| Frequency range | ITU band |
|---|---|
| 30-300 MHz | VHF (Very High Frequency) |
| 300 MHz -3 GHz | UHF (Ultra High Frequency) |
| 3-30 GHz | SHF (Super High Frequency) |
What are the specific bands assigned by the ITU for the radar what the corresponding frequencies?
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz)….IEEE radar bands.
| Band designation | Frequency range | Explanation of meaning of letters |
|---|---|---|
| VHF | 0.03 to 0.3 GHz | Very High Frequency |
| UHF | 0.3 to 1 GHz | Ultra High Frequency |
| L | 1 to 2 GHz | Long wave |
| S | 2 to 4 GHz | Short wave |
What is frequency band used for?
It is commonly used in point to point communication, satellite systems, digital TV broadcasting in Ku band (DTH service – direct to home), Wi-Fi (5GHz channel), microwave ovens and mobile networks. Waveguides are suitable between transmitter and antenna due to higher losses of usual RF cables.
What does ITU mean?
International Telecommunication Union
Agency of the United Nations, headquartered in Geneva. The ITU is the body through which governments and the private sector coordinate global telecommunications networks and services.
What band is 500 MHz?
NATO B band
The NATO B band is the obsolete designation given to the radio frequencies from 250 to 500 MHz (equivalent to wavelengths between 1.20 and 0.60 m) during the cold war period.
What is the application of high frequency that range from 3 30 MHz?
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz. Much of the HF band is allocated to mobile and fixed voice communication services requiring transmission bandwidths of less than 12 kilohertz. International (shortwave radio) broadcasting…
What are the different frequency bands present and name the applications for each band?
Satellite frequency bands
- L-band (1–2 GHz) Global Positioning System (GPS) carriers and also satellite mobile phones, such as Iridium; Inmarsat providing communications at sea, land and air; WorldSpace satellite radio.
- C-band (4–8 GHz)
- X-band (8–12 GHz)
- Ku-band (12–18 GHz)
- Ka-band (26–40 GHz)
What is 300 MHz used for?
They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones,, satellite phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.
What is V band frequency?
The V band (“vee-band”) is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz).
What are ITU standards?
The International Telecommunication Union (ITU) is the United Nations agency for information and communication technologies – ICTs. It allocates global radio spectrum and satellite orbits and develops technical standards that ensure networks and technologies seamlessly interconnect.
What is the frequency range of the band band?
Band [kHz] Region 1 Region 2 Region 3 NA 525-526.5 NA A NA 526.5-535 535-1605 A 1 A 2 A 1 1605-1606.5 A 1 A 1 1605.5-1705
What frequency bands are included in the frequency allotment and assignment plans?
Overview of frequency allotment and assignment Plans Appendix 25 to RR Planned bands: exclusive maritime between 4 000 kHz and 27 500 kHz Modifications to the Plan: Appendix 25 Special Sections (published in BR IFIC)
What are ITU-R recommendations?
The worldwide technical standards (ITU-R Recommendations) are developed within the six Study Groups of ITU-R, which gather experts drawn from government, industry, academia, and regional and international organizations, who collaborate in establishing the characteristics of the systems and services that will define tomorrow’s wireless landscape.
What do you use ITU for?
Every time you turn on your radio or television, hop on a plane, call home on your mobile phone, access the Internet or find your location with your smartphone, tablet or personal computer, every time you watch the weather forecast or view satellite images of the Earth, you are using one of the vital services coordinated by ITU worldwide.
