What are radio frequency (RF) devices?
Radio frequency devices are office appliances that omit a radio frequency that uses or interferes with radio channel use. There are three categories of RF devices: intentional radiators, incidental radiators and unintentional radiators. The team over at National Association for Amateur Radio shares these definitions from FCC Title 47, Part 15:
Intentional radiator: § 15.3 (o) Intentional radiator. A device that intentionally generates and emits radio frequency energy by radiation or induction. This term generally means "radio transmitter." Examples are cordless telephones, baby monitors or garage-door openers.
Incidental radiator: § 15.3 (n) Incidental radiator. A device that generates radio frequency energy during the course of its operation although the device is not intentionally designed to generate or emit radio frequency energy. Examples of incidental radiators are dc motors, mechanical light switches, etc.
Unintentional radiator: § 15.3 (z) Unintentional radiator. A device that intentionally generates radio frequency energy for use within the device, or that sends radio frequency signals by conduction to associated equipment via connecting wiring, but which is not intended to emit RF energy by radiation or induction. Examples include computer systems and superheterodyne receivers.
The radio frequency spectrum chart there are many dedicated user groups. As you may know. there is concern that we are running out of radio frequency space to support our growing communications networks. Unintended contamination adds service disruption risk.
