C-Band VS KU-BandThe selection for suitable operating frequency depends on such factors as size and gain of antenna, bandwidth allocation, atmospheric attenuation or losses, various sources of noise, different types of loss and noise point of view, the C-Band can provide high-quality transmission and is used exclusively by commercial satellite communication. However there is an increasing usage of this band in large urban areas because they also constitute the frequencies used for terrestrial microwave links. Thus a severe drawback of the C-Band is that of "The problem of interference between satellite link and terrestrial microwave links". By far the most serious interference is that from an earth station interfering with a microwave receiver nearby. This is because an earth station must transmit high power signal to make up the large transmission distance loss. Some of the signal spilled may therefore be substantial to interfere with a microwave receiver, hence an earth station should not be located in large urban areas.
