摘要： Provided are an access point arrangement device and a method for wireless location determination. An access point is arranged on a numerical map, received signal strength of a signal received from the access point for each grid point is calculated, and DOP and position error per grid point are calculated by using the received signal strength per grid point. It is determined whether to rearrange the currently arranged access point based on a ratio of a grid point with DOP less than a threshold value for entire grid points on the numerical map and a ratio of a grid point with a position error that is less than a threshold value.

摘要： The present invention relates to a location measuring method using an access point, and an apparatus using the same. According to the present invention, a location of a terminal is estimated by using a signal strength received from an access point installed at a known position in a wireless network, and location of the access point installed at an unknown position is estimated by using a signal strength received from the access point installed in the unknown position and estimated location information of the terminal. In addition, a location of the terminal is finally calculated by using estimated location information of the access point installed at the known position. As described, the location of the terminal is determined by using estimated location information of an AP that is randomly installed by a user (that is, installed at an unknown position), and therefore a location of an AP installed in an area where it is difficult to measure and availability of location measurement can be improved. In addition, a signal strength measurement value, estimation location information of an AP installed at a known position, and estimation location information of an AP installed at an unknown position are used for location information calculation of a terminal, and accordingly, accuracy of the location measure can be improved.

摘要： A first tag that is located in a communication coverage area among a plurality of tags is selected as a base tag in order to estimate tag location in an apparatus for estimating tag location that communicates with a plurality of tags. A second tag whose location is estimated among the plurality of tags is searched. First distance information of the second tag is estimated by performing a ranging procedure of the second tag. The second distance information estimated between the first tag and the second tag is received from the first tag, and the location information of the second tag is estimated by using the first distance information and the second distance information.
