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 .
Read moreWhy downlink data rate is higher than uplink?
The allowable pathloss for Downlink is more compared to that of the Uplink. (Because UE TX power is limited and NodeB power is much higher ). Hence the data rate in the downlink is higher compared to that in the uplink.
Read moreWhat is the meaning of uplink and downlink?
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 .
Read moreWhy is uplink and downlink frequency different?
Since a mobile station (cellphone) cannot afford to transmit at high power to compensate for this loss, it must transmit on a lower frequency as a lower frequency presents lesser free space path loss. Therefore, mobile-to-base station (uplink) frequencies are lower than base station-to-mobile(downlink) frequencies.
Read moreWhat is meant by uplink?
Definition of uplink 1 : a communications channel for transmissions to a spacecraft or satellite also : the transmissions themselves. 2 : a facility on earth for transmitting to a spacecraft or satellite.
Read moreWhy uplink and downlink frequency are not same in satellite?
It’s because lower frequencies get reflected by atmospheric bands and cannot penetrate to get through to the satellite . … Therefore, mobile-to-base station (uplink) frequencies are lower than base station-to-mobile(downlink) frequencies.
Read moreHow is network frequency calculated?
Mathematically, Frequency = f = c/λ . The frequency is expressed in “per second” or “Hertz”, abbreviated as Hz. In real life networks, the frequency is expressed in Megahertz (MHz) or Gigahertz (GHz).
