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.

To jam a network, you need to broadcast radio signals on the same frequency, overpowering the original signal. Jamming devices that broadcast on a wide range of frequencies at once can disrupt everything from police radar to GPS systems, and are illegal in many countries.

5 Ways to Block Radio Waves in Your House Apply RF blocking paint on your walls. Use a Radio Frequency Blocking Wallpaper. Purchase an Aluminum Mosquito Net. Use RF Protection Mats and Canopies. Use RF Blocking Window Film.

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.

Radio frequency (RF) shielding is a form of electromagnetic shielding that blocks out radio frequencies. Certain test chambers are constructed with RF shielding, protecting devices under test (DUTs), usually related to electronics or computers, from radio frequency interference and enabling users to run accurate tests.

As a radio wave travels from the transmitting to the receiving antenna, it may be disturbed by reflections from buildings and other large obstacles. Disturbances arise when several such reflected parts of the wave reach the receiving antenna and interfere with the reception of the wave.

Proper grounding ensures that RF noise is conducted away to the ground instead of being emitted as radiation. Shielding, filtering, and grounding are the immediate answers to the question of how to stop radio frequency interference in electronic circuits.
