From the results, the previously mentioned environments, e.g., event halls, airports, and shopping malls, have the following differences: 1) the number of people, 2) existence of mobile routers and tethering terminals, 3) use state of Wi-Fi, so that the positioning error becomes large as a sequel to the change of BSSlD(Basic Service Set Identifier) and RSSI(Received Signal Strength lndicator).","subitem_description_type":"Abstract"}]},"item_116_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"copyright©2014 IEICE","subitem_description_type":"Other"}]},"item_116_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_116_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_116_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_116_publisher_12":{"attribute_name":"出版者名(別言語)","attribute_value_mlt":[{"subitem_publisher":"The Institue of Electronics.
