Why must a satellite have distinct uplink and downlink frequencies?
To avoid interference
What is satellite transponder?
It is an electronic device on board a geostat satellite to receive uplink data and picture bits,amplifying it before converting it to a downlink freqency bit stream and sending it down to earth.
What is uplink frequency in gsm?
GSM 900: Uplink frequency: 890 - 915 MHz GSM 1800 : Uplink frequency: 1710 - 1785 MHz GSM 1900: Uplink frequency: 1850 - 1910 MHz
What is uplink?
Uplink translates also to Upload - where you send data to another destination.
Schematic diagram of uplink and downlink?
uplink frequency-1710-1785MHz downlink frequency-1805-1880
What is uplink and downlink?
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.
What is uplink frequency?
Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.
What are the frequency ranges satellite uplink?
12-14ghz
Why must a satellite have distinct uplink and downlink frequencies?
To avoid interference
What is a creation of a communications channel for a transmission from an earth based transmitter to an orbiting satellite?
uplink
What is an earth to satellite connection?
It's an uplink. You must do the same crossword that I do! It's in today's.
What is satellite uplink?
The uplink is the transmitter than sends the data up to the satellite. This can take the form of a dish or a highly directional antenna. You typically see these directional antennas mounted on telescoping poles mounted on the top of TV station news vans.
Who is slower satellite uplinks or downlinks?
downlink becouse frequncy / power low compare to uplink
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.
What is satellite transponder?
It is an electronic device on board a geostat satellite to receive uplink data and picture bits,amplifying it before converting it to a downlink freqency bit stream and sending it down to earth.
Why uplink frequency is kept higher than downlink freqquency in satellite communication?
due to path loss : higher is the frequency higher is the patrh loss
How do you calculate downlink frequency by uplink?
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
