8.1
The antenna used on the Wireless LAN module is designed to be largely immune from the effects of
proximity detuning.
that great care is needed in their placement and orientation.
The Wireless LAN module can be used in most locations and orientations and is only marginally affected
by the presence of a significant ground plane in close proximity.
The antenna distribution is close to isotropic, which means that the orientation of mounting has only a
limited effect on the overall range. However the optimum range is achieved when the two antennae
are directly facing each other
8.1.1
The module should not be located in a sealed metal enclosure, as this will act as a Faraday cage and
severely attenuate the radio signal.
