Summary:
Studies have proposed that wireless local area networks (WLAN) can be applied in medical applications to enhance the quality of patient care, such as patient monitoring systems and hospital admission systems. However, there has been concern regarding the effect of electromagnetic interference (EMI) on medical equipment from wireless communication devices, especially those at close proximity to vital medical equipment. As a result, an investigation to examine the medical equipment due to interference from the WLAN devices was carried out. The outcomes have indicated that a WLAN system is safe for installation inside hospital premises, with only one of the fetal heart monitors found to be susceptible to the interference of an IEEE 802.11b WLAN system.
