    摘要： A method and apparatus for estimating a position of an access point (AP) in a Wi-Fi system is provided. The method includes measuring a strength of a signal, transmitted by the AP, at three or more measurement points (MPs), selecting an imaginary attenuation factor, calculating a range between the AP and each of the MPs on the basis of the imaginary attenuation factor and a strength of a signal measured at the MP, calculating an intersecting point of ranging circles in each of which a position of the MP is a center and the range between the MP and the AP is a radius, calculating a best intersecting point from among a plurality of the intersecting points obtained by repeating the calculating the range and the calculating the intersecting point of ranging circles while changing the imaginary attenuation factor, and estimating the best intersecting point as the position of the AP.

    摘要： An apparatus for providing vehicle accident information periodically collects vehicle travel information, and stores vehicle travel information that is collected during an accident of a vehicle, in a vehicle black box. The apparatus for providing vehicle accident information collects information about other vehicles through communication with the other vehicles during the accident of the vehicle, and stores the collected information in the vehicle black box. Since the information about the other vehicles is collected through communication with the other vehicles as described above, it is possible to provide more accurate and efficient information required for dealing with the accident. In addition, vehicle accident information, which includes time when an accident occurs, location where an accident occurs, and the type of accident, is transmitted to a related agency such as a police station and a traffic center, so that it is possible to quickly deal with the accident.
