WiFi and Pacemakers
Earlier this year, one of the reports at the American Hearth Association meeting dealt with the effect of WiFi on pacemakers. Dr. Fritz Mellert of the University of Bonn:
. . . placed 25 pacemakers and 22 implantable cardioverter defibrillators made by all of the major device manufacturers at varying distances from wireless local area network (WLAN) transmitting antennas in order to study the potential for electromagnetic interference with device function. He subjected the cardiac devices to WLAN transmitting powers of both 100 mW, the upper limit in Europe, and 1,000 mW, the maximum output power permitted by the U.S. Federal Communications Commission.
He determined that there was no evidence of interference with all key programming and telemetry functions. There was one caveat — some non-critical functions showed interference when the pacemaker was within 10cm of a high output access point.
