Description

This command shows the interference power detected by a 802.11a or 802.11g radio on a spectrum monitor or hybrid AP. This table displays information about AP power levels, channel noise, and adjacent channel interference seen on each channel by a spectrum monitor or hybrid AP radio.

The output of this command displays the noise floor of each selected channel in dBm. The noise floor of a channel depends on the noise figure of the RF components used in the radio, temperature, presence of certain types of interferers or noise, and the width of the channel. For example, in a clean environment, the noise floor of a 20 MHz channel will be around -95 dBm and that of a 40 MHz channel will be around -92 dBm. Certain types of fixed frequency continuous transmitters such as video bridges, fixed frequency phones, and wireless cameras typically elevate the noise floor as seen by the Wi-Fi radio. Other interferers such as the frequency hopping phones, Bluetooth, and Xbox devices may not affect the noise floor of the radio. A Wi-Fi radio can only reliably decode Wi-Fi signals that are a certain dB above the noise floor and therefore estimating and understanding the actual noise floor of the radio is critical to understanding the reliability of the RF environment.

Interferen ACI列显示ce Power Chart displays Adjacent-Channel Interference (ACI) power levels based on the signal strength(s) of the Wi-Fi APs on adjacent channels. A higher ACI value in Interference Power Chart does not necessarily mean higher interference since the AP that is contributing to the maximum ACI may or may not be very actively transmitting data to other clients at all times. The ACI power levels are derived from the signal strength of the beacons.
