Uplinking refers to the transmission of a signal via a satellite from one terrestrial location to another location and then ultimately the signal can be distributed to the end users.
What is the role of uplinking in the entertainment sector?
In broadcasting, broadcasters use uplinking to beam their programmes to their viewers across countries. Typically, they hire the services of a transponder or a transponder itself that will be used to beam the broadcaster's programmes to the receiving country.
What is the Indian policy on uplinking?
Till some time ago, there were restrictions on uplinking from India. In July 2000, the government liberalised uplinking and allowed Indian companies to set up their own teleports to uplink directly from India. Television channels were also allowed uplinking facilities. The foreign equity holding of such companies should not exceed 49%.
The frequency of uplinking varies from user to user according to band assigned. Many upling frequency is 4mhz in c band and 10 mhz in ku band
Generally uplinking and downlinking frequencies are kept different in order to minimise interference and distortion.

to all, Uplink on a certain satellite differs from each satellites. For example if you are advised to uplink on a Satellite ( example Intelsat 910 or PAS 10) you will be advised on what transponder center frequency you will occupy. Its the job of the Satellite frequency operator to issue you a certain frequency normally ranging 5.925 to 6.425 GHz for C-Band and KU-Band ranges from 14. to 14.5 GHZ. Also the bandwith of the carrier will be an issue in which the sat operator taken into consideration before giving you your uplink frequency. With the help of this Satellite Operators, we can prevent someone's carrier stepping on someone's carrier on the satellite which can cause interruption of the service.

Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.
12-14ghz
GSM 900: Uplink frequency: 890 - 915 MHz GSM 1800 : Uplink frequency: 1710 - 1785 MHz GSM 1900: Uplink frequency: 1850 - 1910 MHz
due to path loss : higher is the frequency higher is the patrh loss
Uplink and downlink are frequencies Communication from earth station to satellite in uplink and communication from satellite to earth station is downlink Always uplink freq.>downlink freq.
You would need to know the LO frequency from the satellite. Ex- C-band is 2200Mhz If you UL is 6.0GHz you DL would be 3.8GHz
uplink frequency-1710-1785MHz downlink frequency-1805-1880
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.
1800mhz
repair modulator encoder dishes
Uplink --> 890 MHz - 915 MHz Downlink --> 935 MHz - 960 MHz
To avoid interference
