Satellite frequency bands
- L-band (1–2 GHz) Global Positioning System (GPS) carriers and also satellite mobile phones, such as Iridium; Inmarsat providing communications at sea, land and air; WorldSpace satellite radio.
- C-band (4–8 GHz)
- X-band (8–12 GHz)
- Ku-band (12–18 GHz)
- Ka-band (26–40 GHz)
Subsequently, one may also ask, what are bands in satellite?
The “band” in use refers to the radio frequencies used to and from the satellite: L-band uses frequencies in the 1 to 2GHz range. Ku-band utilises approximately 12-18GHz, and. Ka-band services uses the 26.5-40GHz segment of the electromagnetic spectrum.
One may also ask, why is satellite communication done in GHz frequency range? All GPS signals are in the L-band of the frequency spectrum ( 1–2 GHz). Because L-band waves penetrate clouds, fog, rain, storms, and vegetation, GPS units can receive accurate data in all weather conditions, day or night.
Likewise, people ask, what are the different types of frequency bands?
Frequencies as designated by the International Telecommunications Union
- 3 Hz-30 Hz. Wavelength: 10^8m-10^7m. Band: Extremely low frequency (ELF)
- 30 Hz-300 Hz. Wavelength: 10^7m-10^6m. Band: Super low frequency (SLF)
- 300 Hz-3 KHz. Wavelength: 10^6m-10^5m. Band: Ultra low frequency (ULF)
- 300 Hz-3 KHz. Wavelength: 10^6m-10^5m.
Why is high frequency used in satellite communication?
The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points.

Which bands Cannot be used for satellite communication?
7. Which of the following bands cannot be used for satellite communication? Explanation: MF is a lower frequency band than Ku, C and X bands and does not lie in the microwave spectrum. Microwaves are used for satellite communication since the lower bands get reflected by the ionosphere.What is the typical bandwidth of a satellite band?

The downlink frequency is the frequency which is used for transmission of signals from the satellite to the earth station receiver. The satellite transmitter generates a signal that would jam its own receiver; if both uplink and downlink shared the same frequency.What is the uplink frequency of satellite?
When frequency increases, wavelength decreases. The larger the wavelength, the bigger the antenna (satellite dish) necessary to receive it. The two bands used most frequently are the C-band and the Ku-band. The C-band has an uplink frequency of 6 GHz and a downlink frequency of 4 GHz.What frequency is K band?
The IEEE K band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27 gigahertz (GHz).

A frequency band is a range of frequencies. They're usually referred to by the wavelength (e.g. 40 meters is the band from 7000 KHz to 7300 KHz). A frequency is the reference point for tuning your transceiver.What is bandwidth frequency?
Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies. It is typically measured in hertz, and depending on context, may specifically refer to passband bandwidth or baseband bandwidth.What is high frequency and low frequency?
Low-frequency sounds are 500 Hz or lower while high-frequency waves are above 2000 Hz. Human ears can register sounds from about 20 Hz in frequency up to 20,000 Hz, depending of course, upon the hearer. People with hearing loss usually have trouble hearing sounds in the higher frequency range.What is meant by frequency?

It say basically the power at ground stations is more as compared to power available at satellites.So generally frequency for uplink is kept higher than the downlink. There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency.How do I figure out frequency?
Divide the wavelength into the velocity to calculate the frequency, expressed as described above as the number of cycles per second, or Hertz – written "Hz."

GSM-900 and GSM-1800 are used in most of the world. 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.How many satellites are in space?
Right now, there are nearly 6,000 satellites circling our tiny planet. About 60% of those are defunct satellites—space junk—and roughly 40% are operational. As highlighted in the chart above, The Union of Concerned Scientists (UCS), determined that 2,666 operational satellites circled the globe in April of 2020.What is the importance of satellite?
Satellites provide in-flight phone communications on airplanes, and are often the main conduit of voice communication for rural areas and areas where phone lines are damaged after a disaster. Satellites also provide the primary timing source for cell phones and pagers.What is the difference between uplink and downlink?
Communications SystemThe communication going from a satellite to ground is called downlink, and when it is going from ground to a satellite it is called uplink. When an uplink is being received by the spacecraft at the same time a downlink is being received by Earth, the communication is called two-way.
