- Electromagnetic spectrum : The range of electromagnetic waves covering all frequencies and wavelengths.
- Telecommunications : Add brief definition or description
- Amplitude modulation : Changing the height of the peaks of a periodic waveform, such as a radio wave, to carry information.
- Antenna : Please do not use this term in your topic list, because there is no single article for it. Please substitute a more precise term. See Antenna (disambiguation) for a list of available, more precise, topics. Please add a new usage if needed.
- Frequency modulation : Technique for imposing information onto a electromagnetic signal of constant frequency -- the "carrier wave".
- Microwave : Add brief definition or description
- Modulation : The process of varying one waveform in relation to another waveform.
- Radio-Frequency Identification : Add brief definition or description
- Software-defined radio : Radio communication system where components that have typically been implemented in hardware are instead implemented using software on a personal computer or other embedded computing devices.
- Superheterodyne : A form of reception in which the frequency of an incoming signal is mixed with a locally generated signal and converted to an intermediate frequency in order to facilitate amplification and the rejection of unwanted signals.
- Joint Tactical Radio System : A wide-ranging replacement of conventional military radio and communications security equipment with software-defined radio
- SINCGARS : Add brief definition or description
- HAVE QUICK II : A family of military UHF jam-resistant radios, intended for air-to-air and air-to-ground use
- Joint Tactical Information Distribution System : The primary communications system used for sharing tactical information internally, and among NATO, Australia, and other U.S. allies
- ITU Frequency bands : Add brief definition or description
- IEEE Frequency bands : Add brief definition or description
- Cellular telephony : A set of techniques that let many low-powered portable telephones connect to the fixed network, often exchanging data and images as well as voice
- Cooperative Engagement Capability : A distributed computing and communications system principally aboard U.S. Navy warships, more than the AEGIS battle management system is often called. As opposed to the Joint Tactical Information Distribution System it does not share only the processed data from single sensors on single platforms, but shares a mutually computed model fusing all sensors
- Wireless local area network : A local area network, with a range in hundreds to thousands of meters, which transfers high-speed digital data without a direct physical connection between nodes on the network, usually by radio; the nodes are assumed to stay in one general area, as opposed to moving widely as in cellular telephony
- EU-NATO-US Frequency bands : Add brief definition or description
- Radar : (acronym for "radio detection and ranging") A technique used for detecting and tracking targets, navigation, imagery, and special applications.
- Classic rock : A radio format usually encompassing the mid-1960s to early 1980s years with an emphasis on guitar based bands such as Led Zeppelin or Bad Company. Since the 1980s, classic rock has also been used to loosely describe a genre of music redolent of the radio format.
- Led Zeppelin Radio : A commercial-free, satellite radio station on the XM Satellite Radio platform, broadcasting the music of Led Zeppelin.
- Triple M Classic Rock Digital : Australian Digital Radio station operated by Southern Cross Austereo from it's launch date on 25 November 2013, focused on the classic rock format.
- The Hands of Tyme : Two hour music programme on Sydney community radio station 2SER, which plays select songs of the psychedelic era from the mid-1960s to the mid-1970s.
