Taken together, all forms of electromagnetic energy are referred to as the electromagnetic "spectrum. They are collectively referred to as "radiofrequency" or "RF" energy or radiation. The RF waves emanating from an antenna are generated by the movement of electrical charges in the antenna.
The FCC's New RF-Exposure Regulations
Radio Frequency Safety | Federal Communications Commission
Jump to navigation. Many consumer and industrial products make use of some form of electromagnetic energy. Because of its regulatory responsibilities in this area the Federal Communications Commission FCC often receives inquiries concerning the potential safety hazards of human exposure to radio-frequency RF energy. The information on this page provides answers and information to inquiries regarding RF Safety. The FCC is required by the National Environmental Policy Act of , among other things, to evaluate the effect of emissions from FCC-regulated transmitters on the quality of the human environment. Specifically, the FCC: 1 streamlines its criteria for determining when a licensee is exempt from our RF exposure evaluation criteria; 2 provides more flexibility for licensees to establish compliance with our RF exposure limits; 3 specifies methods that RF equipment operators can use to mitigate the risk of excess exposure, both to members of the public and trained workers such as training, supervision, and signage ; and 4 upholds its prior decision to consider the exposure limit for the outer ears to be the same as for other body extremities. In the Notice of Proposed Rulemaking the FCC proposes to formalize additional limits for localized RF exposure and the associated methodology for compliance for portable devices and wireless power transfer WPT equipment on top of its already existing limits that apply in the frequency ranges over which these devices will operate kHz to GHz , and considers extending the applicable frequency range to frequencies outside of this range as well 3 kHz to 3 THz.
Radio Frequency Safety
Amateur radio frequency allocation is done by national telecommunication authorities. Globally, the International Telecommunication Union ITU oversees how much radio spectrum is set aside for amateur radio transmissions. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license. Radio amateurs use a variety of transmission modes, including Morse code , radioteletype , data, and voice.
U-NII 2 is further divided into three subsections. Wireless ISPs generally use 5. In the USA licensed amateur radio operators are authorized 5.
