Example Basic Guidelines Process
Basic Guidelines with Optional Site Survey
The Basic Guideline approach is based on empirical data from existing wireless deployments and is
adequate for most deployments. This approach is based on most enterprise buildings having common RF
characteristics, and that only a part of the building needs to be characterized to verify the access point
coverage for the entire building. This approach leverages the algorithms built into the Cisco WLAN
Solution Radio Resource Management (RRM) that ensure that the overlap between access points is
minimized and that coverage holes are detected and eliminated before clients find them.
When deploying 802.11 wireless LANs to support Voice over IP (VoIP) telephones, such as SpectraLink
NetLink Telephones, a few special considerations are needed in the deployment process. When
deploying an 802.11 voice system, full coverage with an average user throughput of 5 Mbps or more
should be used. Areas such as stairways, bathrooms, cafeterias and outside areas may require special
consideration and access points. These are areas that are not typically critical for data users but are
critical coverage areas for voice users who want seamless coverage.

Determining the Radius and Z Factor
This section helps you to determine the coverage area of a Cisco Radio based on the building type and
desired average user performance using the table below. The Z factor represents the length of a square
that corresponds to the coverage area of the access point.
