![]() ![]() It’s because lower frequencies get reflected by atmospheric bands and cannot penetrate to get through to the satellite. ![]() Why is there a gap between uplink and downlink frequencies? The output of a coding chain is a codeword. It has a structure very similar to the downlink shared channel, with CRC, code block segmentation, the use of LDPC, a key difference with LTE, and rate matching. The uplink shared channel, or UL-SCH, is the channel that carries user data. Some companies sell uplink and downlink services to television stations, corporations, and to other telecommunication carriers. In 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. The 5G cellular network of the mid-range bands around 3.5GHz is based on Time Division Duplex (TDD) mode, which means that base stations and end-user devices transmit using the same channel at different times, while the lower-bands of 5G NR (including 700MHz, 1.8GHz and 2.1GHz) are based on Frequency Division Duplex ( … What is the difference between uplink and downlink? Often it is the speed of the downlink (from the network to the device) that determines a good time-to-content, as many popular apps receive more data in downlink than they send in uplink. For example, the edge switch connects “up” to the distribution layer managed switch. The uplink port is used to connect a device to other higher-speed ones in the topology or smaller local network to a larger network. It is a telecommunications link for signals coming to the earth from a satellite, spacecraft, or aircraft. The downlink is a term used in radio communications and satellite communications to denote the link from the network to the end user or from the satellite to the earth.
