Design Model
Threeradio butt ons, definedin Table 372 , allowyou to control the kindo fmodel used to determine the number and
type of APs.

Radio

Button Description

Coverage Usethis option to let RF Plan automatically determine the number of APs based on desired data
ratesand the configuration of your building.
Thehi gher thedata rate, the smaller the coverage area, and the more APs that are required.
Coveragei sthe most common type of installation.
Capacity Usethis option to let RF Plan determine the number of APs based on the totalnum ber ofusers,
ratioof users to APs, and desired data rates.
Capacity-basedcoverage is useful for high capacity conference or training rooms, where the
APscould have a high volum e ofusers.
Custom Usethis option to specify a fixed number of APs.
Customcoverage is useful for deployments with a known number of APs or if you have a fixed
projectbudget.

Overlap Factor
The OverlapFactor is the amount of signal area overlap when the APs are operating. Overlapis important if an AP
fails as it allows the network to self-healwith adjacent AP s powering upto assume some of the loadfrom the failed
device. Althought heremay be no holesin c overagei n this scenario, there is likely to be a loss of throughput.
Increasing the overlapallows for higher throughputs when an AP has failed and allows for future capacity as the
numberof users increases.
You can select a pre-determinedvalue from the drop-downoverlap menu or specify a value in the text box to the left
of the drop-down.The following table describes the available options.
