7.11.6 Radio Link Test Tool
: It is applicable to 82x / 8xxx devices.
In general, whenever the network has some performance issue, it is required to identify whether the issue is due to the
wireless link or due to other network parameters. The Radio Link Test (RLT) tool helps to measure and diagnose any
performance issues in the wireless link. At MAC level, this tool internally generates the traffic between the two radios,
monitors the traffic, and generates a test report.The test report will help in analyzing the wireless link performance 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.
