Every information sent and received through satellite communication has to have an address to enable the communication process of signal delivery and reception. This naming of the signal is made in the form of a specific frequency. For example each TV channel operates on a unique frequency of it's own. When that frequency is called (tuned technically) out of a spectrum in that band, the chosen frequency gets selected.
Since satellite transponders operate at very high frequency, modulation of the signal on to the carrier is difficult. Hence modulation is carried out at a much lower frequency. Such modulated signal is raised to the required frequency( name or address as stated above) that supports the satellite band and the transponder. The equipment used to elevate the frequency of the low frequency carrier (known as Intermediate Frequency) to the satellite transponder frequency is UP CONVERTER

What is the definition of 'optical satellite communication'?
definition of optical satellite communication
What is first communication satellite?
The first communication satellite was Echo NASA
What is the receiving and transmitting device called that is inside a communication or broadcast satellite that relays received signals back to Earth?
downlink
What are telecommunication links?
In satellite communication, up link refers to the signal traveling up to the satellite while down link refers to the signal coming from the satellite down to earth.
What is a communications satellite?
Satellite communication is when a signal gets sent to space, bounces off of a satellite, and comes back to Earth. This is a very common source of communication.
How satellite communication is different from communication relay?
For communication satellites the range is much higher than that of communication relay. Communication Satellite can cover up to several thousands of kilometers. For communication relay, the uplink and the downlink frequency is the same. But for communication satellites the uplink and the downlink frequencies are different in order to avoid interference.
Why Fresnel zone affecting satellite communication?
