The Area Patch is strong enough to protect an area 200m around the patch.  It contains 4 layers of 64 antennas which absorb electromagnetic and radio frequencies and create a phase shift.  The echo created cancels out the negative effect of this type of radiaion on living cells.  It is ideal for protecting the whole home and all the people, animals and plants within it.  It offers protection against your neighbours Wifi signals and transmitting towers in your vicinity.  It will not effect the strength of signal for your Wifi or phone.
