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 hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. [1][2] It is used by some communications satellites, and for some terrestrial Eureka 147 digital audio broadcasting (DAB). A communications satellite (sometimes abbreviated to comsat) is an artificial Satellite stationed in space for the purposes of Telecommunications. Radio is the transmission of signals by Modulation of electromagnetic waves with frequencies below those of visible Light. Digital Audio Broadcasting ( DAB) also known as Eureka 147, is a Digital radio technology for Broadcasting Radio stations used in Digital Audio Broadcasting ( DAB) also known as Eureka 147, is a Digital radio technology for Broadcasting Radio stations used in The amateur radio service also has an allocation between 1240 and 1300 MHz. Amateur radio, often called ham radio, is both a Hobby and a service in which participants called "hams" use various types of Radio communications The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. The L Band refers to the frequency range of 950 MHz to 1450 MHz. It is the result of the downconversion of the received downlink satellite signals (C or Ku) by the LNB (Low Noise Block converter).
Military use
In the United States and overseas territories, the L band is held by the military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC) solutions. The United States of America —commonly referred to as the United States territory is any extent of Region under the Jurisdiction of the federal Government of the United States, including all The United States Armed Forces are the overall unified military forces of the United States Telemetry (synonymous with Telematics) is a Technology that allows the remote measurement and reporting of Information of interest to the system designer Digital radio describes Radio technologies which carry Information as a Digital signal, by means of a Digital modulation method In-band on-channel ( IBOC) is a method of transmitting Digital radio and Analog radio broadcast signals simultaneously on DAB is typically done in the 1452–1492-MHz range as in most of the world, but other countries also use VHF and UHF bands. Digital Audio Broadcasting ( DAB) also known as Eureka 147, is a Digital radio technology for Broadcasting Radio stations used in The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. Very high frequency (VHF is the Radio frequency range from 30 MHz to 300 MHz.
GNSS
The Global Positioning System carriers are in the L band, centered at 1176. Basic concept of GPS operation A GPS receiver calculates its position by carefully timing the signals sent by the constellation of GPS Satellites high above the Earth In Telecommunications, a carrier wave, or carrier is a Waveform (usually Sinusoidal) that is modulated (modified with an input signal 45 MHz (L5), 1227. 60 MHz (L2), 1381. 05 MHz (L3), and 1575. 42 MHz (L1) frequencies.
- The Galileo Navigation System uses the L-band similarly to GPS. Galileo is a Global navigation satellite system currently being built by the European Union (EU and European Space Agency (ESA
- The GLONASS System uses the L-band similarly to GPS.
Telecommunications use
GSM mobile phones operate at 800–900 and 1800–1900 MHz. GSM ( Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for Mobile phones in the Iridium (satellite) phones use frequencies between 1610 and 1625MHz to communicate with the satellites

Note: Canada uses slightly different central frequencies for L-band DAB while in many European countries DAB is limited part of Band III due to television and mobile two way radio using the rest.
Physics issues relating to band use
The band also contains the hyperfine transition of neutral hydrogen (the hydrogen line), which is of great astronomical interest as a means of imaging the normally invisible neutral atomic hydrogen in interstellar space. The hydrogen line, 21 centimeter line or HI line refers to the Spectral line created by changes in the energy state of neutral Hydrogen and Consequently parts of the L-band are protected radio astronomy allocations world-wide. Radio astronomy is a subfield of Astronomy that studies celestial objects at radio frequencies.
Optical communications L band
L band is also used in optical communications to refer to the wavelength range 1570 nm to 1610 nm. Optical communication is any form of Telecommunication that uses Light as the transmission medium
