What is the uplink frequency of Ku band in GHz?
14/11 gigahertz
6/4 gigahertz, or in the Ku band, in which uplink/downlink frequencies are in the range of 14/11 gigahertz. These frequency bands have been selected to exploit spectral “windows,” or regions within the microwave band in which there is low atmospheric attenuation and low external noise.
What is the frequency range of Ku band?
12–18 GHz
Ku-band (12–18 GHz)
What is uplink and downlink frequency?
Uplink frequency is the frequency at which, the first earth station is communicating with satellite. The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.
What is 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. Some companies sell uplink and downlink services to television stations, corporations, and to other telecommunication carriers.
Why Ku band is used for the DBS service?
Advantages of Ku-band because of their higher power, Ku band satellites (vary in size from 2′ to 5′ in diameter) are generally smaller than C band satellites. the power of uplinks and downlinks can be increased as needed. users with a C-band system in place can retrofit for Ku-band use.
What are the uplink and downlink frequencies in C-band transponder?
Use in satellite communication Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks.
How do you calculate uplink and downlink frequency?
The actual frequencies (uplink and downlink) used inside the frequency range are determined by the ARFCN….Frequency Bands.
| GSM 850 | T-GSM810 | |
|---|---|---|
| ARFCN | 128 through 251 | 350-425 |
| Uplink (UL) Formula (MHz) | FUL(n) = 824.2 + 0.2*(n-128) | FUL(n) = 806 + .2*(n-350) |
| Downlink (DL) Formula (MHz) | FDL(n) = FUL(n)+45 | FDL(n) = FUL(n)+45 |
