140 Using RF PlanningNN47250-101 (320665-G Version 02.01)5 When you are satisfied with the results, click Finish.Model RF ObstaclesWhen planning a Nortel network, consider how the building layout and physical objects affect signal loss. Walls,windows, and doors absorb RF signals, and different building materials have different attenuation factors.You can model an RF obstacle on your floor plan and assign the obstacle type and attenuation factor, or assign anobstacle type and attenuation factor to objects in a DWG or DXF drawing. WMS uses these values when calculatingcoverage for the network.If you do not have an imported drawing or if you are working with a GIF or JPEG image, create RF obstacles manually.If you are using an imported CAD drawing, convert many of the objects in the drawing into RF obstacles. All objectssimilar in construction material should be placed in one layer. For example, if the drawing file has walls in different
