NATO C band
The NATO C band is that portion of the electromagnetic spectrum between 500 MHz and 1000 MHz. Provision No 21 of the ITU Radio Regulations states 21 The Radio spectrum shall be subdivided into nine frequency bands which Very low frequency or VLF refers to radio frequencies (RF in the range of 3 KHz to 30 KHz. Low Frequency or LF refers to Radio Frequencies (RF in the range of 30 kHz&ndash300 kHz Medium frequency ( MF) refers to radio frequencies (RF in the range of 300 kHz to 3000 kHz High frequency (HF radio frequencies are between 3 and 30 MHz. Very high frequency (VHF is the Radio frequency range from 30 MHz to 300 MHz. Super high frequency (or SHF) refers to radio frequencies (RF in the range of 3 GHz and 30 GHz Extremely high frequency is the highest Radio frequency band.

Super high frequency (or SHF) refers to radio frequencies (RF in the range of 3 GHz and 30 GHz Extremely high frequency is the highest Radio frequency band. Radio waves are electromagnetic waves occurring on the Radio frequency portion of the Electromagnetic spectrum. This is article is about the wireless term For other uses see A band (disambiguation. The B band is the range of radio frequencies from 250 MHz to 500 MHz in the Electromagnetic spectrum. D band is the range of radio frequencies from 1 GHz to 2 GHz in the Electromagnetic spectrum. The NATO E band is the range of radio frequencies from 2 GHz to 3 GHz in the Electromagnetic spectrum. The F band is the range of radio frequencies from 3 GHz to 4 GHz in the Electromagnetic spectrum. NATO G band The G band in the modern (NATO/EU sense is the range of radio frequencies from 4 GHz to 6 GHz in the Electromagnetic The H band is the range of radio frequencies from 6 GHz to 8 GHz in the Electromagnetic spectrum. The I band is the range of radio frequencies from 8 GHz to 10 GHz in the Electromagnetic spectrum. The J band is the range of radio frequencies from 10 GHz to 20 GHz in the Electromagnetic spectrum. NATO K band The NATO K band is defined as a frequency band between 20 and 40 GHz (7 NATO L band The NATO L band is defined as the frequency band between 40 and 60 G[[Hertz Hz]] (5–7 The M band is the range of radio frequencies from 60 GHz to 100 GHz in the Electromagnetic spectrum. Radio waves are electromagnetic waves occurring on the Radio frequency portion of the Electromagnetic spectrum. High frequency (HF radio frequencies are between 3 and 30 MHz. Very high frequency (VHF is the Radio frequency range from 30 MHz to 300 MHz. NATO L band The NATO L band is defined as the frequency band between 40 and 60 G[[Hertz Hz]] (5–7 The S band ranges from 2 to 4 GHz, crossing the (artificial boundary between UHF and SHF at 3 The X band is part of the Microwave region of the Electromagnetic spectrum. The Ku band ( pronounced "kay-yoo") is a portion of the Electromagnetic spectrum in the Microwave range of frequencies NATO K band The NATO K band is defined as a frequency band between 20 and 40 GHz (7 The Ka band (Pronounced "Kay-A Band" covers the frequencies of 26 The V band (vee-band of the Electromagnetic spectrum ranges from 40 to 75 GHz The W band of the Microwave part of the Electromagnetic spectrum ranges from 75 to 111 GHz. The electromagnetic (EM spectrum is the range of all possible Electromagnetic radiation frequencies The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second.
IEEE C band
The IEEE C band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4 to 8 GHz. The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international Non-profit, professional organization Microwaves are electromagnetic waves with Wavelengths ranging from 1 mm to 1 m or frequencies between 0 [1].
It was the first frequency band allocated for commercial ground-to-satellite communications. A typical C band satellite uses 3. 7–4. 2 GHz for downlink, and 5. The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. Uplink An uplink (UL or U/L is the portion of a communications link used for the transmission of signals from an Earth terminal 925–6. 425 GHz for uplink. Uplink An uplink (UL or U/L is the portion of a communications link used for the transmission of signals from an Earth terminal C band is primarily used for open satellite communications, whether for full-time satellite TV networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct broadcast satellite, which is a completely closed system used to deliver subscription programming to small satellite dishes connected to proprietary receiving equipment. Direct broadcast satellite (DBS is a term used to refer to Satellite television broadcasts intended for home reception also referred to more broadly as direct-to-home
C band is highly associated with TVRO satellite reception systems, commonly called "big dish" systems since small receiving antennas are not optimal for C-band systems. Television receive-only, or TVRO is a term used in North America to refer to the reception of Satellite television from FSS -type satellites Typical antenna sizes on C-band capable systems ranges from 7. 5 to 12 feet (2. 5 to 3. 5 meters) on consumer satellite dishes, although larger ones also can be used.
The 5. 4GHz band (5. 15–5. 35/5. 47–5. 725/5. 725–5. 875 GHz) is used for IEEE 802. 11a WIFI and cordless phone applications, leading to occasional interference with C band weather radars.
C band variants
Slight variations of C band frequencies are approved for use in various parts of the world.
