Figure 76. Capacity Planning – Advance Parameters

Specify the factors you would like to consider for WLAN capacity planning. These are ‘What‐If’ scenarios.

•Select the effects on AP capacity:

¾802.11 medium access anomaly: Select to consider the proportion of active users at various data rates.

¾802.11 medium access contention: Select to consider bandwidth contention determined by the total number of active users per AP and the amount of uplink traffic.

¾802.11 bandwidth efficiency: Select to consider the impact of overhead on bandwidth efficiency.

•Select either of the type of per AP capacity estimate (based on the selected factors) to plan the WLAN:

¾Conservative: Uses the worst case per AP capacity to estimate the number of APs required. This option usually estimates more number of APs.

¾Optimistic: Might overestimate per AP capacity than observed in practice. This usually requires less number of APs compared to the Conservative estimate.

¾Average: Moderately estimates per AP capacity and is a balance between the Conservative and Optimistic options. This is the default selected.

•Accounting for the effect of Wi‐Fi interference gives a more accurate estimate of capacity. For instance, in a scenario with densely packed APs, the inter‐AP interference may considerably degrade the capacity. In some cases, the capacity requirement may not be feasible due to high interference. Specify if you want to consider the effect of Wi‐Fi Interference.
