The Ku and C-bands are the portions of the electromagnetic spectrum in the microwave range of frequencies that are used for long-distance radio telecommunications.
Ku-band (12-18 Gigahertz) is primarily used in satellite communications such as fixed and broadcast services. It is also used for backhauls and particularly for satellite from remote locations back to a television network’s studio for editing and broadcasting. The band is split into multiple segments that vary by geographical region by the International Telecommunication Union (ITU).
C-band (4-8 Gigahertz) are used for many satellite communications transmissions, some Wi-Fi devices, cordless telephones, and some weather radar systems. For satellite communications, the microwave frequencies of the C-band perform better under adverse weather conditions in comparison with Ku band.
For India, both these bands are of immense importance as it intends to augment its satellites capacity to meet the growing demands of communication services and fulfil the dream of Digital India by delivering Information Technology and Communication services in every household.
