Abstract
To provide a technique for analyzing radio wave condition affording improved accuracy of discrimination of radio wave propagation condition on a per-channel basis. Analyzer devicefor analyzing the condition of radio waves used for wireless LAN communications comprises a reception portionfor receiving radio signals in a plurality of frequency bands; a first strength sensing portionfor sensing the field strength RSSof the center frequency band on a per-channel basis from a received radio signal; a despreading portionfor despreading the received radio signal; a second strength sensing portionfor sensing the field strength RSSIof the center frequency band on a per-channel basis from the despread radio signal; a discriminating portionfor discriminating radio wave condition by cross-checking RSSIand RSSIon a per-channel basis; and a display portionfor displaying the discriminated radio wave condition.
