97 Medical Apparatuses tested at the Academic Medical Center (AMC) Amsterdam for interference by WLAN/WiFi signals
report
This research describes the influence of WLAN 1 signals on medical apparatuses in the Academic Medical Center (AMC) Amsterdam. The results in this report were obtained by testing medical equipment with WLAN signals. A comparable research was reported earlier. See TNO report KvL/P&Z 2007.117 dated September 2007, Literature. At 20cm distance 3% of 97 tested medical apparatuses were disturbed. At 0cm distance (WLAN antenna against medical apparatus) 7% of the apparatuses were disturbed. The WLAN signals were transmitted at 100mW, which is the standardised power in the 2,4 and 5GHz frequency bands. The character of the disturbances was at 0cm distance unsafe at about half (4%) of the (7%) of the 97 tested medical apparatuses; the maximum distance at which interference was found was 30cm. The character of the disturbances varied between significant and unsafe, equally distributed over the distances.
