What is the frequency used for satellite communication?
Satellite Communication (satcom) is based on a specific range of frequencies. The useable radio spectrum ranges from 1Ghz to 300Ghz, where its use for communications ends as the signal becomes infrared, X-Ray and visible light. For maritime satcom, we use the frequencies from 1Ghz up to approx. 30Ghz.
How many frequency bands are there?
Pursuant to convention, the ITU divides the radio spectrum into 12 bands (as shown in the table below), each beginning at a wavelength which is a power of ten (10n) metres, with corresponding frequency of 3×108−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name.
Which frequency range is used in radar communication?
The remote sensing radars are concentrated in the region between 9 and 10 GHz and around 14 to 16 GHz. Satellite communications use bands near 4 and 6 GHz and between 11 and 13 GHz as well as some higher frequencies.
Which waves are used in satellite communication?
Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light).
What is K band frequency?
The IEEE K band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27 gigahertz (GHz). The range of frequencies in the center of the K band between 18 and 26.5 GHz is absorbed by water vapor in the atmosphere due to its resonance peak at 22.24 GHz, 1.35 cm.
Which type of electromagnetic waves is used in radar?
Radar uses radio waves which are electromagnetic waves and travel at a speed of 300,000,000 m/s.
What are satellite frequency bands?
The most popular frequency bands available on satellite are L band, S band, C band, X band, Ku band, k band and Ka bands. C band Satellite will usually will have 5.925 to 6.425 GHz frequency range in the uplink and 3.7 to 4.2 GHz frequency range in the downlink.
What are satellite bands?
Satellite is a Polish progressive rock band. It was founded in 2000 by college drummer Wojtek Szadkowski as a quartet, with Sarhan Kubeisi on guitar, Robert Amirian as vocalist and bassist, and Krzysiek Palczewski on keyboards. Their debut album, A Street Between Sunrise And Sunset, was released on March 10,…
What frequency is B band?
The B band is an uncommon frequency allocation term for the US market. B-band is a term used by the European Union, NATO and the US ECM for the frequency range from 250 to 500 MHz. The US FCC frequency allocation for this range is VHF (30 to 300 MHZ) and UHF (300 to 1000 MHz).
What is the frequency range of C band?
C-band covers from 3.7 to 8 GHz, however the frequency range for satellite television is from 3.7 to 4.2 GHz. Used mostly for commercial satellite television transmissions, C-band is becoming less of a residential option.
