uplink frequency-1710-1785MHz downlink frequency-1805-1880
Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.
Uplink --> 890 MHz - 915 MHz Downlink --> 935 MHz - 960 MHz
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.

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
In the CDMA technology It is either between your Handset and the Mobile Station. The dedicated frequency are allocated for u sending your data to the mobile station (Uplink freuency) and a dedicated frequency is reserved for you to receive your data from the mobile station (Downlink frequency)
Worldwide downlink for voice - 145.80Worldwide packet uplink/downlink - 145.825Region 1 voice uplink - 145.20Region 2 and 3 voice uplink - 144.49Worldwide uplink for cross band voice repeater - 437.80Worldwide SSTV downlink - 145.800For more information, visit the NASA ISS Amateur Radio page at http://spaceflight.nasa.gov/station/reference/radio/
due to path loss : higher is the frequency higher is the patrh loss
Most two-way radios are 'duplex' transceivers. This means they transmit (uplink)on one frequency and receive (downlink) on another- spaced at least 13 MHz apart. This stops interference between the radio's components.
Tetra communication systems typically operate within the frequency range of 380-400 MHz for uplink and 390-410 MHz for downlink transmissions.
Uplink is from MS to BS Downlink is from BS to MS P.S: BS=Base Station, MS=Mobile Station e.g cell phone
