Computing MAP Placement 153
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
Placing MAP Access
Points for a Coverage
Area
When you perform Compute and Place for one or more coverage areas,
3WXM automatically calculates the number of MAP access points you
require, based on coverage area information, and also places them in
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.
You perform the following tasks to compute and place MAP access
points:
1 Specify design constraints. (See “To specify design constraints” on
page 154.)
2 Compute and place MAP access points. (See “To compute and place
MAP access points” on page 157.)
3 Review coverage area computation progress. (See “To review coverage
area computation” on page 158.)
