Why in mobile communication is the uplink frequency lower than the downlink frequency?

To enable two-way conversations to take place simultaneously. If you use a single frequency, one person has to wait until the other has finished speaking before they can respond. With split frequencies, both people can speak and hear simultaneously - without waiting for the other to stop speaking. It's technical term is 'split frequency duplex'.

Schematic diagram of uplink and downlink?
uplink frequency-1710-1785MHz downlink frequency-1805-1880
What is the uplink and downlink frequency in 2100 band?
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)
Why must a satellite have distinct uplink and downlink frequencies?
To avoid interference
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
Why does GSM use separate channels for Uplink and Downlink?
So that they can both be used at the same time (i.e. full duplex) without interference.
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 is the Uplink and downlink frequency for GSM900?
Uplink --> 890 MHz - 915 MHz Downlink --> 935 MHz - 960 MHz
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.
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
What is an uplink an downlink in mobile coommunication?
Uplink is from MS to BS Downlink is from BS to MS P.S: BS=Base Station, MS=Mobile Station e.g cell phone
Why uplink frequency is greater than downlink frequency can you provide me these details with technical data?

What is gsm uplink?
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
Why gsm 880 mhz to 915 mhz is known as downlink frequency?
This is actually the EGSM uplink band. It carries signals "up" from the mobile station to the base station. EGSM downlink is from 925MHz to 960MHz and carries signals from the base station "down" to the mobile station.
What is the radio frequency numbers for the ISS station?
