'Auto-clean' programs need a vector drawing to operate, they look for potential issues such as parallel lines that run for a defined distance, lines that are shorter than a defined distance etc. They then try to eliminate data that violates any of the defined rules. Once a drawing has been 'cleaned' in this way it is necessary for the user to assign RF properties to the remaining details in order to make use of the floor plan for future RF planning.

A virtual survey uses any form of drawing input that is available (see 'What files do I need to start off a virtual survey'). The drawings are used as the foundation for the virtual survey with a full RF model of the building being created as the input to the next stage of RF planning.

During the modelling phase we include a range of details to better emulate real world conditions that will be present when the wireless system is deployed. Details such as showing doors in the 'closed' position and room dividers put in place help to ensure that wireless cover is not degraded when the building is used for the purposes for which it was designed.

None of these features are available by simply 'auto-cleaning' an architectural design file.
Why do I need a virtual survey?

I've seen that some programs can automatically clean my floor plan drawings; how is a virtual survey any different to this?

What files do I need to start off a virtual survey?

I don't have any plans of my building, is there any way to get a virtual survey started?

What do I get with a virtual survey?

How much does it cost?
