Methods and apparatus are provided for transmission and reception of signals. A signal is received that includes at least one of a power supply signal for wireless charging from a wireless power supplier and a power communication signal from at least one external wireless power receiver. The received signal is analyzed to determine whether the power communication signal is included with the power supply signal in the received signal. A transmission frequency of a transmission signal is determined based on whether the power communication signal is included with the power supply signal in the received signal. Transmission data for control of the wireless charging is modulated, and the modulated transmission data is output as the transmission signal over the transmission frequency.

Disclosed herein is an apparatus and method for analyzing information about floating population. The apparatus includes an information collection unit, a data integration unit, a data mining analysis unit, and an interface unit. The information collection unit collects information about locations provided by mobile communication terminals of moving objects, information about attributes of the moving objects, and information about locations and attributes related to stationary objects. The data integration unit creates integrated data by integrating the information collected by the information collection unit, national statistical information, and map data registered previously. The data mining analysis unit extracts data, consistent with conditions input by a system user, from the integrated data, and searches the map data for based moving patterns of the moving objects using data mining analysis. The interface unit provides a map service in which search results have been applied to the map data.
