The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering , the frequency range of the X band is set at approximately 7.0–11.2 GHz .
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
x Band Satellite Communication operates in the part of the X band or Super High Frequency (SHF) spectrum which is designated by the International Telecommunication Union (ITU) for satellite communication, which is those frequencies in the range 7.25 GHz to 7.75 GHz (Space to Earth) and 7.9 GHz to 8.4 GHz (Earth to Space).

The Enhanced Position Location Reporting System (EPLRS) is a secure, jam-resistant, computer-controlled communications network that distributes near real-time tactical information, generally integrated into radio sets, and coordinated by a Network Control Station. [1] It is primarily used for data distribution, position location, and reporting.
Radio frequencies and their primary mode of propagation Band Frequency Wavelength Propagation via ELF: Extremely Low Frequency 3–30 Hz: 100,000–10,000 km Guided between the Earth and the D layer of the ionosphere. SLF: Super Low Frequency 30–300 Hz: 10,000–1,000 km Guided between the Earth and the ionosphere. ULF: Ultra Low Frequency 0. ...
The X-Band and S-Band radar has different characteristics and detection capabilities compared with each other. [1] Most merchant ships carry at least one of each type to ensure adequate target detection and response. [ 1 ]
In radio-frequency engineering and communications engineering, a waveguide is a hollow metal pipe used to carry radio waves. [1] This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave ...
In ITU Radio Regulations, the range 275 – 3,000 GHz whilst not formally allocated, is subject to footnote 5.565; this was last revised by WRC-12 and the current version is below: 5.565 The following frequency bands in the range 275-1,000 GHz are identified for use by administrations for passive service applications: Radio astronomy service:
