摘要： In a position detection system utilizing a WLAN supporting multiple data transfer rates, it is possible to reduce the number of required installed base stations, so system construction costs can be lowered. In a wireless station, a transmitted signal is judged at the time of transmission, and in case it is normal user data, the signal is transmitted by setting optimal transmission parameters for which a high communication throughput with wireless communication is obtained, and in case it is a position detection signal, the aforementioned signal is transmitted by setting transmission parameters for which the service range is increased. As a transmission parameter for which the service range is increased, a low data transfer rate or a long preamble length is used.

摘要： In any indoor location, whenever operating a wireless terminal position detecting system comprising a transferable wireless terminal, a plurality of base stations individually allowing a connection from said wireless terminal, and a plurality of wireless receiving stations individually receiving wireless signal from said terminal and base stations, there is a problem in terms of the provision of a method for minimizing positional detection error on the part of said wireless terminal and a method for practically realizing said method. Hence, to solve the above problem, the present invention provides a wireless terminal position detecting method featuring the function to evaluate the result of measurement against wireless signals from an objective wireless terminal received by individual wireless receiving stations based on a definition of a plurality of position detectable areas designating a geographic range required for detecting actual position of said objective wireless terminal and also based on another definition for specifying plural wireless receiving stations each being located at a predetermined known position allocated for individual areas for detecting actual position of the objective wireless terminal in respective position detectable areas before eventually determining the actual position of the objective wireless terminal.

摘要： When one base station to which a terminal is to connect is determined from a plurality of base stations in a wireless communication system, the best base station is selected according to the communication quality or the content of communication services. In the wireless communication system, the plurality of base stations are classified into a plurality of groups. Indexes of communication quality between the base stations and the terminal are obtained and, for each group, the characterizing quantities of the indexes of communication quality are calculated. The base station group with which the terminal is to communicate is specified based on the characterizing quantities. One of the base stations in the specified group is determined as a communication destination base station.
