United States Frequency Allocations The Radio Spectrum Chart
The radio frequency spectrum is a range of electromagnetic waves that are used for communication purposes. It is divided into various frequency bands that are used for different communication purposes. The United States Federal Communications Commission (FCC) is responsible for managing the radio frequency spectrum in the United States. The FCC has allocated different frequency bands for different communication services.
Radio Frequency Spectrum
The radio frequency spectrum is a range of electromagnetic waves that are used for communication purposes. It is divided into various frequency bands that are used for different communication purposes. The radio frequency spectrum is divided into different frequency bands such as VLF, LF, MF, HF, VHF, UHF, L, S, C, X, Ku, K, Ka, and Q.
Frequency Allocation
The FCC is responsible for managing the radio frequency spectrum in the United States. The FCC has allocated different frequency bands for different communication services. The frequency bands are allocated based on the type of communication service, the required bandwidth, and the propagation characteristics of the frequency band.
Frequency Bands
The frequency bands are divided into different categories such as low frequency, medium frequency, high frequency, very high frequency, ultra-high frequency, super high frequency, and extremely high frequency. Each category has different frequency bands allocated for different communication services.
Low Frequency
The low frequency band ranges from 30 kHz to 300 kHz. This frequency band is used for communication with submarines and for navigation purposes.
Medium Frequency
The medium frequency band ranges from 300 kHz to 3 MHz. This frequency band is used for AM radio broadcasting and aviation communication.
High Frequency
The high frequency band ranges from 3 MHz to 30 MHz. This frequency band is used for international broadcasting, amateur radio, and maritime communication.
Very High Frequency
The very high frequency band ranges from 30 MHz to 300 MHz. This frequency band is used for FM radio broadcasting, television broadcasting, and mobile communication.
Ultra-High Frequency
The ultra-high frequency band ranges from 300 MHz to 3 GHz. This frequency band is used for radar, satellite communication, and microwave ovens.
Super High Frequency
The super high frequency band ranges from 3 GHz to 30 GHz. This frequency band is used for satellite communication, GPS, and wireless communication.
Extremely High Frequency
The extremely high frequency band ranges from 30 GHz to 300 GHz. This frequency band is used for research purposes and for military communication.
Conclusion
The United States frequency allocations the radio spectrum chart is an important document that outlines the different frequency bands allocated for different communication services in the United States. The radio frequency spectrum is divided into various frequency bands that are used for different communication purposes. The FCC is responsible for managing the radio frequency spectrum in the United States and has allocated different frequency bands for different communication services based on the type of communication service, the required bandwidth, and the propagation characteristics of the frequency band.
