Satellite frequency band spectrum. With the variety of satellite frequency bands that can be used designations have been developed so that they can be referred to easily. Vhf band vhf band is the frequency spectrum between 30 and 300 mhz. While they didn t pay for the spectrum the companies that now use the c band spectrum and their various predecessors invested billions in satellites ground stations and other technology to. The russians have often used the hf bands at 21 and 29 mhz for amateur communications.
Operation is the frequency range 10700 mhz to 12650 mhz. There are a number of radio frequency ranges in use in satellite communications such as c x ku ka and even ehg and v band. Secondary use of terrestrial spectrum by a satellite system. The plan calls for the fcc to pay satellite companies 3 billion to 5 billion in compensation for abandoning the so called c band spectrum and moving to another frequency so the airwaves can be.
Satellite operators said at satellite 2019 that the 28 ghz spectrum band is one they need to defend more diligently. Different frequency bands are suitable for different climate conditions types of service and types of users. Choose a centre frequency and span that fits within this range. 7 and is given as secondary use of satellite spectrum by a terrestrial system.
Certain frequency bands have been dedicated for satellite use for many decades by the body responsible for managing the radio spectrum the international telecommunications union. To prevent interferance caused by multiple sites transmitting on the same frequencies government agencies and standards organizations around the globe try to keep the usage organized and often such controls take the form of government regulations which carry the weight. The division is an updated list from höyhtyä et al. It covers the broadcast television channels 2 54 mhz to 13 216 mhz and cable tv channels 2 54 mhz to 36 300 mhz.
The upper end frequencies are attenuated as the lnb is operating beyond its design range. The most popular bands for these satellites are the 144 146 and 435 438 mhz bands. The higher frequency bands typically give access to wider bandwidths but are also more susceptible to signal degradation due to rain fade the absorption of radio signals by atmospheric rain snow or ice. Frequency sharing in satellite bands can be divided into four main categories.
