The "muffer" command is used to analyze the electromagnetic environment. Allows to test the electromagnetic environment rapidly, visually estimate the efficiency of the radio links utilization, reveal interference sources, and estimate their power. Several "muffer" module operating modes allow to display different levels of details in test results.
The analyzer can be stopped by pressing the "Esc" or "Ctrl/C" keys.
|The interface identifier for which the radio environment is monitored.|
|MAC||CPE MAC address to analyze. If not specified, information is displayed for all CPEs.|
Allows to select MAC addresses analysis mode to estimate the number of clients with different MAC addresses and the efficiency of their radio link utilization.
Provides deep analysis of radio emission sources within the given network. In this mode, the device scans the radio spectrum on all frequencies and for all modulation types. Information is displayed on any source of irregular (non-repetitive) radio signals.
To obtain information as complete as possible, the scanning process may take significant time.
|-p||Allows to show the result as plain text (without the cursor control commands). It can be useful in case of including scan results in a diagnostic map or running scan process via web-interface (Remote Commands).|
|-tXX||Specifies the time duration, in seconds, for which the test mode is enabled (2 minutes by default). The "0" value cancels the time limit completely.|
|-lXX||Specifies the number of lines on the screen for displaying test results (24 lines by default).|
If specified, the analysis is carried out in the background, the results will be recorded in the system log.
sensor [record=SEC] [F1 [F2] [BW STEP]]
Enables the spectrum analyzer mode, provides deep analysis of radio emission sources. Information is displayed in a alphanumeric format.
Running "Spectrum Analyzer" mode disturbs normal operation of the radio module and makes it impossible to access the unit via radio.
The spectrum analyzer mode works on all platforms except H02.
Enables statistic mode which is used to estimate link load intensity for each client. The amount of packets sent and received, and the retransmissions number is shown for each MAC address participating in the data exchange. A large retransmissions number caused by a low signal level or a lot of interference leads to useless channel loading and decreasing the overall network bandwidth.
