VisiWave Blog

A maintenance release of VisiWave (v6.0.4 ) is now available for download. If you already own v6.0 of VisiWave, just download the eval version and install it over-top of your current version. Your existing license will continue to work. If you would like to evaluate VisiWave, just download the eval version and try it out.

New features in v6.0.4:

• Performance Issue with Changing "Group By" in AP List
  
  When a large number of APs are selected in the AP List and then
  "Group By" is changed, it can take a long time to switch how
  the APs are grouped. This has been fixed.
  
  
• Out-of-Memory Error in Large Surveys When Selecting Many Data
  Points
  
  For very large surveys, loading all the discovered access
  point readings in the Wi-Fi Details view below the map in the
  Survey View could cause out-of-memory errors. VisiWave now
  limits the number of rows that are added to this list.
  
  
• Generating PDF Reports with Non-ASCII Characters in Filenames
  
  When generating a PDF report, if the filename you enter contains
  non-ASCII characters, images in the report weren't being shown.
  This is no longer a restriction.
  

New features in v6.0.3:

• Door & Window Issue With Predictive Surveys
  
  In some rare cases, the order that doors or windows are
  included was causing VisiWave to hang. The ordering is
  now changed automatically.
  
  
• View in Chanalyzer Issue with Large Datasets
  
  VisiWave had an issue when using the View in Chanalyzer
  feature when the range included too many data points.
  Chanalyzer would load but no data would be included. This
  situation is now fixed.
  
  
• Google Earth Report Default Extension
  
  If a file extension wasn't provided for the report file,
  the file was given the extension of KML. But it needed to be
  KMZ for the Google Earth files VisiWave creates. An extension
  of KML would cause the embedded images to display as large
  X's.
  
  
• Google Earth AP Coverage Maps Issue
  
  If you generated an AP Coverage map for Google Earth and had
  both "What to Map" set to "Strongest" and "Highlight Overlaps"
  set to anything other than "None", then VisiWave couldn't
  generate the Google Earth report. Note that there are never
  highlighted overlaps when mapping the strongest APs so usually
  this wasn't an issue.
  

New features in v6.0.2:

• Set GPS Location Issue
  
  If "Get Location from GPS Device" was selected from the "Set
  GPS Location" menu item before any data was collected, then
  the program would crash.
  
  
• Channels Under Noise Can't Be Selected When First Adding
  Spectrum Data
  
  In Survey View in the right pane, the 2.4GHz and 5GHz channels
  under "Noise" can't be selected when you collect the first set
  of spectrum data points. The channels remained grayed out.
  You had to save the survey file and re-load it before you
  could access the noise channels.
  
  
• Predictive Heatmap Issue with Large Survey Areas
  
  A large survey area (50m on a side or more) could have had
  issues producing accurate predictions when the radio was placed
  near the top of barriers. The simulation had a path over the
  barriers which was making the signal strengths too generous.
  
  
• Channel Maps Weren't Handling Some In-Between Channel Numbers
  
  Some channels that were "wide" (40MHz, 80MHz, or 160MHz) couldn't
  be selected in a Channel map. Now VisiWave handles all common
  channel numbers regardless of channel width.
  
  
• Rotate Horizontal Wasn't Working for Dipole Antennas
  
  For predictive surveys with radios set to have dipole antennas,
  the Rotate Horizontal setting wasn't affecting the heatmap
  pattern. It is now functioning correctly.
  
  
• Predictive Heatmaps Had White or Gray Regions
  
  With a few combinations of Min and Max color legend settings,
  some regions of the colored heatmap would show up as white or
  gray when they should be a dark red (when using the default
  color scheme).
  
  

New features in v6.0.1:

• Added Support for Channel Bonding in Predictive Surveys
  
  When doing a simulation, you can now set a radio's channel
  width in addition to just its frequency in the 5GHz band.
  You do this by right-clicking on a radio and selecting Edit
  Radio. This allows you to simulate the effects of channel
  bonding. For example, you can select channel 36 and say that
  it is a 40MHz channel to bond channels 36 and 40 together.
  
  
• Issue Fixed with Exporting Simulation Data to CSV
  
  VisiWave was exporting only half the simulated signal values
  to the CSV file. Every other value in the X direction was
  skipped. Now all the values are exported.
  
  
• Performance Improvements When Selecting Radios in Predictive Mode
  
  There were a few cases where updating the heatmap in Predictive
  mode took much longer than needed.
  
  
• Allow Merging of Survey Files When Floor Plan Sizes are
  Slightly Different
  
  Due to some rounding issues, some survey files couldn't be
  merged even though they used the same floor plan image and
  scale.
  
  
• Half Power Beamwidth Antenna Types Are More Effective
  
  For Predictive Surveys, the effect of the horizontal and
  vertical rotations for half power beamwidth antennas wasn't
  strong enough. And the rotations didn't match the
  documentation. These issues have been fixed.
