Which frequency band to choose: C, Ku, Ka or L

Which solution to choose depends today from commercial and less from technical factors, as no matter what frequency band used – both technologies supply internet services at acceptable quality.

L-Band (1-2 GHz) being a relatively low frequency, L-band is easier to process, requiring less sophisticated and less expensive RF equipment, and due to a wider beam width, the pointing accuracy of the antenna does not have to be as accurate as the higher bands.

Commercially it is fact that hardware for C-Band is significantly more expensive while the capacity is cheaper. So customers with large bandwith requirements preferably choose this technology.

Ku-Band on the other hand operates with smaller antennas and less expensive equipment, while the capacity price is higher than C-Band.

Ka-band provides increased spectrum compared to C-band and Ku-band, enabling greater volumes of traffic to be transmitted. Many industries are looking to Ka-band because the smaller end-user antennas (VSATs), increased mobility and higher bandwidths and speeds make the benefits of Ka-band satellite capacity an attractive offering.
