5. Number of undelivered acks value in «ua%» columns must be zero; if this

value is not zero then the radio link couldn’t be exploit. If this value is

constantly not less then 50 then most probably «distance» parameter is

set with a wrong value. If radio link distance is more than 20 km then

«long» mode must be enabled.

ALL described parameters must be observed in the both (Local and Remote)

sections of the «ltest» command output.

Alignment mode (for Xm-series only):

The difference of this mode from the standard one is that «ant.amps» column is

used instead of «amp/max». «Ant.amps» column indicates signal levels for each

of two antennas of a devce divided by “:” correspondingly.

To start Ltest in this mode:

lt rf5.0 <Mac-adress> -align [L,R]

Ltest output in alignment mode:

Bandwidth mode (Bandwidth meter):

Bandwidth meter is used to test the following radio link characteristics:

throughput in kilobits per second, packets per second, number of retries and

errors.

Use the following «

ltest

» command options for testing:

• -tu [seconds] – Unidirectional test: packets are transmitted only

from the current side to the specified address (“

target

” option)

• -tb [seconds] – Bidirectional test: packets are transmitted in both

directions

“

Seconds

” parameter allows setting test period (5 seconds by default). Maximum

value is 60 seconds.

To start Ltest in this mode:

lt rf5.0 <Mac-adress> -tb

“Ltest” command output in Bandwidth meter mode:
