When vast quantities of cell phone, radio, and other signals pollute the air, the variety of frequencies begin to combat with one another, which can cause important electronics to fail. The solution to this is EMI shielding. For anyone unfamiliar with the concept, an EMI (electromagnetic interference) shield is a physical coat of conductive or magnetic metal that blocks the
negative effects of electromagnetism on various types of electronic devices and communication systems. Below, we list a few of the industries that benefit from EMI shielding.
1. The Military
Most pieces of military equipment, including aircraft, tanks, and radios, utilize EMI shielding to prevent enemy equipment from interfering with or disrupting communication signals. Garbled radio signals can prevent the ability to share essential information, and disabled GPS in military vehicles can put servicemen in harm’s way. EMI shielding enables such equipment to perform properly, without the potential for complications.
2. The Medical Field
In today’s environment, there are bound to be a multitude of cellphones, tablets, and other such devices inside any hospital at any given time. Errant electromagnetic signals, however, can confuse the information that medical devices are trying to transmit and put patients’ lives at risk. EMI shielding adds a lightweight protection that guards medical machines against other frequencies, preventing critical mistakes. This allows staff, patients, and visitors to use cellphones and tablets without affecting any important machines.
3. Agriculture
This may not be an industry you’d expect to utilize EMI shielding, but like any other profession, farmers don’t have the time to deal with compromised equipment. Data collection, GPS, and drones are all becoming regular fixtures in the farming and agricultural industries—and like everything else, these devices are susceptible to the dangers of interfering radio frequencies. The agricultural industry, therefore, is another industry that benefits from the protection of EMI shielding.
