Claim:
1. An apparatus for controlling transmission power, the apparatus comprising at least one hardware processor to implement: a transmission power calculation unit configured to calculate a desired transmission power value for a terminal of a type, the terminal being accessible to one or more wireless networks; and a transmission power setting unit configured to, when an access of the terminal to at least one of the one or more wireless networks is sensed, provide the terminal with desired transmission power values corresponding to the terminal and the wireless network accessed by the terminal, wherein the transmission power calculation unit is further configured to calculate a desired transmission power value for each of one or more access points included in a specific wireless network selected from among the one or more wireless networks, and to calculate a desired transmission power value of the specific wireless network from the calculated desired transmission power value for each access point, wherein the transmission power calculation unit is further configured to measure a service area of a specific access point selected from among the one or more access points using a forward transmission quality between a test terminal and the specific access point, and to calculate a minimum transmission power value at which the test terminal is configured to enable communication in the service area using a reverse transmission quality between the test terminal and the specific access point, wherein the transmission power calculation unit is further configured to measure a plurality of forward transmission qualities while moving the test terminal in a preset plurality of directions from one point on a ground closest to the specific access point, to select a plurality of communication points corresponding to the plurality of directions from the measured plurality of forward transmission qualities, and to set the service area of the specific access point based on the selected plurality of communication points.
