In a FDD system one ARFCN number is required for downlink and another for uplink as downlink and uplink frequencies are different while for TDD system only one ARFCN number is enough as downlink and uplink frequency remains same.3 Tem 2018
Read moreWhat is uplink and downlink frequency in satellite communication?
Uplink frequency is the frequency at which, the first earth station is communicating with satellite . The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.
Read moreWhy uplink and downlink frequencies are different in satellite communication?
It say basically the power at ground stations is more as compared to power available at satellites .So generally frequency for uplink is kept higher than the downlink. There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency.
Read moreWhat is meant by downlink?
: to transmit (data) from a spacecraft or satellite to a receiver on earth .
Read moreWhat is DL frequency?
In case of FDD (Frequency Division Duplex) LTE downlink channel (DL, eNB transmits UEs receive) and uplink channel (UL, UEs transmit eNB receives) are transmitted simultaneously on different frequencies. Also each band is marked by LTE release number where it was defined.

EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number .In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.
