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.
frequency modulation, preferably.
A technique called frequency reuse allows satellites to communicate with a number of ground stations using the same frequency, by transmitting in narrow beams pointed toward each of the stations. Beam widths can be adjusted to cover areas - footprints - as large as the entire United States or as small as a state like Maryland. Two stations far enough apart can receive different messages transmitted on the same frequency. Satellite antennas have been designed to transmit several beams in different directions, using the same reflector.
satellite is satellite
Answer: 1.communication satellite 2.navigational satellite 3.weather satellite 4.millitary satellite 5.scientific satellite 6.satellite launches. It composed of 6 satellites...........i hope.....my answer can help you.....
Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.
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
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 bandGenerally uplinking and downlinking frequencies are kept different in order to minimise interference and distortion.For details mail meSanidhyagenioushunk@gmail.com

The uplink frequency is higher than the downlink frequency in satellite communication because higher frequencies can carry more information and are less affected by interference and noise. This setup allows for efficient communication between ground stations and satellites, ensuring a reliable transmission of data.
