Title: RADIO-WAVE MAP GENERATION DEVICE AND METHOD
Abstract:
Disclosed are a radio-wave map generation device and method which collect radio-wave patterns by using user terminals of general users, generate a radio-wave map while dynamically adjusting the sizes of grids, and provide a real-time positioning service. The device for generating a radio-wave map within a building by communicating with one or more user terminals, according to one aspect, comprises: a processor; and a memory including at least one command which can be executed by the processor, wherein the processor receives, from the one or more user terminals, trajectory data and radio-wave data based on a trajectory, generates grids in variable predetermined units for the interior of the building on the basis of the trajectory data, and stores, in a database, the radio-wave map having the radio-wave data matched with each of the generated grids.
