1. An apparatus for access point (AP) placement of large-scale wireless LAN and adaptive wireless resource management, the apparatus comprising:
a layer environment simulator configured to simulate a layer environment expressing status of an AP through collected data;
a constraint condition checker configured to select an existing location for initial AP placement and check a constraint condition at the existing location;
an AP placement determinator configured to add an AP if the constraint condition checked by the constraint condition checker is not satisfied;
an STA change size decider configured to decide a size of STA change over time; and
a wireless resource change manager configured to change wireless resources when the STA change over time is greater than a reference α, otherwise maintain the original status,
wherein the layer environment simulator comprises a data expression part configured to add up the number of connected devices of one AP by averaging values of 2.4 GHz band and 5 GHz band, and maintain a matrix for ratios and use rates of channels used by APs.
