Abstract (en)
[origin: WO9918688A1] The present invention provides an apparatus for protecting an electronic apparatus against the transmission of radio waves from a nearby mobile communication apparatus. The apparatus comprises a plurality of radio wave generators for generating inhibiting waves transmitted to the mobile communication apparatus in order to block transmissions from the same. The invention further includes means for sweeping the frequency of the plurality of radio wave generators in different frequency ranges adjusted to cover all frequency ranges of the communication apparatuses.
