due to path loss : higher is the frequency higher is the patrh loss

Define downlink frequency?
In the sense of a mobile communication: Downlink frequency is that used by a base station to communicate with the Mobile. In satellite communication also the same theory exists downlink is the return path.
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.
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 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 is the frequency range in satellite communication?
The satellite transponder typically works in either the C-band (4-8GHz) or the Ku-band (12-18GHz) and these are for the downlink (from the satellite to the earth station).
What describes a signal with a frequency of 20GHz in a satellite radio transmissions?
A downlink signal; a Ka Band signal
What describes a signal with a frequency of 20 GHz in satellite radio transmissions?
A downlink signal A Ka Band signal
Where you can get the frequency of bharathtv?
here is the satellite & frequency details of Bhaarath TV ================================================================ SATELLITE: Insat 2E at 83°E DOWNLINK FREQ: 4042 POLARISATION : Vertical SYMBOL RATE: 8000 FEC: 7/8
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
Schematic diagram of uplink and downlink?
uplink frequency-1710-1785MHz downlink frequency-1805-1880
Why is satellite communication not widely used for mobile communication.?
In satellite communication uplink (transmission of signal from earth station to satellite ) & downlink (reception of signal from satellite to earth station) takes place TX & RX involves a finite amount of delay which is acceptable in data communication, but i audio & video TX this delay is unacceptable, overlapping/ alaising causes errors which demodulated by qpsk.
What is the transmission from a satellite to an earth-based station?
downlink
