Electromagnetic interference is the interference caused by an electromagnetic disturbance affecting the performance of a device, transmission channel, or system.
Moderate or high-powered wireless transmitters can produce EM fields strong enough to upset the operation of electronic equipment nearby. Cordless telephones, home entertainment systems, computers, and certain medical devices can fail to work properly in the presence of strong magnetic fields. Problems with EMI can be minimized by ensuring that all electronic equipment is operated with a good electrical ground system. Cords and cables connecting the peripherals in an electronic or computer system should be shielded to keep unwanted RF energy from entering or leaving.
