I recently attended the Ekahau Certified Survey Engineer (ECSE) training course, presented by Keith Parsons. In addition to learning about using Ekahau Site Survey (ESS), Keith also shared some valuable insights in to best practice wireless LAN design and surveying techniques. One of these insights was a best practice approach to measuring loss through obstructions and attenuation areas, such as doors, walls and warehouse racking, when gathering data for a WLAN predictive model. In this article, I’ll share the details of that approach and some mistakes you might be making in your own measuring approach. Please visit the Ekahau blog site to see my guest posting for the full details on this topic.
