![]() Its uplink frequency is 145.990 MHz, and its downlink frequency is 437.800 MHz. The International Space Station (ISS) is now equipped with a mode V/U repeater. These satellites are said to be operating in mode U/V. i think in C-band if the uplinking frequency. The difference between a radio channel’s uplink (transmit) and downlink (receive) frequencies is known as the frequency offset. Some satellites have an uplink frequency in the 70 cm band and a downlink frequency in the 2 m band. The satellite transponder converts this signal into another. The frequency ranges and channel arrangements, as well as the formulas that describe the actual frequency of the ARFCN, are detailed in the 3GPP TS 45.005 Version 5.9.0 Release 5 (with the exception of the T-GSM810 band) and the tables below. if i have the downlink frequecy of some channel ,is it possible to calculate the uplink Frequency of that channel. Uplink frequency is the frequency at which, the first earth station is communicating with satellite. The downlink frequency is the frequency which is used for transmission of signals from the satellite to the earth station receiver. An uplink in computer networking refers to a wired or wireless connection from a local area network (LAN) to a wide area network (WAN). The actual frequencies (uplink and downlink) used inside the frequency range are determined by the ARFCN. In this paper, we study the sensitivity of uplink and downlink MC-DS-CDMA to carrier frequency offsets, assuming orthogonal spreading sequences. The uplink frequency is the frequency which is used for transmission of signals from earth station transmitter to the satellite. A cell's frequency band determines which frequency range the test set uses to communicate with a mobile station.
