This article provides information on the requirements needed to create wireless heat maps. 


All NPM versions


Note: Before creating a wireless heat map, make sure to obtain an image of the wireless coverage area, such as a floor plan. Get the measurement of the distance between two points on the image and choose the physical location of the access points to accurately place them on the map.

The floor plan must be a graphic file in one of the following graphics formats:

  • Graphics Interchange Format (.gif, non-animated)
  • Tagged Image File Format (.tiff)
  • Joint Photographic Experts Group (.jpg)
  • Microsoft Windows Bitmap (.bmp)
  • Portable Network Graphics (.png


Requirements in adding Access Points (AP) on maps:

  • The wireless LAN controllers are already configured in the Orion Platform product.
  • Cisco supports only two controllers.
  • The wireless heat map poller should be enabled on the wireless LAN controllers that are used in the map.

To improve the accuracy of wireless heat maps, take samples of the signal strength on real devices.
Wireless heat maps display the ideal wireless signal coverage. However, they do not count physical obstacles, such as office walls and other blockages. Measure the signal strength on mobile devices, laptops, or other handheld devices connected to your wireless networks. The values are stored as signal samples to represent the signal strength in specified locations or used to calculate the signal coverage on wireless heat maps.
