The most efficient way to achieve this is through 24/7 spectrum monitoring using automated wideband interference detection equipment. One such solution is to use an RF receiver that triggers an alarm if unrecognized signals are detected.

The only remedy is to shield the equipment. 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.

Radio wave frequency can be interfered with by a large number of items, including electric blankets, air conditioners, toaster ovens, and hairdryers. Additionally, devices used to communicate with other devices (cell phones, laptops, devices that utilize Bluetooth connections, etc.)

Spectrum Analysers are measuring devices that can display the level of an RF signal presented at their input (via a coupling transducer such as an antenna or probe). A spectrum analyser measures the different frequencies present in a signal. If there is any interference, it will show up as spikes or bands on the graph.

Spectrum analysis devices can be used to determine the frequency and received strength of RF interference. Spectrum analysis devices can also be used to identify frequencies that are free of interference should a responder use channel switching as a RF jamming mitigation tactic.

A tracking transmitter broadcasts a radio signal which can be detected by a directional antenna (typically a Radio Direction Finder). By rotating the antenna one can determine the direction the signal lies in and of course whatever it may be attached to. The EPIRB is an example of a similar device.

A simple method of determining the location of electrical interference is by using a portable battery-powered AM radio tuned to a quiet frequency at the lower end of the dial. You should hear static or a buzzing sound as you get close to the source of the interference.
