RADIOWAVE STATE INTERPRETING UNIT, CONNECTOR CONNECTED TO WIDE AREA NETWORK, TERMINAL THEREOF, AND METHOD FOR DISCRIMINATING RADIOWAVE STATE, PARTICULARLY FOR DISCRIMINATING PROPAGATION STATE OF RADIOWAVE BY USING ELECTRIC FIELD STRENGTH DETECTED FROM RADIOWAVE SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide an analysis technology of a radio wave state for improving discrimination accuracy of a radio wave propagation state by each channel.;SOLUTION: An analysis apparatus 10 for analyzing a state of a radio wave used for wireless LAN communication is provided with: a reception section 410 for receiving a radio wave signal with a plurality of frequency bands; a first strength detection section 420 for detecting electric field strength RSSI1 of a center frequency band by each channel from the received radio wave signal; a spread demodulation section 430 for applying spread demodulation to the received radio wave signal; a second strength detection section 440 for detecting an electric field strength RSSI2 of a center frequency band by each channel from the radio wave signal subjected to spread demodulation; a discrimination section 450 for collating the RSSI1, RSSI2 by each channel to discriminate a state of the radio wave by each channel; and a display section 460 for displaying the discriminated state of the radio wave.;COPYRIGHT: (C)2004,JPO&NCIPI
