Locking and Unlocking MAP Access Points

After you compute and place the necessary MAP access points for a coverage area, you can move them to fine-tune the wireless coverage. If you need a MAP to be located at a fixed location on the floor, you can lock its current location when you recompute the necessary coverage. A dual-radio MAP model that is part of two coverage areas and is not locked can be placed in the shared coverage area.

Assigning MAP If you do not plan to use the RF Auto-Tuning feature to automatically set Channels the channels on the MAPs after deployment and installation, use the

Assign Channels to MAPs option to assign channels to the MAPs.

Appropriate assignment of channels across the floor minimizes co-channel interference. The figure below shows how to minimize co-channel interference for an 802.11b environment when using the nonoverlapping channels 1, 6, and 11.
