On the basis of the requirements expressed by each country, assignment plans allocate frequencies for each station in a given service ; allotment plans grant to each country frequencies intended for use by a given service, frequencies which the country then assigns to the stations within its jurisdiction according to …
Read moreHow are allocated frequencies?
ITU definition The International Telecommunication Union defines frequency allocation as being of “a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions “.
Read moreHow is spectrum divided?
The spectrum is divided into different frequency bands, each having a specific application . For instance, the frequency band that covers 300 kHz to 535 kHz is reserved for aeronautical and maritime communications and the spectrum from 535 kHz and 1705 kHz for AM radio. This process is called “allocation”.
Read moreWhat is frequency channel spacing?
Channel spacing, also known as bandwidth, is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan .
Read moreWhat frequencies are used in space?
Radio frequency communications for spacecraft are conducted between 30 MHz and 60 GHz . The lower frequency bands are typically more mature for SmallSat usage, however extensive use of these bands has led to crowding and challenges acquiring licensing.

According to wireless testing firm Rohde and Schwarz, the C-band is all frequencies between 4 and 8GHz . When US wireless geeks talk about C-band, though, they’re talking about 3.7 to 4.2GHz—and specifically, in this case, the range from 3.7 to 3.98GHz.
