Abstract: A location setting device of a compact base station through user input in a broadband wireless communication system and a method thereof are provided to obtain location information by using a GPS(Global Positioning System) signal and a user input address, thereby obtaining exact location information while the compact base station is easily configured and set. A GPS receiver(201) receives a GPS signal. A user input unit(203) inputs a home address from a user. A location information obtainer(205) compares strength of the received GPS signal with a threshold value, and if the strength is larger, the obtainer obtains self location information of a base station by using the GPS signal. If the strength is smaller, the obtainer obtains the self location information of the base station by using the inputted home address.
