    摘要： Disclosed herein are an apparatus and method for providing communication services. The apparatus includes a location information acquisition unit, a radio station information acquisition unit, and an offloading unit. The location information acquisition unit acquires information about the current location of the user terminal by sending a location information request message to the user terminal. The radio station information acquisition unit requests information about a white space radio station from which the user terminal can receive the communication services by sending the information about the current location of the user terminal to a white space server, and acquires, from the white space server, information about an available white space radio station. The offloading unit sends the information about the available white space radio station to the user terminal, and also sends information about the user terminal to the available white space radio station.

    摘要： A multi-coexistence communication technology is provided. A multi-coexistence communication system based on an interference-aware environment and a method for operating the same can remove interference detected using an interference temperature limit from at least one transmission signal and transmit the signal to a main/sub communication terminal during data communication on a wired/wireless communication network formed of a main base station, a sub base station, the main communication terminal, and the sub communication terminal, thereby smoothly providing a high-speed seamless data transmission service based on a multi-coexistence communication environment where a distributed small-scale network requiring a low transmission rate, a medium-scale network for providing various wireless communication services, and a large-scale broadcasting network requiring a high transmission rate and high quality coexist, and preventing congestion due to increased demand for frequency resources.

    摘要： Disclosed is a wireless positioning system and method that can perform a high-precision position tracking. The wireless positioning system includes a target device that is an object of wireless positioning, beacon devices and a processing unit. The beacon devices transmits wireless signals and sense reception time points of the wireless signals transmitted from the other beacon devices and the target device and received at time points after the transmission of the wireless signal. The target device receives the wireless signal transmitted from at least one of the beacon devices, and then transmits the wireless signal to the beacon devices. The processing unit obtains the position of the target device by calculating distances between the beacon devices and the target device using information about the reception time points of the wireless signals sensed by the respective beacon devices.
