General Considerations Regarding Access Points
Following are some guidelines to remember regarding all access points.
1. Always try to mount the AP as close to the users as possible for best performance. Be aware of the
environment; for example, hospitals have metal doors, coverage can change when the doors close,
old buildings can have metal grid work in the plaster or asbestos. Avoid mounting the AP or antennas
near metal objects, as doing so can change the coverage area.
2. When using the 2.4 GHz frequency, the same 1, 6 & 11 channel scheme is used as is the 5 GHz
channel scheme (Figure 60). Avoid putting all of the APs on the same channel, and reuse channels
as you can. See our other deployment guides for more on this topic.

3.
Try to determine which clients are going to be used and check the coverage using those clients. For
example, a PDA or Wi-Fi phone might not have the same range as a notebook or tablet.
Tip Verify coverage using the worst performing clients that you intend to deploy.
