Calculation Settings:

Spillage Factor: Specifies the size of the area as a multiplier of the actual layout area over which Planner will assess the WLAN signal spillage. For example, if you set the spillage factor to 2, the system will assess the signal strength over 2 times along each dimension of the layout. The system maintains the center of the layout so that you can observe the spillage symmetrically in all directions.

RSSI Calibration: Planner calculates the Received Signal Strength Indicator (RSSI) at each cell in the layout based on ideal conditions. It applies this RSSI calibration factor to account for un‐modeled objects like furniture, humans and so on, antenna/feeder losses, RF properties of Client cards, and layout inaccuracies. Planner applies the Calibration factor symmetrically to all the cells. The range for RSSI Calibration is ‐40 dB to 40 dB. The default for RSSI calibration factor is ‐10 dB.

Path Loss Model Settings:

Application Environment: Select the application environment from the drop‐down list.

Min Attenuation Factor: Displays the minimum attenuation factors for 802.11a/n and 802.11b/g/n depending on the application environment selected.

Max Attenuation Factor: Displays the maximum attenuation factors for 802.11a/n and 802.11b/g/n depending on the application environment selected.

ALPHA and BETA: Displays the advanced calculation parameters.

Location Properties: Local Material Repository Tab

The Local Material Repository tab gives a list of available materials in the Local Repository of that .spm file. Refer to the Local Material Repository section to see the various functions you can perform from this tab.
