Electromagnetic Field Generated by Wireless Alarm Devices

Together with the rise of importance of devices employing wireless networks based on the principle of radio frequency data transfers, also the discussion on harmfulness of the electromagnetic radiation has occurred. The authors of this paper obviously cannot provide unambiguous answers to stop this discussion. On the other way, they can provide the reader of this paper with real data obtained by measurements processed inside a semi anechoic chamber that were performed at several wireless alarm peripherals. The measured values are compared to the technical and hygienic standards so the reader can form an idea of the amount of the radiated energy. Moreover, examples of waterfall diagrams of spectra generated by the devices are also listed in this paper.
