Frequencies are from 12 to 18 GHz. Beyond that KU-band requires a much smaller antenna and is less susceptible to variations in weather and interference cause by the leaves of trees and other tresterial interferences.

Detailed explanation-6: -The presence of rain can have a significant detrimental effect on the propagation of an electromagnetic signal. The rain degradation increases as the frequency increases. At C-band (6/4 GHz), rain has little effect, except for brief periods of unusually heavy rain, but at Ku-band (14/12 GHz) it can be important.

Detailed explanation-7: -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.
