Radio Frequency (RF) interference is caused by transmitters on the same or similar frequency to the one you're receiving — for example, baby monitors, cordless phones, amateur or personal radio transmitters, oscillating amplifiers (like audio or radiating aerial amplifiers).

Materials Used inRF Shielding Nickel Silver. Nickel silver is actually a copper alloy. ... Copper. Copper works well in RF shields because it naturally acts as an effective conductor, absorber and attenuator of RF signals. ... Steel. ... Aluminum. ... Elastomers Filled with Conductive Materials.

Limitations on the number of radio stations a single entity may own in an area are based on a sliding scale that varies by the size of the market: In a radio market with 45 or more stations, an entity may own up to eight radio stations, no more than five of which may be in the same service (AM or FM).

The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle.

In radio, and wireless communications in general, blocking is a condition in a receiver in which an off-frequency signal (generally further off-frequency than the immediately adjacent channel) causes the signal of interest to be suppressed.

Radio Frequency (RF) interference is caused by transmitters on the same or similar frequency to the one you're receiving — for example, baby monitors, cordless phones, amateur or personal radio transmitters, oscillating amplifiers (like audio or radiating aerial amplifiers).

Thin amounts of plastic wrap, wax paper, cotton and rubber are not likely to interfere with radio waves. However, aluminum foil, and other electrically conductive metals such as copper, can reflect and absorb the radio waves and consequently interferes with their transmission.

A number of materials can be used to block RF signals, including copper, aluminum, and steel. For example, cables are typically shielded with a thin aluminum foil or braided copper wires. Individual devices can be placed inside simple shielded boxes, but this is too inefficient for real device testing at scale.
