RF Planning
To do RF Planning, you provide detailed information about your site and
buildings by importing AutoCAD DXF™, AutoCAD DWG, JPEG, or GIF
floor plan files of the buildings into 3WXM.
buildings by importing AutoCAD DXF™, AutoCAD DWG, JPEG, or GIF
floor plan files of the buildings into 3WXM.
As you import the floor plans, you can modify them to add or remove RF
obstacles. 3WXM includes a library of attenuators for building obstacles.
The library includes doors, walls, ceilings, and other physical obstructions
that you can select. Attenuators can be defined by height, width, type of
building material. 3WXM factors in the impact these objects have on how
the radio frequency (RF) signals flow through a given site.

If the network contains third-party APs, you can enter information for
these APs so that 3WXM takes the APs into account when calculating the
placement (and optionally, the channel and power settings) of the 3Com
MAPs.

By using this technique, you receive these substantial benefits:
Instead of you making a “best guess” as to how many MAPs you
require for the desired coverage and where MAPs should be placed,
3WXM automatically calculates how many MAPs you need and where
to place MAPs for optimal positioning.

Which Planning
Method Should I Use?
The more detailed your network plan, the better you will be able to
manage and monitor the network. However, there are other
requirements organizations should consider.

3Com suggests you use the RF Auto-Tuning technique if you are
installing MAPs without consideration to blanket coverage, throughput
concerns, or the number of users for whom service will be provided. RF
Auto-Tuning is ideal for small areas; for example, coverage that only
requires a few MAPs, or widely dispersed areas in a building, such as
conference rooms.
