Abstract: PURPOSE: An apparatus and a method for arranging an access point for wireless measurement are provided to reduce time and manpower by determining an AP(Access Point) arrangement based on a simulation. CONSTITUTION: One or more APs are arranged on a digital map(S101). A location error is calculated according to a GP(Grid Point) on the digital map(S103). A first ratio of the GP with the location error with regard to the entire GP below a first threshold value is calculated on the digital map(S104). A GP ratio with a DOP(Dilution of Precision) with regard to the entire GP below the threshold value and the GP ratio with the phase error below the threshold value are respectively compared with the preset threshold values(S105). If the first ratio is below a second threshold value, one or more AP are rearranged on the digital map(S107).
