Configuring Wi-Fi Zoning — Job Aid
Use this procedure as a job aid to configure the Wi-Fi association zone and roaming zone
thresholds for APs in your wireless deployment.
Procedure
1. Plan the number of APs that need to be deployed in the Wi-Fi deployment zone.
This depends on the capacity requirement of your deployment.
2. Evenly distribute the APs in the Wi-Fi Association coverage zone. Ensure that the
Association Zones of neighboring APs (of each AP) overlap by about 30 to 40%.
3. Configure the Wi-Fi association zone threshold on an AP. Use the following tables
as a guide to configure appropriate association zone and roaming zone thresholds
on the AP. The values are tabulated based on sample client distances from the
AP.
Table 1: Sample client RSSI values with respect to distance from the AP —
Operating frequency 5 GHz
The following sample values are based on an FCC domain AP (model AP 8120) operating
at 5.0 GHz and on channel 44. The values are sampled in a 90% empty office floor, for an
AP in a 10 feet high ceiling mount position.
