 Coverage...
The map to the right is
the best representation of the final 13cm coverage area to
date. To view the map in close up click on the map shown. However the map
prediction does not show all the "RF problems"
caused by many Wireless Area Networks (WANs), microwave
ovens and other forms of interference that cannot be accounted for by the prediction
software. 3cm coverage should be fairly similar. We will
post a more accurate map as more testing is carried out and
more reports are received.
