The S band ranges from 2 to 4 GHz, crossing the imaginary boundary between UHF and SHF at 3. 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.

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. C band is a name given to certain portions of the Electromagnetic spectrum, as well as a range of Wavelengths of Light, used for communications 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 C band is a name given to certain portions of the Electromagnetic spectrum, as well as a range of Wavelengths of Light, used for communications 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 hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. Super high frequency (or SHF) refers to radio frequencies (RF in the range of 3 GHz and 30 GHz 0 GHz. It is part of the microwave band of the electromagnetic spectrum. Microwaves are electromagnetic waves with Wavelengths ranging from 1 mm to 1 m or frequencies between 0 The electromagnetic (EM spectrum is the range of all possible Electromagnetic radiation frequencies The S band is used by weather radar and some communications satellites, especially those used by NASA to communicate with the Space Shuttle and the International Space Station. A weather radar is a type of Radar used to locate precipitation, calculate its motion estimate its type ( Rain A communications satellite (sometimes abbreviated to comsat) is an artificial Satellite stationed in space for the purposes of Telecommunications. The National Aeronautics and Space Administration ( NASA, ˈnæsə is an agency of the United States government, responsible for the nation's public space program NASA 's Space Shuttle, officially called the Space Transportation System ( STS) is the Spacecraft currently used by the United States The 10-cm radar short-band ranges roughly from 1. A centimetre ( American spelling: centimeter, symbol cm) is a unit of Length in the Metric system, equal to one hundredth Radar is a system that uses electromagnetic waves to identify the range altitude direction or speed of both moving and fixed objects such as Aircraft, ships 55 to 5. 2 GHz. The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second.
S band is also used in optical communications to refer to the wavelength range from 7. Optical communication is any form of Telecommunication that uses Light as the transmission medium 5cm to 15cm.
In the U.S., the FCC approved Digital Audio Radio Satellite (DARS) broadcasts in the S band from 2. The United States of America —commonly referred to as the Digital Audio Radio Service or DARS refers to any type of digital radio service For the band see Broadcast (band Broadcasting is the distribution of audio and/or Video signals which transmit 310 to 2. 360 GHz, currently used by Sirius Satellite Radio and XM Satellite Radio.
In some countries, S band is used for Direct-to-Home satellite television (unlike similar services in most countries, which use Ku band). 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 The Ku band ( pronounced "kay-yoo") is a portion of the Electromagnetic spectrum in the Microwave range of frequencies The frequency typically allocated for this service is 2. 5 to 2. 7 GHz (LOF 1. 570 GHz).
More recently, the FCC has approved for portions of the S band between 2. 0 and 2. 2 GHz the creation of Mobile Satellite Services (MSS) networks in connection with Ancillary Terrestrial Components (ATC). There are presently a number of companies attempting to deploy such networks, including ICO Satellite Management and TerreStar. ICO Global Communications (Holdings Limited is a mobile satellite services company based in Reston Virginia. TerreStar Networks is a Reston Virginia -based company that operates integrated Satellite and terrestrial Telecommunications systems
Wireless network equipment compatible with IEEE 802.11b and 802.11g standards use the 2. The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international Non-profit, professional organization IEEE 80211b-1999 or 80211b, is an amendment to the IEEE 80211 specification that extended throughput to up to 11 Mbit/s using the same 2 IEEE 80211g-2003 or 80211g, is an amendment to the IEEE 80211 specification that extended throughput to up to 54 Mbit/s using the same 2 4GHz section of the S band. Also IEEE 802.16a and 802. The IEEE 80216 Working Group on Broadband Wireless Access Standards, which was established by IEEE Standards Board in 1999 aims to prepare formal specifications 16e standards utilize a part of the frequency range of S-Band, under WiMAX standards most vendors are now manufacturing equipment in the range of 3. WiMAX, an approximate acronym of Worldwide Interoperability for Microwave Access, is a Telecommunications technology that provides for the wireless transmission 5GHz. The exact frequency range allocated for this type of use varies between countries.
