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

PURPOSE: A radiowave state interpreting unit, a connector connected to a wide area network, its terminal, and a method for discriminating a radiowave state are provided to enhance precision of discrimination for propagation states of radiowaves in each channel. CONSTITUTION: A control unit(210) executes various types of processing related to interpretation of radiowave state in wireless LAN communication. A memory unit stores a result of the processing executed in the control unit(210) as data. An interface is connected to a radio card(30) to exchange data. A display unit(240) displays the result of the processing executed in the control unit(210). An RF unit(310) receives radiowaves of a frequency band used for the wireless LAN communication and performs processes for an analog signal until it is first demodulated. A baseband unit(320) spreads and demodulates the first demodulated radiowave signal. An MAC unit(330) processes a digital signal and performs various types of processing related to interpretation of the radiowave state in the wireless LAN communication.
