LAN module is powered down, the same restrictions on script operation as powersave 5
apply. The average current consumption in this mode is reduced to <4mA.
Powersave mode 1 requires beacons to be broadcast from an infrastructure access point. Therefore it
is not available when operating in ad-hoc (IBSS) mode.
9. Application Information
9.1 Antenna Location
The antenna used on the Wireless LAN module is designed to be largely immune from the effects of
proximity detuning. Normally, antennas operating at 2.4GHz are affected by their surroundings, so
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
