Abstract
A wireless communication network system includes: a location estimation device includes: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: collecting information, for each wireless device in a pair of wireless devices communicating with each other in the wireless communication network, as to the number of occurrences of duplicate reception caused by the data retransmission performed when the reception acknowledgement does not reach the transmitting wireless device; and estimating the location of an interference source of radio wave in a wireless communication network based on the collected information as to the number of occurrences of duplicate reception such that the location of the interference source is closer to one of wireless devices in the pair with a less number of occurrences of duplicate reception than to the other one of the wireless devices in the pair.
