Dynamic attenuation will incorporate AP to AP readings as well as
site survey information and dynamically recalculate the path loss of
each radio to every grid cell on the floor plan, increasing coverage
and location accuracy.
This setting instructs the VisualRF engine to display all units of
measurements in Metric
This is the amount of memory dedicate to the VisualRF service. It is
not dynamically allocated and all the memory is consumed upon
starting the service. Be sure to check the memory and swap
utilization in the Systems
changes. The exact amount of memory used per floor plan will vary
heavily based on the size, number of devices and number of grid
cells on the floor plan.
• 25 floors or less 512 MB
• 50 to 75 floors 1 GB
• 75 to 100 floors 1.5 GB
• 100 to 200 floors 3GB
• 200 to 300 floors 5 GB (64-bit only)
• Above 300 8 GB (64-bit only)
Note: If you see "Out of Memory" errors in the SSL error log on the
System Status page you should increase memory allocation.
Number of threads that calculate path loss for each floor. These
threads also regenerate a floor's RF properties when new APs,
walls, or regions are added to a floor plan.
Number of threads that calculate the location of all clients
associated with access points on this floor plan.
Number of threads that service users accessing QuickView as well
as AMP to VisualRF communication.
Note: If users experience timeout errors while using QuicKView then
allocate additional UI Threads.
This timer indicates how often VisualRF will synchronize state (new
APs and Security) with AWMS.
