質問 # 43
You are attempting to locate the cause of a performance problem in two WLAN cells in a mostly overlapping coverage area. You note that one AP is on channel 1 and the other is on channel 2.
When you document yoy findings, what term do you use to describe the problem in this configuration?
- A. CCI
- B. ACI
- C. Bluetooth interference
- D. Non-Wi-Fi interference
正解：B
解説：
Adjacent channel interference is more serious and occurs when 2 or more AP's are on overlapping channels, for example channel 1 + 4 on the 2.4Ghz band. ACI creates overlap in the frequency space causing corrupted data and layer 2 re-transmissions.
