Analyzing technology of radio wave in wireless information communication |
摘要 |
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 device 10 for analyzing the condition of radio waves used for wireless LAN communications comprises a reception portion 410 for receiving radio signals in a plurality of frequency bands; a first strength sensing portion 420 for sensing the field strength RSS1 of the center frequency band on a per-channel basis from a received radio signal; a despreading portion 430 for despreading the received radio signal; a second strength sensing portion 440 for sensing the field strength RSSI2 of the center frequency band on a per-channel basis from the despread radio signal; a discriminating portion 450 for discriminating radio wave condition by cross-checking RSSI1 and RSSI2 on a per-channel basis; and a display portion 460 for displaying the discriminated radio wave condition.
