A system for measuring electric field strength of radio waves transmitted from cell station and arriving at an arbitrary measuring location is provided that includes a tuner unit, cell station ID (CS-ID) demodulator unit, signal level (or electric field strength) detector (RSSI detector), memory unit, display unit, and controller (CPU). CS-ID codes included in radio waves from cell stations and transmitted to an arbitrary measuring location are detected by the demodulator unit, and electric field strength (RSSI) data of the received radio waves are detected by the RSSI detector. All sets of the CS-ID and RSSI data are stored at addresses in the memory unit corresponding to each of the measuring locations, and the stored sets of the CS-ID data and RSSI data are read from the memory unit and displayed on the display unit in association with information indicative of the measuring location. |
