Claim 1:
2. A wireless communication characteristics evaluation method for evaluating wireless communication characteristics of a wireless communication system where a plurality of wireless communication terminals perform communication by transmitting or exchanging signals, the wireless communication characteristics evaluation method comprising: a step 1 of measuring power and a band of an interference signal; a step 2 of calculating an interference band rate using the measured interference power, where the interference band rate indicates a quantity of overlap between the band of the interference signal and a band of a desired signal; a step 3 of calculating an interference power rate from interference power and the interference band rate and furthermore, and calculating steady noise power from the interference power and the interference power rate; a step 4 of determining a real SINR from received power of the desired signal and the steady noise power; and a step 5 of determining wireless communication characteristics of the desired signal from the real SINR; wherein the interference power rate is calculated by acquiring-a modulation/demodulation scheme from a throughput value in a state in which there is interference at the interference band rate, acquiring an SINR at which transmission can be performed by the modulation/demodulation scheme from a datasheet, calculating real interference power from the SINR, and calculating a ratio of the real interference power relative to actual interference power as the interference power rate.
