The Cisco WCS administrator wants to create an accurate RF heat map based on RF prediction data.
Which statement about map creation in Cisco WCS is true?
A . The administrator must manually add walls, doors, and windows to the map.
B . Cisco WCS automatically detects walls, doors, and windows and adds them to the map, but only when Cisco WCS Navigator is available.
C . Cisco WCS automatically detects walls, doors, and windows and adds them to the map, but only when a Cisco 3300 Series MSE is available.
D . All walls, doors, and windows must be included in the file that is uploaded as a background map.
Answer: A
Explanation:
General Notes and Guidelines for Using the Map Editor Consider the following when modifying a building or floor map using the map editor.
Cisco recommends that you use the map editor to draw walls and other obstacles rather than importing an .FPE file from the legacy floor plan editor.
If necessary, you can still import .FPE files. To do so, navigate to the desired floor area, choose box, and browse to and choose the .FPE file.
You can add any number of walls to a floor plan with the map editor; however, the processing power and memory of a client workstation may limit the refresh and rendering aspects of WCS. Cisco recommends a practical limit of 400 walls per floor for machines with 1-GB RAM or less. All walls are used by WCS when generating RF coverage heatmaps.
However, the MSEs use no more than 50 heavy walls in its calculations, and the MSE does not use light walls in its calculations because those attenuations are already accounted for during the calibration process.
If you have a high resolution image (near 12 megapixels), you may need to scale down the image resolution with an image editing software prior to using map editor.
