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.
Hi, For every GSM band there are Uplink and downlink frequencies. Example: GSM 900 TX: 880 MHz to 915 MHz is an uplink frequency range GSM 900 RX: 925 MHz to 960 MHz is a downlink frequency range Aloha, Maverick
Uplink is from MS to BS Downlink is from BS to MS P.S: BS=Base Station, MS=Mobile Station e.g cell phone
As the frequency increase its penetration power decreases.The signal travels a lesser distance.Hence for a perticular area more no of towers need to be erected in 1800/1900 than in 900MHZ for full coverage...Hence vodafone( 1800MHZ) has more towers per unit area than Idea Cellular ( 1800+900) ..... Band of 900 is from 890-915( uplink) 935-960Mhz( downlink).... Band of 1800 is from 1710-1785(uplink) and 1805-1880MHZ(Downlink).... Same property is followed here.....The uplink is lower ( MOBILE -BTS) than the downlink frequency (BTS-MOBILE)...so that this may help the uplink signal to travel futher without consuming much power...BTS due to its increased power ,has higher frequency to tavel the same distance....

Which can cause auroras and disrupt satellite transmission?
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.
Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.
12-14ghz
repair modulator encoder dishes
To avoid interference
uplink
It's an uplink. You must do the same crossword that I do! It's in today's.
downlink becouse frequncy / power low compare to uplink
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.
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.
due to path loss : higher is the frequency higher is the patrh loss
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
