Channel Visualization - Extreme Networks Summit WMScanner User Manual

Configure Grid Bin Size - The Grid Bin Size sets the resolution of the visualization grid. Increasing this
●
number produces more points in the building over which data is calculated and displayed. This will
increase the amount of time required to draw the heat map. For typical indoor office environments,
a value of one meter generally works well. This value should always be set to something less than
the Distance Visualization Limit. Decreasing the Grid Bin Size produces more grid bins over the
Boundary Region. Increasing the Grid Bin Size produces fewer grid bin points in the Boundary
Region.
To exit the Visualization Options dialog box and save your changes, click OK. To exit without saving,

Channel Visualization

The Channel visualization mode allows you to view regions of coverage colored by the best serving
channel (20 or 40 MHz width) to that region. If you have selected all MAC addresses in the
Visualization panel filters, the Channel visualization shows the best serving channel for MACs detected
during the currently loaded measurement runs. This view helps you to verify your facility's channel
plan layout. To open coverage visualization, choose the Channel option.
You can use the Visualization panel filter to view the coverage area for a specific channel (20 or 40 MHz
width) or for a specific MAC address. You can select both 20 and 40 MHz channels. This can be useful
if you want to view the areas of your facility where a client can obtain service from a particular channel
or AP.
You can also fine tune the signal strength cutoff criteria to display channel coverage regions by
adjusting the Signal Power filter on the Visualization Panel.
