CINR (dB)
>28 Higher modulations are available
Absolute value Crosstalk (dB)
>20 Recommended value
If the value of the RSSI parameter remains high while the CINR value decreases, it may indicate high interference
levels near one of the devices.The deterioration of both the RSSI and the CINR parameters can indicate a
misalignment of the devices.A detailed description of the "Antenna Alignment" tool is available in the"Device
status menu(see page 73)"article.
Command line interface
When using the command line to manage the device, fine antenna alignment can be performed using the "ltest rf6.0
MAC ADDRESS -align

" command.The command output will show the average CINR for the local and the remote
devices.

Some device modes and options can significantly affect the link's stability and throughput.

8.5.1 Autobitrate and ATPC
To keep a balance between the wireless link's performance and the retries number, we recommend to alwaysset
the "Bitrate" parameter to "Auto" mode.Also enable the automatic transmit power control (ATPC) in order to
increase the operational life of the devices.
