System and its method for notifying destination to public transportation users using uwb mobile

A destination announcement system using a UWB(Ultra Wide Band) portable communication terminal and a method thereof are provided to simplify control procedures and system configuration by receiving information on the next stop, based on UWB communication between a route guidance server, installed in a public transport means, and a passenger's portable communication terminal, and notifying the passenger that the arrival to his/her destination is close at hand. A route guidance server(2) comprises an antenna part(23), a UWB communication part(22), a storage medium part(24), and a central control part(21). The antenna part(23) transmits/receives radio signals to/from a portable communication terminal, based on UWB communication. The UWB communication part(22) transmits and receives radio data through the antenna part(23). The storage medium part(24) stores a route map program and route information of a public transport means. The central control part(21) executes UWB communication with the portable communication terminal, provides the route map program, receives destination information of the portable communication terminal, and periodically transmits the next stop information of the public transport means to the portable communication terminal.
