摘要

PROBLEM TO BE SOLVED: To provide a wireless network quality presenting device capable of easily comprehending the quality state of a wireless network at a glance.

SOLUTION: The wireless network quality presentation system includes: a KPI arithmetic unit 70 which statistically processes network quality information gathered from a plurality of mobile terminals to calculate KPI values by a plurality of unit areas laid out on a map; a totaling device 80 which receives communication sequence information and transmission position information recorded at a mobile terminal in case of a communication error; and a display device 90 which displays an area boundary line in different forms on the map according to the KPI values and communication error occurrence states of the unit areas. The display device 90 also has a function of displaying communication sequence information gathered by the respective mobile terminals and communication sequence information gathered on the side of a base station (maintenance terminal) in case of communication error occurrence.
