Kindly, I am looking to provide me the tool to insert the AutoCAD
drawings in order to get the best coverage for Wi-Fi access points as
well as the recommended number of access points in each floor and
building.

I don't know of any tool that will automatically design your indoor
wireless network for you based on an Autocad drawing. There are just
too many uncontrolled variables, such as interference, furniture, and
construction material for such a tool to work effectively indoors.
However, for outdoors, there are some MatLab wi-fi simulations that
might be usable.

For a good overview on wireless layout and deployment, see the
archived "Intel Wireless HotSpot Deployment Guide" at:

Hi Jeff,

have you already tested Ekahau ?
It doesn't seem to work properly under indoor , office environment
as topology generated by tracking software is subject to interference
error,
so a autocad like drawing seems to be a description of conception and
not a real environment generated map
http://i.cmpnet.com/nc/design06/0831/graphics/0831rollout3a.gif.

And for outdoor use there is need to use Matlab tools as a simple
triangulation algorithm works perfectly.
I am really surprised Ekahau doesn't go into details of indoor
tracking showing marketing materials only.
Of course there is reverse algorithm for discovering x,y,x position of
each wifi sender/tag for a specific location and a number of wifi
senders, but what you get is not necessary circular range/ signal
level pictures as on the
above picture.
What is presented on the above picture is signal level aproximation
for wifi network switching packets under best reception/signal level
algorithms and has nothing to do with a real environment
circumstances.
