The RF Auto-Tuning feature can automatically set the power and channel
on each radio. RF Auto-Tuning settings are associated with the radio
profile that manages the radios. To change RF Auto-Tuning settings for a
radio profile associated with the coverage area, right-click on the
coverage area and select Properties. Navigate to the Area Associations
page. (See "Specifying Association Information" on page 144.)
3WXM determines the number of MAP access points that need to be
installed in the area and the number of WX switches needed in the wiring
closet (if the floor has them), and then places them on the floor plan. You
can move the MAP access points on the floor plan to more convenient
locations to simplify installation. 3WXM also determines the WX to which
a MAP should connect.
3WXM assigns transmit power levels and channels for each MAP. The
power levels and association rates are set to optimize cell sizes for the
coverage area. 3WXM shows the expected (simulated) coverage of the
completed design, and allows you to see how the coverage changes
when you make adjustments to MAP location or power levels.
Computing and When you perform Compute and Place for one or more coverage areas,
Placing MAP Access 3WXM automatically calculates the number of MAP access points you
Points for a Coverage require, based on coverage area information, and also places them in
Area appropriate locations on the floor.
3WXM assumes that MAPs are mounted on the ceiling and takes the
ceiling height into account when placing MAPs. 3WXM assumes that
coverage is required down to 3 feet above the floor (the average height
of a user's desk). By default, 3WXM assumes that you want to directly
connect the MAP access points to WX1200 switches and that you do not
want redundant MAP connections for backup. You can change these
design constraints.
By default, especially when you are performing Compute and Place for a
coverage area for the first time, the results do not account for existing
MAP access points. Manual overrides of the MAP results are not taken
into account if you perform Compute and Place again.
If you are modifying an existing coverage area with deployed MAP access
points or if you need to preserve manual changes made to the current
configuration, you can lock the MAPs. Locked MAPs cannot be moved or
deleted during the Compute and Place process.
