Abstract

Embedded systems widely used for wireless communication such as W-LAN, Bluetooth and ZigBee operate on ISM (Industrial, Scientific and Medical) band but they can be seriously affected by electromagnetic interference radiated from ISM apparatus. Therefore C.I.S.P.R. reports proposed limits for the protection of telecommunication from interference from ISM equipment. In this paper, we clarify the methods for calculating limits for disturbance signal for Embedded Systems in ISM band and propose simple way of calculating limits for interference signal in both above and below 1 GHz band cases.
