WebThe frequency with which, the signal is sent into the space is called as Uplink frequency. Similarly, the frequency with which, the signal is sent by the transponder is called as Downlink frequency. The following figure illustrates this concept clearly. WebIntroduction. 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. For example Band-1 and Band-4 can have same Rx frequency 2110-2170 MHz, but …

EARFCN formula- Huawei

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception. The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process called heterodyning, resulting in … See more Intermediate frequencies are used for three general reasons. At very high (gigahertz) frequencies, signal processing circuitry performs poorly. Active devices such as transistors cannot deliver much amplification ( See more An intermediate frequency was first used in the superheterodyne radio receiver, invented by American scientist Major Edwin Armstrong in … See more • Mechanical filter • Low-IF receiver • Zero-IF receiver See more Perhaps the most commonly used intermediate frequencies for broadcast receivers are around 455 kHz for AM receivers and 10.7 MHz for FM receivers.

Satellite link budget calculator

WebIn satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite. Some companies sell uplink and downlink services to television stations, corporations, and to other telecommunication carriers. WebIt is possible to extrapolate the cumulative attenuation distribution at a given location by using the CCIR interpolation formula: [4] Ap = A001 0.12 p− (0.546 − 0.0043 log10 p). where Ap is the attenuation in dB exceeded for a p percentage of the time and A001 is the attenuation exceeded for 0.01% of the time.
