Application Note: Radio Frequency Interference In Hospitals

Hospitals are replete with sources of interference and many applications that require the ultimate in reliability to assure patient safety. Patient telemetry systems, cellular telephones, bluetooth devices, security radio systems, police and paramedic radios, Wi-Fi, microwave ovens, cordless telephone systems, light dimmers, fax machines, floor buffers, elevators, elevator controls, nearby cellular base stations, broadcast transmitters, and ultrasound systems all contribute to the harsh RF environment in hospitals. This may not be a lot worse than many businesses, but lives are at stake so it is critical to be able to quickly solve interference problems.
