Impact of Wi-Fi network coverage planning on the logistics objects’ location accuracy

The use of Wi-Fi networks to construct a system for determining the object’s location inside warehouses is simplest and most cost-effective way solving logistical problems. positioning in such based on measuring received signal strength level with application lateration (trilateration) method calculate target’s coordinates. This requires taking into account electromagnetic environment room fulfillment certain requirements construction network serving as tool. Incorrect access points placement premises leads significant error, unacceptable cases system’s application. article isdevoted improvement accuracy by structure correction accordance coverage frequency planning. To implement algorithm determination distances between mobile object an point, three radio wave propagation models were used, selected from variety similar after preliminary analytical experimental studies. power loss coefficients used signal’s passing through partitions floors adapted configuration features rooms which experiments conducted.
