Interference with the meaning of electromagnetic interference, also radio-frequency interference (EMI or RFI) is – according to Article 1.166 of the International Telecommunication Union ' s (ITU) Radio Regulations (RR) [8] – defined as "The effect of unwanted energy due to one or a combination of emissions, radiations, or inductions upon ...
A line filter (aka EMC filter, EMI filter, RFI filter) is an electronic filter that is placed between the mains electricity input and internal circuitry of electronic equipment to attenuate conducted radio frequencies radio frequency interference (RFI), also known as electromagnetic interference (EMI).

For example, an RFID tag attached to an automobile during production can be used to track its progress through the assembly line, [citation needed] RFID-tagged pharmaceuticals can be tracked through warehouses, [citation needed] and implanting RFID microchips in livestock and pets enables positive identification of animals.

It may be said that radio interference and its correction arose with the first spark-gap experiment of Marconi in the late 1800s. [3] As radio communications developed in the first half of the 20th century, interference between broadcast radio signals began to occur and an international regulatory framework was set up to ensure interference-free communications.
A request for information (RFI) is a common business process whose purpose is to collect written information about the capabilities of various suppliers. [1] Normally it follows a format that can be used for comparative purposes. An RFI is primarily used to gather information to help make a decision on what steps to take next.
Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
This is a partial list of RFCs (request for comments memoranda). A Request for Comments (RFC) is a publication in a series from the principal technical development and standards-setting bodies for the Internet, most prominently the Internet Engineering Task Force (IETF).
