Signals intelligence (SIGINT) is the act and field of intelligence-gathering by interception of signals, whether communications between people or from electronic signals not directly used in communication. Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis. Traffic analysis—the study of who is signaling to whom and in what quantity—is also used to integrate information, and it may complement cryptanalysis.
Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure radio communications.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods.
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information.
An identity document is any document that may be used to prove a person's identity. If issued in a small, standard credit card size form, it is usually called an identity card, or passport card. Some countries issue formal identity documents, as national identification cards that may be compulsory or non-compulsory, while others may require identity verification using regional identification or informal documents. When the identity document incorporates a person's photograph, it may be called photo ID.
The radiotelephony message PAN-PAN is the international standard urgency signal that someone aboard a boat, ship, aircraft, or other vehicle uses to declare that they need help and that the situation is urgent, but for the time being, does not pose an immediate danger to anyone's life or to the vessel itself. This is referred to as a state of "urgency". This is distinct from a mayday call, which means that there is imminent danger to life or to the continued viability of the vessel itself. Radioing "pan-pan" informs potential rescuers that an urgent problem exists, whereas "mayday" calls on them to drop all other activities and immediately begin a rescue.
Radiotelephony procedure includes various techniques used to clarify, simplify and standardize spoken communications over two-way radios, in use by the armed forces, in civil aviation, police and fire dispatching systems, citizens' band radio (CB), and amateur radio.
Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data. Both human-made and natural sources generate changing electrical currents and voltages that can cause EMI: ignition systems, cellular network of mobile phones, lightning, solar flares, and auroras. EMI frequently affects AM radios. It can also affect mobile phones, FM radios, and televisions, as well as observations for radio astronomy and atmospheric science.
France 24 is a French publicly-funded international news television network based in Paris. Its channels, broadcast in French, English, Arabic and Spanish, are aimed at the overseas market.
ISO 11784 and ISO 11785 are international standards that regulate the radio-frequency identification (RFID) of animals, which is usually accomplished by implanting, introducing or attaching a transponder containing a microchip to an animal.
Radio France Internationale, usually referred to as RFI, is the state-owned international radio news network of France. With 59.5 million listeners in 2022, it is one of the most-listened-to international radio stations in the world, along with Deutsche Welle, the BBC World Service, the Voice of America, and China Radio International.
The mass media in Burkina Faso consists of print media and state-supported radio, news, and television stations, along with several private broadcasters with programs consisting of sports, music, cultural, or religious themes.
The clipped tag is a radio frequency identification (RFID) tag designed to enhance consumer privacy. RFID is an identification technology in which information stored in semiconductor chips contained in RFID tags is communicated by means of radio waves to RFID readers. The most simple passive RFID tags do not have batteries or transmitters. They get their energy from the field of the reader. They transfer their information to the reader by modulating the signal that is reflected back to the reader by the tag. Because tags depend on the reader for power their range is limited, typically up to 10 meters (33 ft) for UHF RFID tags.
Recognition may refer to:
Procedure words are words or phrases limited to radio telephone procedure used to facilitate communication by conveying information in a condensed standard verbal format. Prowords are voice versions of the much older procedural signs for Morse code which were first developed in the 1860s for Morse telegraphy, and their meaning is identical.
The Rowing Federation of India (RFI) is the central body for the game of rowing in India. It was formed on 30 August 1976 with a view to make the sport of Rowing popular in India. It is affiliated with the Indian Olympic Association and Fédération Internationale des Sociétés d'Aviron and Asian Rowing Federation.
The procurement of Landing Platform Docks (LPD) by the Indian Navy, formerly known as the "Multi-Role Support Vessel Program" (MRSV) - is an initiative of the Indian Navy (IN) to procure a series of landing platform docks, specific vessels dedicated to amphibious warfare, as part of the service's strategy to augment its capabilities of amphibious warfare, disaster-response, humanitarian assistance and auxiliary duties.
An invitation to tender is a formal, structured procedure for generating competing offers from different potential suppliers or contractors looking to obtain an award of business activity in works, supply, or service contracts, often from companies who have been previously assessed for suitability by means of a supplier questionnaire (SQ) or pre-qualification questionnaire (PQQ).
