What is meant by downlink and uplink?
Uplink and downlink, also called upload and download, refers to the two-way communication between a cell tower and your phone. Downlink definition – signal coming from a cell tower to your cellular device. Uplink definition – signal leaving your cellular device and going back to a cell tower.
What is uplink and downlink data rate?
Data rate is basically the rate at which data is transferred from one place to the other through wired or wireless medium….Typical Data rate of wireless technologies.
| Wireless Technology | Downlink Data Rate(Mbps) | Uplink Data Rate(Mbps) |
|---|---|---|
| WCDMA R99 | 0.384 | 0.384 |
| HSPA | 14.4 | 5.76 |
What does an uplink transmit?
Pertaining to radiocommunication service, an uplink (UL or U/L) is the portion of a feeder link used for the transmission of signals from an earth station to a space radio station, space radio system or high altitude platform station.
What is a satellite uplink and its purpose?
A transmission is sent from a station on Earth to the satellite. This signal is called an uplink. The satellite, in orbit about the Earth, receives the signal and then transmits it back to earth stations. This transmission signal back to earth is called a downlink.
What 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.
What means uplink?
What is meant by downlink?
In satellite communications, downlink simply refers to the process when a satellite beams down information toward earthbound terminals or devices. The opposite of this is uplink, where the satellite receives data from an earthbound terminal.
Why uplink is higher than downlink?
In satellite communication, the uplink frequency is higher than the downlink frequency because the attenuation level increase with an increase in frequency. The power at the ground station (Base Station) is more than compared to the power available at the satellite.
What is uplink and downlink in GSM?
GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (BTS) (This is the “uplink”) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels spaced at 200 kHz. Duplex spacing is 95 MHz.
What is uplink with example?
In satellite communication, uplink means that data are being passed from any earthbound terminal or device up towards the satellite. For example when sending a text message, the phone creates an uplink with the base station in order to send the text message. The inverse is receiving a text message through a downlink.
