General Guidelines
Following are general guidelines for all access points.

Always try to mount the AP as close to the users as possible for best performance. Be aware of
the environment. For example, if hospitals have metal doors, coverage can change when the
doors close. Old buildings can have metal grid work hidden under plaster or asbestos. Avoid
mounting the AP or antennas near metal objects, since that may affect the coverage area.

When using the 2.4 GHz frequency, the same one, six, and eleven channel scheme is used as in
the 5 GHz channel scheme. (See Figure 61.) Avoid putting all APs on the same channel, and
reuse channels if possible. See other Cisco deployment guides for more on this topic.
