Packet Count
:
• Only an Admin / Advanced user can use Spectrum Analyzer to scan the spectrum. However, the Monitor user can
only view the last scanned results.
• The total duration of scan depends on the number of channels available and channel scan time.
• While scanning, Spectrum Analyzer does not consider channel offset.
• Spectrum Analyzer detects only 802.11 modulated signals.
• A minor variation in Spectrum Analyzer results can be expected due to the following reasons: variation in the radio
properties between various device models and Satellite Density Configuration.
• The frequencies are scanned based on the configured Scan Bandwidth slice starting from the lower edge of the
frequency filter, and displays the results captured at that particular instance.
6.2.2 Radio Link Test Tool
When there is a performance issue in the network, it is necessary to identify if the issue is related to wireless link or due to any
network parameters. Using the Radio Link Test (RLT) tool, you can measure and diagnose the performance issues in the
wireless link.
At MAC level, this tool internally generates traffic between the two radios, monitors the traffic, and generates a test report.
This test report helps to analyze the performance of the wireless link and other related issues, such as, interference, lower
throughput, and wireless errors.
Especially for the static link establishment, this is very helpful to check the link between the two radios when installing for the
first time or if any performance issues are noticed after the installation. If the link between the radios is of expected quality,
then there is no issue with the wireless link. In case, if there is any issue due to wireless parameters, the link may need some
tuning in configuration such as channel, Data Rate, Tx power or distance between the radios. In spite of all the testing and
tuning, if the performance still fails to improve, then it may be due to installation related issues such as antenna alignment or
the physical path. In the worst case, it may be a hardware related issue.
:
• This is not a replacement for other wireless performance measuring tools and should be used in conjunction with
other tools like Iperf or any other commercial tools.
• It is recommended to use this tool with caution on live networks as it will be generating internal traffic which may
impact the network performance.
• Radio Link test is an experimental feature and will be improved in future releases.
• This tool can be accessed through web interface, console commands, and CLI.
• Both ends of a link cannot simultaneously run this test.
•
For administrator and monitor user, go to the Summary page and click Link Test to access Radio Link Test
•
For advanced user, go to the Monitor > Statistics > Interface > Link Statistics > Details and click Radio Link Test.
Select the required type of traffic from the given options namely Outbound, Inbound, and Bidirection. Select Verbose
along with any one of the traffic options to get a detailed test report. Next, click the Start button.
