Characteristics of wireless technology for healthcare applications: An overview

The application of wireless technology in healthcare is increasing, not only it enhances the quality of patient care and patient mobility, but also it leads to accurate clinical decisions making. However, the electromagnetic energy emitted by the wireless transmitter devices may affects the operation of the medical equipment, especially those in close proximity with one another. In this study, we investigated the wireless technology that has minimal electromagnetic interference on the medical appliances and identified the characteristics of that particular wireless technology. From this review study, the establishment of wireless techniques in healthcare environment depends on the wireless frequency band, the wireless transmitter output power, distances between the wireless devices and the medical equipment, and also the surrounding environment of the hospitals.
